Carbide turning tools for lathe machining of copper parts.
Carbide turning tool has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which basically maintains even at a temperature of 500 ℃ Unchanged, there is still a high hardness at 1000°C.
The cutting part of the turning tool consists of the main cutting edge, the secondary cutting edge, the front, the back and the secondary back.
The type of the front of the turning tool is mainly determined by the nature of the workpiece material and the tool material. The flat type with negative rake angle is suitable for carbide turning tools for machining high-strength steel and rough-cut steel castings. The flat type with chamfer is ground with negative chamfer on the plane of positive rake angle to improve the strength of the cutting edge. It is suitable for carbide turning tools for machining cast iron and general steel parts.
For turning tools that require chip breaking, a circular arc face type with a negative chamfer can be used, or a chip breaker can be ground on the front face of the flat type. Turning tools can be divided into outer circle, shoulder, end face, grooving, cutting, threading and forming turning tools according to their purposes.
There are also turning tools for automatic lines and digitally controlled machine tools. Turning tool, a tool mounted on a lathe for cutting metal materials. Turning tools are divided into high-speed steel turning tools, ceramic tools, carbide turning tools, cubic boron nitride turning tools, etc.
