Presa hidraulica - PP 80/4000

• The whole body is designed and built as a welded one piece frame and machined at one time on a moving column CNC machining centre 

• Hydraulic cylinders are machined from a solid steel billet and honed precisely
• Pistons steel forgings, hardened, chrome plated, precision ground and micropolished
• Compact hydraulic block with pressure relief valves for safety
• The torsion bar and stooper system inside cylinders enable parallel move of the top beam and accurate bend angle at both ends of the work piece
• Pre-fill valves enable top beam to approch the work piece rapidly, and return rapidly after bending
• Pressure switch limits bending force during bending and activate automatic return of top beam to top dead centre • High pressure and silent Rexroth hydraulic pumps

Standard Accessories

• Motorized cylinder stopper control system
• Motorized rigid backgauge (X axis) system with ball screw and special design guiding system with minimized lubrication
• Two laterally adjustable front support arms with slot for height adjustment and slot front stop.
