These grinders are used for grinding round and hollow jobs whether the internal surface of this job is completely round, ditched round, or is in taper. Small grinding wheels of 3 cm to 5 cm, are used in such grinders. Sometimes grinding wheels of special shape 0.2 cm to 0.3 cm. These grinders can be divided into two parts. a. Chucking Grinder
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.

Grinding wheels used in producing ground threads are single-or multiple-rib. Single-rib types are used for grinding longer threads and feed longitudinally for the required length of thread. The multiple-rib type of grinding wheel is generally used for forming short threads. This type of wheel is "plunged" into the workpiece to produce the thread.
