Precision Abrasive Tools

Darmann manufactures a wide variety of custom, conventional and superabrasive products used to superfinish, grind, and dice a wide range of parts.

Superfinishing

Darmann understands that in the world of precision metalworking, the difference between good and exceptional often comes down to microns. Our superfinishing stones are engineered to achieve that ultimate level of surface finish, removing the amorphous layer left by previous processes to create unparalleled smoothness and geometric accuracy.

Darmann’s superfinishing stones are deployed in critical through-feed processes to finish cylindrical parts such as tapered rollers, piston pins, shock absorber rods, shafts, and needles.
