cnc cutting has the following advantages:

(1) A large number of tooling is reduced, and complex tooling is not needed for processing complex shaped parts. If you want to change the shape and size of the parts, only need to modify the parts processing program, suitable for new product development and modification.

(2) Stable machining quality, high machining accuracy, high repetition accuracy, to meet the requirements of aircraft processing.

(3) The production efficiency is higher under the condition of multi-variety and small-batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time because of the use of the best cutting amount.

(4) It can process complex surface which is difficult to be processed by conventional methods, and even some parts which cannot be observed.

The disadvantage of NC machining is that the machine tool equipment is expensive and the maintenance personnel are required to have a higher level.
