Automation, Part 5 – What Automation Hardware is Available?

As previously discussed in our Automation Blog Series, building a robotically assisted process requires evaluating your surface finishing system along with its problems and goals and selecting the right machine and consumables . Automating a mass finishing or shot blasting process also requires selecting the automated hardware that will best achieve your overall goals and provides the most efficiency in terms of time and manual labor. An experienced partner such as Rosler Metal Finishing can provide insight and advice on the numerous material handling tools specially designed or adapted to mass finishing and shot blasting process improvement. Work Piece Loading Systems Including skip loaders, lift and tip loaders, vibratory feed hoppers, and other tools, work piece loading systems are ideal for small- to mid-sized work pieces handled in bulk. A lift and tip loader with integrated vibratory hopper is included in this Rosler FKS mass finishing system. These loading systems can be movable—for example, on rails—to serve several machines. They can also be placed on weighing cells to determine the exact work piece quantity by weight and adjust machine loads accordingly. This RMBC Tumblast Machine from Rosler is equipped with a skip loader. Conveyor Belts Used for loading and intermediate transport, conveyor belts are commonly used for mid-sized to larger work pieces. These belts must be able to withstand moisture and sometimes harsher industrial conditions. They must also be well-sealed to prevent aggressive liquids or abrasive media from destroying their drive systems and bearings. This Rosler DA system is equipped with part and media conveyors on an inline vibratory machine. Part and media conveyors on an inline vibratory machine Roller Conveyors Commonly used to transport large, heavy work pieces such as large steel beams and plates, roller conveyors are also utilized for automatic staging of raw parts and backfilling finished parts into part bins. Roller conveyors on this Rosler FKS mass finishing system stage finished work pieces. Steel plates and beams are transported through this Rosler RRB shot blast machine via roller conveyors.

Consumable Innovations Improve Finishing Outcomes

True to our mantra of “finding a better way…” Rosler Metal Finishing is constantly working to optimize our consumables . These improvements and additions to our offerings improve process stability, cost efficiency, and productivity of surface finishing processes. From media composition and compounds to wastewater handling, Rosler is dedicated to constant enhancement in the area of consumables as well as our mass finishing and shot blasting technology. Media One such example is Rosler’s development of a plastic media with the grinding and non-chip characteristics of ceramic media . Minimizing the risk of work piece damage, this range of high-density plastic media exactly achieves this frequently requested combination. High-density plastic media Through their special composition, these plastic grinding media have the same grinding and metal removal characteristics as their ceramic “siblings” yet demonstrate a higher elasticity. This media type also allows faster processing of delicate work pieces made from non-ferrous metals as well as parts that tend to bend during the finishing process. Liquid, Pumpable Pastes Another breakthrough are the liquid pastes in the RSP and RPP 8 range. These innovative KeramoFinish® pastes, even though relatively viscous, can be delivered into the machine through a pump and thus can be dosed more precisely in line with the given processing requirements. Liquid, pumpable paste in the RSP and RPP 8 range Automatic dosing systems allow further optimization of the overall process. The utilization of such sophisticated dosing systems helps improve process controls and has proven that the desired finishing results can be achieved with less personnel. Granulated Wastewater Cleaners New developments can also be reported from the field of wastewater cleaning with recycling systems. Granular pellets are replacing the powder products that were previously used for flocculation and improvement of the sludge consistency. Granualated flocculant Granulated flocculants have several advantages. They allow optimized handling without the risk of dust, thus contributing to improved workplace safety. Granular versions also prevent so-called “bridge building” in the dosing units, which can lead to a dosing fault. The new granulated flocculants can be dosed with existing dosing units and achieves more precise dosing. Precision is very important for processes where process water tends to foam. All these characteristics, in combination with the mechanical stability of the granules and short reaction times, ensure a significantly improved process stability. New development consumables The Rosler Way Finding a better way is more than a saying at Rosler; it’s our passion. We strive to outdo ourselves with each innovation and upgrade in order to offer our clients the most-advanced and best-suited finishing technologies and products. Contact us to discuss your unique challenges and how we can innovate a solution for your needs and goals.

