Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
Grinding Machine. A grinding is metal cutting operation which is performed by means of a rotating abrasive wheel that acts as a tool.; These are mostly used to finish workpieces which must show a high surface quality, accuracy of shape and dimension. Mostly, it is finishing operation because it removes material in very small size of chips 0.25 – 0.5 mm.
A grinder (grinding machine) is a machine tool that uses a grinding tool to grind the surface of a workpiece. Most of the grinding machines use high-speed rotating grinding wheels for grinding, and a few use oilstone, abrasive belts and other abrasive tools and free abrasives, such as honing machines, ultra-finishing machines, abrasive belt ...
