CARBIDE END MILLS TECHNOLOGY DATAS

CARBIDE END MILLS TECHNOLOGY DATAS

1. Main difference of end mills made of good tungsten carbide and common tungsten carbide (different material and the same manufacturing process)They have similar performance on hardness, toughness and the difference is on the wear resistance, which mostly decides the life of the end mill.End mills made of common tungsten carbide only apply for cast iron, carbon steel, low alloy steel, copper alloy. These materials have low tensile strength (under 1000Mpa) and low hardness (under 30HRC). For stainless steel, high alloy steel, prehardended steel, hardened steel (high hardness or high tensile strength),  these end mills have inferior performance and even can't work on these materials. Usually the life of end mills made of tungsten carbide is about 30% shorter than that of end mills made of good tungsten carbide when milling  low tensile strengh materials or low harden materials.
