The operation and monitoring of CNC machine tools in Dongguan CNC machining plant 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:
High machining accuracy and stable machining quality;
It can carry out multi coordinate linkage and process complex parts;
When the machining parts are changed, generally only the NC program needs to be changed, which can save the production preparation time;
The machine tool itself has high precision and high rigidity, and can select favorable processing amount, with high productivity (generally 3-5 times of that of ordinary machine tool);
High degree of automation of machine tool can reduce labor intensity;
Higher requirements for the quality of operators and higher technical requirements for maintenance personnel.
The CNC machine tools of Dongguan CNC plant are generally composed of the following parts:
Main machine, which is the theme of CNC machine tools, including machine body, column, spindle, feed mechanism and other mechanical parts. It is used to complete all kinds of cutting machine parts.
Numerical control device: it is the core of numerical control machine tool, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and corresponding software, which is used to input digital part program, complete input information storage, data transformation, interpolation operation and realize various control functions.
Drive device, which is the driving component of the actuator 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, can complete the positioning, straight line, plane curve and space curve processing.
Auxiliary device, some necessary supporting 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 device, chip removal device, exchange table, numerical control turntable, numerical control dividing head, cutting tool, monitoring and detection device, etc.
Precision parts processing programming and other ancillary equipment can be used to program and store parts outside the machine.
Since MIT developed the first CNC machine tool in the world in 1952, CNC machine tools have been widely used in manufacturing industry, especially in automobile, aerospace and military industry. CNC technology has developed rapidly both in hardware and software.
