Circular grinding is the most common grinding technique to produce precise cylindrical outlines and high surface qualities. This technique is divided according to the work piece bearing and the main feed direction, e.g. longitudinal grinding, cross grinding and infeed grinding.
Centerless-peripheral-longitudinal grinding (centerless through feed grinding) The most common type of clamping in external cylindrical grinding is between centers. This means that the workpieces must be centered at the front and are driven by a workpiece driver.

Infeed Grinding Services. Infeed grinding is a method of grinding in which the part is held stationary while the wheel is fed into the workpiece. Infeed grinding is used to grind parts with relatively complex shapes with multiple diameters and tolerances. Because of these differences, we grind one portion of the part at a time.
While you are dressing grinding wheels, aim to keep the infeed at .001. The vitrified bond will be pulverized by the unit, which is why the infeed needs to be very low. If you increase it, you also increase the risk of cracking the tool into the wheel. And if you go far away from .001, you could even degenerate the bond.

Infeed grinding is an economical alternative to traditional OD grinding in some cases, with minimal loss of concentricity. Precise geometrical forms such as steps, tapers, and radii can be quickly created in blanks. Modern grinders with CNC controlled dressers eliminate the need for costly cams to be made for complex part shapes.
