Effects of Cooling Methods on Temperatures in Vertical Grinding Stone

摘要

In the present study, natural black granite was ground with a cup-type resin bonded diamond wheel on a vertical spindle grinder. Grinding temperatures under different cooling conditions were measured using a foil thermocouple. Through comparing the measured grinding temperatures, the effects of operating parameter, applied coolant and cooling method on the temperatures were discussed. The results show that the grinding temperature increases with the increasing spindle speed and pressure. The internal application of lubricant oil and coolant may be beneficial to reduce damage to the diamond wheel and workpiece.
