Composition and structure of precision CNC lathe

Before using a precision CNC lathe, it is necessary to have a comprehensive understanding of its structure, working principle and operation precautions. Let's take a look at the composition and structure of precision CNC lathes.

1. Host: It is the main body of the precision CNC machine tool, including the machine tool body, column, spindle, feed mechanism and other mechanical components. It is a mechanical part used to complete various cutting processes.

2. Auxiliary device: Refers to some supporting components necessary for precision CNC machine tools to ensure the operation of CNC machine tools, such as cooling, chip removal, lubrication, lighting, monitoring, etc., including hydraulic and pneumatic devices, chip removal devices, exchange tables, and CNC turntables , CNC dividing head, etc., as well as cutting tools and monitoring and testing equipment.

3. Numerical control device: It is the core of CNC machine tools, including hardware (printed circuit board, CRT display, key box, tape reader, etc.) and corresponding software. It is used to input digital part programs, complete input information storage, data conversion, interpolation calculation, and realize various control functions.

4. Driving device: the drive of the actuator of the precision CNC machine tool, including the spindle drive unit, feed unit, spindle motor and feed motor. Under the control of the numerical control device, the spindle and feed drive are realized through the electro-hydraulic servo system. When multiple feeds are connected, the processing of positioning, straight line, plane curve and space curve can be completed.

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