Centerless Grinding Wheels
In Centerless grinding machine, the job is held between two wheels, rotating in the same direction at different speeds, and a fixture platform.
- One wheel, known as the grinding wheel, is on a fixed axis and rotates, such that the force applied to the job is directed downward, against the fixture platform. This wheel usually performs the grinding action by having a higher tangential velocity, than the job at the point of contact.
- The other wheel, known as the regulating wheel, is movable. This wheel is positioned to apply lateral pressure to the job and usually has either a very rough or rubber-bonded abrasive to trap the job. The regulating wheel specifications are also decided by the type of job to be grinded.
The speed of the two wheels relative to each other provides the grinding action and determines the rate at which material is removed from the job. During operation, the job turns with the regulating wheel, with the same linear velocity at the point of contact and (ideally) no slipping. The grinding wheel turns faster, slipping past the surface of the job at the point of contact and removing chips of material as it passes.
Centerless grinding Wheels size are generally of thickness 100 mm or more. As it is a without spindle application, the thickness has to be high (100 mm or above), so as to feed the job without holding the same.
We can also say it is grinding the outer surface of any cylinder and hence can be called as OD grinding wheels, supported vertical Centre as a stationary work rest blade and moving between cylindrical wheel & Centerless wheel.
Our Centerless wheels are specially designed for use in applications like bearing, automotive and bar grinding of various materials. These Centerless wheels are specially designed for
- Through feed
- End feed grinding
We as manufacturers of grinding wheels are proud by our achievement in terms of customer satisfaction. Grinding wheel selection chart and grinding wheel grade chart helps in taking the right decision for using the wheels
The thickness of Centerless Grinding Wheels is always more than Cylindrical Grinding Wheels
