COMMUTATOR STONES
Commutator stones (or collector grindstones) are used in electric motor construction. To grind the commutator or slip ring. We manufacture commutator stones in the dimensions and grain sizes you require.
These commutator stones are used to process deformations of a commutator or slip ring of rotating electrical machines. By grinding the collector or slip ring, damage can be processed and the exact roundness and required roughness can be restored.
