Turning tool machining process favorable for machining efficiency

Abstract

The invention discloses a turning tool machining process favorable for machining efficiency. The turning tool machining process comprises the following steps of discharging blank, forging, cutting machining, thermal treatment and grinding machining which are performed in sequence, wherein the blank is W2MoCr4V2Co8 high-speed tool steel; the thermal treatment comprises preheating, heating, preserving heat, quenching and tempering which are performed in sequence; the preheating is performed by heating gradually in stages; the quenching is oil cooling; the process can also comprise an annealing step between the steps of forging and cutting machining; in the annealing step, the forged blank is heated in steps. The process route is simple; the hardness value of the obtained turning tool can reach over 70 HRC; moreover, the turning tool has high wear resistance and thermal hardness.

Description

technical field

[0001] The invention relates to the field of lathe tool processing and manufacturing technology, in particular to a turning tool processing technology that is beneficial to processing efficiency. Background technique

[0002] In the machining industry the lathe is considered the working "mother machine" of all equipment. Lathes are mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces, mainly cylinders, and are the most widely used type of machine tools in machinery manufacturing and repair factories. Turning tools are used for turning and have a Cutting tool. Turning tool is one of the most widely used tools in cutting.

[0003] With the development of modern manufacturing technology, high-speed steel turning tools are widely used in cutting. During use, the cutting part of the turning tool has to bear a lot of pressure, friction, impact and work at a higher temperature, which makes high-speed Steel turning tools are mo...
