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.
Recently, 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 high-precision finishing machining over a long period of time on high-hardness materials.
Features and Applications
❶ Can be used as easily as carbide end mills while reducing wear.
❷ Cutting edge shape takes care of chipping, which is a problem with CBN materials, enabling stable finishing for a long time.
❸ Biting characteristics are the same as those of carbide end mill but cutting resistance is reduced, so finish accuracy is improved.
❹ Long life even when direct cutting high hardness materials of 60HRC or higher.
❺ Ideal for small-work machining, with a lineup of ball end mills in sizes from RE0.1 to RE1mm and radius end mills in sizes from φ0.5 to φ3mm. (Under neck length: up to 10DC)
