Incenterless grinding, the workpiece is held between twogrindingwheels, rotating in the same direction at different speeds.Onegrindingwheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs thegrindingaction by having a higher linear speed than the workpiece at the point of contact.
Dec 08, 2016· 5.Anglesaffect success in centerlessgrinding. Theanglesat which the centerlessgrindingwheels contact the part are critical to achieving the proper roundness and tolerance. Generally, the centers of the regulating andgrindingwheels are set at the same height on themachine, and the center of the workpiece is situated higher.

Grinding/ Polishing / EtchingGrindingand polishing is the final stage in the sample preparation process and consists of several steps. Each step uses finer abrasive than the previous one, the ultimate goal being to produce a deformation-free, scratch-free and highly reflective sample surface.
Materialswith high stiffness increase the damping capacity of amachine. This prevents chatter and periodic applied forces. This is implemented by using internal and external damping methods. Internalmaterialsis the selection ofmaterials, while external damping is external devices, such as the shock absorbers on cars.

Type 28 (conical)grindingwheels are normally used to grind on flat surfaces to removematerialon a widergrindingpath. These conical wheels also operate best at a lowergrinding angle, at about 5 degrees, so they help reduce operator fatigue. This introduces another critical factor: choosing the rightgrindingwheel type.
Machinability of a metal is influenced by themachinevariables (rigidity, power and accuracy ofmachine), tool variables (toolmaterial, geometry and type of cut), cutting conditions (speed, feed and depth of cut) and the workmaterial properties. How each of these variables affect machinability is discussed below.

The rake angle is 15o for threading material of 30 HRC, and it is increased to 30o for threading material as soft as 65 HRB. The workpiece diameter should be 1 to 1½% undersized to prevent binding in the die. The exact undersize required will vary with alloy and temper, but can be determined by one or two trials.
