Presa hidraulica CNC - PP 250/4200 CNC

• Accurate positioning and repetability performance of synchronized CNC brakes
• Calibration of cylinder axes and back gauge axes, maintained by automatic indexing at the start of machine
• Calculation and performing of below facilities: - determination of bending force necessary of bending stroke - Inspection on display, of potential interference between machine, tools and parts before and after each bend - automatic positioning of the backgauge for each step of the bending program - calculation of bottom and top dead centre for accurate bending a - storage and recalling of bending tools - programming of bending speeds - selection of manual, semi-automatic and automatic working modes
• Welded steel construction of monobloc frame
• Bend performing by down strocking beam
• Cylinders made from high quality forged steel
• Pistons hardened, chrome plated and ground precisely
• Hardened ram slideways working with low friction and wear resistant material and optimum lubrication grooves
• CNC controlled backgauge with ballscrews spindles, ball guides and AC or DC servomotors
• Compact Rexroth hydraulic blocks
• Full electronic synchronization with proportional valve technology.
