Description

Tungsten steel end mill for enhancing knife tip protection Technical Field The utility model relates to the technical field of end milling cutters, in particular to a tungsten steel end milling cutter for enhancing cutter tip protection. Background Tungsten steel end mills are widely used in metal cutting operations, particularly in the processing of materials with relatively high hardness (e.g., steel, aluminum alloys, titanium alloys, etc.). However, the conventional tungsten end mill may still have problems of wear, tipping or insufficient damage resistance of the tip during use, and thus it is required to develop a tungsten end mill with enhanced tip protection. The tungsten steel end mill with enhanced cutter tip protection can remarkably improve the wear resistance, the tipping resistance and the high temperature resistance of the cutter, so that the tungsten steel end mill has more excellent performance in the high-load and high-speed cutting process. In the prior art, the conventional tungsten steel end mill lacks a function of extending and retracting the length of the cutter, and when facing workpieces with different depths or replicas, the cutting position may not be flexibly adjusted, resulting in limited machining efficiency or machining quality. Disclosure of utility model In order to overcome the defects, the utility model provides a tungsten steel end mill with enhanced cutter tip protection, which aims to solve the problems that when facing workpieces with different depths or copied shapes, the tungsten steel end mill can not flexibly adjust the cutting position, so that the machining efficiency or the machining quality is limited.
