Precautions for the entire process of mold use and maintenance


Confirm that the parting surface is free of scratches (Ra≤0.8μm). Check that the ejector pin/slider moves smoothly (manual stroke test). Verify the patency of the cooling water channels (flow meter test, pressure drop ≤0.1MPa)

A detailed guide to CNC product usage precautions, covering key aspects such as equipment operation, maintenance, and safety regulations, to help ensure machining accuracy, extend equipment life, and ensure operational safety


Confirm that the power supply and pneumatic/hydraulic system are stable (voltage fluctuation ≤ ±10%). Check the lubrication status of the guide rails and lead screws, ensuring that there is sufficient lubricating oil (ISO VG32 or higher guide rail oil is recommended). Verify the rigidity of the fixture/tooling to avoid machining vibrations (torque wrench tightening and a bolt pre-tightening force error ≤ 5% are recommended).
