2) Guide way Lubrication
Guide ways of the workbench (X-axis), the saddle (Y-axis), the head (Z-axis), ball screws of the three
axes (X, Y and Z axes) and the nuts are lubricated by the automatic centralized lubrication system in
which an oil pump is located at the back of the machine.
If the machine has not been operated for a long time, less lube oil will be available in the oil tube. For
the following cases:
1) A machine installed for the first time;
2) A machine has not been operated for a long time;
3) Before operating a machine (daily);
You should manually lubricate to ensure that sufficient lube oil has circulated the entire guide way.
Press the red button on the lube oil pump for about 40 sec before releasing the button. Wait for 10
sec to repeat the above procedure. Repeat this process until lube oil has leaked out from the guide
way.
Cautions
：
The oil tank has a 6-L capacity. Add oil from the oil inlet each week (or when necessary). If the oil
level reaches the minimum oil level, the operation panel will issue an alarm message informing the
risk.
1) Add clean lube oil specified for the guide way through the oil inlet. Do not use other types of lube
oil.
The recommended oils are:
Mobil VACTRA
1
Shell TONNA T32
2) Lube oil level:
The level should be maintained between the maximum and the minimum oil level marked on the oil
tank. Once the level drops below the midpoint, add oil as soon as possible. Do not add oil only after
the alarm goes off, which can affect the operation of the machine.
