CNC hydraulic press brake machine

  General Characteristics

  . Accurate positioning and repetability performance of synchronized CNC press brakes, achieved by synchronizing the hydraulic cylinders with advanced CN control of proportional valves and use of optic linear scales.

  . Calibration of cylinder axes and back gauge axes, maintained by automatic indexing at the start of machine. 

  . Calculation and performing of below facilities after inputting date like material thickness, bend length,tool details to the CNC unit.

-determination of bending force necessary for bending stroke.

  Interferences between machine, tools and part before and after each bend on the graphical display.

-visual inspection of potential interferences between machine, tools and part before and after each bend on the graphical display

-determination of the practical bending sequence

-calculation of bottom dead centre for accurate bending angle and top dead centre

-storage and recalling of part programs 

-storage and recalling of bending tools

-programming of bending speeds

-selection of manual , semi-automatic or automatic working modes

-tilting of upper beam for conical bending 

  . Welded steel construction of mono block frame for minimum deflection during operation 

  . Bend performing by down stroking beam

  . Cylinders made from high quality forged steel and honed precisely

  . Pistons hardened, chrome plated and ground precisely.

  . Hardened ram slide ways working with low friction and wear resistant material and optimum lubrication grooves.

  . Full electronic synchronization with proportional valve technology assuring maximum bend accuracy and repetability through constant monitoring and correction of beam parallelism by a CNC system
