CNC machining refers to a process method for machining parts on CNC machine tools. The process rules of CNC machine tool machining and traditional machine tool machining are generally consistent, but there have also been significant changes.
What is the value of CNC machining?
What is the machining process of CNC machining?
What are the precautions for CNC machining?
With the development of science and technology, people's requirements for the quality of parts machining are becoming more and more demanding. At the same time, the product is frequently formed, in the general mechanical processing, single pieces and small and medium series products occupy an increasing proportion. In order to ensure product quality, increase productivity and reduce costs, machine tools are required to have higher versatility and flexibility, as well as a high degree of automation in machining. CNC machining technology developed in this environment is a digital information control by CNC machine tools, which is suitable for high-precision, complex molded parts of individual and small and medium-sized production of efficient, flexible automated processing technology.
The CNC machining process is the operator first according to the processing drawings becomes the content of the manufacturing process, and is familiar with the processing process based on the preparation of processing procedures with the prescribed code and program format for the human will into the CNC machine tool can accept the information. The information is recorded on the control media (such as perforated tapes, tapes or plates and other information input media), so that it becomes the control of the machine tool commands. After processing the input information, the CNC control unit sends command pulses to the servo system of each axis of the machine tool to drive the corresponding moving parts of the machine tool and control the speed change, tool change and other actions such as opening and closing the machine tool automatically machining the workpiece to meet the requirements of the drawing.
1. CNC machining should allow the tool to complete the machining of a part or a work shift as much as possible. When finishing large parts, special care should be taken to avoid changing tools in the middle to ensure that the tool can be machined all at once;
2. use higher speed as much as possible when turning threads with CNC lathes to achieve high quality and efficient production.
3. the basic concept of high-speed CNC machining is that the feed rate exceeds the heat conduction speed, so that the cutting heat is dissipated with the iron filings to isolate the cutting heat from the workpiece and ensure that the workpiece does not heat up or heats up less. Therefore, high-speed machining is selected. The cutting speed is adjusted to the high feed rate, and a low backcut is selected.
Guangdong Fenghua Zhuoli Technology Co, Ltd (stock code: 834914, initials: FHZL) is the pioneer leading the commercialization of sand mold 3D printing technology in China. The technology originated from Professor Yan Yongnian of Qsinghua University, the first person to conduct research and development in sand mold 3D printing in China.
