Description

Soft material lathe tool

Technical Field

The application belongs to the technical field of machining, and particularly relates to a soft material turning tool.

Background

Currently, in machining, common turning tools include high-speed steel, carbide tools, and the like. However, when the cutter is used for processing materials such as rubber and tetrafluoroplastic, the materials are easy to deform, so that the product is scrapped, and the softer the materials are, the more easily the heat is generated during cutting, so that the deformation is caused, and the surface roughness is difficult to meet the design requirement. Secondly, the machining efficiency is low, although the cutting time can be shortened by improving the cutting speed, the cutting temperature can be obviously increased by increasing the cutting speed, soft materials such as tetrafluoroplastic and the like can expand and thermally deform, even change color, influence the machining quality of parts, aggravate cutter abrasion and reduce cutter durability.

Therefore, it is necessary to find a turning tool suitable for machining according to the characteristics of soft materials such as rubber and tetrafluoroplastic.
