gridding disc maximum temperature

Grinding Wheel Use & Precautions Safe Handling and

Grinding wheel at uniformed temperature is relatively safe even at high temperature (in particular dry grinding). Temperature differences of 60-70℃ may cause wheel breakage. Therefore, use softer grade grinding wheel (suitable grit size, grade, and structure) at suitable grinding pressure.

What is the temperature of grinding sparks? - Quora

Answer Wiki. There is a scale called color temperature. The exact temperature from color is called pyrometry. Metal glowing color is exactly the temperature of the surface. White hot is 1200 C, yellow hot is 1000, red hot 650 C. Light bulb filaments are tungsten and if halogen, are 5000 C when full power. So yes, 2000F is close average.

CALCULATING SFPM The performance of grinding wheels and quality of the finished workpiece is affected by how fast the abrasive grains sweep over the workpiece. That speed affects surface quality, workpiece burn, material removal rates, and other factors. Since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, RPM isn't a useful measure.
