Advantages and disadvantages of CNC machining

Advantages of CNC machining:

① The number of tooling is greatly reduced, and complex tooling is not required for machining parts with complex shape. If you want to change the shape and size of parts, you only need to modify the part processing program, which is suitable for new product development and modification.

② CNC machining has stable quality, high machining precision and high repetition precision, which can meet the machining requirements of precision robots and high-end automation equipment.

③ Under the condition of multiple varieties and small batch production, CNC numerical control machining has high production efficiency, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of z-best cutting quantity.

④ It can process complex surfaces that are difficult to be processed by conventional methods, and even process some unobservable machining parts by CNC.

Disadvantages of CNC machining:

1) High processing cost

not bad Among many parts processing technologies, CNC processing should be one of the most expensive processes.

2) Long processing time

CNC processing cycle is long, which is well known. When the machining design of CNC parts has special requirements (such as precision tolerance requirements and thin-wall design), special tools, more precise quality control, lower machining speed and more complex machining steps are required, which will seriously affect the time.

3) High equipment maintenance cost

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