The operation and monitoring of CNC machine tools are all completed in this CNC unit, which is the brain of CNC machine tools.
Compared with ordinary machine tools, CNC machine tools have the following characteristics: computer gong processing, Dongguan computer gong processing, high-speed computer gong processing, mechanical parts processing, computer gong processing
High machining precision and stable machining quality;
It can carry out multi coordinate linkage and process parts with complex shapes;
When the processing parts are changed, the CNC program only needs to be changed to save the production preparation time;
The machine tool itself has high precision and rigidity. It can choose favorable processing amount and high productivity (generally 3 ~ 5 times of ordinary machine tool);
High degree of automation of machine tools can reduce labor intensity;
The requirements for the quality of operators are higher, and the technical requirements for maintenance personnel are higher.
CNC machine tools are generally composed of the following parts:
The main engine is the theme of CNC machine tools, including machine body, column, spindle, feed mechanism and other mechanical components. It is a mechanical part used to complete various cutting processes.
CNC device is the core of CNC machine tool, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and corresponding software for inputting digital part program, Dongguan computer gong processing, high-speed computer gong processing, mechanical parts processing, computer gong processing, etc The transformation, interpolation and Realization of various control functions.
Drive device, which is the driving component of the executive mechanism of CNC machine tool, including spindle drive unit, feed unit, spindle motor and feed motor, etc. Under the control of the numerical control device, he realizes the spindle and feed drive through the electric or electro-hydraulic servo system. When several feed linkage, positioning, straight line, plane curve and space curve processing can be completed.
Auxiliary device, some necessary matching parts of index control machine tool, to ensure the operation of CNC machine tool, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal device, exchange table, CNC turntable and CNC dividing head, as well as cutting tools and monitoring and detecting devices.
Programming and other auxiliary equipment can be used to program and store parts outside the machine.
Since the first CNC machine tool was developed by Massachusetts Institute of technology in 1952, CNC machine tools have been widely used in manufacturing industry, such as computer gong processing, Dongguan computer gong processing, high-speed computer gong processing, mechanical parts processing, computer gong processing, especially in automobile, aerospace and military industries. Numerical control technology has been rapidly applied in both hardware and software development.
