Open the catalog to page 1Achieves both strength and Features of Epoch CBN Super Ball End Mil Cutting resistance is low, so the finishing surface is excellent and finish accuracy is higher. Fine (F) type: Prioritizes high-accuracy machining Strong (S) type: Prioritizes stable machining Two types of geometry are available for sharpness of cutting edge and rigidity, enabling the geometry type to be selected according to the machining application.
Open the catalog to page 2EPOCH CBN End Mill series Features of Epoch CBN Super Radius End Mill PAT.P Radial rake is positive. (Sharpness of cutting edge priority) Axial rake is negative. (Rigidity priority) Durable CBN material Reliable compound neck shape Differences in cutting characteristics for ball end mill and radius end mill When bottom cutting Cutting is performed near tool axis, so there are few outside vibrations. Vibrations are more likely to occur with radius end mills. When cutting, vibrations tend to become stronger at the outside. Because of this, with a radius end mill, even if priority is just...

Double Face Shape Double Face Effect R cutting edge improves sharpness of cutting edge while flank surface consists of 2 surfaces to ensure rigidity. First step increases rigidity. F type and S type both ensure Face sharpness of cutting edge while rigidity of flank surface is improved. Cutting resistance easily occurs at cutting edge and sharpness of cutting edge is poor. When cutting resistance rises up easily, it affects the finish...

Comparison of cutting depth I Cutting Condition S type has a high cutting depth limit, enabling stable machining.
Open the catalog to page 5Recently, the trend in mold has been toward harder and harder materials, and cutting such materials has become very difficult. In addition, in order to respond to demands for ultra-high precision, tool wear resistance has become very important, and recently tool materials other than carbide, such as CBN, etc., are receiving a lot of attention. The geometry of this newly developed Epoch CBN End Mill series, unlike the conventional geometry commonly seen on most CBN tools which focuses on rigidity, achieves both rigidity and good sharpness of cutting edge. In this way, it enables...
