GMT is among the leading belt grinder manufacturer in India. Belt Grinding Machines achieve rates of high production efficiency, quality finish and economy never reallized in any other method of grinding or polishing. For example, by changing grit sizes, a machine may be converted from a heavy duty grinder to a fine micropolisher.
Belt grinding machines can be adopted for semi-automatic or fully automatic working. Further, in most applications, belt grinding imposes less strain on the workpiece when compared to other forms of grinding, cracking, burning etc, are non-existent. |

Abrasive belt grinding machines are usually classified by the surface that forms the backup of the coated abrasive at the work area. This backup has an important effect on the material removal rate and on the finish. The backup governs choice of contact pressure, the angle of cut and the speed of operation.
Belt Grinding Machines may be broadly classified according to the backups used as :
- Platen Grinding Machines:
- Contact Wheel Grinding Machines
- Free Belt Grinding Machines
- Centreless Grinding Machines
In construction, all the machines are similar. A coated abrasive belt runs over two pulleys - one driving pulley one idler pulley. There is (a) provision to prevent the belt from 'walking' or 'running' off the pulleys. |