Automation, Part 4 – Choosing the Right Machine and Consumables

Rosler Metal Finishing understands that automation integration requires careful planning to ensure the best, most efficient results. Whether for mass finishing or shot blasting , we have more than 80 years of experience helping customers match machines and consumables . Taking time to evaluate your process needs as a whole will help you and a trusted partner such as Rosler determine what machine and consumables will best suit your automation needs and goals. How do I choose the right machine? Selecting the right machine is the most critical step to ensure the success of any automation project. Without the right machine, your automation process is sure to fail or produce disappointing results. In order to choose the right machine for your needs, consider: The size, shape, and weight of the work pieces – If you were looking to deburr the links for chainsaw chains, for example, you would need a completely different machine than one that de-sands/descales sand castings which weigh substantially more. Batch vs. continuous feed operation – Can the work pieces be collected in batches and processed as such or must they be continuously fed into the machine, one after the other? Part-on-part interaction – Are the work pieces sturdy and able to tumble over each other or must part-on-part contact be prevented? This determines whether each work piece must be placed on a fixture and processed individually to avoid contact or whether contact between work pieces is acceptable. Rosler’s Tumblast Machine model RMBC is an example of a batch-based process. Sturdy work pieces that are not subject to nicking as a result of part-on-part contact freely tumble inside. Work pieces are continuously processed in Rosler’s R 650/6600 DA Inline Continuous Flow Vibrator and automatically loaded and separated. How do I choose the right consumables? Selecting the most appropriate consumables is as important as deciding on the right machine. Just as mass finishing and shot blasting machines offer different strengths and capabilities, so do the media and compounds used within a given process. Therefore, special care must be taken in choosing the best-suited consumables and making sure that they are fully functional within the scope of an automatic operation. Choosing the wrong mass finishing media can produce poor finishing results and cause media to lodge in the work pieces, which can defeat the whole purpose of automation. Poorly selected media shapes and sizes can lead to problems such as ineffective finishing and media lodging within the work pieces as shown. The surface finishing experts at Rosler can help match consumables to your process needs and incorporate automation to load, unload, classify, recirculate, and monitor the levels of consumables including: Compounds . Ceramic media . Plastic media. Polishing and drying media . Shot blasting media . Along with choosing the right consumables, it is also important to include a good separation system within an automated process. In a mass finishing system, work pieces must be safely separated from the grinding or polishing media. Media carry-out with the work pieces could result in disaster for subsequent assembly or machining operations and must be prevented. Methods of separation include screen separation and magnetic separation. This Rosler rotary vibrator features screen separation. Magnetic separation is also available on Rosler machines. While undersized media may not travel outside the machine with a work piece, these pieces must be removed within an automated system. Maintaining an optimum operating mix of new (large) and worn (small) media is just as important as separation. This requires that worn media is removed once it has reached a certain size and is no longer effective. If these smaller pieces are not removed, processing results will deteriorate and the process itself will eventually fail. In some instances, worn media must be removed from the process to prevent lodging. Undersized media screens are the most common way to remove media past its efficiency by allowing only small pieces to exit the mix, retaining larger pieces for further use without human intervention. Maintaining an optimum media operating mix of larger and smaller media requires that worn undersized media is regularly removed from the system. Undersized media screens allow media that is too small to be effective any longer to fall through screen holes and remove it from the media mix. Rosler has the answers.

