Advantages and disadvantages of CNC machining

Advantages and disadvantages of CNC machining

CNC machining has the following advantages:

① The number of tooling is greatly reduced, and complex tooling is not required for parts with complex processing forms. If we want to change the form and size of the parts, we only need to modify the processing program of the parts, which can be used in the development and modification of new products.

② The machining quality is stable, the machining precision is high, and the repeated precision is high, which is suitable for the machining requirements of aircraft.

③ Under the condition of multi type and small batch production, the production efficiency is high, which can reduce the time of production planning, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.

④ It can be used to process complex surfaces which are difficult to be processed by conventional methods, and even to process some processing parts which cannot be observed. The disadvantage of NC machining is the high cost of machine tools and equipment, which requires high level of maintenance staff.
