Special turbines for shot blasting in the forge and foundry industry

30 percent longer service life and lower operating costs The special version of the easy to maintain Rösler blast turbines Gamma 400G-8 has been perfectly adapted to the harsh blasting conditions in foundries and forge shops. Designed with 8 throwing blades and made from extremely wear resistant tool steel, the Gamma 400G-8 turbines offer an up to 30% longer service life than conventional turbines. Moreover, the Y-design of the throwing blades ensures a more effective and energy efficient acceleration of the blast media. This results in lower operating and maintenance costs combined with a significantly higher equipment availability. Sand, oxide, scale and residue from the tempering process on castings and forgings inevitably cause the blast turbines to wear a lot faster and lead to higher operating and maintenance costs. Rösler Oberflächentechnik GmbH has tackled this problem head-on by developing the Gamma 400G-8. This turbine variant is especially wear resistant and offers the ideal solution for such challenging shot blasting applications. It can be easily installed in all turbine shot blast machines irrespective of the original manufacturer. Equipped with a power input of up to 37 kW, the direct drive Gamma 400G-8 turbines allow a blast media throughput of up to 460 kg/minute. 8-bladed wheel design and tool steel guarantee a longer service life A key feature of these special turbines is the 8-bladed wheel design ensuring a greatly improved blast pattern. In addition, the forged throwing blades, impeller and control cage are made from high-quality, extremely wear resistant forged steel. Likewise, the turbine housing is lined with the same material. Compared to conventional turbines, this results in an up to 30% longer service life. And the patented Y-design of the blades allows using both blade sides, which practically doubles their usable life. An innovative quick-change system allows a quick and easy blade change without having to touch the other turbine components. The time consuming dismounting of impeller, control cage and inlet tube is no longer necessary. Improved performance and higher energy efficiency Another advantage of the Y-design with the precisely calculated blade curvature is a considerably better performance that expresses itself by a significantly higher throwing speed and a highly precise blast media delivery. The resulting improvement of the blast performance requires much shorter cycle times. Finally the energy efficient blast media delivery reduces the energy consumption by up to 15%. All these features uniquely qualify the custom-engineered Gamma 400G-8 turbines for use in foundries and forge shops. They offer a tremendous potential for not only reducing the operating and maintenance costs but, at the same time, increasing the shot blast capacity and overall cost-efficiency.

Mass Finishing Media, Part 2 – Tips for Measuring Media-to-Work Piece Ratio

Maintaining the right ratio of media to work pieces is essential to achieving precise, repeatable results in mass finishing processes where work pieces and media loosely tumble in the processing bowl. Ensuring that the work pieces are properly embedded in the media allows the media to perform its designated grinding or polishing function as well as cushioning the work pieces from damage caused by part-on-part impingement. Building upon our last post on the series about navigating the complex media selection considerations , Rosler’s team of experts now discusses tips for determining the best media-to-work piece ratio. Basic Rule of Thumb The standard ratio of media to work pieces is around 3-to-1 by volume – meaning that the mix is 3 parts media to 1 part of work pieces – but the exact ratio varies based on the aggressiveness of finishing required as well as the work piece’s material, shape, size, weight, and delicacy or lack thereof. For simple, sturdy work pieces, the ratio may be lower than the standard while work pieces that are very delicate; made from soft, heavy metals; or must receive a high-gloss polish require a much higher ratio of 10-to-1 and higher. Typically, media-to-work piece ratios increase with the more extreme smoothing and finishing, higher material softness, large and heavy work pieces, and those with more complex or fragile construction. The basic rule of thumb for the ratio of media to work pieces in mass finishing. Pinpoint Your Ratio Determining the exact ratio for your mass finishing process requires digging a bit deeper into your specific media and machine specifications. Determine the “usable volume” in cubic feet of the processing bowl. This information is usually supplied by the equipment manufacturer. Determine the number or weight of work pieces that fit into 1 cu ft, e.g. for small parts use a 12x12x12” shipping box and transfer parts until the box is full. Use the bulk density of the specific media type to calculate the required media quantity by weight. For reference: Ceramic media = 95 - 105 lbs/cu ft Porcelain and high density media = 115 - 145 lbs/cu ft Plastic media = 70 - 85 lbs/cu ft An Example The usable volume of a processing bowl is 12 cu ft and the desired ratio is 5-to-1. Therefore, 10 cu ft of media and 2 cu ft of work pieces should be filled in the machine. We’ve determined that 50 work pieces fit into 1 cu ft so you would place 100 work pieces into the machine. If we were dealing with small, bulk goods, we would measure out 2 cu ft instead of counting individual pieces. Let’s assume we’re using ceramic media which weighs around 100 lbs/cu ft. Because we need 10 cu ft to balance out the work pieces, we will need 1,000 lbs of media. If we were using plastic media, the total would be around 750 lbs; high-density media would require about 1,400 lbs. Process Observation Once established, the initial media-to-work piece ratio must be constantly monitored. If the ratio becomes too low, new media must be added. Equipment updates may be available to help maintain the optimal media levels. For certain applications, timer- or widget-controlled media replenishment systems may be beneficial.

