1. Improve the layout and structural design of CNC lathes: If the thermal symmetrical structure is more symmetrically used for thermal source; the CNC lathe uses a tilt bed, flat bed body, and oblique sliding plate structure; some heavy CNC machine tools adopt thermal balance measures due to structured restrictions.
2. Control the temperature rise: The heat of the CNC lathe (such as the main axis box, the hydraulic oil, etc. of the static pressure guide rail) adopt the control of heat dissipation, air -cooled and cold to absorb the heat from the heat source. Use a lot of countermeasures to reduce the effects of thermal deformation.
3. Take strong cold measures for the cutting site: When cutting the amount of large cutting, the hot source of the hot dandruff on the workbench, bed body and other components is an important heat source. Modern CNC machine tools, especially car milling, conform to the machining center and CNC lathes, generally use multi -nozzle, large flow coolant to cool and exclude these hot dandruff, and control the cooling liquid with large capacity or cooling with coolant with cooling. Warm rise.
4. heat displacement compensation: predict the law of heat deformation, and establish a mathematical model and deposit in the computer for real -time compensation.
