Heat Treatment: 620°C in furnace for 5 hours, cooling to 300°C for 3 hours, then natural cooling to eliminate internal stress and prevent deformation.
Shot Blasting & Powder Coating: Removes surface oxides and improves appearance while increasing fatigue resistance and material life.
Precision Testing: Linear guide rails are tested for straightness and parallelism using precision instruments to ensure high running accuracy.
Laser Calibration: Final equipment precision is calibrated with a laser interferometer for maximum cutting accuracy.
