8.0 Maintenance
8.1 Preparation Before Maintenance
1. Understand the safety instructions in this manual.
2. Maintain the Vertical Machining Center correctly.
3. Understand the maintenance procedures in this manual.
4. Obey the maintenance procedures and complete the maintenance records after the
maintenance procedures have been done.
8.2 Centralized Lubrication System Maintenance
The operating conditions of the Machine depend heavily on maintenance of the centralized
lubrication system. Check the lubrication system regularly to keep the Machine in a good,
serviceable condition.
Regularly clean the oil tank of the centralized lubrication system. The oil tank will also require
cleaning if any impurity is found at the bottom of the tank or in the filter of the oil suction set.
To clean the oil tank:
1. Loosen the screws which secure the oil tank to the lubricator.
2. Separate the oil tank from the lubricator.
3. Clean the oil tank.
4. Tighten the screws to secure the oil tank to the lubricator.
Keep the oil level between high and low. If the oil level is less than low, the centralized
lubrication system will stop, and the alarm will sound or give a visual indication.
To fill the centralized lubrication system with oil, refer to Section 5.6.2.
The recommended lubrication oil to use in the pneumatic system, and the recommended
lubrication grease and cutting coolant to use are listed in the oil guide table, refer to
Section 8.3.4.
8.2.1 Warning System for the Centralized Lubrication System
The warning system is designed to inform users of when to check and fill up the slideway
lubrication system. When the warning alarm message shows on the control panel, fill the tank
immediately. The warning alarm will continue if the warning status is not stopped. Check the
centralized lubrication system weekly, and fill the tank if necessary. The recommended
lubrication oil is listed in the oil guide table, refer to
Section 8.3.4.
8.3 Lubrication
8.3.1 Lubrication for the X, Y and Z Axis Bearings
Lubricate the bearings of the X-axis, Y-axis or Z-axis with grease. The recommended grease
(Nbu 15) can be used in high temperature conditions and has a good lubrication property.
