There are significant differences between machining and CNC Machining in many aspects, and the following is a detailed comparison of the two: Definition and Principle of 1. 1. Machining: Machining refers to the process of changing the external dimensions or performance of the workpiece through mechanical equipment. It uses lathes, milling machines, drilling machines and other mechanical equipment for processing, and can manufacture parts and components of various shapes and specifications. 2.CNC machining: CNC machining, that is, computer numerical control machining, is an important part of modern manufacturing technology. It uses a computer program to control the machine tool for precise processing, which can process parts with complex shapes and high precision. 2. operation mode Machining: Machining mainly relies on workers to manually operate machine tools and tools to complete processing tasks. Workers need to have a high level of technology and rich experience, the operation process is relatively cumbersome and the technical requirements of workers are high. 2.CNC machining: CNC machining to achieve a high degree of automation and intelligence. Workers only need to write a good processing program, the machine tool can automatically complete the processing process according to the program. This mode of operation greatly improves the processing efficiency and accuracy, and reduces the labor intensity of workers. 3. machining accuracy and stability 1. Machining: The machining accuracy and stability of machining are affected by many factors such as the technical level of workers, operating experience and machine tool accuracy. Therefore, its processing accuracy and stability are relatively low. 2.CNC machining: CNC machining has higher machining accuracy and stability. CNC Machine Tools can accurately control the tool trajectory and cutting parameters in the machining process, so as to achieve high-precision machining. At the same time, because most of the operations are automatically completed by the machine, the repeatability of the processing quality is also higher. 4. processing range and adaptability 1. Machining: Machining is limited by machine tools and tools, and the processing range is relatively narrow. For parts with complex shapes or high precision requirements, machining may be difficult. 2.CNC machining: CNC machining has a wider range of processing. CNC machine tools can adapt to the processing needs of different materials and shapes by changing tools and fixtures, and realize the processing of a variety of complex parts. At the same time, CNC machining also has a high adaptability, can easily switch the processing object, shorten the production preparation cycle.
