Temperatures in High Speed Grinding of TC4 with a Vitrified CBN Wheel
An investigation is reported on the temperature in grinding of titanium alloy (TC4) by using a vitrified CBN wheel at grinding speed up to 120m/s. The temperatures under different grinding parameters were measured by using a sandwiched foil thermocouple. Coupled with the SEM observations on the ground workpiece surfaces, characteristics of temperature in high speed grinding were analyzed and compared with the temperatures in grinding at normal speeds. It is found that grind speed is the most significant factor to determine temperatures, which might be associated with the increase of material removal in the plastic way at higher grinding speed.
