1. In addition to the backguage controled by CNC just as the usual swirling shear, the guillotine shears can control ram stroke, shearing angle, blade clearance, the number of workpieces are controlled accurately by Dutch Delem's DAC350 control system. 2. The automatic programming is carried out to adjust the shearing angle easily to reduce the workpiece deformation as a result of shearing plates of different length. 3. The sliding block stroke can also be adjusted automatically to realize fast and accurate shearing of short workpieces and improve productivity. 4. The shearing blades with four edges are made in Germany, featuring long service life, much longer than that of the shearing machine. 5. The high speed and large stroke backguage is made of the most advanced precision linear guide and ballscrew with its speed up to 200mm/s and the maximum rear stopping stroke up to 1000mm. 6. The system can automatically adjust the clearance between the upper and lower blades for different materials of different thickness to improve shearing quality. 7. The pneumatic rear support is optional for processing long and thin plates to improve the accuracy and reduce workload. 8. The integrated hydraulic system made by world famous manufacturers such as German Bosch is adopted to reduce piping connection, eliminate oil leakage, improve the work stability, and beautify the machine appearance.