Компания HP и бренд AM Solutions группы Rösler представляют инновационную 3D автоматическую станцию распаковки для 3D-принтера HP Jet Fusion серии 5200

Компания HP и бренд группы Rösler AM Solutions 3D post processing technology представляют инновационную 3D автоматическую станцию распаковки, являющуюся первым совместно разработанным продуктом в результате сотрудничества, заключенного в 2019 году. Масштабируемое и применяемое в промышленных условиях решение для постобработки позволяет осуществлять полностью автоматизированную и воспроизводимую распаковку деталей, изготовленных методом аддитивных технологий с использованием 3D-принтера HP Jet Fusion 5200 3D-Druck-Systems в непрерывном производственном процессе. Наряду со значительным увеличением производительности и улучшенным показателем эффективности затрат, 3D станция позволяет добиться определенно значительной степени вторичной переработки порошка в сравнении с ручной распаковкой в зависимости от геометрии заготовки. Производством 3D автоматической станции распаковки занимается подразделение 3D post processing technology бренда AM Solutions группы Rösler. Являясь ведущим мировым поставщиком промышленных решений для 3D-печати и цифрового производства, компания HP уже на раннем этапе пришла к выводу, что для проведения успешной индустриализации 3D-печати, необходимо печать и последующую обработку деталей преобразовать в автоматизированную, масштабируемую технологическую цепочку. Для реализации этого процесса были созданы все условия благодаря заключенному в прошлом году договору о сотрудничестве с подразделением 3D post processing technology бренда AM Solutions группы Rösler, основным направлением которого является разработка решений для последующей обработки деталей, изготовленных методом аддитивных технологий. На сегодняшний день уже существуют решения для 3D-принтеров, а в особенности принтеров, использующие технологию HP Multi Jet Fusion, тогда как ранее процесс последующей обработки до сих пор был сопряжен со многим манипуляциями, требующие ручного труда. С внедрением 3D автоматической станции распаковки, специально разработанной для 3D-принтера HP Jet Fusion серии 5200, в процессе постобработки появились изменения. Первая совместно разработанная установка в сотрудничестве компании HP и подразделения AM Solutions — 3D post processing technology, объединила в себе передовые разработки в программном обеспечении и инновации в области материаловедения Hewlett Packard и многолетний опыт производителя Rösler, насчитывающий уже более 80 лет в сферах обработки поверхности и машиностроения для промышленного применения. Воспроизводимая быстрая распаковка и высокая степень вторичной переработки порошка Автоматический процесс распаковки начинается сразу же после охлаждения задания печати в блоке натурального охлаждения. При помощи специального подъемника осуществляется перемещение блока натурального охлаждения к 3D автоматической станции распаковки. После установки блока натурального охлаждения на верхней платформе автоматической станции распаковки, следует автоматическая разблокировка и печатные макеты поступают внутрь станции. Считыватель RFID-меток идентифицирует по радиочастоте задания, содержащиеся в устройстве натурального охлаждения, и передает их в управление автоматической станции распаковки. Cистема обеспечивает отслеживание данных печати и технологического процесса, а с помощью программного обеспечения HP 3D Center - дистанционный контроль процесса распаковки. Кроме того, благодаря автоматизированному процессу распаковки, в зависимости от геометрии отдельных деталей, возможно извлечь значительно больше порошка для повторного использования. Непрерывное удаление остаточного порошка из автоматической станции осуществляется пылесосом и собирается во внешнем контейнере. После завершения процесса автоматической распаковки, детали поступают в разгрузочный бокс. Для замены заполненного порошком внешнего контейнера используется пустой контейнер. Загрузку использованного оборотного порошка из внешнего контейнера снова в бокс HP Build Unit можно осуществить, использовав станцию 3D Processing. Новая 3D автоматическая станция распаковки не только сводит к минимуму ручное вмешательство, но также сокращает время обработки для определенных приложений, поскольку к процессу распаковки можно приступать сразу после истечения рекомендуемого минимального времени охлаждения. «Новые решения для масштабируемой, эффективной постобработки и автоматизации рабочего процесса являются ключом к полному использованию потенциала аддитивного производства и его внедрению в серийное промышленное производство», - отметил Рамон Пастор, Генеральный директор и глава подразделения HP 3D Printing & Digital Manufacturing. «Наш партнер - Rösler / AM Solutions является опытным специалистом в сфере промышленных стандартов различных отраслей и обладает всем необходимыми ноу-хау как в области обработки поверхностей, так и в машиностроении». Штефан Рёслер, Президент и Генеральный директор компании Rösler Oberflächentechnik GmbH, отмечает: «Высокая компетенция компании HP в области 3D-печати, программного обеспечения и цифрового производства позволяет нам ускорить внедрение применяемых в промышленных условиях инноваций для 3D-постобработки и целенаправленно адаптировать разработки продуктов в соответствии с требованиями промышленных пользователей». Маттео Ригамонти, основатель компании Weerg, подтверждает это: «Станция автоматической распаковки HP 3D действительно оправдала наши все ожидания. Процесс автоматической распаковки стал не только намного быстрее, но и предоставляет возможность извлекать больше порошка. Станция автоматической распаковки хорошо обрабатывает даже малогабаритные и чувствительные детали». Компания, базирующаяся в итальянском Скорце, производит около 2500 деталей в день в 3D-печати и испытала новую установку на производстве в тестовом режиме. «По мере модернизации нашего предприятия эти расширенные возможности должны помочь нам в стремлении удовлетворить потребности клиентов и сократить время выполнения заказов для серийного производства», - добавил Маттео Ригамонти.

