End mill cutter material

Climb helps prevent the use of drill bits for metal, can improve cutter life. But there are two points to note: ① as ordinary machining, should seek to eliminate the gap feed mechanism; ② When the workpiece surface residual casting, forging process to form an oxide film or other hardened layer, should adopt the milling.
The use of high-speed steel end mills require a more broad scope and use, even if slightly inappropriate choice of cutting conditions, not to be too much problem. The carbide end mills, while having good wear resistance at high cutting, but it's not as extensive use of high-speed steel end mill cutter and cutting conditions must be in strict conformity with the requirements of the cutter.
