MEGA AUTOMATIC HORIZONTAL BANDSAWS 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 nine strokes 144 "

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

Features
PRECISE CUT OFF LENGTH SETTING:
A convenient digital readout control located at the operator's station provides easy selection of precise bar length requirement. The digital readout is calibrated in 0.10 mm or 0.01 IN increments and can be repositioned without interrupting the cutting cycle.

AUTO HEAD-ELEVATION AND QUICK APPROACH:
Raising the blade higher than necessary to clear the work for the next cut wastes time Head elevation is controlled automatically and no longer requires the operator's attention. A control device that senses the size of the workpiece permits the saw head to raise just high enough so the blade clears the work. This reduces index cycling time significantly.

NESTING FIXTURE:
The hydraulically operated nesting fixture is designed for high-production multiple sawing of stacked bars. small rounds and tubing. The fixture contains vertical cyinders mounted on the index and front vises. lt holds stacked work firmly to assure accurate cuts and prevent center bars from turning.

CUTTING PIECE COUNTER AND MULTIPLE STROKE COUNTER:
The cutting piece counter is used to preset the number of cuts required on automatic operation. When the counter reaches the preset number the saw automatically stops. The multiple stroke counter makes it possible to multiply the number of index cycles when pieces longer than 400 mm (16 in.) are required

QUICK-ADJUSTING CARBIDE BLADE GUIDES:
For the replacement of the saw blade or the repositioning of the guide arms. two levers are incorporated in the saw guides to allow these operations to be carried out quickly and efficiently. (standard on 460/550 models) (optional on other models)
QUICK ADJUSTING CARBIDE GUIDES
IDLE WHEEL MOTION DETECTOR:
The device not only can protect the saw blade from damage if the blade overloads during cutting. but will also shutoff the machine if the blade should break.

HYDRAULIC BAND TENSION CONTROL:
During operation of the saw, the correct tension is automatically maintained. the tension is reduced when the saw is shut-off This procedure greatly increases blade life.

QUICK-ACTION HYDRAULIC TWIN-VICE (SPLIT VICE)3-JAW CLAMPING:
Materials are firmly clamped on both sides of the saw blade by twin vices. Operating a single switch provides manual or automatic clamping and unclamping materials. These unique twin vices allow automatic bar feed and cutting to within as little as 50 mm of bar end

UNIQUE TWO-WAY VISE JAW:
Both vise jaws on the rear work-carriage are actuated simultaneously, opening or closing, instead of the traditional one that is fixed on one side, moveable on another. This particular design ensures accurate indexing even with warped stock.