Automotive Supplier Achieves Process Stability, High Cost Efficiency with Modular Shot Peening System

For transmission components like gears and shafts, shot peening has become an indispensable step in the overall manufacturing process. With the RWT swing table machine, Rosler developed a modular equipment concept that can be easily adapted to different technical requirements and offers a maximum in process stability paired with absolutely repeatable peening results and high cost efficiency. One of the numerous customers within the automotive industry utilizing the RWT is an Asian automotive supplier. The Need As part of a capacity expansion for minivan transmissions, this customer increased annual production to 40,000 units and decided to carry out the required shot peening operation in-house instead of subcontracting it to an external job shop. The specifications called for a system that can handle around 560,000 single work pieces per year, including 15 different types of gears and shafts. Each work piece type required the development of a specific peening program based on drawings and various work piece materials. Another requirement was the tight control of the entire peening process capable of handling gears and shafts with diameters of 12 in (300 mm), heights of 20 in (500 mm), and weights of up to 55 lb (25 kg). The Solution The customer chose the Rosler shot peening system RWT 13/4 So due to its capability and fully automatic processing. This pressure blast system includes a table with two 180° segments, each equipped with two satellite stations which allows two parts to be processed in one segment while another pair of parts is loaded/unloaded in the other segment. For complete coverage of the work pieces, the RWT is equipped with four blast nozzles – two for vertical and two for horizontal movement. Since some areas of the work pieces are completely finished before entering the machine, special wear-resistant masking is integrated into the work piece fixtures to protect the already finished surface area from being blasted. To meet all customer requirements, the system design allows the parallel use of two different blast media types or one type with different shot sizes. Rosler tested various work pieces during the course of the project. Rosler’s global test centers and the in-house X-ray diffraction measurement capabilities showed that the achieved compressive stress values were twice as high as the values stipulated by the customer. The in house X-ray diffractometer allowed Rosler to shorten the process development cycle for these transmission components. The measurement system can also be used for a variety of other parts besides gears and shafts. These can include valve and chassis springs, other chassis components, airplane turbines , and components for the energy generating industry. Rosler also offers x-ray diffraction measurements as a service . Developed for Success The RWT’s concept can easily be adapted to specific customer requirements since its swing table design is based on a modular concept developed for shot peening of rotationally symmetrical components. The RWT's blast chamber Compared to other peening systems on the market, the blast chamber contains considerably more wear protection and is easier to access for maintenance work. The pressure blast system requires a considerably lower amount of compressed air and, therefore, runs more efficiently. The RWT's monitoring and control system A comprehensive monitoring and control system measures the air volume to ensure the high process safety and consistency required for any shot peening operation. The RWT's blast nozzles The nozzles can be moved vertically and horizontally as well as pivoted at an angle from 0 to 90°. This guarantees complete coverage of all work piece surface areas over a large part size variety. The high efficiency of the pressure blast system results in significant savings in compressed air consumption. For controlling the overall peening process Rosler also uses standard components. These include the automatic control of the blast media throughput and the precise measurement of the media throwing speed directly at the nozzle exit. The Magna valves for precise dosing of the blast media as well as all media hoses can also be monitored. The RWT can be equipped with a spiral separator for discharging any broken-down blast media. The Rosler Way With more than 80 years of experience, Rosler has the knowledge and expertise to find the exact shot peening machine to meet your needs.