Innovative Vibratory System Offers Precision Finishing of Delicate Work Pieces

Innovation is at the heart of engineering. At Rosler Metal Finishing , our engineers are constantly finding a better way to help our customers meet their surface finishing needs. That’s why they developed the R 150 DL-2 rotary vibrator . In addition to uses in the aerospace , automotive , tool and die making , electrical engineering, and equipment manufacturing industries, the R 150 DL-2 has proven its worth in the medical industry as well. In fact, this machine helped Waldemar Link GmbH & Co KG (LINK®) process its endoprosthetic components. The R 150 DL-2 was an excellent choice for LINK’s new “bi-mobil” hip implant. The implant offers patients a higher degree of mobility by inserting a movable PE joint in the acetabular cup. The PE-joint in turn is clamped to the ball of the hip stem. To minimize friction and prevent premature wear, the inside of the cup requires an extremely smooth surface, which can only be achieved with a high gloss polished finish—something the R 150 DL-2 easily achieves where other surface finishing companies failed. The perfectly smooth, polished inside of the acetabular cup minimizes friction and prevents premature wear. Unmatched Expertise LINK was searching for a mechanical method to achieve ambitious results in the concave surface area of the cup. The finishing task was especially challenging because of the relatively large depth and small diameter of the acetabular cups. Carsten Schöttler, production manager at LINK, explained why they chose to work with Rosler and selected the R 150 DL-2. “I contacted three equipment manufacturers, and only Rosler was able to achieve the surface finishes we needed,” he said. “Right from the beginning the Rosler sales and process engineers understood exactly what we needed. This made the cooperation not only easy, but actually very enjoyable.” Customer-Driven Results In its test center, Rosler developed a two-stage process with two machines. After machining, the work pieces undergo a wet surface grinding and smoothing step in the first machine. At the end of the cycle, approximately half of the processing media is removed from the work bowl. Then the fixture with the mounted work pieces is removed and bolted into the work bowl of the second machine where the work pieces receive their final high gloss polish in a dry process with special polishing media. With the increasing demand for improved surface finishes on high-value precision components such as LINK’s acetabular cups and more, the R 150 DL-2 provides an economical and repeatable option for surface finishing. The surface grinding and smoothing or high gloss polishing of internal surface areas once posed a significant challenge, but with surface finishing technologies from Rosler, batch-by-batch consistency for high-value, delicate parts can be achieved.

Automation, Part 3 — What Problems Do You Want to Solve?

We’ve all heard the saying “If it’s not broken, don’t fix it.” At Rosler Metal Finishing , we often view automation as the solution—or fix, if you will—for mass finishing and shot blasting processes in need of added efficiency. Previous posts in our Automation Blog Series focused on how robots improve finishing processes and why automation is beneficial to your business . We now turn our focus to an organization’s potential motivation for considering automation with the question, “What problems do you want to solve?” Both mass finishing and shot blasting are specialized processes that require a lot of practical consideration. Automating these processes can deliver great benefits to a manufacturer when properly targeted to a prescribed need, but, if the engineers developing the machine don’t understand your challenges, the solution is likely to miss its mark. Rosler Surf Finisher 1800 with robot handling Common Issues Evolving from an automated concept to reality requires a substantial amount of exploration and planning. Before the first machine is ordered, a company must have developed a surface treatment process that fully meets its targets for the desired finishing outcome and communicate what the specific problems are for successful automation integration. Viewing these issues as challenges, the experts at Rosler compiled a list of common issues that we have provided automated solutions for, including: Inadequate finishing quality – The achieved finish ( surface smoothing/polishing , surface preparation for painting, meeting required Almen values of a shot peening process , etc.) is not good enough and must be improved. Inconsistent finishing results – The required finishes cannot be achieved in a consistent, repeatable manner. Costs are too high – The achieved finishes may be acceptable, but processing costs are not competitive. Poor operational flexibility – The current process is too rigid and does not allow for quick reaction to changing demand patterns resulting in long lead times. Not enough qualified labor – It has become increasingly difficult to find people who are trained and willing to do mechanical grinding and polishing or even more basic tasks like material handling. Evaluating Your Process Once you know what problem your finishing process is experiencing, it’s time to step through the entire process in order to identify places for automation and other solutions. The first considerations are the work piece itself, desired surface finish, and desired or required processing technique. Once you have all the requirements and goals for these areas, determining whether the work pieces can be processed continually or in batches must be made. Deciding whether the work pieces are sturdy enough to come into contact with one another during processing or if part-on-part contact is prohibited must also be determined. Machine selection is the next step. Based on the specific type of machine chosen, consumables must also be selected. Relevant consumables may include compounds and ceramic , plastic , polishing and drying , and shot blasting media . Once these process factors have been evaluated, the surface treatment process can be properly defined. That’s when the advantages of automation can be realized, including: Consistent, repeatable process results. Cost savings. Improved operational flexibility. Overcoming labor shortages.

