Description

technical field [0001] The invention belongs to the field of metal working fluid, in particular to a configuration method of high-speed grinding fluid for bearings. Background technique [0002] It is well known that in high-speed grinding, since the movement speed of the abrasive particles relative to the bearing workpiece is close to the propagation speed of the compressive stress in the material, the deformation area of ​​the workpiece material will be significantly smaller, and the energy consumed will be more concentrated on the formation of wear debris. The energy required to remove the unit volume of material will be reduced, and the heat transformed by the deformation of the material will be more concentrated in the grinding debris, reducing the proportion of heat transmitted to the workpiece; due to the faster movement of the abrasive particles, the stress and heat in the deformed area are too late Conduction to the workpiece, so that the heat in the deformation are...

Problems solved by technology

[0003] Due to the fast grinding speed, more heat is generated in the same time, and the temperature in the grinding area is as high as 800-1000°C, which is easy to cause local burns on the bearing surface, and the heat will deform the workpiece and even cause cracks on the surface; and grinding A large amount of metal grinding debris and grinding wheel will be produced during processing, which will affect the surface roughness of the bearing workpiece; so when sele...
