Description

Dressing device for groove processing grinding wheel

technical field

The utility model relates to the field of machining, in particular to a dressing device for a grinding wheel for groove processing.

Background technique

The prior art generally has methods such as turning, diamond roller, grinding and rolling to emery wheel dressing. Among them, the turning dressing method: using single-grain diamond (or a diamond pen made of finely crushed diamond, diamond dressing block) as a tool to turn the grinding wheel is the most commonly used dressing method. Diamond roller dressing method: a diamond roller made by embedding a large number of diamond particles on the surface of a steel roller by electroplating or powder metallurgy, rotates at a certain speed (to reduce the relative speed between the roller and the grinding wheel), and produces damage to the surface of the high-speed rotating grinding wheel. The grinding and rolling action makes the grinding wheel obtain a sharp working surface that matches the profile of the roller. Grinding and dressing method of grinding wheel: use a low-speed rotating superhard silicon carbide grinding wheel to grind against a high-speed rotating grinding wheel to achieve the purpose of dressing. Rolling and finishing method: use hard alloy discs, a set of rollers made of wavy white iron discs or grooved hardened steel sheets, and grind with the grinding wheel for rolling and extrusion. However, the above-mentioned methods all have the problems of single specification of the trimmable grinding wheel and low machining accuracy.
