_ Finishing processes
Precision finishing
More and more demanding quality standards on the market are dramatically increasing the importance of precision surface finishing processes. These treatments improve the aesthetic appearance of metal parts, but also their mechanical and physical characteristics, corrosion resistance and lifespan, among others.

Smoothing
Processes related to smoothing metal surface allow to achieve uniformity of product for appearance’s sake, and to be safe for touching without being scratched to shreds by unfinished roughness. For moving parts, a smooth finish cuts down on friction loss, without getting into coatings.

Mirror finishing
A mirror finish is a highly-polished finish, characterized by a bright, shiny, reflective metal surface. A high-quality mirror finish is not only visually appealing, but the gradual removal of surface scratches reduces indentations or grooves on metal, which may contain contaminants, such as dirt or bacteria.

Deburring
Deburring is a material modification process that increases the final quality of the product by removing impurities with a negative impact the on the appearance of a smooth machined surface, like sharp edges or burrs, left by bending, cutting, piercing, shearing and compressing materials.

Rounding
Rounding cutting edges is crucial for the design and geometry of cutting tools in metal machining. Cutting edge geometry determines the thermo-mechanical stresses on the tool. By employing edge preparation, tool life, cutting performance, and the quality of the machined surface can be improved.

Corrosion resistance

AM Post-processing
Surface roughness of AM parts can vary depending on the technology used and parameters applied, and affects fatigue, corrosion resistance and friction properties. In order to improve the surface quality, electropolishing is postulated as the most promising the treatment to reduce roughness and defects.

Inner channels
Surface quality requirements of internal surfaces, inner channels and complex parts with blind holes have increased during the last years specially in case of injection molding, aerospace, automotive, medical, food and pharma, semiconductors and gas and fluid flow applications.

_ Industries
Aerospace
Surface finishing operations play an extremely important role in aerospace and energy sectors, since it helps to improve efficiency, while increasing reliability and durability. These parts must withstand high stress corrosive conditions, high loads with long-term lifespan and meeting demanding cycle life specifications.

Automotive
Surface finishing solutions are utilized at every level of the automotive pipeline, from garage maintenance and car restoration to manufacturers’ demands. One of the most challenging aspects has to do with safety, since the result of the surface finishing process is closely linked to the vehicle performance and reliability.

Dentistry
Dental laboratories use dry electropolishing to improve surface quality of cobalt-chrome and titanium dental parts. Smoothing, cleaning and eliminating small imperfections from removal dental prosthetics and other implanted dental parts expands their lifespan pieces and can extend the life of dental components from the inside out.

Food & Pharma
Metal components produced for food, beverages, packaging and pharma industries must comply with challenging surface finishing standards. Those surfaces should be ultra-smooth, precision finishing, thus avoiding areas for bacteria grow. DLyte achieves superior results than any other surface finishing method.

Jewelry & Fashion
These industries require a perfect surface quality as the purpose of the piece is mainly aesthetic and its value depends on a good looking. Complex geometries in jewels are hard to polish with traditional polishing methods and electropolishing is one of the techniques utilized for a better homogeneity and standardization.

Medical device
Cleanability, biocompatibility, corrosion resistance, pathogen resistance and a smooth surface without defects are crucial to comply with the function and demand on quality of the medical industries. Improving the surface’s quality on implants, instruments and equipment components increases functionalities as well as their lifespan.

Toolmaking
Overcoming the drawbacks of tool finishing is one of the main challenges in the field of surface finishing solutions, in order to achieve the lowest roughness on flat surfaces. This is why DLyte has specially created new electropolishing technologies to carry out the most challenging freeform surfaces polishing.

Cutting tools
DryLyte offers an innovative solution for precision surface finishing on cutting tools, delivering consistent, repeatable results with mirror-like finishes. Its unique dry electropolishing technology preserves tool geometry while enhancing surface quality. By reducing friction and wear, DryLyte extends the lifespan of polished parts—making it ideal for high-performance industrial applications.

_ Technology
Immersion
DryLyte is a patented technology for grinding and polishing metals by ion transport using free solid bodies. It works by combining the electrical flow created by high-precision rectifier. This results in an ion exchange, removing material from the peaks of roughness.
Projection
Our new Electro-Blasting technology, released in 2021, is a new solution that provides a stream of solid-electrolyte particles propelled by a non-conductive liquid media to improve the surface quality. The media is projected towards a localized area of the piece.

Rösler Oberflächentechnik GmbH and GPAINNOVA are expanding their partnership: After Rösler has been the exclusive distributor of GPAINNOVA’s DLyte Industrial Series for the German market for some time now, the world market leader Rösler will also take over the worldwide distribution of GPAINNOVA’s Carbide Cutting Tools Series as well as the individual process development and service of the machines. In addition, GPAINNOVA is working closely with Rösler on the further development of the DLyte Carbide Series and the underlying DryLyte process.
A new standard for carbide cutting tools
The carbide machines use the patented DryLyte technology for surface finishing cemented carbides and are intended to replace drag finishing as the standard process for carbide cutting tool finishing, resulting in even more efficient and better tools. By expanding its partnership with GPAINNOVA, Rösler is making further inroads into the tool making industry, one of the company’s new focus markets. “We at the Rösler Group are delighted to be able to expand our portfolio in the field of cutting edge preparation with such an advanced and promising technology. We are convinced that DLyte is clearly superior to drag finishing in terms of quality, cycle time, handling and cost-effectiveness. This technology will be able to replace the conventional drag finishing systems up to a large scale as the most commonly used process in cutting edge preparation, and that it will quickly establish itself in the market,” says Alexander Fitz, Head of Sales Mass Finishing at Rösler.
The DryLyte technology, also known as dry electropolishing, is much gentler than drag finishing and produces a much more homogeneous surface finish. Unlike traditional methods, the DryLyte technology works much more gently and without a mechanically abrasive procedure. This offers to the companies a new technology that removes material through ion exchange to produce a homogeneous radius preparation and smooth surface. “The process is the future of cutting-edge preparation,” says Fitz. “The technological development behind it is outstanding. We are absolutely convinced that we can offer our customers a technological advantage with this extended partnership”, he adds.
The Spanish technology company is confident in the collaboration with world market leader Rösler: ” The agreement between GPAINNOVA and a world leader like Rösler marks a significant milestone for both entities; by pooling our expertise in the realm of surface finishing, particularly in the treatment of carbide cutting tools, we aim to deliver unparalleled benefits to our customers,” evaluates Pau Sarsanedas, CEO, and co-founder of GPAINNOVA. ” This strategic alliance not only expands our market reach but also equips us to empower a broader spectrum of clients, enabling them to harness the collective knowledge and capabilities of our organizations and unlocking a wealth of opportunities for innovation and growth,” Sarsanedas concludes.
Over the coming months, Rösler is looking forward to numerous trade fair appearances, processing trials and collaborations with companies from the carbide cutting tool industry. “We will convince our customers that the innovative DryLyte technology is up to the daily demands of the challenging industrial environment and can massively increase the product quality of carbide tools,” assesses Fitz.”
