Monitoring grinding process is challenging due to the numerous cutting edges and as well as varying cutting edge geometries. The grinding process is transient and metal removal mechanism will change with respect to time [1]. Because of these factors there is a need to monitor the grinding process for effective control of the process.

Grinding is a mechanical removal process applied mainly in finishing operations of hardened workpieces to produce small tolerances with high-quality. Especially, centreless grinding is broadly used in serial production due to the requirement of high accuracy in process. Centreless grinding is used to produce several mechanical components such as, bushings, …

Throughfeed centreless grinding is characterised by its complexity, non-linearity and sensibility to a large number of parameters that influence process stability and workpiece accuracy.

In order to obtain good fatigue resistance and surface quality for the inner raceway of a bearing, the cut-in-type grinding test of M50 bearing inner raceway was carried out by using axial ultrasonic vibration. Based on abrasive kinematics, the abrasive trajectory cut-in-type axial ultrasonic vibration grinding is established, and the mathematical models of surface …

Bhagwansons has successfully developed processes for centerless grinding on a very broad range of parts. Many of these are shown below:

Centreless grinding is an abrasive process that uses grits with undefined geometry and elevated complexity due to the great number of input variables in its setup [6, 7]. The difficulty to control ...

Centreless grinding, an efficient manufacturing process, has been widely used for high accuracy and productivity manufacturing of cylindrical components, such as silicon-ingots, bearing raceways, catheters and pin-gauges, and is not limited to workpiece material properties, –31].

Give sufficient time for spindle bearings to warm up. (Warm up grinding machine to stablize bearing temperature.) Tighten thrust bearing. Slightly longer and more widely spaced marks: Wheel spindle run-out or out of round: Replace spindle if it is twisted or warped, or out of round. Regularly spaced marks: Vibration: Rebalance wheel.

Inside diameter grinding, also called as internal grinding, is used for grinding the inner diameter of tubular object. Workpiece or object will have already drilled hole and internal grinding process will be performed to finish the inner surface of workpiece with the help of small grinding wheel rotating at higher revolution per minute.

In thrufeed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel (as illustrated in the diagram, right). Both wheels rotate in the same direction, but at much different speeds. …
