3 Epoch Super Hard Ball EPSB-TH No Recently, harder and harder materials are being used in mold processing, making machining extremely difficult. In addition, tool durability against wear is very important for ultra-high-accuracy processing, and CBN tools, etc. have been gaining focus in addition to carbide tools. However, there are many problems such as chipping, so that currently stable processing cannot be performed. The newly developed Epoch Super Hard Ball uses a new flute shape and new carbide material to push the limits of our original TH coating to provide wear durability approaching that of CBN tools. Features & Applications RR R R RR New flute shape provides a huge reduction in wear compared to conventional products. Use of backdraft shape suppresses the vibrating chatter peculiar to small-diameter tools to enable stable machining. Guaranteed ultra-high and shank accuracy enable ultra-fine finishing. Select the desired : High-accuracy rating product : mmR+0.001mm Standard rating product: mmR+0.003mm Wear durability approaching that of CBN tools provides long tool life even when directly machining materials with hardnesses exceeding 60HRC. Dimensional sizes of R0.05 to R1 make them ideal for machining of small parts. This is the point! Processing standards are measured at the tool tip. Therefore: R When machining, the tip of the flute edge becomes the standard. It is therefore important to guarantee the of the tip standard. Epoch Super Hard Ball provides guaranteed high accuracy of the tip standard. A nano composite coating material realised extraordinary heat resistance and hardness because of its composite layers consist of Nano Crystal material 3
