The basic principle of the Extend series of large machines is increased production through customization of the machines to the needs of the customer.
Thanks to a modular design with numerous configuration possibilities, coupled with heavy, reliable design, there is an Extend machine for every need.
As standard modules, feed lengths of 1500 mm and 3000 mm are available. The feed is mounted on linear guides that are adjusted without play. It moves electrically over a gear rack and a pre-stressed sprocket and is positioned with a linear measuring system over the entire length of the feed.
Inconspicuous but innovative details round out the Extend series' standard equipment. These include a custom-adjustable material removal slide and a hydraulic band tension display.
The simple, clear interface on the freely positionable control panel is equipped with a lighted, multi-line display and gives the operator status reports in plain text.
Highly precise carbide saw band guides, with acute sensors for automatic adjustment of cutting pressure on both guide arms, guarantee precise saw cuts and the longest possible blade life.

Bomar Extend 700.520 Technical Details
Powered shavings brush always runs synchronized to the saw band speed.
Precise and stable
On both columns, the saw frame is mounted to high-precision, play-free linear guides. These guides guarantee maximally smooth operation and cutting precision.
The vice is guided on hardened, ground rails. The special design allows the slide rails to be readjusted at any time and the vice to be held play-free.
Large guide shoes made of vibration-damping cast material in combination with carbide slideways and low-wear guide rollers make for precise cuts.
Generously sized full-lift cylinders allow vice operation right 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, and more.
Cutting feed and cutting pressure are set individually at the control panel. The selected cutting pressure is displayed on a manometer.
ADFR – The highest precision. Faster cut.
The ADFR system regulates the interplay of the cutting pressure and the cutting feed automatically in real time. A sensor gives the current load on the saw band and regulates the cutting feed according to the shape of the material. For larger cross cuts to the material, the cutting channel lengthens and the saw band's load increases. If the cutting feed in these ranges is not automatically adjusted, the saw band's life drastically decreases or the cutting time significantly drops due to a lower feed.
