Tungsten Carbide Staggered-edge End Mill (1/2)

Tungsten carbide staggered-edge end mill is usually composed of tungsten carbide (WC) + cobalt (Co) and other additives by compacting and sintering. Tungsten carbide mills has broad scope of application, such as CNC machining, engraving and some ordinary milling machining for hard material with simple shape of heat-treated material. According to the shape of edge, it can be specifically divided into integrated tungsten carbide mills, tungsten carbide cylindrical mills, tungsten carbide facing mills, tungsten carbide shank-groove mills, tungsten carbide helical mills, tungsten carbide staggered-edge end mills, tungsten carbide side cutter, tungsten carbide end mills, tungsten carbide saw blade mills, tungsten carbide angled mills and so on.

Generally, tungsten carbide staggered-edge end mill used for stepped surface machining grooves and other parts. The edge located in the circle and surface, which can not be fed in the axial direction only when the legislation is available on the cutter and the axial center of the edge through the end of the feed. This makes the milling edge design focus shifted to how to reduce the axial thrust generated by the tool in the cutting process in case of restraining layer, tear and burrs. Viewed from the direction of feeding and rotating of tungsten carbide mills for the workpiece, it mainly includes two kinds, one is up milling, the other is down milling. The so-called up milling means that the feed direction of the rotational direction of the cutter and cutting the same at the beginning of the milling cutter on the workpiece until the last; while the opposite direction of feed milling cutter rotation and the cutting, before beginning the milling cutter must be some slippage on the workpiece, cutting thickness from scratch when cutting until the end of the maximum thickness.