Part-on-Part Mass Finishing, Part 3 – Effective Finishing for Ammunition Work Pieces

The gun ammunition manufacturing process requires numerous finishing operations. Since ammunition parts allow for part-on-part mass finishing , Rosler Metal Finishing’s washing and drying machines are ideally suited for ammunition manufacturers. Available as rotary vibrators and centrifugal disk finishing systems, Rosler’s part-on-part finishing machines can accommodate various ammunition pieces including blanks, cups, deep-drawn casings, cartridge primers, and bullets. While the manufacturing step and finishing operation of each component varies by work piece and desired result, common mass finishing operations for ammunition based on the specific work pieces are summarized below. Cups Cups Created by running a brass coil through a cupping press, these work pieces require annealing. Cups are occasionally made from a blank as well. After slow cooling to reduce ductility, cups must be cleaned, rinsed, pickled, and dried through finishing operations. Casings A number of manufacturing steps are required for casings. Finishing operations may be required in between and/or after each step. Deep-Drawn Casing Deep Drawing – This process requires three drawings and subsequent annealing. Between each drawing and annealing pass, the casings must be cleaned, washed, and dried. They must also be pickled, rinsed, brightened, and dried after each annealing pass. Casing with Pinch Trim Pinching Trim – After trimming raw casings, work pieces must be cleaned, washed, and dried. Casing with Primer Pocket Forming Primer Pockets – Once the primer pocket is formed, casings must be cleaned, washed, and dried. Casing with Extracting Rim Extracting Rims – After forming the extraction of the casing rim, work pieces are annealed and in need of pickling, rinsing, brightening, and drying. Tapered Neck Casing Tapering Necks – Much like deep drawing cups, tapering the neck of a casing requires three passes. After the final pass, casings must be cleaned, washed, and dried. Casing with Mouth and Neck Tapering Mouth and Neck Toughening – After annealing the mouth and neck of a casing, work pieces must be pickled, rinsed, brightened, and dried. Bullets and Primers Bullets Like casings, bullets and primers must undergo different finishing operations. These operations primarily include cleaning and brightening and are required before each can be installed in the cartridge. Primers For these operations, centrifugal disk finishing machines are frequently used. Cartridges Cartridges After individual manufacturing and finishing steps, ammunition components are assembled into a cartridge. These assembled workpieces must undergo an oiling and polishing operation prior to packaging and shipping. Centrifugal disk machines are most frequently used to oil and polish assembled cartridges. The Rosler Way Several necessary yet unseen finishing steps go into the ammunitions manufacturing process. When dealing with small pieces in bulk, the capabilities of Rosler’s WTA machines offer a great way to streamline finishing processes in a single machine.

Automotive Crankshafts, Part 3 – Typical Mass Finishing Machines Used for Crankshafts

Crankshafts are an integral automotive component. Utilized to convert piston movement into rotational motion, these work pieces must provide reliable stability and withstand tensile, compressive, and shear stresses. Rosler Metal Finishing has extensive experience finishing crankshafts and other automotive work pieces with specially designed shot blasting and mass finishing equipment. Let’s take a closer look at mass finishing machines offering outstanding processing for crankshafts. Typical Machines Built with specific work pieces in mind, Rosler designs several machines to process crankshafts and other automotive work pieces. Due to their considerable size and weight, the only mass finishing machines capable of handling the deburring of crankshafts after machining are mid- to large-sized tub vibrators or linear, continuous flow vibrators. Selecting one machine type over the other largely depends on the work piece’s size. Tub Vibrators These machines are ideal for processing a wide range of crankshafts, from light-weight small work pieces to those weighing more than 500 lbs, with lengths of up to 20 ft (6,100 mm) or diagonal cross sections of 3.3 ft (1,000 mm). Rosler Tub Vibrator Because of the size of the work pieces they accommodate, tub vibrators require time consuming and costly manual loading and unloading of the work pieces. That is why their use is limited to relatively low production volumes. Linear, Continuous Flow Vibrators For high-volume production, fully or partially automated linear, continuous flow vibrators are the ideal solution. These machines can handle large volumes of crankshafts with lengths of approximately 12 to 30 ft. The use of robots or handling devices like gantry systems for loading and unloading allows fully automatic operation. Rosler DA Linear Continuous Flow Vibrator DA linear, continuous flow vibrators can handle the deburring of small- to mid-sized crankshafts at cycle times of less than one minute per part, more than 60 parts/hour. They can be directly linked to the preceding machining operation and the subsequent washing process. The Rosler Way Rosler has more than 80 years of experience in surface finishing.
