If you want to get this order for a precision CNC machining plant, you have to be more professional than the customer.
In this article, Longsheng technology will take you to deeply understand the secret of precision CNC machining technology, from the technical principle to the application range of comprehensive analysis, so that you have a deeper understanding of precision CNC machining.
Principle and characteristic of precision CNC machining
CNC machining is a kind of CNC machining technology based on computer control, its machining precision is high, high efficiency, has a strong flexibility and adaptability. CNC machining mainly relies on computer programs, the 3D model of the processing object into G code instructions, through the control of each part of the control system to achieve mechanical movement, so as to complete the machining object cutting, punching and other process operations. The basic principle of CNC machining is to control the action of the machine tool through the computer program, and in this way to control the relative movement of the workpiece in each dimension. Compared with traditional machining, CNC machining has the following significant characteristics:
With high precision and high efficiency. Because CNC machining using computer program control, can accurately control the position of the tool and cutting depth, so as to achieve high precision machining of the workpiece.
Remote monitoring and control: Because CNC machining needs the support of computer processing, so you can use remote monitoring and control, man-machine cooperation and automatic information collection.
Automated production without human involvement. CNC machining process is generally controlled by numerical control system operation, through the numerical controller to control the whole machine tool processing process, reduce manual intervention, improve production efficiency.
Flexibility and repeatability. CNC machining can carry out repeated processing, and will not affect the processing accuracy and efficiency because of the difference of people, fatigue and so on.
Ability to process on complex shape parts and products. Due to the support of computer programs, CNC machining can process a variety of complex shapes of parts and products, such as engraving, trapezoidal shape and so on, reducing the traditional processing technology is difficult to complete the work.
At the same time, CNC machining also has some limitations and shortcomings. Due to the limitations of equipment and technology, CNC machining needs to consume a lot of energy, materials and human input, the cost is relatively high. In addition, CNC machining requires a higher level of technology and professional knowledge, the technical requirements of the operator is higher, not easy to get started. Therefore, CNC machining is generally suitable for mass manufacturing and high precision processing fields.
