With all the latest advancements in the field of automobiles and machine manufacturers, the function of bearing are now more crucial than ever before, thereby placing greater demands on quality of bearings.
Track grinding wheels must maintain form to ensure profile accuracy of the track of inner ring. This ensures that the wheels are dressed less often, leading to significant improvement in productivity and consistency of the process.
CUMI's Track grinding wheels are made with a special fusible glassy bond with sharp abrasive grain combination that ensures form holding while offering high material removal rates in high contact area application. An advanced manufacturing process ensures that the wheel's hardness is consistent through the wheel life and highest levels of safety are maintained.
