Technical Field

The invention relates to the field of diamond grinding wheel dressing.

Background

The grinding wheel belongs to a cast product, the geometric accuracy of the grinding wheel surface is far less than the required accuracy of a grinding machine for grinding a roller, so that the dressing of the grinding wheel is very important for controlling the quality of the roller.

The diamond grinding wheel has high hardness, slow sand removal and large dressing difficulty. After the grinding wheel is replaced every time, the grinding wheel needs to be dressed for a long time, the grinding efficiency of the roller is seriously influenced, and great difficulty is brought to the supply of the steel rolling roller.

FIG. 1 is a schematic view of a diamond grinding wheel dressing surface by using a silicon carbide grinding wheel;

the device comprises a base, a diamond grinding wheel, a silicon carbide grinding wheel, a base with a sliding block, a linear guide rail and a diamond grinding wheel mounting platform, wherein the diamond grinding wheel is 1, the silicon carbide grinding wheel is 2, the base is 3, and the diamond grinding wheel mounting platform is 5.

Detailed Description

Firstly, the grinding and finishing effect of the green silicon carbide grinding wheel with low hardness on the diamond grinding wheel with high hardness is obvious, and firstly, the grinding surface of the diamond grinding wheel is quickly finished by using a common green silicon carbide grinding wheel. And the silicon carbide grinding wheel rotates in the same direction with the diamond grinding wheel, then the grinding surface of the silicon carbide grinding wheel is close to the grinding surface of the diamond grinding wheel, the grinding surface of the diamond grinding wheel is modified through the grinding surface of the silicon carbide grinding wheel, and the width of the grinding surface of the silicon grinding wheel is equal to that of the grinding surface of the diamond grinding wheel until no groove is observed on the grinding surface of the diamond grinding wheel.

Step two, if no bulge exists, the step three is carried out, if a bulge exists, a diamond pen is adopted to trim individual high points of the grinding surface of the diamond grinding wheel until no bulge can be observed on the grinding surface of the diamond grinding wheel, and the step one is returned after the trimming; often requiring repeated dressing cycles of green silicon carbide wheels and diamond pens.

Step three, finishing the diamond grinding wheel basically through the two steps, and finishing the grinding surface of the diamond grinding wheel by using a waste roller until the conditions are met simultaneously: the contact surface of the grinding surface of the waste roller and the diamond grinding wheel reaches above 2/3, the grinding sound is changed from sharp to heavy, and the roller surface after the waste roller is trimmed meets the grinding requirement, and the trimming is finished.

Starting from 2018 in 5 months, the high-roughness rough-surface roller for cold rolling is completely ground by the diamond grinding wheel, and the application of the diamond grinding wheel dressing method not only improves the grinding efficiency, but also ensures the roller surface quality.

The method of the invention shortens the dressing time of the new diamond grinding wheel, improves the grinding efficiency of the roller and ensures the supply-keeping capacity of the roller for steel rolling.
