Band Saws

Extend 1000.820 A 1500/2500

Extend 1000.820 A 1500/2500

An automatic band saw of a double-column construction, designed for perpendicular cuts of full, as well as pro le materials. The outstand- ing 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 54 mm high saw band and lastly, a synchronous running brush for chips disposal. The pedestal, frame and pillars in all 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 vibrations. Material downfeed is controlled electrome- chanically, while material clamping and arm downfeed are controlled hydraulically. The maximum length of an individual feed is 1,500 mm or 2,500 mm. The whole work cycle is completed after the length and number of pieces 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.

All control elements are located on the freely-adjustable control panel. Machine control system is from prestigious company B&R. Machine control is via the touch screen and separate mechanical buttons for each machinefunction. After switch- ing the machine to the semiautomatic mode, all functions of the machine may be controlled separately. Material clamping is performed by full stroke vices. The machine is equipped with a frequency convertor that allows the saw band optimal speed to be set against the processed material within the 15–90 m/min range; this signi cantly increases both the saw band lifetime and the machine’s productivity.

Standard equipment also includes automatic downfeed pressure regulation depending 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, which substantially shortens cutting times and contributes to a longer lifetime of the saw band. Machine can be extended by handlig systems and cross conveyer units.

Extend A is basic for a completely unattended automatic and personalized customer cutting line.

Suitable handling systems

Handling System X/XP

The new X/XP handling system offers unprecedented flexibility for tailoring a handling system to individual needs and conditions. Load capacities and automation levels can be adjusted with perfect flexibility and modified at a later time. Besides the roll conveyor in a regular and propelled version, the X system comprises a rich array of options, from vertical rollers, to length measuring systems all the way to cross conveyor units and shifting devices. The load capacity can be customized by the number of rollers and support feet used. The roll conveyor's feed profile even allows varying roller and foot distances on the same roll conveyor unit. When needed, additional rollers and/or support feet can be installed at any time.
