The diamond band saws BS270 S/X/XY are small production machines

The diamond saw band runs over two rollers in an endless loop. It is driven and pneumatically tensioned by the height-adjustable upper roller. The band tension is set by the adjustable air pressure on the pressure reducer. Near the work area, the band is guided by two zero-backlash guide roller units. The wire is driven by a three-phase current motor controlled by a frequency transformer. The speed of the band can be set at any point between 200 and 2200 m/min.

The travel of the band unit is program-controlled with a ball screw and the servomotor (X axis). Travel and feed rates are programmable. The tables can be positioned with the help of buttons. Control: Mitsubishi touch-screen PLC control with menu-driven programming. The BS270 X is upgraded to the CNC-controlled 2-axis BS270 XY by fitting it with a servomotor-driven Y table.

In the basic version, the machine is operated manually. It can be tilted with an adjustment screw such that the linear movement of the X table is accomplished by its own weight. It can be operated with a dry cut or alternatively with cooling. For dry cutting, a suction unit is attached to the exhaust connector provided. For the stainless version, pure water can be used for cooling.
