What are the types of tools in machining?
Cutting tools are very important in the machining process and are directly related to the processing quality and precision. Today, with the rapid development of the processing and manufacturing industry, various new materials and new processes are emerging one after another, and the materials and processes of cutting tools are also constantly changing. Changes are being updated. Faced with the increasing processing requirements, as a machine operator, it is necessary to understand the types of tools and the selection criteria of tools.

What are the types of tools in machining?

1. Classification according to tool material
High-speed steel tools: high flexural strength and impact toughness, and good workability.
Cemented carbide: The chemical vapor deposition method is used to coat titanium carbide, titanium nitride, aluminum oxide hard layer or composite hard layer, so that the tool wear is low and the service life is long.

2. Classification according to the cutting motion of the tool
General tools: commonly used are turning tools, planing tools, milling tools, boring tools, drills, reamers, reamers and saws.
Forming tools: commonly used are forming turning tools, forming planers, forming milling cutters, broaches, conical reamers and various threading tools.
Generating tools: commonly used hob, gear shaper, shaving cutter, bevel gear planer and bevel gear milling cutter.

3. Classification according to the working part of the tool
Integral type: The cutting edge is made on the cutter body.
Welded: brazing the blade to the steel body
Mechanical clamping type: the blade is clamped to the cutter body, or the brazed cutter head is clamped to the cutter body.
