Low stress grinding (LSG) uses wheel speeds of about 20 m s1 and can usually be done on conventional grinding machines in any of the grinding modes. Most surface grinding operations use wheel speeds of 30–35 m s1. High speed (high efficiency) grinding is a rapid metalremoving process using special wheels with speeds of 100 m s1. Grinding

Factors affecting proper coolant appliion when grinding

Aug 11, 2017 · Grinding is a thermally dominated process, meaning a high percentage of process heat initially enters the part before coolant quenches it. Unless the coolant is applied at the correct flow rate and pressure, and the proper input conditions are selected, this process can lead to undesirable rehardening burn, thermal softening and tensile residual stresses.
