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).

4. Idling

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.

For a water-cooled spindle, we need to use correct ways to maintain it.
1. The cooling water, you can choose either tap water or deionized water. Please add a little common antirust into water ( the kind used in water tank of cars is OK).

2. You need to ensure that the spindle runs normally, so that you must avoid the water-cooled spindle lacks water. During operation, please check the surface temperature of the spindle regularly to prevent from a hot spindle.

3. Please measure the temperature of the cooling water periodically, you’d better keep the cooling water within 30 degree centigrade. When the environment temperature is high ( in summer), please use a big-size water tank. When the temperature of the cooling water is rising, you can lower the temperature by adding more water.

4. If you use tap water, please change the water periodically ( change one time in a week)

5. When the temperature in winter is below 5 degree centigrade, please add some anti-freezing solution into the cooling water.

6. If you don’t use the machine for a long time, you must use compressed air to blow out the water in the spindle until there is no water in it.
