Form Grinding of Magnets for Motors / High Precision Electroplated Wheel FORMASTER
High Efficiency and High Precision Form Grinding This is a high precision electroplated wheel realized by our original precision electrodeposition technology and shows excellent shape retention performance and long-lasting sharpness in form grinding. Since truing / dressing on a machine is not required, high precision and high efficiency form grinding is possible. ・Reduced grinding force: Long-lasting sharpness ensured by "precision electrodeposition technology." ・Long life: Improves tool life by suppressing changes in the shape of edges and recesses ■Features ・Form machining of motor magnetic material (Air conditioners, EPS, Power windows, HV drive motors) ■Applications
New Generation Automotive (xEV) For Machining Aluminum Parts / PCD Rotating Tool with Regrindable 3D Chipbreaker "Regslash"
・3D chipbreaker for chip braking and improving downtime ・Regenerates the effect of chip breaking, reduces tooling costs and shortens cycle time ■Features Chipbreaking and Energy Cost Reduction in Aluminum Parts Machining This tool solves the problems of conventional 3D chipbreakers by newly-developed regrindable 3D chipbreaker. It improves downtime due to chip problems and reduces energy costs by controlling tool costs, etc.

For Machining Aluminum Parts / High Feed PCD Reamer
・Our original "3, 4, and 5 flute unequal flute spaced design.“ ・Enables higher precision machining than ever before under high feed conditions. ・Significant reduction in machining time (number of machines,operating time, and CO 2 emissions) for aluminum parts that require high precision machining can be expected. ■Features This new generation tool is expected to reduce machining time by several tens of seconds compared to conventional tools. (*) Realizes highly efficient machining while maintaining the quality of deep hole reamer finishing. Contributes to reduction of CO 2 emissions by shortening equipment operation time. (*Compared with Vc150 f0.15 φ12, depth 100 mm, 6-hole finishing)
