CNC Guillotine Shear Machine 6×3200 with Front Feeding

6x3200 CNC hydraulic guillotine Shearing machine

Long plate like 3m or 2.5m thin plate is difficult to hold by people. CNC Guillotine Shear Machine with front CNC feeding will be the selection. The plate will be hold by pneumatic clamps and move over rolling-ball table. The shearing machine can be equiped with swing beam type or guillotine type. there is no back gauge. CNC controller control feeding positioning from front. rear side can be with plate collection carriage or table as customer self design. Guillotine shear's cutting angle is adjustable from 0.5~2 degree. small angle is suitable for thin plate cutting, less edge twist.

TECHNICAL FEATURES

  • Complete machine includes CNC Guillotine Shear Machine and CNC controled Front feeding unit;
  • CNC feeding unit is driven by high efficient ball screw and liner guide; servo motor Directly drive;
  • Pneumatic clamps will hold the sheet metal and move accurately according CNC guillotine shear machine controller’s program;
  • CNC Guillotine Shear Machine plus CNC feeding will realise one time plate install and automatic finish sheet cutting function. It will efficiently reduce human operation. Plate cutting accurate is high.
  • CNC controller can be DELEM DAC310, DAC360, ESTUN E21, JINQIU DTC660 professional for CNC Guillotine Shear Machine;
  • CNC Guillotine Shear Machine’s hydraulic cylinder is connected in series. cutting angle is adjustable. smaller cutting angle can reduce sheet edge twist. bigger cutting angle can cut big thickness;
  • Both UP and down blades of CNC Guillotine Shear Machine have 4-cutting edge; blades life is longer;
  • Shearing blades material can be 6CrW2Si for mild steel or H13 / 12CrMoV for harder sheet metal;
  • Front feeding CNC Guillotine Shear Machine has no back gauge.
  • CNC controller can control front gauge, shearing rake angle, cutting length;
  • Rear side of CNC Guillotine Shear Machine can be optional equipped with pneumatic following support. It means during cutting, the rear support will follow sheet cutting. It will reduce plate curve or hurt.

  1. How to adjust CNC Guillotine Shear Machine blades gap?

    To cut metal sheet , we shall set proper up / down blades gap. The proper shear blades gap will affect on cutting force and plate cutting edge. For low elongation metal plate, we shall use smaller gap.
    CNC Guillotine Shear Machine Blade 

    GAP = K * t (plate thickness)

    • Mild steel (Q235, Q345): K = 0.1
    • Stainless steel (201, 304, 316):  K = 0.06~0.08
    • AL, copper : K = 0.6
    • Weldox (700, 900, 960): K = 0.12~0.16
    • Hardox (400 ): K = 0.16~0.18

    NOTE:  

    1. After first cutting, we shall check cutting edge performance. We may need to increase or decrease to improve edge performance.
    2. For Harder plate material, we shall use high chrome and harder shear blades, like Cr12MoV, H13;
    3. For harder material cutting, we shall use higher capacity shearing machine. The cutting force can be 2 times than mild steel for SS plate, Or even more for other harder plate. We shall keep blades edge sharp during cutting.
    4. For Hydraulic Plate Shear, we can directly adjust blades gap on CNC controller. while for manual metal plate shear, we can adjust blades gap by adjust handle manually.
  2. How to adjust CNC Guillotine Shear Machine cutting angle / rake angle?
    • Only Hydraulic guillotine type Hydraulic Sheet Shearing Machine’s cutting angle is adjustable. For swing beam shear, top beam shearing angle is fixed.
    • Hydraulic guillotine shear’s cylinders are connected in series. It means big cylinder down chamber is connected with small cylinder’s top chamber by hydraulic pipe or hose.  Increase or decrease oil volume can adjust small cylinder’s relative position of small cylinder. so that we can adjust shearing angle.
    • On control panel, turn the key switch to angle, push increase or decrease button to adjust shearing angle.
    • For thin plate, smaller shearing angle can reduce edge twist. For bigger thickness plate, bigger shearing angle can reduce cutting force needed.
  3. How to Exchange CNC Guillotine Shear Machine blades and how to sharp blades edge?
    • For Hydraulic guillotine shear, top/down blades has 4 cutting edge. for swing beam type shear, top blades have 2 cutting edge, bottom blades have 4 edge. we can directly take off blades and change cutting edge. Before use the machine, we shall make sure that the blades are fixed and gap even. otherwise, we may damage the blades.
    • When all blades edge is not blunt. We shall take off the blades complete (top / down). Put all same set blades over surface grinder to sharp them. we must make sure same set blades thickness is equal.
    • Shearing machine’s top blades are fixed by bolts only. bottom blades are fixed over square block. We must calibrate shearing gap before working. method is different for different model machine. consult our engineer for detail.
