History of GMT - Belt Grinders - part-2

GMT Belt Grinder

GMT Belt Grinding machines were targeted for aluminum die casting component for removal of runner and riser. This process is also heavy duty and we supplied machines to Sundaram Clayton Chennai for their aluminum foundry. 

Several models of Belt Grinders were developed to suit customer requirements. Single Ended, Double Ended using different belt sizes., light and heavy duty machines with built in dust extraction were also developed.

To educate customers and to create awareness on Belt Grinding GMT prepared a four page catalogue which deals with elaborate information on belt grinding.

GMT BELT GRINDING MACHINE

GMT is among the leading belt grinder manufacturer in India. Belt Grinding Machines achieve rates of high production efficiency, quality finish and economy never realized 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 micro-polisher. 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, do not occur.
Classification of Belt Grinding Machines
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.
