The Rosler portfolio of mass finishing machines ranges from simple rotary vibrator to fully automated surf finishers with robotic equipment. The conception and implementation of systems and processes which are individually designed for the customer are one of Rosler's core strengths. Metal, plastic, ceramic or wood...deburring, degreasing, descaling, rust removal or polishing: The options for the use of Rosler mass finishing machines are simply endless.
High Energy Disc Systems
Our high energy disc systems make mass finishing more efficient than ever before. Compared with conventional vibratory finishing, a 10- to 15-fold increase in performance can be achieved with the help of centrifugal force. High energy disc systems are inspiring not only because of their speed but also because of their processing spectrum. Among other things, they are used for deburring, grinding, rounding, or polishing stampings, castings, forgings, and machined work pieces – from thin-walled to solid. High energy disc systems are used in medical technology, jewelry and eyewear manufacturing, as well as in the automotive sector as well as in many other special applications. The operating principle of a high energy disc system is based on the interaction of the fixed, cylindrical work bowl (or tub) in combination with a spinner, which is separated from the tub wall. The spinner accelerates the work pieces and finishing media, and the centrifugal force generated in the process pushes the mixture of media and work pieces against the work bowl wall, where it continues to move upwards until it is finally returned downwards to the spinner by the force gravity and the cycle begins again. Our high energy disc systems feature an optimized work bowl design, an energy-efficient electric drive, and compact system control and process water supply. We have also revolutionized the market with a particularly economical two-batch system and an absolutely reliable and patented annular gap control and regulation system.
Process water recycling systems
Today, almost any mass finishing process can be linked to a Rösler process-water cleaning system. The process water is cleaned of the solids generated during mass finishing and can then be re-used in the finishing process. This makes the process much more sustainable and cost-effective. The basis of modern process-water cleaning technology relies on the principle of two-phase solid-liquid separation using centrifugal force. Depending on cleanliness requirements, particle sizes and materials, the systems can achieve throughput rates of up to 6,000 liters per hour. Thanks to the high acceleration of up to 2,000 g, particles larger than 2.0 µm are separated from the liquid and collected by the centrifuge rotor as a filter cake. By using our process-water cleaners, which have been specially developed for process water recycling, the physical separation performance of the centrifuge can be optimized. This ensures that the quality of the process fluid is maintained for the entire service life. Powerful installations – in connection with sophisticated process technology – enable a wide range of application, even beyond mass finishing applications.
Dryers
Almost all processing methods in vibratory grinding are wet processes. In order to be fed into the next production process, work pieces usually must be dried after mass finishing. We offer our customers sophisticated solutions that allow the drying process to follow the vibratory grinding process smoothly and automatically. Among the requirements placed on the systems are that they can be directly connected to the mass finishing system in terms of control technology and that they can be operated in an energy-efficient manner while maintaining high drying performance. We offer four different types of dryers. These process the finished parts continuously or in batches using a drying media depending on the type of system. They are also tailored to the specific requirements of the various industries. In accordance with our one-stop philosophy, the appropriate drying media is also part of our comprehensive portfolio.
Tub Vibrators
For the processing of particularly large-volume and/or heavy work pieces in the mass finishing process, Rösler trough vibrators have proven themselves time and again. These systems can be used for all common mass finishing processes – whether deburring, edge rounding, grinding, polishing, or ball burnishing. Tub vibrators are suitable for single part processing as well as for processing several components simultaneously. In the second case, the parts are either separated by dividers or, in the case of sensitive components,mounted on special fixtures. The mode of operation of all variants of Rösler trough vibrators is similar. Driven by vibratory drives adapted to the size and type of system, the grinding or polishing media and the work pieces filled in the working space are set into a roller-shaped, vibrating rotary motion. This type of system is used in numerous sectors such as the aerospace and automotive industries as well as in general mechanical engineering.
Continous flow mass finishing installations
If mass finishing needs to integrated into a continuous process, through-feed systems are a logival choice. Through-feed systems are ideally suited for the fully automatic vibratory finishing of stampings, castings, forgings, or machined work pieces. Deburring, grinding, rounding, and ball burnishing are the most common processing methods for through-feed systems. There is a choice of through-feed systems in linear form and in the Rotomatic variant, a special development of Rösler. The numerous special features of our Rösler through-feed systems are continually opening up new fields of application. The sophisticated machine design, conceived for continuous industrial operation under demanding conditions, various work bowl sizes, the robust drive technology, a large-area separating station, and the modern control technology ensure maximum reliability – even under the harshest of operating conditions. No other supplier can offer a more diverse and wider range of through-feed systems.
