QUALITY DESIGN - Skilful engineering and imaginative design give every MEGA Band Saw exceptional cutting capacity.


• A completely automatic cutting cycle synchronised with an automatic bar-feed mechanism and stock clamping action
       provide accurate repetitive cutting.

• An excellent blade tensioning system and guides keep the blade aligned and under constant load at all times.

• A hydraulically controlled cutting feed maintains a constant cutting rate regardless of the workpiece cross section.

• A power-driven brush continually flushed by a cutting fluid spout keeps the blade and saw guides free of chips for
      smoother cutting.
• A quick approach and normal feed rate selector are equipped to cause the blade to quickly descend into position.

• A cutting piece counter is used to preset the number of cuts required during automatic operation.

• Two hydraulically operated vises, one a fixed front vise, the other an indexable travelling vise in the rear side.

• The hydraulically operated nesting fixture is designed for high production multiple sawing of stacked bars, small
      rounds and tubes. The fixture contains vertical cylinders mounted on the index and front vises. It holds stacked
      work firmly to prevent vibration.
• A cutting length presetting device is built into the saw to preset the required cutting length of a workpiece during
      automatic operation. It is simply operated by means of a read-out digital device.

• Multiple stroke preset counter: when a cutting length of more than 16 is required, the number of strokes can be
      preset on this counter. The counter is capable of being set to a maximum of three strokes 48 (1200 mm )
      ( nine strokes 144 is optional )

SAFETY DESIGN- Every MEGA Band Saw is factory equipped with:

• Safety and thermal overload switches.

• Well guarded blades and wheel covers.

• Saw Blade shuts off automatically when cutting is complete.

• Low voltage & zero voltage controls.

• A blade breakage sensor / motion detector provides automatic shutoff.
