Jun 02, 2008· The roundness of a component could have an effect on oil retention, oil disbursement, fuel leakage, excessive vibration, friction, as well as many other critical functions of the final assembly. Most parts measured for roundness are produced on grinding machines.
A generic intelligent control system (GICS) has been developed to control a range of grinding processes using a group of selectable control strategies. The GICS has been developed on a personal computer. This paper describes an example: implementation for internal grinding on a Jones Shipman 1300X grinding machine.

Jul 21, 2014· After taper, the next most common boregrinding problem is roundness. Maintaining roundness to within the specification is critical to the ultimate performance of the component —affecting such things as lubricant retention and distribution, leakage, vibration levels, friction and ease of assembly.
Dec 08, 2016· The primary difference between these two most commonly used methods of centerless grinding is in how the workpieces are fed through the centerless grinding machines. Throughfeed grinding is typically used for parts with consistent roundness across the length of the part.
Dec 08 2016 · Otherwise it can be difficult to hold tolerances for roundness and straightness and thermal damage can even cause the grinding wheel to blister and crack. 7. You can teach an "old" process new tricks. Although centerless grinding is a mature process today s grinding machines are equipped with newer features that enhance performance.

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. The purpose of the grinding wheel is to remove material from the workpiece and improve part OD quality.
