Closed mechanical CNC turret

Closed Mechanical CNC Turret Punching Machine

Closed Mechanical CNC Turret Punching Machine

1. Introduction of closed mechanical CNC turret punching machine:

  • Punching processing and shallow drawing forming processing on the plate;
  • Composed of computer control system; mechanical power system; servo feeding mechanism; die library; die selection system; peripheral programming system and so on.
  • Can be customized according to the requirement of the customer, such as: nominal pressure; color; working stations; throat depth; and so on.

Working principle:

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

2. 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, hardware, all kinds of metal plates, boxes, cabinets and other industries. This type CNC punching machine especially suit for many varieties middle or small batch plate processing.

3. Main features:

          

  •  Closed "O" design structure, high strength 30mm thick carbon steel welded rack, after integral tempering treatment, with stable performance.
  •  Lengthened beam (3700mm) can conveniently processing large plate, and enhancing the stability.
  •  The turrets are processed by special fixture in pairs; thick ductile iron turret (up: 80mm; down: 70mm), using internationally general type long oriented die.
  •  Large power imported Panasonic servo motor to ensure the feeding precision.
  •  Taiwan imported wide seating linear guide rail and large ball screw to ensure the processing accuracy.
  •  Using well-known brands pneumatic components and electrical components to ensure the service life.
  •  The transmission adopts gear box which equipped with three stage gear transmission.
  •  Brush and universal ball mixed work table.
  •  Equipped with centralized automatic lubrication device.
  •  Using 3 sets full floating clamps.
  •  Adopts lateral positioning technology to avoid the deformation caused by the end face positioning.
  •  Dedicated CNC software using mature configurations (well known brands integral industrial controller and motion control card) with powerful functions such as: protection; automatic positioning; graphic conversion; mold management; graphic dialog programming; one- button operation; failure alarm; and so on.
  •  Unique assembly process, such as the 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; and so on.
  •  Strictly quality control measure, such as: 
  1.  The turret can be assembled after inspection qualified by the "three coordinate measuring instrument".
  2.  Linear guide rail, ball screw can be assembled by using laser collimator.
  3.  All of welding and casting parts can be assembled after tempering and inspecting.
  4.  All machining parts are completed by machining center and after inspecting; and so on.
