What is a CNC punch press? Literal understanding: digital control punch. What is the number? That is, a string of command code, which is commonly used in our computer programming code. The official explanation is that CNC punching machine is an automatic punch with program control system. The control system can logically process the program with control code or other symbol instructions, and decode it, so that the punch moves and processes parts.
 
The core position of CNC punching machine is called NC unit in some places. CNC. The narrow sense of the CNC system is to provide users with interactive interface, location control function unit. It contains three parts, the MMI (Man Machine Interface) man-machine interaction unit, the NCK (Numerical Control Kernel) NC core unit and the PLC (Programmable Logic Controller) programmable controller. NCK is the core part of CNC. The parsing of G code and the implementation of interpolation algorithm are all done in NCK. The role of PLC in CNC is mainly to control the tool changing of the punch, spindle speed and other servo control can not be achieved, and play a supporting role. In fact, PLC itself is quite a computer, and can also achieve motion control function. However, NCK+ servo motor can control motion better in CNC punch press, so PLC generally does not participate in motion control.
 
The CNC punch press is usually made up of the following parts:
Host machine, he is the theme of CNC punching machine, including punch body, column, spindle, feed mechanism and other mechanical components. He is used to complete various cutting parts.
 
Numerical control device is the core of the CNC punch press, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and corresponding software, which is used to input digital parts program, and the storage of input information, data transformation, interpolation operation and various control functions.
 
Drive device, which is the driving part of CNC punch press actuator, including spindle drive unit, feed unit, spindle motor and feed motor. Under the control of the numerical control device, he realizes the spindle and feed drive through electrical or electro hydraulic servo system. When several feed linkage is completed, positioning, straight line, plane curve and space curve can be completed.
 
Auxiliary equipment, some necessary components of the index punching machine to ensure the operation of the CNC punch press, such as cooling, chilling, lubrication, lighting, monitoring and so on. It includes hydraulic and pneumatic devices, chip removal device, exchange worktable, CNC turntable and CNC dividing head, and also includes cutting tools and monitoring and testing devices.
 
Programming and other ancillary equipment can be used for programming and storing parts outside the machine.
 
CNC punching machine can be used for all kinds of metal sheet parts processing, it can automatically complete a variety of complex holes and shallow drawing processing. (according to the requirements, different shapes of different sizes and holes are automatically machined, and the circular holes, square holes, waist shaped holes and various shapes can be made by the small punch die. Special processing can also be done, such as blinds, Asakura Nobu, countersink, flanging holes, stiffeners, embossing, etc.
 
Dadong CNC punching machine can be widely used in sheet metal processing, solar industry, building curtain wall decoration industry, electric box cabinet kitchen utensils, distribution boxes, grain machinery, elevator, ship industry, train, subway, high speed rail, aerospace, military industry, air conditioning, metal furniture, warehousing and logistics equipment, and other cold stamping processing fields.
 
Compared with the ordinary punch, the advantage of the CNC punch press is that a large amount of mold cost can be saved through a simple combination of die and mold. It can use low cost and short period to process small batch and diversified products, with large processing range and processing ability, so as to adapt to the change of market and product in time.
