1. According to the structure, it can be divided into integral turning tools, welding turning tools, machine clamping turning tools, indexable turning tools and forming turning tools. Among them, the application of indexable turning tools is becoming more and more extensive, and the proportion of turning tools is gradually increasing. 2. Tungsten carbide welding turning tools The so-called welding turning tools. 3. Machine clamp turning tool Machine clamping turning tool is a turning tool used to clamp the blade on the tool holder by using ordinary blades and mechanical clamping.
Cut off the turning tool
In order to reduce the friction with the machined surface, the two sides of the cutting part must be ground with a secondary declination angle, so the strength of the root is greatly weakened. In addition, when the parting turning tool is close to the center of the workpiece, the cutting speed tends to be zero, which is not conducive to cutting. Therefore, the cutting tool is very easy to "punch" (chipping) when working. Advanced parting turning tools generally make the main cutting edge into a chevron shape, and the front is ground into a ridge shape, so that the chips shrink laterally, and are stably discharged in one direction without clogging in the groove, and at the same time, the bottom of the cutter head is made into a convex belly shape to improve strength and stiffness.
Forming turning tools
The forming turning tool is a special tool for processing the forming surface of the rotary body, and its blade shape is designed according to the profile of the workpiece, which can be used to process the forming surface of the internal and external rotary body on various lathes. When machining parts with forming turning tools, the surface of the parts can be formed at one time, the operation is simple, the productivity is high, and the tolerance level IT8~IT10 and the roughness can be 10~5μm after processing, and the interchangeability can be guaranteed. However, the manufacturing of forming turning tools is more complex, the cost is higher, and the working length of the cutting edge is wider, so it is easy to cause vibration. Forming turning tools are mainly used to process small and medium-sized parts with forming surfaces in large batches.
