Adjustments

Air treatment unit (MA version)

In the MA version of the

S---20DS

, the machine’s pneumatic circuit actuates the

vice by means of a pneumatic cylinder.

The compressed air is treated and purified at the inlet to the system by an air

treatment unit, which, if so calibrated, regulates the pressure at about 6 Bar,

irrespective of the pressure in use in the factory circuit.

The pressure can in any case be set should the workpiece be subject to deforming

stress or is unstable during the cutting process; the vice should be positioned at

2---3 mm from the piece before final clamping.

The user is requested to have available in the workshop a plant having the

characteristics described in CHAPTER 4.

The diagram below shows an exploded view of the air treatment unit: the working

pressure is regulated by rotating the knob indicated by the arrow, and is displayed

on the pressure gauge.
