Nov 21, 2014· GRINDING MACHINE 3. Introduction • A grinding machine, often shortened to grinder, is any of various power tools or machine tools used for grinding, which is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel''s surface cuts a small chip from the work piece via shear deformation.
cutting action like in case of grinding. Machine Lapping Machine lapping is recognized as fast lapping process. Gudgeon pins with25 mm diameter and 75 mm long can be lapped at the rate of 500 units perhour. Mechanical lapping machines have vertical construction with thework holder mounted on the lower table which is given oscillatory motion.
