It is a very thin cup-style grinding wheel which permits grinding in crevices and slot. Saucer Grinding wheels: Saucer Grinding Wheel is an exceptional grinding profile used for grinding twist drills and milling cutters. This finds wide usage in non-machining areas, as these saw filers are used by saucer wheels to maintain saw blades.

The condition of your chips is also important information. When grinding, the workpiece is ground by the cutting edges of abrasive grains, discharging fine chips. The shedding, glazing, etc. of grinding wheel occur from the relationship between this chip shape and each cutting edge of abrasive grain. This phenomenon occurs from a constant timing.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

During grinding, the mirror is too rough to measure the focal length optically to any reasonable precision. Therefore, we take a mechanical measurement of the Sagitta, or Depth of Curve, and using some simple formulas calculate the focal length. This section will describe how to make this measurement accurately with simple tools.
