- Variation In Outside Grinding Machines
On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, …

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 ...

Hold this at a 70 to 85 degree angle to the surface and pull toward you. The small peaks from the grinding scratch the surface, but with light pressure, the valleys ride above or at the ground surface. The checkerboard pattern reduces any stress induced in the surface- though this would be very improbable.