Blast equipment modernization and upgrade – an efficient alternative to buying new

Turbine replacement results in a 45% higher blast performance and lowers operating costs by one third Growing maintenance and operating costs combined with a declining blast performance; these are usually good reasons for investing in a new shot blast machine. By taking advantage of the Rösler Retrofit program for a shot blast machine in its foundry division a leading company for drivetrain technology and electronic controls chose a significantly less expensive but highly effective alternative. The existing shot blast machine was upgraded with the foundry version of the Rösler Gamma 400G-8 high performance turbines. This turbine upgrade helped reduce the expenses for maintenance by two thirds and the overall operating costs by more than 34%. At the same time, the blast performance could be increased by 45 percent. This resulted in an amortization time of a little over one year. The turbines in shot blast machine must carry a heavy load and are exposed to a lot of stress. Over time this leads to ever increasing maintenance and operating costs along with a growing energy consumption. Frequently, the blast performance no longer meets the capacity and quality demands. In order to fulfill their shot blasting requirements in a cost-efficient and competitive manner companies usually invest in a new shot blasting system. A persuasive modernization solution with a quick amortization A renowned manufacturer of drivetrains and electronic controls was facing exactly this problem with a shot blast machine in its foundry. The responsible project managers at the company contacted TuneUp, a division of the Rösler Oberflächentechnik GmbH, that specializes in the modernization of shot blast equipment . On this occasion they learnt that the Rösler modernization and upgrade service covers not only Rösler equipment but extends to third-party machinery as well. After a comprehensive analysis of the current equipment condition the Rösler Retrofit experts presented a suitable technical solution along with a realistic amortization calculation. The customer was impressed by the technical depth and short pay-back period of the proposed modernization concept. Turbine replacement increases productivity and lowers costs At the center of the modernization concept was the replacement of the two 22 kW turbines originally supplied with the shot blasting machine. The existing units were exchanged with high performance Gamma 400G-8 turbines in wear-resistant foundry version, also with a drive power of 22 kW each. They are equipped with eight curved throwing blades in „Y“-Design with a precisely calculated curvature. This generates an extremely high throwing speed along with a precise media guidance and results in an optimal efficiency. The unique characteristics of the Gamma turbines with a 45% higher blast performance allowed achieving the needed capacity increase. Another feature of the new high performance turbines is that they require a lot less energy. The energy savings were an important reason for the overall operating cost decrease of 34%. Expenses for maintenance reduced by over two thirds The unique design of the throwing blades produces not only a higher performance but allows using both blade sides by simply turning them around. Depending on the utilized blast media, this design feature, combined with the use of wear resistant blade material, for example, forged tool steel, results in a three times longer lifetime compared to conventional turbines. An innovative quick-change system allows easily and quickly changing the blades at the mounted turbine. The usually required time-consuming dismounting of impeller, control cage and infeed pipe is no longer necessary. Overall this reduces the expenses for maintenance by more than two thirds. Quick amortization produces a competitive edge Based on the capacity utilization to-date, the productivity increase achieved by the upgrade and the cost savings the Retrofit investment will have paid for itself already after 1.1 years. The technical features of the modernized shot blasting machine and the quick amortization allow the user to improve his profitability and consolidate and expand his competitive position in the market.

