Grinding operations prevent later splashing and popping of chrome layer from the roll surface which can result as a chrome peeling. After rolling operation, rolls have to be re-ground to remove metallurgically damaged stock to limit costs …
· This paper presents a study of a vibration problem in a roll grinding machine. The rolling contact between a metal roll and the grindstone may cause the pattern formation on the roll surface during the grinding operation. A self-excited vibration excitation or so-called regenerative chatter excitation is present in the process.

Thread rolling is the preferred method for producing strong, smooth, precise, and uniform external thread forms. Outsourced thread rolling processes are often more efficient than producing threads by cutting or grinding, especially on parts made from difficult metals. Customers who prefer to supply their own machined parts and blanks, rely on ...
Roll grinding wheels are ones used for grinding big rolls of steel mills. It is a glorified form of cylindrical grinding in which the roll is held between centres and the wheel traverses across, thereby grinding the rolls. The benefits of this grinding wheel are more removal, less dressing required, freer cutting (less heat), and it is more ...
· Roll grinding aluminium & copper. Unchanging material thickness and a fully defect-free surface are the major requirements for roll grinding in aluminium & copper rolling mills. With rolling speeds of up to 2,500 m/min in the foil rolling mill, this is a big challenge for the grinding pattern of the roll and its geometric precision.
