What are the advantages and disadvantages of CNC machining?
Posted by Admin
CNC machining has the following advantages: ① The number of tooling is greatly reduced, and complex tooling is not required to process parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.
②The CNC machining quality is stable, the machining accuracy is high, and the repeatability is high, which is suitable for the machining requirements of precision robots and high-end automation equipment.
③ CNC machining has high production efficiency in the case of multi-variety and small batch production, which can reduce the time for production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.
④ It can process complex profiles that are difficult to process by conventional methods, and even CNC process some unobservable processing parts.
CNC machining has the following disadvantages: 1) High processing cost good! Among the many parts processing processes, CNC machining should be one of the most expensive processes.
2) Long processing time CNC machining cycle is long, which is well known. When CNC part machining design has special requirements (such as close tolerance requirements and thin wall design), special tools, more precise quality control, lower processing speed, and more complex processing steps are required, which can seriously affect the time. .
3) Equipment maintenance costs are high The disadvantage of CNC machining is that the machine tool is expensive and requires a high level of maintenance personnel.
