Summary of basic knowledge of high precision CNC lathe

High rigidity CNC lathe is a precise, economical and practical machine tool, which is used in precision machining of automobile, petroleum and other industries. It can realize the machining of inner and outer circular surfaces of shafts, sleeves and discs, and taper threads.

The systematic mechanical related deviation of CNC lathe can be recorded by the system, but due to the environmental factors such as temperature or mechanical load, the deviation may still appear or increase in the subsequent use process. In these cases, different compensation functions can be provided. In order to obtain better machining effect, the measurement value obtained by actual position encoder (such as grating) or additional sensor is used to compensate the deviation.

Composition of high rigidity CNC lathe:

It is the main body of CNC machine tool, 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 is the core of numerical control lathe, including hardware (printed circuit board, CRT display, key box, tape reader, etc.) and corresponding software. It is used to input digital part program, and complete the input information storage, data transformation, interpolation operation and various control functions.

The driving device is the driving part of the actuator of CNC machine tool, including spindle driving unit, feed unit, spindle motor and feed motor. 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 lathe, to ensure the operation of CNC machine tools, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal devices, exchange table, CNC turntable and CNC indexing head, and also includes tools and monitoring and detection devices.

Structural features of high rigidity CNC lathe:

1. High precision, high efficiency and easy operation. Adopting the mode of double track average main track is more conducive to improving the rigidity and service life of the machine tool, and the rigidity of the machine tool is good.

2. The lathe is completely closed, without exposed pipeline, clean and beautiful.

3. The fast feed speed of servo motor can reach 20 m / min.

4. The lathe is equipped with hard limit, return to zero and other functional switches, which is safe and reliable.

5. The lubrication mode adopts the circulating uninterrupted oil supply, and the lubricating oil is recycled, which can not only improve the service life of the machine tool, but also save the cost of the lubricating oil.

The constant pursuit of high quality and rate of CNC lathe is the eternal theme and goal of the research of mechanical manufacturing industry, and the source of promoting the development of its technological equipment. Process requirements and changes are the basis and basis of technological innovation and reform of mechanical manufacturing process equipment.

The quality of high rigidity CNC lathes should also be strictly controlled. If the ordinary lathes and the lathes used for a long time are not reformed, and only the new CNC lathes are purchased, the equipment costs of many manufacturers will be increased. Therefore, it is the only way for the manufacturers to carry out the numerical control transformation of the ordinary lathe and the lathe that has been used for a long time.
