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 operations: Cylindrical grinding 1. External cylindrical grinding (also called center-type grinding to distinguish it from centerless grinding) is performed much like a turning operation. 2. The cylindrical workpiece is rotated between centers to provide a surface speed of generally 18 to 30 m/min, and the grinding wheel rotating generally at 1200 to 2000 m/min, is engaged to …
use requires higher grinding pressure. A typical application for it is grinding tool steel in rigid grinding machines. Examples of this type of abrasive are SG (Seeded Gel) from Norton and Cubitron from 3M. 2.

The same principles used in operating a manual machine are used in programming a CNC machine. The main difference is that instead of cranking handles to position a slide to a certain point, the dimension is stored in the memory of the machine control once. The control will then move the machine to these positions each time the program is run.
Grinding is a term used in modern manufacturing practices to describe machining with high-speed abrasive wheels, pads, and belts. Grinding wheels come in a wide variety of shapes, sizes, and types of abrasives. In recent decades, grinding has been evolved both for producing very high quality parts and for fast economic production.
