Scientific popularization of CNC lathe

It is the abbreviation of digital control machine tool. It is an automatic machine tool equipped with program control system. The control system can logically process the program specified by control code or other symbolic instructions and decode it, so as to make the machine tool act and process parts. The operation and monitoring of CNC machine tool are all completed in this CNC unit. It is the brain of CNC machine tool.

High machining precision and stable machining quality;

It can carry out multi coordinate linkage and process parts with complex shape;

When machining parts are changed, generally only the CNC program needs to be changed, which can save production preparation time;

The machine tool itself has high precision and rigidity, can choose favorable processing amount, and has high productivity (generally 3 ~ 5 times that of ordinary machine tools);

The machine tool has a high degree of automation, which can reduce the labor intensity;

Higher quality requirements for operators and higher technical requirements for maintenance personnel.

CNC machine tools are generally composed of the following parts:

Host is the main body of CNC machine tool, including machine tool body, column, spindle, feed mechanism and other mechanical parts. 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. It is used to input digital part program, complete input information storage, data transformation, interpolation operation and realize various control functions.

The driving device is the driving component of the actuator of the CNC machine tool, including the spindle driving unit, feed unit, spindle motor and feed motor. It realizes spindle and feed drive through electrical or electro-hydraulic servo system under the control of CNC device. When several feeds are linked, positioning, straight line, plane curve and space can be completed 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 devices, chip removal devices, exchange worktables, CNC turntables and CNC indexing heads, as well as cutting tools and monitoring and detection devices.

Programming and other auxiliary equipment can be used to program and store parts outside the machine.
