4.2 DESCRIPTION OF THE MACHINE AND ITS COMPONENTS
The Special 380 A band sawing machine produced by MACC has a sturdy frame made from welded and painted sheet-
steel. The upper surface is designed to allow the complete draining away of the cutting fluid. The band holding bow is
made of aluminium and has generous dimensions, providing the cutting unit with the necessary strength and precision.
The vice unit is made of cast-iron and clamps the material to be cut securely. The numerical control device allows the
required length to be present and provides high repeated-cut precision. The coolant pump is fitted to the machine base.
A electromechanical device with pressure switch for band tightening, prevents the band from advancing in the event of
insufficient tension and moreover allows ideal operation conditions to be restored at any moment. The main switch is
located on the front panel. The blade is protected by a guard with interlock which covers the upper area and the
handwheels and by two adjustable lower guards which protect the operator from ejected shavings and coolant. The
machine is supplied with a set of service spanners and rod support.
