- where the requirement of cylindrical grinding machines
The fundamental design is the same in both cases, but the universal machine can be adopted for internal grinding operations as well. In cylindrical grinding operation, the work is mounted between two centres and is rotated. A grinding wheel is mounted on a spindle and revolves at a much higher r.p.m. than the work.

Roll grinding is found mostly in steel and paper mills where precision is paramount to reshape and polish rolls. Most roll grinding wheels are large in diameter (700-1080mm) and thickness (50-150mm). Depending on the surface finish required, Norton can provide roll grinding wheels with specific dimensions and specifications for your application ...

Grinding machines, like broaching machines, operate over a range of speeds depending on the type of machine being used.These range from approximately 1250 to 2000m min −1, although in high-speed grinding speeds of up to 5400m/min are achievable (Schey, 1987).The two most common grinding applications are cylindrical grinding and surface …

The internal grinding is a high-speed operation, because the grinding wheel rotates at a speed of 30,000 rpm or even more. Internal grinding can be one of three types: traverse grinding, plunge grinding, and profile grinding [2]. Finally, centerless grinding is typically the same as cylindrical grinding.
