A grinding wheel is a precision tool with thousands of cutting points on its surface - abrasive grains that are held in place by a bond matrix (hence these are known as bonded abrasives) and separated by pores.. These pores are hollow spaces between abrasive grains and the bond, which help with the clearance of discarded metal chips in the grinding process.

What is the cutting time when 100mm workpiece is machined at 1000min -1 with feed = 0.2mm/rev ? (Answer) First, calculate the cutting length per min. from the feed and spindle speed. l=f×n=0.2×1000=200 (mm/min) Substitute the answer above into the formula. Tc=lm÷l=100÷200=0.5 (min) 0.5×60=30 (sec)The answer is 30 sec.
