A beam saw is for stack cutting, not for one-off parts

Choose a beam saw when the workshop breaks down full boards in stacks to a repeating cutting list. On a beam saw the board stays on the table, a programmed pusher with clamps carries the stack to the cutting line, a pressure beam holds the stack down and the saw carriage travels through it. A sliding table panel saw asks the operator to carry every sheet past the blade; a beam saw asks the operator to load a stack and start the program. The three MIZRAK DRAGON beam saws on this page cut three or four chipboards in a single pass, so a beam saw earns its floor space where the same part list is repeated week after week.

Board size and stack height choose the model

Board size is the first filter. The DRAGON PE 383 is built around 3800 x 3800 mm boards; the DRAGON PE 420-4 and DRAGON PE 420-5 are built around 4200 x 4200 mm boards. Stack height is the second filter and the figure to convert into real panels: 54 mm on the DRAGON PE 383, which cuts three particle boards at once against nine clamps; 72 mm on the DRAGON PE 420-4, which holds four boards against eleven clamps and drives a 15 kW main saw at 6000 rpm; and 90 mm on the DRAGON PE 420-5, whose 15 kW main saw turns a diameter 400 x 4.4 mm blade at 2945 rpm. The smallest machine is not the least equipped – the DRAGON PE 383 is the only DRAGON here that adjusts its scoring saw automatically in both axes.

Power supply, floor space and extraction

A beam saw is a three-phase installation and is not offered in single phase. The DRAGON PE 420-5 is published at 40 kW, 400 V and 80 A, and the main saw on both 4200 mm models is 15 kW, so the supply cable and protection have to be planned before the machine arrives rather than after. Floor space is always larger than the machine: allow the cutting length plus the full pusher stroke behind the table, an offloading and stacking area in front of the cutting line, and access for a lifting table or forklift to place boards. Chip volume from a stacked cut is high, so a beam saw belongs on a central extraction or cyclone system taken from the blade hood and the pressure beam, not on a mobile chip collector.

What is quoted alongside the machine

Budget beyond the beam saw itself for main and scoring blades and their regrinding cycle, for a compressor sized to feed clamps and pressure beam continuously, for the cutting optimisation software listed with the DRAGON PE 420-4, and for delivery, positioning, commissioning and operator training. Board size, stack height, clamp count, software and the tooling package are the real price drivers, which is why each DRAGON beam saw is quoted rather than listed. Send the board sizes you buy, the thickest stack you need and the length and width of the intended floor area with the request, and the quotation can be built around the actual work.
