Problems solved by technology
[0004] But the current chemical mechanical polishing equipment is only suitable for polishing flat carbide inserts
However, most cemented carbide inserts are designed with chip breakers due to the technical requirements of cutting chips, maintaining machining accuracy, and prolonging the life of cemented carbide inserts. Due to the limitation of chemical mechanical polishing equipment, chemical mechanical polishing technology cannot be applied to hard alloys with chip breakers. Chipbreaker surface finish for carbide inserts

The invention relates to a chemical mechanical polishing equipment for a cemented carbide blade with a chip breaker, aiming at the limitation of the existing chemical mechanical polishing equipment that the chemical mechanical polishing process cannot be applied to the surface of the chip breaker of a cemented carbide blade with a chip breaker Design for technical problems of polishing. It includes a general device, a Z-direction precision sliding table, a brush device, a vibration motor, a blade fixture and a polishing liquid supply device. The Z-direction precision slide table is connected to the rear side of the general device, and the brush device is connected to the Z-direction precision slide table. , The vibration motor is installed on the front side of the brush device, the blade clamp is connected with the universal device, and the polishing liquid supply device is connected with the brush device. Through the precise control of the brush and polishing liquid, the present invention utilizes the chemical corrosion of the polishing liquid and the mechanical wear of the brush on the hard alloy blade with chip breaker to realize the process of chemical mechanical polishing, which has the advantages of simple operation, convenient control, and easy operation The advantages of reliability and convenient adjustment.
Description
technical field [0001] The invention relates to the technical field of polishing equipment, in particular to a chemical mechanical polishing equipment for a cemented carbide blade with a chip breaker. Background technique [0002] Cemented carbide tools have high strength and hardness, good wear resistance and oxidation resistance, cutting speed and cutting life are higher than high-speed steel carbide tools, and have become the leading carbide tools in developed countries. The quality and performance of cemented carbide tools directly determine the production level of the manufacturing industry. The surface quality of cemented carbide tools (surface roughness, thermal deformation, cracks, scratches, and surface damage) is an important factor affecting the durability of cemented carbide tools. Diamond grinding wheel grinding is the most commonly used processing method for cemented carbide tools in China, but ordinary grinding is easy to cause damage to the surface of cemente...
