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.

3. Grinding methods differ in how parts are fed through the machine. The primary difference between the two most commonly used methods of centerless grinding is in how the workpieces are fed through the machine. Through-feed grinding is typically used for parts with consistent roundness across the length of the part. In this method, the ...

When exploring a new abrasive wheel for ID grinding, it's important to understand your current and potential grinding performance.
