Form grinding wheel dresser

Abstract

The invention relates to a form grinding wheel dresser, which is characterized by comprising a dresser fixing seat arranged on a grinder bench, and a clamping groove is arranged at the upper end of the dresser fixing seat; a grinding wheel dresser is arranged in the clamping groove, and comprises a cylindrical cemented carbide substrate; and a flaky synthetic diamond grinding head is arranged on the upper surface of the cemented carbide substrate, and the surface of the synthetic diamond grinding head is a grinding contour. The form grinding wheel dresser provided by the invention has the following advantages that: the manufacturing process is simple, the preparation is fast, the manufacturing cycle is significantly shortened to about 10 days; the cost is low and is about one-tenth of the cost of traditional diamond roller wheel; the installation is convenient, and an additional high-precision roller wheel turning device is not needed; the shape accuracy of 2 microns can be achieved; the production conversion is fast, and the form grinding machine can realize the small batch production of many varieties; the life is almost the same as that of the traditional diamond roller wheel; and more complex shapes can be processed so as to break through the bottleneck that special shaped diamond roller wheels can not be produced.

Description

technical field [0001] The invention relates to a grinding wheel dresser, in particular to a profiled grinding wheel dresser for a grinding wheel of a grinding machine. Background technique [0002] Profile grinding can machine complex shapes with high precision, but depends on the precision of the wheel dresser. Such as figure 1 As shown, the conventionally used diamond roller dresser 1a is a ring-shaped object with a generatrix of a specific shape, and the surface is embedded with fine diamond particles by electroforming, and the diamond roller dresser 1a rotates under the action of the rotary drive 2a, During dressing, the grinding wheel 3a moves up and down during the rotation, and contacts with the dresser, and the diamond particles remove useless parts on the grinding wheel to make it into shape. The diamond roller needs to be made into a specific shape through a complicated process, and the precision can reach 2 microns, but the preparation period is as long as seve...

AI Technical Summary

Problems solved by technology

The diamond roller needs to be made into a specific shape through a complicated process, and the precision can reach 2 microns, but the preparation cycle is as long as several months, and the price is expensive. The electroformed roller is also easy to wear, especially at the sharp corners, and the cost-effective ratio is poor.

In addition, some special-shaped rollers are difficult to manufacture domestically and must be imported