Mass Finishing Media, Part 1 – Don’t Navigate the Complex Selection Process Alone

The importance of the media selection in any surface finishing process cannot be emphasized enough. These consumables are essential “precision tools” for achieving the specified finishing results. Selecting the right media is a complex task. That’s why you should consult an expert such as Rosler for guidance. Even after a mass finishing process has been established, the media status must be constantly monitored and, if necessary, corrected. When different work pieces are processed or finishing tasks are altered, exchanging the currently used media type with another may be required. Careful and collaborative media selection is crucial to a mass finishing success. Consider the Characteristics The work pieces should always be at the center of the media selection process and take into consideration its starting surface burr condition, material, shape, size, and desired surface finish. Media characteristics must complement the work piece as well as the machine being utilized. Media characteristics to consider in relation to work pieces and the machine utilized include: Bond – Ceramic media generally has a higher density than plastic media , making ceramic more aggressive. While typically more gentle, plastic media can sometimes produce unwanted foam known as “dirt foam.” Type/Abrasiveness – Deburring/edge radiusing and/or aggressive surface grinding require a more abrasive media than gentle surface smoothing. Shape – Media may have to reach very tight corners and internal passages. Choosing the right media shape is crucial for reaching all critical surface areas. Size – Always choose the largest possible media that fulfills the finishing tasks for the most efficient process. Lodging issues – Media lodged in the work piece can have disastrous consequences for downstream manufacturing. Selecting a media shape and size that prevents lodging is crucial. Color – Choosing a media color that differs from the work pieces helps identify lodging issues. Potential for damage – For delicate work pieces, gentle yet effective media must be selected to avoid bending thin walls or damaging critical sealing areas requiring a tight fit. Separation – Reliable media separation from the finished work pieces must be allowed by screens, inverse screens, magnetic separators, or, in extreme cases, manual separation. Intensity – More intensive machines such as centrifugal disc systems or drag finishers usually require smaller, less abrasive media than vibratory models such as rotary and tub vibrators . Analyze Ongoing Costs Since finishing media is a consumable that wears and must be regularly replenished, cost is an ongoing concern. In some finishing process, the expenses for media account for more than 50% of the total process costs. Therefore, it is important to select a media that is both economical and effective to maintain a viable mass finishing process. While media costs also play an important role in the selection process, media choice should never be determined by price per pound. Instead, the media cost per work piece should be a guiding factor. For example, a lower priced media might require much longer processing times or wears a lot faster and would therefore be less economical than a higher priced media that achieves the desired finishing results in less time and has a lower wear rate! Rosler Testing Center Partners in Testing Whether your process uses ceramic, plastic, or drying and polishing media , a crucial step in selecting media should always be contacting the experts, i.e. your supplier. Since a media change might require extended test trials, your supplier should partner with you to test prospective media with your specific work piece in their test lab.

