The deformation of thin plates is mainly caused by uneven heat input, which can be controlled by the following strategies:
Energy management: reduce power and increase speed. For example, 0.5mm stainless steel uses 800W power + 12m/min speed, combined with high-frequency pulses (2000Hz) to quickly dissipate heat.
Gas optimization: Use high-pressure air (0.8~1.2MPa) instead of nitrogen to enhance the cooling effect; for mirror stainless steel, the "dual gas path" function can be turned on, the upper gas purges the slag, and the lower gas cools the plate.
Auxiliary tooling: Use magnetic fixtures or vacuum adsorption tables to fix the plate to prevent warping. If processing long strip parts, keep micro-connection points (0.1~0.2mm) and break them manually after all cutting is completed.
Post-processing compensation: Preset the reverse deformation amount in the CAD design (such as adding 0.05mm arc for every 100mm length) to offset the thermal shrinkage effect.
Advanced solution: Introducing a water-cooled workbench (water temperature 10~15℃) can completely eliminate thermal deformation, but it requires customized equipment and control of condensation water risks.
