LVD Strippit has expanded its PPEC series of midrange, precision hydraulic press brakes to offer machines up to 700 tons. The higher-tonnage models provide heavier forming capacity and expand the line with machines from 39 tons in bend lengths up to 265 in.
The machines are equipped with the company's CADMAN® Lite control, which offers 2-D graphic programming with automatic collision detection, direct angle input or quick bend programming, and connection with CADMAN-B offline programming software.
Models up to 350 tons feature a welded, one-piece frame machined without repositioning. Hydraulic cylinders are machined from a solid steel billet. Pistons are steel forgings, precision ground and micropolished.
Microprocessor technology is linked to servo-controlled hydraulics and electronics to control the bending process. Double bed-referenced encoders are connected to the bed so that deformation of the side frames during bending does not influence the positioning accuracy of 0.0004 in. of the upper beam (Y1-Y2).
