Title Evaluate the shape of the grinding wheel
Description

Because the surface of the grinding wheel directly affects the quality of the grinding surface, it determines the grinding performance and service life of the grinding wheel. Therefore, it is of great significance to evaluate the grounding of the wheel after trimming, and it can be used to guide the design of the wheel dresser and the dressing of the grinding wheel.

1. Ideal grinding wheel shape and its evaluation

The state of the thin abrasive cutting disc for metal can be used to predict the amount of grinding surface. In order to make the distribution of the cutting marks on the surface of the workpiece to be more uniform and reduce the roughness of the grinding surface, the grain spacing of the surface of the grinding wheel should be uniform; at the same time, in order to make the grinding particles in the grinding

The depth of the cutting marks on the surface of the workpiece is uniform, and the surface roughness of the surface is small. Therefore, the height distribution of the surface of the grinding wheel is uniform, that is, the contour is good; and in order to use the micro-knife in a semi-blunt state under appropriate grinding pressure The friction generated between the surfaces of the workpiece acts as a polishing device to obtain a grinding surface with high precision and small roughness, achieving high precision, small roughness, and grinding. Therefore, the particles on the surface of the grinding wheel should have the micro-knives described above. The ideal wheel has the three characteristics of uniformity, uniformity and micro-blade.

The ideal evaluation of the quality of the grinding wheel is as follows. The ideal wheel topography should have three characteristics. In order to make the abrasive grain distribution on the surface of the grinding wheel uniform, the surface of the thin flat cutting disc should obey the following two directions.

Uniform distribution on the uniform distribution of abrasive grains in the width direction of the grinding wheel and uniform distribution of abrasive grains in the circumferential direction of the grinding wheel
