E-rotors

New technologies in automotive engineering such as electric motors pose new manufacturing challenges. The geometry of such e-drive shafts is usually very complex. Additionally, they need to be produced in high precision and efficiently in large quantities. The e-rotors required, which are made of materials such as 25CrMo4, require high-duty CBN grinding wheels to meet the grinding tolerances. In other words, the grinding surfaces need to be free of machining marks, free of firing/structural change, and must meet requirements in terms of shape and bearing tolerances..

This can be achieved by using MACH CBN 2.0 grinding layers in combination with highly damping MACH WHEEL wheel bodies! You’d like to find out more about MACH WHEEL grinding wheels and request personal consultation? We are looking forward to receiving your enquiry!