Forge & Foundry, Part 12 – Media and Compound Selection, Effluent Handling Drive Success

Regardless of the industry , the selection of media and compounds utilized in mass finishing can elevate or hinder finishing results. The handling of effluents – used process water – also factors into a process’ efficiency and end results. With more than 80 years of experience, Rosler understands the demands of the forge and foundry industries specifically and how to achieve precise and consistent finishing results by combining the latest technology, well-designed machines, and consumables . This installment of the Forge & Foundry Blog Series highlights how careful media and compound selection along with proactive handling of effluents assist in producing mass finishing efficiencies. Ingredients for Success Media and compounds are more than just “rocks” and “soap” thrown into a mass finishing machine. Instead, these consumables are sophisticated tools that can make a mass finishing process a success or a failure. Media choice with regard to shape, size, composition, and abrasiveness is as important as selecting the right machine. Selecting the wrong media could be detrimental to the process. The level of media in a machine is equally important. If not introduced in the prescribed ratio, even the best suited media will fail to deliver the desired results. For example, increasing the ratio of media relative to the work pieces has a cushioning effect and helps prevent unwanted work piece damage in the form of nicking. Conversely, skimping on media levels can produce ineffective finishing as well as work piece damage. Much like media, the compound selection must match the work piece material. For example, aluminum die-castings require a different compound than die-castings made from magnesium. Applying compounds in the prescribed dosage is also key to maintaining finishing results. For example, insufficient compound usage can cause foaming in the machine and discoloration of finished work pieces. Handled with Care Mass finishing produces an effluent containing media and metal fines, various chemicals from the compounds, and sometimes even chelated metals. At this point a decision must be made; will the effluent be cleaned and recirculated or discharged as waste? In either case, contaminants must be removed first. When discharging as waste, all contaminants must be removed to prevent pollution issues and discharge fines. Additional mass finishing process efficiency and greater ROI can be attained by cleaning effluent for reuse. The use of centrifugal filters is an excellent treatment method for effluent which factors in added benefits including reduced water usage and compound longevity. Rosler Centrifuge Technology By removing all solids in the form of media and metal fines from the mass finishing effluent, centrifuges allow the cleaned liquid, now free of any solids, to be reused by recycling it back to the mass finishing machine. This can result in water consumption savings of more than 90 percent. Since centrifuges do not degrade the compound in the process liquid, drastically reduced usage of compounds may also be achieved.

Mit dem neuen Dosiersystem von Rösler gesetzeskonform arbeiten

In der im August 2017 in Kraft getretenen 42. Bundesimmissionsschutzverordnung (42. BImSchV) werden vom Gesetzgeber Maßnahmen vorgeschrieben, um die Bildung von gesundheitsgefährdenden Legionellen-Stämmen zu verhindern. Dies betrifft auch das Betreiben von Nassfilter. Die Verordnung verpflichtet u. a. alle Betreiber von Nassabscheidern, regelmäßig aufwendige Prüfungen und Laboruntersuchungen auf Legionellen-Befall durchzuführen und zu dokumentieren. Bei Unterlassung drohen erhebliche Strafen. Unsere Lösung: Auf Grund unserer langjährigen Erfahrung im Umgang mit Prozesswasser, haben wir für alle Nassabscheider ein System entwickelt, dass die Entstehung von Legionellen gänzlich verhindert. Durch Einsatz unserer neuen Dosiereinheit RDS-pH 10/25 in Kombination mit unserem Verfahrensmittel Additiv RST-P1 wird der pH-Wert des Nutzwassers dauerhaft über 10 gehalten. Dies wird automatisch dokumentiert. Das Entstehen von Legionellen wird dadurch im Vorfeld verhindert, Laboruntersuchungen können entfallen und gesetzliche Vorgaben werden zu 100 % erfüllt. Ihr Nutzen: Das Entstehen von gesundheitsgefährdenden Legionellen-Stämmen wird auf einfache Weise verhindert Kosten und Aufwand für Laboruntersuchungen entfallen Vermeidung von hohen Ausfallkosten durch eine notwendige Anlagenreinigung nach einem möglichen Legionellen-Befall Automatische Protokollierung des pH-Wertes im Nutzwasser in ein Betriebstagebuch Geringer Überwachungs- und Wartungsaufwand Kein Aufwand bei Stilllegung zur Urlaubszeit sowie bei der Wiederinbetriebnahme danach Wir beraten Sie gerne weiter.
