Abstract

The invention provides a grinding device with an inverted V-shaped slot in a grinding wheel and a grinding method, and belongs to the technical field of metal cutting and processing. The grinding device comprises a grinding fluid flow rate control system, a grinding fluid conveying system and a grinding processing system. In order to obtain a high-quality grinding surface, the inverted V-shaped slot is formed in the periphery of a grinding wheel base body, a grinding fluid spray hole is formed in the slot, a grinding fluid is simultaneously sprayed at the two sides of the grinding wheel, the grinding fluid enters a grinding region through spray holes, and the flow rate of the grinding fluid can be automatically regulated. According to the grinding device and the grinding method, the temperature of the grinding region can be effectively reduced, vibration in the grinding process is reduced, the grinding surface quality is remarkably improved, semi-automatic production can be realized, and the grinding device and the grinding method are especially suitable for high-speed precision grinding of a deep trench.

Description

Technical field: [0001] The invention belongs to the technical field of metal cutting, and in particular relates to a grinding device and a grinding method with a herringbone groove on a grinding wheel, which is especially suitable for large-depth, high-speed, high-precision grinding of surfaces and grooves of quenched parts. Background technique: [0002] The development of modern equipment has higher and higher requirements on the surface quality of its key parts. For example, the surface roughness Ra of the emitting foil receiving infrared rays in the infrared detector reaches 0.015-0.01 μm. As the final process in the machining process, grinding plays a key role in controlling the surface quality of products and has been widely used. The grinding wheel is used as a grinding tool. During the grinding process, a large number of abrasive grains distributed on the grinding wheel rub, score and cut the surface of the workpiece. Due to the fast cutting speed during the grindi...
