The in-house development of CBN end mills by Towa USA, featuring high precision and sharpness, optimal abrasion resistance and a long lifespan, began in response to an internal requirement for ultra-precision mold processing.
Towa says its goal was to further maximize machining output capabilities with respect to high hardness materials used for semiconductor mold chases and specifications required by customers, related to precision and durability.
The company’s CBN end mills can be re-ground, enabling a reduction in the unit cost of the cutting tool. CBN “Lapping” end mills, for instance, achieve mirror-like finishes with a more consistent surface, reducing time spent hand polishing molds. Towa’s Bancera ceramic coating, applied to the CBN, adds high heat resistance and further extends the tool’s life. In addition, Towa is able to assist customers in selecting appropriate cutting tool types for application uses, such as parts process and processing approaches.
In addition to a standard line-up, Towa is able to develop custom-made items such as tool diameters and corner configurations per the customer’s request.
