What is centreless grinding?
Centreless grinding is the name for a machining process in which material is removed from components or goods by means of abrasive cutting or grinding. It differs from centred grinding in that there is no spindle used to hold in place the material on which the work is being carried out. Instead, it is secured between a pair of rotary grinding wheels that rotate at pre-set speeds that determine the speed at which excess material is removed. Centreless grinding is generally much quicker than other grinding processes.
How does it work?
A combination of the cutting pressure and capability of the grinding wheel and the gravity acting on the work ensure that the work maintains contact with the regulating wheel and the rest blade. The regulating wheel (or control wheel) is normally made from a rubber bonded material that offers a frictional surface that is constantly advancing. This makes sure there is a steady, continual rotation of the work which is at exactly the same surface speed (or peripheral velocity) as the regulating wheel.
There are five main elements in the centreless grinding process:
- An abrasive grinding wheel
- A regulating wheel or control wheel
- A work rest blade
- The work that needs to be ground, which can be a component or piece of material
- Suitable guides that support the work as it enters and exits the wheels or as the grinding takes place
The arrangement of these elements can be different, depending on what type of centreless grinding is being enacted, but the principles of the process remain the same.
