This automatic bandsaw of a double-column construction, de- signed for perpendicular cuts of materials up to 350 mm in diameter, provides high quality at an affordable price. The saw arm is guided by two robust columns and laid on preloaded, no-clearance linear guiding on one side and on auxiliary guiding on the other side. The excellent cutting per- formance results from these features: a three-sided hardmetal precision guide, 34 mm high saw band, and synchronous run- ning brush for chips removal. Material feed under the band, material clamping, and arm downfeed are controlled hydraulically.
The maximum length of an individual feed is 600 mm. Data are entered via an easy-to-control membrane keyboard and display. The programming is performed in simple steps, and thanks to a graphic display of individual sections it is easy to control for the user. After switching the machine to the manual mode, all functions may be controlled separately. All control elements are located on the freely-adjustable control panel.
Material clamping is performed by full-stroke vices. The machine is equipped with a frequency convertor that allows the band’s optimal speed to be set against the processed material within the 20-120 m/min range; this significantly increases both the saw band lifetime and the machine productivity. The band is tilted against the vice load surface at 2° angle, which significantly reduces cutting times and contributes to a longer saw band lifetime.
Thanks to their arms rigidity, double-column bandsaws with a fixed arm position achieve much shorter cutting times (especially in cutting full materials) than machines with articulated saw arms.
