    - The centreless grinding is a process of grinding metallic parts in which the piece to be ground is supported on a work-rest, and passed between a grinding wheel running at a high speed and control wheel running at a slow speed.

    - The advantages of centreless grinding process are as follows:

    1. Less metal needs to be removed during centreless grinding process due to the existence of a true floating condition.

    2. The requirement of wheel adjustment is minimum in centreless grinding process.

    3. The centreless grinding operation can be applied equally to both internal and external grinding.

    - Besides these advantages, the one of the disadvantages of centreless grinding process is that its set up time is usually large.

    - Therefore, the sentences (1), (3) and (4) are true for centreless grinding operation.
