Dry electropolishing equipment for superior high-performance finishing applications in the toolmaking industry
The quality of milled, formed, and punched parts hinges on the tools used in manufacturing. Processes like surface smoothing, coating, polishing, burr removal, controlled rounding, radiusing, and corrosion protection significantly extend the lifespan of drills, milling cutters, thread rods, stamping tools, forming dies, and holders. This ensures a consistent and reliable quality of final parts, enhancing performance and longevity.
Due to the limitations of current automated polishing techniques, particularly on pieces with freeform surfaces and functionally critical edges, the processes of smoothing, rounding, radiusing, and deburring are primarily carried out manually or through intricate multi-step procedures. These methods tend to be error-prone and resource-intensive.
DLyte automates edge honing, polishing, smoothing, coating removal, and decoating, enhancing tool performance and lifespan while ensuring precision, mechanical integrity, surface uniformity, and wear reduction. This advanced solution replaces expensive diamond wheel and robotic systems, reducing roughness in flute areas and controlling cutting edge radius to deliver consistent and precise results in an ultra-fast process.

Benefits of DryLyte Technology in Toolmaking
Dry electropolishing technology is a novel electrochemical process specially recommended to improve life of cutting tools through rounding of cutting edges and improvement of flute surface. Since dry electropolishing is not a mechanical process, the material hardness has no bearing on the material removal rate. In addition, it is also suitable for annealed, hardened metal parts and other materials as carbides.
The DryLyte Technology used in the dry electropolishing machinery DLyte, is a patented surface finishing technology by ion transport using free solid bodies. In DryLyte the liquid acids are replaced with a set of tiny solid spheres of a non-conductive polymeric material capable of retaining liquid electrolyte and conducting electricity while removing the oxides produced during the electropolishing process.
It works by combining the electrical flow created by a high-precision rectifier with the movement of the pieces through the dry media. This results in an ion exchange and removal of material only from the peaks of roughness. The process performs controlled rounding and can access corners that are not easily accessed mechanically.

Improve carbide surfaces with controlled leaching
Cemented carbide, the predominant material in the toolmaking industry, contributes significantly in enhancing precision and surface quality due to its superior hardness, durability, and wear resistance.
However, due to its composition of small tungsten carbide particles suspended in a metallic matrix, surface finish with state-of-the-art processes can be extremely difficult.
DLyte technology offers a plethora of advantages by maintaining the superficial chemistry unaltered, it ensures that the original properties of the material are preserved. Additionally, DryLyte Technology prevents any leaching effects on the metallic binder, which contributes to the overall stability and durability of the treated surface. The process achieves an impressive roughness between constitutive phases of below 9 nm, resulting in a smooth and consistent surface finish.
The system also allows for precise electrical parameter adjustments to achieve controlled leaching, resulting in improved surfaces for subsequent coating.
Edge preparation with controlled radius
INCREASE OF RADIUS AROUND 1 μm/min
The minimum and controlled rounding effects further enhance the final surface quality, ensuring uniformity and reduced wear. Moreover, the mechanical integrity of DLyte is an effective automated process to round cutting edges of end mills, carbide inserts and carbide reamers to specific radius according to the manufacturer requirements and improve at the same time the surface quality of the flute thus allowing a faster chip flow and increased chip volume.
The dry electropolishing technology improves the result of current technologies. It overcomes the barriers of abrasive polishing using solid particles to remove material by ion exchange, even in very hard materials as carbide. As it is a non-abrasive treatment it maintains a good balance between smoothness of the flute and edge radius increasing tool life and resulting in less tool wear.
