What are industrial surface finishing technologies?

Surface finishing, surface treatment and surface refinement of components to optimize their functionality: The surface condition of components (work pieces) produced at high volumes on an industrial level generally does not satisfy the needs of the end-users. Therefore, to comply with the end-user demands, these components must frequently undergo various surface refinement operations. This is achieved with different types of surface finishing or surface treatment technologies. Their goal is to make the component surface more resistant against premature wear for a longer service life, to make the surface esthetically more pleasing, or to make it more functional by, for example, improving its anti-friction characteristics and protecting it against premature corrosion. The goals are achieved by precisely defined surface treatment methods irrespective of how complex the shape of a component might be. In this respect it is essential that the chosen treatment method can reliably and consistently achieve the specified finishes. Moreover, the surface finishing results must not exceed the specified dimensional tolerances, so that the component geometry remains intact. The term surface treatment or surface finishing includes all surface refinement technologies used in a high-volume industrial production environment.

Shot blasting, deslagging and deburring in combination - for perfect surfaces in heavy industry

In the world of metalworking, achieving the highest quality finish on parts and components is essential for both aesthetics and functionality. This is particularly true in industries that process thicker parts and heavy plate like the manufacturing of construction equipment, railcar, shipbuilding, etc. to name a few. Especially for those industries, precision and durability are paramount. To meet these stringent requirements, manufacturers often rely on a combination of advanced surface treatment solutions. Among these, shot blasting, deslagging, and deburring machines play crucial roles. This article will explore the importance of integrating shot blasting with deslagging and deburring machines to optimize production processes and enhance product quality.

Orthopedic Implants – Shot Blasting Improves Longevity and produces the most sophisticated surfaces | Part 3

Like mass finishing, shot blasting is an exceptionally versatile surface treatment technology. Its applications range from general cleaning after casting and forging to shot peening and, even, cosmetic blasting for placing a fine, matte finish on the work pieces. Shot blasting is an impact system in which small metal or mineral pellets are thrown onto the surface of a work piece at speeds of up to 140 m/s while using turbine basting systems. This would be way to rough for the treatment of sensitive parts from the medical technology sector. Compressed air blasting systems are mainly used for these applications, which are used both as a dry blasting variant and as a wet blasting variant. The smoothest finishes achieved with shot blasting are about Ra = 16-32 microinches (= 0.4 to 0.8 μm), with wet blasting we are able to achieve finishes below Ra 0,2 µm. The final finish highly depends on the preparation of a surface before blasting.

This innovative machine can simultaneously and fully automatically perform multiple surface treatment tasks such as cutting edge preparation, polishing or decoating work pieces. This is possible, because up to four different electrolytes can be used at the same time in the DLyte system. The machine was designed with the goal of easily integrating it into existing manufacturing lines. Please find out more about this groundbreaking improvement of the DryLyte technology for surface finishing of carbide components on the Rösler booth at the AMB trade fair taking place September 10 to 14 in Stuttgart (hall 5, booth 5C61).

Fully automatic shot peening of gear parts for E-vehicles

Shot peening has established itself in the automotive industry as an indispensable surface refinement operation. For this task a leading German automobile manufacturer integrated the indexing satellite table shot blast machine RST 200-S15 from Rösler into a new manufacturing line for gear components for E-vehicles. The customer decided to purchase the Rösler equipment, because he had excellent experience with machines of the same type regarding productivity, process stability and ease of maintenance. In the automotive industry shot peening is utilized to induce a compressive residual stress in, for example, gear components and, thus, extend the life span of the material. For this challenging task, the BMW plant in Dingolfing uses satellite table shot blast machines from Rösler, which have been precisely adapted to the customer’s technical requirements. Now, the highly adaptable RST 200-S15 equipment concept was implemented in a new manufacturing line producing gear components for E-vehicles.

Forge & Foundry, Part 4 – Selecting a Shot Blast Machine for Sand Castings

Building upon the information shared in our last Forge and Foundry Series post about sand casting, we now turn to the process of selecting and designing machines to specific sand casting operations. Selecting the right shot blasting machine for your process and work piece means understanding how the work pieces and machine will interact. Here are common questions Rösler receives when developing perfectly specified solutions for sand casting.

Rösler vertical shot blast machine for processing sheet steel

The blasting of large, pressure-sensitive sheet metal made of materials such as stainless steel is a special challenge in steel construction that sometimes requires a complete rethink. The solution can then be that sheets do not pass through the shot blasting system in a horizontal position but are blasted “standing up”. Vertical shot blast machines are then used. These pose very special challenges in terms of development and design, but also offer other advantages such as a more compact and shorter system design and the avoidance of abrasive accumulation and abrasive pressure on the sheet metal. Technically speaking, a vertical shot blast machine is simply a modified roller conveyor blast machine. An example of such a system - and the largest one built by Rösler to date - is the vertical shot blast machine for the Chinese steel producer TISCO.

Mirror finish for high-end forged wheels in less than 40 minutes

Forged aluminum wheels are not only characterized by their low weight, high stability and excellent load bearing characteristics but also by their exclusive optical appearance. Therefore, it is not surprising that manufacturers of luxury cars are primarily utilizing forged aluminum wheels in their vehicles. Optical highlights of the high-end automotive wheels are not only their attractive design but also their immaculate high gloss polish. To achieve such a perfect finish the wheels must undergo a surface grinding and smoothing operation before they can be polished. Treating the wheels with classical vibratory finishing methods or finishing them with costly manual labor requires several hours of processing time. A leading wheel manufacturer wanted to significantly reduce the time requirements for partially finishing already painted bicolor wheels and was looking for a suitable technical solution. This was found with the Rösler plunge finisher R 1/1 TSA-O/VS-So. The plunge finishing technology was developed by Rösler for the consistent and quick deburring, edge radiusing, surface grinding and polishing of complex, heavy and delicate components.