Unlimited applications - no matter what your requirements are
Our shot blasting machines offer you almost unlimited options for surface finishing: from deburring, descaling, de-sanding and rust removal to roughening, cosmetic blasting, smoothing and edge rounding all the way to shot peening. After all, the functionality and aesthetics of surfaces are not only an important sign of quality for technical products, they also contribute significantly to their success on the market. Surface finishing is therefore nearly always essential and has to be integrated into existing production processes as an additional, value-added step. Not many technical procedures have such a variety of uses as shot blasting, especially when it comes to metal surfaces. However, other materials, such as concrete, sandstone, glass, textiles, wood and plastics, can also be processed with machines from Rösler.
Shot blasting machines for steel profiles, structures and steel sheets
Roller conveyor blast machines are suitable for the descaling, paint stripping, rust removal, roughening, and cleaning of work pieces such as sheet metal plates, profiles, beams, and pipes. Depending on the type of system, thin sheet metal plates up to massive steel profiles weighing several tons can be processed. The largest systems allow optimal processing of work pieces up to 6,000 mm in height and up to 5,000 mm in width. During processing, the work pieces pass through the pre-chamber, blast cabin, and post-chamber of the system – either one after the other or in batches on a roller conveyor. Depending on the type of system, shot blasting is carried out with precisely positioned blast turbines equipped with energy-saving motors. The blasting result is all-round, comprehensive, and always reproducible. Roller conveyor blast machines can be easily integrated into existing production lines. Despite their sometimes considerable size, the systems are easy to maintain because the components can be conveniently reached through large access openings and inspection platforms.
Tumble belt blast machines
Tumble belt blast machine are suitable for the derusting, deburring, roughening, or cleaning of robust work pieces of any size that are suitable for tumbling. Depending on the type of system, the work pieces are processed in either batches or in continuous operation. The use of a tumble belt blast machine is also ideal for shot peening, matting, or general surface finishing. When it comes to the material of the work pieces, the spectrum ranges from small plastic parts to massive, sand castings depending on the system design, Depending on the system type, the machines are used for blasting transmission parts, forged parts, and light metal components. In the blasting area, the work pieces are constantly in motion. Through the perforated tumble belt, which is made of rubber as standard (but optionally also of steel), the parts are circulated and simultaneously blasted with the aid of up to three high-performance turbines or with compressed air. Typically, up to four turbines are installed in continuous feed tumble belt blast machine. For everyday foundry use, the systems can also be lined with manganese steel plates. This ensures both a longer service life and lower maintenance requirements.
Post processing of 3D printed components
For post processing of 3D printed components — removal of powder and support structures, surface smoothing, surface homogenization and polishing — post processing solutions from AM Solutions cannot only offer a wide variety of suitable consumables, but also a broad range of equipment, either made in-house or supplied by competent partner companies. Our solutions, suitable for different printing technologies and materials, guarantee outstanding quality, a high degree of result repeatability, and excellent cost efficiency. Our machines cannot only be utilized as stand-alone systems, but as completely linked installations they can also be easily integrated into your existing manufacturing line. Besides providing you with all kinds of equipment options, we can also assist you with your part design to ensure that the post processing of your products can be achieved in a sustainable and cost-efficient manner.
"Mobile" Tub vibrator
Rösler “mobile” Tub vibrators, model range RMO, with built-in separation unit can be easily integrated into manufacturing lines. This machine type, equipped with process water recycling tank, is ideal for any wet mass finishing processes. The RMO allows cost efficient surface finishing in stand-alone operation, directly in the manufacturing line.
Gamma G turbine for shot blasting machines
The key component in RÖSLER shot blasting machines is the Gamma G turbine. Its material quality and special design provide, compared to conventional turbines: - Up to 16 times higher wear resistance. - A reduction in energy consumption of at least 10 to 25%. - Shorter cycle times thanks to up to 77% higher impact energy. All this translates into: - Lower maintenance costs. - Reduced energy costs. - Increased productivity. And this is thanks to: - Being manufactured in forged tool steel. - The specific curvature of the blades, which provides a higher blasting speed, increasing its kinetic energy. - The double-sided design of the blades, in a “Y” shape, which allows them to be used on both sides. - The opening of the upper cover of the turbine casing and the anchoring system of the blades, which allows them to be rotated or replaced without having to remove the turbine from its housing. However, it is not always necessary to purchase a new blasting machine to benefit from these advantages. Often there is a more sustainable and economical solution: retrofitting and upgrading the existing shot blasting machine. Rösler has a qualified and experienced team that will check your shot blasting machine, advise you on the work to be done on it and offer you the best technical solution to get the best out of it.
