Start-up sequence: successively turn on the ventilation and dust removal equipment, main power supply, compressed air source, and finally start the sandblasting host,Parameter settings: Adjust the sandblasting pressure (usually 0.4-0.8MPa) according to the workpiece material, spray gun distance (recommended 15-30cm), and spray angle (vertical or 75°-90°),Operation monitoring:,Maintain uniform relative movement between the spray gun and the workpiece to ensure even coverage,Observe the air pressure and abrasive flow in real time, and stop immediately in case of abnormality,End operation: After the program is completed, turn off the spray gun, wait for the equipment to stabilize, then remove the workpiece and check the surface cleanliness and roughness
