Cutting principle of circular slitting blade

Due to the light and fast cutting, the slitting round blade can cut grooves and cut off. The cutting speed can be doubled and the surface roughness can reach ra3.2. According to different processing materials, tictinal2o3 and tic tin composite coating can be applied on the surface of the blade, which can improve the hardness, wear resistance and wear resistance of the blade, and broaden the application range of the multi-functional turning tool, so that it can not only be used in difficult to machine materials, but also can be applied under the favorable conditions of intermittent cutting and uneven cutting depth. The multifunctional turning tool successfully realizes the multi-purpose of one tool. One tool can replace 34 ordinary turning tools, which greatly saves the clamping time and improves the production efficiency. Due to the adoption of advanced groove type, the problems of serious chip clamping and chip removal difficulty of conventional cutting tools are solved, and the surface roughness can reach ra3.2 or above, which improves the tool's durability; compared with ordinary cutting tools, it has the characteristics of reliable clamping and easy blade replacement; due to the small body and small blade of multi-functional turning tool, it is suitable for processing small and medium-sized parts This will cause a certain level of restrictions, and in the transverse movement, the cutting process of the circular blade of the rolling shear machine can not be fed, which is a problem to be solved.            Different cutting processes of slitting circular blade need different cutters to complete. It is often said that various milling machines or milling processes are enough to show that cutting this technology has been very important in the field of mechanical processing and has been widely used in many important parts of rotary blade steam turbine of rolling shear machine, such as steam seal ring, steam seal ring piston and bearing, etc. But because of the single cutting method. The time of tool changing and clamping is long, and the chip clamping is serious and the chip removal is difficult in the cutting process. In order to improve the efficiency and reduce the cost, a multifunctional turning tool is developed, which can turn the outer circle and the end face of the lathe while cutting the groove and cutting off, so as to realize the multi-purpose of one tool. The structure of multi-functional turning tool is improved from the structure of up pressure cutting tool, which solves the shortcomings of the original up pressure cutting tool and the cutting tool clamped by cutting force. The utility model is composed of a knife body, a blade, a pressing plate, a screw, etc. There are two difficulties to be solved when determining the structure of tool body. One is the determination of tool body material and the processing of tool plate
