• Twin column design; heavy duty construction, bow running on linear bearings
• Downfeed; automatic regulation of saw bow descent responding to variable material mass
• Controls; machine functions housed in seperate moveable pedestal, fault diagnosis, machine status reports displayed on large LCD.

Bomar Extend Range Technical Details

Synchronisation
Powered swarf brush always runs synchronised to the saw blade speed.

Precise and stable
Both columns, the machine base and the bow are filled with polymer concrete to absorb vibrations during the cutting process. The saw frame is mounted to high-precision, play-free linear guides. These guides guarantee maximally smooth operation and cutting precision.

Precision
Large tungsten carbide pads fitted to vibration-damping cast material and low-wear rollers guide the blade perfectly for precise and accurate cuts.

Full length cylinders
Generously sized full stroke cylinders allow the vice clamping and unclamping operation from the control panel.

Saw band tensioner
Standard equipment includes a hydraulic band tension display, an electronic monitor for saw blade tension and saw band breakage.

AFDR (Automatic Down Feed Regulation)
Cutting feed and cutting pressure are set individually at the control panel. The selected cutting pressure is displayed on a gauge.

The ADFR system regulates the cutting pressure and the cutting feed rate automatically in real time. A sensor gives the current load on the blade and regulates the cutting feed according to the shape and cross section of the material. For larger cross cuts, the cutting channel lengthens and the saw band's load increases which activates the ADFR valves to reduce the downfeed rate automatically. If the cutting feed in these ranges is not automatically adjusted, blade life drastically decreases and/or accuracy is lost!
