CNC is also called computer gong, CNCCH or CNC machine tool. It is actually a name from Hong Kong. Later it was introduced to the Pearl River Delta in mainland China. It is actually a CNC milling machine. In Guangdong, Jiangsu, Zhejiang and Shanghai, some people call it "CNC machining center". It is a new type of processing technology. The main job is to prepare processing programs, that is, to convert the original manual work into computer programming. Of course, experience in manual processing is required
CNC advantages and disadvantages
CNC machining has the following advantages:
① The number of tooling is greatly reduced, and complex tooling is not required for processing parts with complex shapes. 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 The processing quality is stable, the processing precision is high, and the repeatability is high, adapting to the processing requirements of aircraft.
③ The production efficiency is high in the case of multi-variety and small batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and the cutting time is reduced due to the use of the optimal cutting amount.
④ It can process complex surfaces that are difficult to process with conventional methods, and can even process some processing parts that cannot be observed.
The disadvantage of CNC machining is that machine tools and equipment are expensive and require high-level maintenance personnel.
