CNC cutting of 304 stainless steel plates requires optimized parameters to minimize thermal deformation. High-precision plasma or laser cutting is recommended, with a cutting speed controlled between 60-150 m/min to avoid rough cuts caused by excessive speed or overheating expansion caused by insufficient speed. The 304 stainless steel plate should be fixed before cutting, using clamps to prevent vibration and ensure a stable cutting path. Speed reduction is particularly important in areas with sudden changes in curvature to prevent beveling defects.
Post-cutting treatment of 304 stainless steel plates is crucial for controlling deformation. A reverse compensation of 0.1 mm should be applied to counteract thermal shrinkage, which is especially effective for thicker plates. The cut edges should be deburred, and chemical treatment may be used to enhance corrosion resistance and improve overall quality. Regular equipment calibration and maintaining a stable cutting nozzle height can significantly improve long-term accuracy.
