Union Tool receives Technical Achievement Award

Union Tool Co., Tokyo, has been recognized by the Japan Cemented Carbide Tool Manufacturers Association for Technical Achievement and Services to Industry. The award was for the development and implementation of the UDC diamond coating of carbide endmills that has established the ability for an endmill to “cut” cemented carbide using a direct milling strategy.

U.S. Union Tool Inc., Anaheim, Calif., introduced this product to the North American market at IMTS in September and has received inquiries on the UDCB series ball endmill that features this coating.

Key to the UDC coating’s success has been the ultrahard surface that is close in hardness to single-crystal diamond (approx 9,000Hv), combined with a preparatory treatment that ensures the coating resists peeling from the endmill during use. The coating has been awarded a patent.

These factors, together with the specific geometry of the cutting tool, enable users to adopt a direct milling strategy, from CAM design, rather than using grinding or EDMing. The new approach improves time to market and reduces cost, according to Union Tool.

The range of UDC coated tools will soon be expanded to include other endmill styles and lengths, consolidating the current UDCB ball endmill series that offers a diameter range of 2.0mm to 6.00mm.
