Centerless Grinding

Centerless Grinding is a type of grinding in which cylindrical parts are not held between centers (cylindrical grinding) but rather are supported on a work rest and rotated.

Small amounts of material are then removed from the outside which reduces it in size.

The process can be applied to parts without the requirement of centres as needed with universal or cylindrical grinding.

The part is placed upon a work rest and this – together with the regulating wheel – is fed forward.  This in turn pushes the part against the grinding wheel.

In order to obtain the axial movement of the part past the grinding wheel, the regulating wheel is tilted at a slight angle from horizontal.  A typical angular adjustment to do this would be between 0 and 10 degrees.

There are two types of centerless grinding.

The first is Through Feed Grinding where the part is fed into the machine along the work blade.

The second is Plunge Grinding where the work piece is placed between the wheels on a work blade and the grinding wheel is “plunged” into the part.

The greatest benefit of centerless grinding is that extremely accurate tolerances and finishes can be achieved at an excellent price, as the process is highly efficient and cost effective compared to other types of grinding.
