Precautions for CNC machining should be kept in mind

CNC machining first appeared in Hong Kong. CNC and CNC machine tools are local names; Later, it was slowly introduced by the Pearl River Delta area in the mainland. The locals called it CNC car, milling, grinding machine processing, etc; It has been popular to the current CNC machining center. CNC machining is an automatic machine tool equipped with a program control system, which can logically process programs with control codes or other symbolic instructions and decode them through computers, so that the machine moves and processes parts. The blank is processed into semi-finished parts through tool cutting. The main reason why CNC machining is getting bigger and bigger is that CNC machining has the following advantages: advantage 1: The number of tooling is greatly reduced, and the parts with complex shapes do not need complicated tooling. If you want to change the shape and size of the parts, you only need to modify the parts processing program, which is suitable for new product development and modification; Advantages 2: stable processing quality, high processing precision, high repetition precision, and adapt to the processing requirements of the aircraft; Advantages 3: high production efficiency in 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 due to the use of the best cutting amount; Advantage 4: It can process geometric surfaces that are difficult to process by conventional methods, and even process some unobservable processing parts. Of course, after we know the advantages of CNC machining, we must also know that many manufacturers have high demand and are also very strict with CNC machining, and the matters needing attention are also essential. Precautions for CNC machining: Note 1: Before starting the machine, check the machine as a whole to ensure the safety and normal operation of the machine; Note 2: during the operation, the staff needs to strictly implement the operating procedures; Note 3: during the operation, do not chat with personnel or do other unrelated things to avoid accidents; Note 4: When the processing operation is completed, the processing site should be thoroughly cleaned, the processed residue should be cleaned and recovered, and the main switch of the machine tool should be turned off. In fact, CNC machining has both advantages and disadvantages. The main disadvantage of CNC machining is that machine tools and equipment are expensive and require maintenance personnel to have a high level.
