Problems solved by technology

However, high-speed cutting will also lead to a large amount of cutting heat, which will increase the cutting temperature and cause abrasive wear, adhesive wear and diffusion wear of the tool.
At the same time, the non-metallic elements in the high-temperature medium are easy to invade the tool, forming a brittle phase of the crystal tip and cracks, which greatly affect the service life of the tool

Abstract

The invention provides a vertical blade for a square milling machine and a production process thereof. The blade for the milling machine comprises a blade body and a hard layer covering the blade bodyand the thickness ratio of the blade body to the hard layer is 10:1-2; the hard layer is composed of composite fiber, plastic alloy particles and metal particles which are mixed in a mass ratio of 1:1.5-3:6-10. Through reasonable raw material selecting and blending and process improvement, after proper pretreatment and prefabrication of the raw materials, the blade is prepared by compounding, the comprehensive performance stability is stronger, the binding force between the body and the outer hard layer is high, the stiffness is significantly improved, and meanwhile, the blade has excellentheat dissipation and heat conduction stability, the service life is effectively prolonged, and the service quality of the blade is significantly improved.

Description

technical field [0001] The invention relates to the technical field of production and processing of milling machine blades, in particular to a blade for a vertical copy milling machine and a production process thereof. Background technique [0002] With the advancement of modern industry, the performance of industrial products is gradually improving, and the requirements for the machining industry are also increasing. Milling machines mainly refer to machine tools that use milling cutters to process various surfaces of workpieces. With the popularization of CNC machine tools, the application range of milling cutters has greatly increased. Usually, the milling cutter mainly uses rotational motion, and the movement of the workpiece and the milling cutter is the feed motion. It can process planes, grooves, and various curved surfaces, gears, etc. In addition to milling planes, grooves, gear teeth, threads and spline shafts, milling machines can also process more complex profil...
