Composition and structure of turning tools.
Composition of turning tools
A turning tool consists of two parts: the head and the tool body. The cutting head is used for cutting, and the cutter body is used for installation. The knife head usually consists of three sides, two edges and one tip.
The front surface is the surface through which the chip flow passes.
The main flank surface is the surface opposite the cutting surface of the workpiece.
The secondary side surface is the surface opposite the workpiece surface being machined.
The main cutting edge is the intersection line of the front surface and the main side surface, which is responsible for the main cutting work.
The secondary cutting edge is the intersection line of the front surface and the secondary side surface, it is responsible for a small amount of cutting work and plays a certain role in smoothing.
The tool tip is the intersection of the main cutting edge and the secondary cutting edge, which is usually a small transition arc.
Structural form of a turning tool.
The most commonly used design forms of turning tools are as follows:
(1) Solid turning tool The cutting part of the tool head is obtained by sharpening. The material of solid turning tools is mainly made of high-speed steel, and is generally used for low-speed cutting.
(2) Welding turning tools Weld the carbide blade to the cutting head. Different types of turning tools can use different blade shapes. Welded carbide turning tools for high-speed cutting.
