How to grind the R angle and repair the grinding wheel in the metal stamping die, the more detailed the solution, the better.

Go to the mold parts store to buy a universal grinding wheel dresser.

Characteristics of universal grinding wheel dresser;

Universal grinding wheel dresser

Universal grinding wheel dresser is suitable for surface grinder and tool grinder. With the design of sliding base, grinding wheels of various sections with arbitrary right angles and arcs can be trimmed.

Calculation formula of universal dressing grinding wheel:

Return to zero: H=L= zero r

Trimming convex arc: H=L+R

Trim concave arc H=L-R

H- the distance between two quasi-tip outer buses

R- the radius of the arc to be trimmed

L- the distance from the tip of the diamond tool to the reference plate
