Stripping, smoothing, polishing, grinding: Good contact is essential for optimum transmission. We offer our customers lots of helpful material here. Our pumice rods help you to adjust the run surface of the carbon brushes exactly to the radius of the contact surface, and to produce the required degree of roughness. In this way optimum conditions for the best run results can be created right from the beginning. Whether it's solid grindstones in different grains or flexible rubber-bound polishing rods: At MACK, you can enjoy a rich assortment of versions, sizes, and materials for the smoothing and polishing of slip rings and collectors.
