1. Improve the layout and structure design of the vertical car
If the heat source is more symmetrical, the thermal symmetry structure is adopted; the CNC vertical lathe adopts the inclined bed, flat bed and inclined slide structure; some heavy-duty CNC machine tools adopt thermal balance measures due to structural limitations.
2. Control temperature rise
The heating part of the vertical car (such as the headstock, hydrostatic guide rail hydraulic oil, etc.) adopts heat dissipation, air cooling and liquid cooling to control the temperature rise to absorb the heat emitted by the heat source. It is a kind of more used on various CNC machine tools. Measures to reduce the influence of thermal deformation.
3. Take strong cooling measures to the cutting part
When cutting a large amount of cutting, the amount of hot chips falling on the worktable, bed and other parts is an important heat source. Modern CNC machine tools, especially machining centers and CNC vertical lathes, generally use multi-nozzle, large-flow coolant to cool and remove these hot chips, and use large-capacity circulating heat to cool the coolant or use a cooling device to cool to control the temperature rise .
4. Thermal displacement compensation
Predict the law of thermal deformation, establish a mathematical model and store it in the computer for real-time compensation.
