In modern improving industries the number of producers who decide on buying plate metal machine like CNC bend or CNC shear machine possessing smart CNC technique is increasing. CNC techniques vary according to standards and price. Choosing the right CNC technique will contribute to mass production process.

The following material is on press brake possessing CNC technique as a sample to support those producers who are interested in involving CNC technique in their manufacture process. Numerical control system is split up into

NC(Numerical Control) and CNC(Computer Numerical Control)

In case of the Numerical control the operation program is set by the producer and cannot be edited by the operator. In case of CNC the program may be modified in accordance with required specifications prior to operation.

To sum up NC is the older type of CNC technique and CNC is the advanced one.

And it is featured with the following priviliges:

First, CNC operates on the computer basis and it is quite simple to deal with and demands no special skills to run it. After a little practice operators get its working principles and take on the work. Numerical technique requires operators to get each character of the device as well as perform proper operation of it.

Second, this technique allows various programming and the functions are possible to store. The scale of stored functions depends on the system capability. Let us view ESA S500 controller on CNC bend device. More than 2 million programs are possible to be stored in a hard disk of 20 GB as well as more than 50 thousand programs may be stored on 256M U disk

In case there is a need to manage work pieces through a more complex manufacture, CNC system is more suitable. 

DCS(Digital control system) possesses no storing capability.

Work pieces obtained through CNC bend machine are more advanced and of greater accuracy than objects obtained through digital control technique.

As operation is managed by a computer, workers perform operations for quite shorter time, besides the system allows a 24-hour functioning for the machine.

So CNC bend devices possessing CNC technique are more advantageous, but they cost higher than NC bends. CNC technique is more valuable in terms of productivity. CNC system meets various requirements of customers, allows highly precise and excellent operation. 

Press brakes with CNC system are also featured with greater advantages and can serve ongoing production development needs.
