What is the core technology of the CNC lathe ?

CNC lathe , as a high-precision, efficient machine tool, its core technology involves many fields, such as numerical control system, mechanical transmission, precision control and so on. This paper will discuss the core technology of CNC lathe .

　  Numerical control system:

CNC system is one of the core technologies of CNC lathe. Numerical control system refers to the automatic scheduling of the movement of machine tools through computer control mode to realize the digital control of processing technology. The core technologies in the CNC system include the design of the CNC system, programming mode, and control algorithm.

　 The design and development of CNC system is the key of CNC lathe manufacturing. The design of numerical control system needs to consider the structure and characteristics of the machine tool itself, but also needs to combine the specificity of the actual processing process, to determine the appropriate control mode and algorithm. Now, generally using PC based on Windows operating system DOS system, or embedded system (such as CNC system board) to do CNC programming work.

   Mechanical drive:

Mechanical transmission is one of the key technologies of CNC lathe, which is characterized by high precision and high speed. Mechanical transmission includes the design and selection of various components, such as wire rod, ball wire rod, etc. As the main mechanical parts in the CNC system, these parts need high accuracy and reliable use. Silk rod is the basic component in mechanical transmission, and its composition can be regarded as the rod of spiral profile, which is used to transfer power and movement. The wire rod is generally composed of two parts: nut and wire rod. The wire rod transforms the power of rotating and linear machine tool.

  For the CNC lathe, an important part of the mechanical transmission is the spindle and its related mechanism. The spindle is the shaft responsible for rotating the fixture and the tool on the CNC lathe. It is an important part of the cutting tool, and the control of its speed and rotation direction is very key.

   Fine control

Precision control is also one of the core technologies of CNC lathe, including the control of machining quality, machining precision and other aspects. The goal of precision control is to improve the processing quality, reduce the processing cost, and improve the processing efficiency.

　 First of all, the shaft control of the CNC lathe is usually carried out in a closed loop control ring environment. The hardware of the shaft control board and the software design of the system are very critical, because the stability of this board, response speed and other aspects will directly affect the processing effect of the lathe. Especially in the modern industrial application, the precision requirement of the processing workpiece is getting higher and higher, so the technical research in the precision control is becoming more and more in-depth.

Secondly, for some parameters that need to be controlled, such as the temperature generated in the processing process, it can also be monitored and controlled in real time through sensors. In this way, the heating and cooling in the processing process can meet the requirements respectively, facilitating the diversification of processing.
