CNC Brake Press Machine 400T

250T NC hydraulic press brake machine

Some customer call any machine with programable controller CNC machine. Ok, Let's call this machine CNC Brake Press Machine 400T. Machine is with 2-axis (X, Y) CNC control. While as manufacture, we would like call torsion bar structure press brake NC type. It is just to identify Electric-hydraulic synchro press brake. 400T-3.2m, 4m, 6m machines are big capacity, suitable for big thickness metal plate bending. We would like suggest this machine with NC or CNC controlled. Because target plate is heavy and large. Control system can make people operate more easier and effective.

TECHNICAL FEATURES

  • The CNC Brake Press Machine is C-Frame type Press Brake. High quality plate welded structure; with vibration stress released will make machine high rigidity and long working life.
  • NC controller can be with AC inverter motors or servo motors to control back gauge and bending depth / bending angle;
  • CNC Brake Press Machine Back gauge is with Ball screw and liner guide; positioning and repeat accuracy is higher;
  • The ram is down stroke type; two cylinders transfer bending force;
  • The bending beam / ram is with High wear-resistant polymer guide. It will make CNC Brake Press Machine ram move smooth and accurate bending;
  • Two side cylinders are hydraulic-mechanic synchronized. Solid torsion bar will make CNC Brake Press Machine bending under good parallelism and bending accurate;
  • Hydraulic cylinder has built-in mechanic stop. Two cylinders mechanic stops are synchronized by synchro-shaft and gear system. It will make cylinders work at same bending depth;
  • Our engineer designed CNC Brake Press machine open height, throat depth and cylinder stroke according to general sheet metal fabrication. Which is our standard machine parameters listed. We also can make according to customer special requirements;
  • At side of CNC Brake Press Machine, remote hydraulic pressure gauge and adjust handle will make machine bending pressure adjust more easy.
  • Electric and hydraulic systems are with internal overload protection;
  • At side of CNC Brake Press Machine, stroke adjustment structure will control ram top stop position, approaching to working speed change point. Ram working will have fast down, working, holding and return.
  • Hydraulic system is with low noise accurate gear pump, compact hydraulic valve block. Which will make   CNC hydraulic press brake machine easy hydraulic maintenance.400t-NC hydraulic bending press brake wc67k
  • Movable foot switch with protection and emergency stop;
  • Welded back gauge beam has high rigidity and accuracy; we also can supply nice looking aluminum back gauge; two adjustable stop fingers;
  • Standard machine is with two front support arms; The arms are mounted in T-slot of working table, vertical-horizontal adjustable. The arms are with ruler and stopper for simple bending option;
  • Standard hydraulic punch and multi-V bottom die is equipped;
  • CNC Brake Press Machine Oil tank is with level and temperature indicator.
