Overview:

  • Punching processing and shallow drawing forming processing can be done by it.
  • Composed of computer control system; mechanical power system; servo feeding mechanism; die library(turret) and selection system; peripheral programming system and so on.
  • Can be customized, such as :nominal pressure; throat depth; workstations quantity; color; etc.,

Work principle:     

      Closed type mechancial CNC turret punching machine by the programming software (or manual) processing program; by the servo feeding mechanism sent the plate to the required processing position; at the same time, by the die selection system choose the appropriate die from the turret; by the mechanical system according to the procedure of punching; automatic completion of the work piece processing.

Advantages:

  • High processing precision; stable processing quality; (punching accuracy:+-0.1mm; repeat positioning accuracy:+-0.02mm)

Various shape complex parts and shallow drawing forming process such as louver; shallow deep hole; flanging hole; reinforcing rib; stamping; shallow bending; forming; etc., can be done through adjustment the die and appropriate multi die linkage.

  • Fast processing speed; high productivity
  • With high degree of automation, can greatly reduce the labor intensity.

​Application:

  • Various shapes and sizes holes and parts can be processed by using the way of single punching or step punching.
  • Widely used in punching processing machinery; electrical appliances; instruments; screens (meshs); hardware; all kinds of metal plates; boxes; cabinets; and other industries.
  • Very suit for batch plate processing.

Main parts features:

  • Unique design and technologyconnect with the crossbeam as a whole, with super stability.
  • Lenghten crossbeam(up to 3700mm)
  • Worktable:

  • Brush and univerball mixed worktable.
  • Auto-indexs:

  • Auto index adopts turbine worm transmission mode with good stability and high accuracy.
  • With the features of high transmission ratio; good self locking; eliminating backlash;high precision indexing; easy to adjust and do not bite die.
  • Automatic lubrication device:

  • Pneumatic device:

  • Control cabinet:

  • Semi product view:

  • Unique assembly process:
  • Grinding on both bottom of the turret to ensure the smoothness of the surface;
  • Liquid nitrogen cooling treatment to installation the cone pin;
  • The turrets are processed by special fixture in pairs;
  • The turret can be assembled after inspection qualified by the "three coordinate measuring instrument";
  • Linear guide rail and ballscrew can be assembled by laser collimator;
  • All of welding and casting parts can be assembled after tempering and inspecting;
  • All machining parts are completed by machining center and after inspecting
