Belt type grinding machine with sliding beam to press belt against work piece - has tensioning pulley actuated by pneumatic cylinder to ensure rapid re-adjustment in belt tension

The belt type grinding machine has a frame (2) which carries the driving roller (4) which is mounted on a shaft (6) and driven by the motor (8). A beam (16) is mounted in a sliding bearing (18) in the frame (2) so that it can slide longitudinally in a direction at right angles to the axis of the frame and is actuated by a pneumatic cylinder (24). One end of the beam (16) carries the contact roller (26) whilst the other end carries the turn round roller (22). The contact roller (20) is pressed against the workpiece (50). The belt tension is maintained by the tensioning roller (10). USE/ADVANTAGE - Belt type grinding machine with means to provide for a rapid adjustment in belt tension which allows a correspondingly rapid change in workpiece position.
