8.3.2 Lubrication for the X, Y and Z Axis Ballscrews
The working table, saddle, and headstock travel along the X,Y, and Z directions. The X-axis, Y-
axis or Z-axis movement is driven by an AC servo motor through the connection of a coupling
and a ballscrew. The ballscrews are pre-tensioned and lubricated with oil to avoid positional
error which can result from thermal deformation.
8.3.3 Lubrication and Cooling of the Spindle System
1. Lubricate the spindle bearings with grease. The recommended grease (Nbu 15) can be
used in high temperature conditions and has a good lubrication property.
2. Maintain a sufficient lubrication oil cooling level in the cooling system. Fill the system if
necessary.
3. The spindle cooler (optional equipment) is used to cool the spindle bearing and protects
the spindle system from thermal deformation.
8.3.4 Oil Guide Table
Note - Use the recommended fluid listed in the Oil Guide Table.
8.4 Machine Maintenance
Switch off the main power switch, the power switch of the Machine panel and the main power
circuit breaker. Put ‘Under Maintenance. Do not touch any power switch’ warning signs in
visible locations before starting the maintenance.
8.4.1 Notices
1. Only qualified engineers are allowed to maintain or install the electrical equipment.
2. Do not remove or alter the over-travel limit switches and related mechanical components
without permission.
3. Use a ladder when working in a high place.
4. Make sure all appliances operate correctly.
8.4.2 Cleaning the Machine
1. Clean the anti-rust treatment on the contact surfaces of the moving machine parts with
suitable cleaning agent.
