During the operation of a CNC lathe, the protection of the machine tool itself is particularly crucial, as it not only significantly impacts the machining accuracy of workpieces but also plays a vital role in the longevity of the machine tool. Today, Haishu Machinery, a CNC lathe manufacturer, will explain the three major protection mechanisms in the operation of the lathe body.
1. Regular Maintenance and Precision Inspection:
       Geometric accuracy: Regularly use laser interferometers, ballbar instruments, and other devices to inspect the machine tool's positioning accuracy, repeatability, backlash, spindle radial/axial runout, guide rail straightness, etc. Calibration is performed through parameters such as pitch compensation and backlash compensation.   

Maintenance: Strictly implement lubrication, cleaning, and rust prevention maintenance to ensure the proper condition of moving parts such as guide rails, lead screws, and bearings.
2. Control thermal deformation:
       Preheating: Conduct an empty run preheating before processing (especially for the spindle and feed axes) to achieve thermal equilibrium in the machine tool.
       Ambient temperature: Maintain a constant workshop temperature (e.g., 20°C ± 1°C), avoiding direct sunlight and air flow disturbances.
       Cooling: Ensure the cooling systems for key components such as the spindle, lead screw, and motor are functioning properly.
3. Suppress vibration:
       Foundation: The machine tool is installed on a stable, vibration-proof foundation.
       Dynamic balancing: The spindle, chuck, and workpiece (especially large or irregular workpieces) must undergo proper dynamic balancing.
       Stiffness: Ensure the machine tool-jig-tool-workpiece system has sufficient stiffness.
The above are the three major protection mechanisms for the operation of the lathe body, compiled and published by Haisun Machinery, our CNC lathe manufacturer. We hope the following explanations will be of some help to you in operating CNC lathes in the future.
