What is CNC Turret Punch Press Machine

CNC turret punch (NCT) is composed of computer control system, mechanical or hydraulic power system, servo feeding mechanism, mold library, mold selection system, peripheral programming system, etc.  

CNC turret punch (NCT) is through programming software (or manual) preparation of the processing program, the servo feeding mechanism will be sent to the plate to the position of processing, at the same time by the mold selection system to select the corresponding mold in the mold library, hydraulic power system according to the program to stamping, automatic completion of the workpiece processing.

The throat depth of CNC turret punch (NCT) is the distance from the punching center to the side plate of the bed.  The size of throat depth directly determines the width size of the processed sheet (that is, the size of the sheet processed along the length of the bed)

Processing method

1) Single punching: punching in a single time, including linear distribution, circular distribution, circular distribution, grid hole stamping.  

2) the same direction of continuous blanking: the use of rectangular mold overlapped processing way, can process long holes, cutting edges, etc..  

3) multi-direction continuous blanking: the use of small die processing large hole processing.  

4) Nibbling: the use of small round die in a small step for continuous punching arc processing.  

5) Single forming: according to the mold shape of a shallow deep drawing molding processing mode.  

6) continuous forming: forming larger than the mold size of the molding process, such as large shutter, rolling ribs, rolling steps and other processing methods.  

7) Array forming: processing multiple pieces of the same or different workpiece processing methods on the large plate.

The general thick turret mold can be classified according to the aperture size of the mold, which is convenient for the selection of the mold.  Usually divided into A, B, C, D, E five grades.  

A(1/2 ") position: Processing range Ø  1.6 ~ & Oslash;  The 12.7 mm  

B(1-1/2 ") position: processing range Ø  12.7 ~ & Oslash;  The 31.7 mm  

C(2 ") position: Processing range Ø  31.7 ~ & Oslash;  The 50.8 mm  

D(3-1/2 ") station: Processing range Ø  50.8 ~ & Oslash;  The 88.9 mm  

E(4-1/2 ") station: Processing range Ø  88.9 ~ & Oslash;  The 114.3 mm

Widely used in machinery, electrical appliances, instruments, screens, hardware, all kinds of metal plates, boxes, cabinets and other industries of stamping processing, the use of single punching mode and step punching mode out of various shapes, sizes of holes and parts, especially suitable for many varieties of medium and small batch or single sheet stamping.
