DURMA SB 3020 hydraulic guillotine shears

DURMA SB 3020 hydraulic guillotine shears built in 2008 in Turkey are an ideal choice for machining stainless steel, copper, aluminium and plain steel. Workpieces with a maximum thickness of 20 mm are cut using extremely precise, hardened cutting knives with manual adjustment of the gap between the blades. The high-quality monoblock design, combined with the hydraulic system, additionally ensures the highest stability and machining performance, even during the most demanding challenges.

To facilitate the operator’s work, special transport rollers have been integrated into the work table, on which the workpiece is fed directly under the cutting line. The machining parameters are programmed in the intuitive DURMA ENC 100M control panel with clear LCD display and memory for 50 programs. The DURMA SB 3020 guillotine shears also features a driven back stop with T-slots and sockets with double beams, which can be adjusted from 0 to 1000 mm with an accuracy of 0.1 mm. The entire back stop working area is protected by LEUZE ELECTRONIC light curtains, which automatically switch off the machine’s power supply if the laser beam is interrupted.

Distinguished by its high performance, the hydraulic system consists of REXROTH components, smoothed cylinders, chrome-plated and precision-ground pistons and MERKEL seals. By using a small number of pipes and fittings in the hydraulic blocks, the system achieves maximum durability and ensures maximum service life. In addition, the hydraulic system is equipped with a 25 μ filter on the suction side and the return lines. The DURMA guillotine shears weigh 21480 kg.
