Extend 620.620 SX is fully hydraulic semiautomatic double column band saw. The band saw is designed for cutting both full and also pro led material at an angle of 90°. 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.
The pedestal, frame and pillars in all of the Extend Series machines are lled with a polymer-concrete mixture developed by our company. In connection with preloaded, largely over-dimensioned guiding, the polymer-concrete technology allows the machine to perform cuts with almost no vibration and with cutting speed more than 100 cm2 (with bi-metalic saw blade type M42). Clamping Vise is equipped with a large, massively dimensioned full-stroke hydraulic cylinder and can be tted by pressure control for sensitive setting maximum clamping pressure on request.
Movable clamping jaw is guided on rails hardened wear resistant. The machine is equipped with a frequency converter, which enables to set the optimum speed of the blade in the range from 15 to 90 m / min. This significantly increases both blade life and machine productivity.
Extend SX Series machines deliver innovative controls that allow seamless expansion functions with regard to the customer’s requirements. This means that the Extend SX machines are ideal for customized cutting lines.
The machine can be used in semi-automatic mode, but also machine can be switched to manual mode where all functions of the machine may be controlled separately. Machine control is provided by simple text messages on large LCD. Display is placed on the freely- adjustable control panel. The standard equipment also includes automatic downfeed pressure regulation dependent on the resistance of the processed material, and continuously adjustable arm downfeed.
The saw band is tilted against the vice load surface at a 2° angle for universal usage. Upon request, the arm may be tilted at 6° for an even shorter cutting groove in pro les and supports which substantially shortens cutting times and contributes to a longer lifetime of the saw band. Alternatively, the arm need not be tilted at all (0°) for processing full material.
