Don't grind material for which the wheel is not designed. Do not grind/sand wood, plastic, or any other non-metallic materials. Note: Aluminum is not meant to be ground on a bench grinder. 19 Mounting Do make sure your bench and pedestal grinder is permanently mounted.

ppt vsi grinding - ristarsa.co.za. 1:40 or 50 (depending upon the grinding wheel) and is used for grinding the following materials. oCast iron or hardened steel oSoft steel oConnected carbide tools (using silicon wheel) In India we use IOC Servocut oils as cutting fluid. There is a special grade oil manufactured by IOC for grinding alone.

That means it can be used to grind long pieces of brittle materials and parts that might otherwise be distorted. 2. The centerless grinding process is deceptively simple yet precise. Since they owe much of their functionality to some basic principles of physics, centerless grinders don't have a lot of moving parts.

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.
