Milling cutter

A milling cutter is composed of a cutter handle and a cutter head, the cutter head is arranged at one end of the cutter handle, the cutter handle is made of tungsten steel materials, the cutter head is made of zirconium oxide ceramic materials, and the cutter handle and the cutter head are mutually combined to form the complete milling cutter. By means of the structure, the defects that a traditional milling cutter completely made of tungsten steel is not enough in strength and not high in machining precision can be effectively overcome, the strength of the whole cutter is well enhanced through the material mode that the tungsten steel and zirconium oxide ceramic are combined, deformation is avoided in the using process, and the machining precision is high; besides, the milling cutter headis directly prepared from zirconia ceramic, the cutter head is high in hardness and more wear-resistant, and a coating does not need to be additionally coated, so that pollution caused by chemical plating is avoided, and the
