Embodiment Construction

[0008] The present invention will be further described below in conjunction with embodiment.

[0009] A special formula for grinding automobile piston ring grinding wheel, the main abrasive composition is as follows:

[0010] Abrasive composition formula table (the percentage of each abrasive to the total volume of the abrasive)

[0011] Abrasive name Abrasive size Percentage of the total volume of the abrasive % 41CC F220 45 SSA F220 25 32A F240 10 CA F240 20

[0012] According to the characteristics of the double-end grinding method used in piston ring processing, which is not easy to dissipate heat, and the grinding fluid is water-based and oil-based, a special binder formula is designed, and its binding force to the abrasive is controlled within a certain range, so that the grinding wheel It is resistant to aging and has a certain grinding force. Its binder formula is as follows:

Abstract

The invention discloses a special formula of a grinding wheel for grinding an automobile piston ring. Adopted grinding materials comprise, 20% of 45A grinding materials of the F16 grain size, 60% of SSA grinding materials of the F16 grain size and 20% o f 31C grinding materials of the F24 grain size (the sum of the volumes of all the grinding materials is 100%). According to the further improvement, an adopted binder is composed of 12.5% of Y1 type resin powder, 4% of S6 type resin liquid, 0.5% of an M accelerant, 2% of a B enhancer, 3% of cryolite, 6% of gypsum powder and 15% of a pore forming material. By means of the special formula, the grinding yield is high, the grinding wheel dressing frequency is low, the spring surface machining quality is high, and the percent defective is low.

Description

technical field [0001] The invention relates to the technical field of grinding wheels, in particular to a grinding wheel formula. Background technique [0002] Automotive piston rings are used for sealing, heat dissipation, and lubrication in automotive internal combustion engines, and their materials have relatively high requirements for wear resistance, heat resistance, and abrasion resistance. At present, its manufacturing materials are mainly alloy materials and cast iron materials. In addition, the environmental requirements in the processing process of this industry are getting higher and higher, and the grinding fluids used are mainly water-based and oil-based. Grinding automobile piston rings uses existing grinding wheels, which cannot meet the requirements of alloy materials and cast iron materials at the same time, and cannot make the grinding wheels have a certain degree of wear resistance and self-sharpening, and the overall quality of grinding piston rings is l...
