A fully automatic band saw of a double-column construction, designed also for double-sided mitre cuts. The outstanding cutting power of the machine results from the following features: a three-sided hardmetal band precision guide, a saw arm laid both-sided on preloaded linear guides, a 41 mm high saw band and lastly, a synchronous running brush for chips disposal. Material downfeed is controlled electromechanically, while material clamping and arm down- feed are controlled hydraulically.
The maximum length of an individual feed is 2,300 mm and may be extended up to 6,000 mm upon request. The whole work cycle is completed after the length and number of pieces and angles on each side of a piece have been programmed. The programming is performed in simple steps, and thanks to a large graphic display of individual sections it is easy to control for the user. After switching the machine to the manual mode, all functions of the machine may be controlled separately. All control elements are located on the freely-adjustable control panel. The angles are set electromechanically from 60° at the left to 60° at the right with ±0.1 ° precision.
Material clamping is performed by full-stroke vices. The machine is equipped with a frequency convertor that allows the saw band’s optimal speed to be set against the processed material within the 20–120 m/min range; this signi cantly increases both the saw band lifetime and the machine’s productivity. The saw band is tilted against the vice load surface at a 2° angle, which also significantly shortens cutting times and contributes to a longer saw band lifetime.
The standard equipment also includes automatic downfeed pressure regulation dependent on the resistance of the processed material, and continuously adjustable arm downfeed. Automatic material shape detection allows the saw arm to move with the maximum speed close above the material, which signi cantly shortens the cycle time. Thanks to its overall design this automatic machine is suitable for cutting pro le materials, especially in the range of frequent double-sided mitre cuts with single feed precision 0.2 mm.
