GRINDING PROCESS

Grinding Process Grinding is a surface finishing operation where very thin layer of material is removed in the form of dust particles. Thickness of material removed is in range of 0.25 to 0.50 mm. Tool used is a abrasive wheel Grinding machine is a power operated machine tool where, the work piece is fed

Could Switching to Grinding Help My Manufacturing Process?

Oct 15, 2020  Converting a machining process to grinding. ... The need to stop an operation to replace and re-sharpen the cutting tools can lead to higher cost per part and frequent stoppages. Utilizing a grinding wheel can help minimize the down time and re-sharpening costs of machining operations. This is particularly true for new, difficult-to-grind alloys.
