1. Water cooled spindle
If your machine uses a water-cooled spindle, you should ensure to clean the water and the pump. The water cooled spindle must absolutely be used with water. The cooling water temperature should be < 35 degrees, it’s advised to check the water temperature during processing to prevent high temperature to lead to spindle overheating.
2. Keep clean
After each use of the machine, be sure to clean the dust on the platform and drive unit. Use compressed air to blow dust out of the control box (Do not use brushes or any other tools which could produce electrostatic electricity), check the screws of the wire plugs to ensure an optimal contact.
3. Lubrication weekly
Lubricate the rails and ball screws weekly with special grease for rails. If you do not have access to it in you local market, you can use high-speed bearing grease (lithium grease, white, suitable temperature: -20 °C ~ 120 °C).
If you plan on not using the machine for a long time, ensure to take dust and water proof precautions. Make the machine idle for at least half an hour per week to ensure the flexibility of the transmission system.
5. Flat & stable desk
The engraving machine must be placed on a solid and heavy desk, the desktop must be flat. we suggest placing a steel plate on the desk, uneven desktop will cause deformation of the machines underpan.
6. Loose trailing cables
Check the cable line of the drag chain at least one time per month, and loosen the tight cable line in time, so as to ensure that each line in the drag chain is loose. At the time of engraving, these cable lines need to do flexing operations repeatedly, so if the line is tight, it may easily lead to breaking of internal copper wires, thus causing poor contact. This may cause the electric motor to run out of control.
