VM Series Maintenance and Safety Manual 704-0212-209 Machine Maintenance 3- 31
Clean the Trunnion Table
Daily, after every shift, or every 8 hours of Trunnion operation: Clean the Trunnion
table (if equipped).
Use flood coolant and a clean brush to remove chips from the Trunnion table. Use gentle
pressure while cleaning the table to retain table alignment.
Rotary-Axis Maintenance
The rotary-axis (i.e., C-axis) on the Trunnion table can be positioned 360° and becomes
the machining center’s fourth axis for part programming. The rotary axis has a separate
oil system to ensure adequate lubrication.
Maintain the Rotary-Axis Oil Level
Daily or after 8 hours of operation: Check the rotary-axis oil level (if equipped).
Follow these steps:
1. Move the rotary-axis to 0
°
(i.e., the table is in the horizontal position).
2. Check the oil level through the oil level sight gauge located on the front side of
the Trunnion table. The oil sight gauge should be half-filled with oil.
3. If the oil level is low, open the oil fill plug located on the top of the Trunnion
table and add clean oil until the level of oil in the sight gauge is half-filled (the
level of oil will cover the red dot in the sight gauge). See Lubrication, on page
3 - 5 for recommended oil types.
Replace the Rotary-Axis Oil
Annually or after 2000 hours of operation: Replace the rotary-axis oil (if equipped).
Follow these steps:
1. Move the rotary-axis to approximately 60
°, until the oil fill plug on the top of
the Trunnion table faces the bottom of the machining center.
2. Place a suitable container underneath the Trunnion table to collect the used oil.
3. Open the drain plug on the top of the Trunnion table and drain the used oil into
the container.
4. Close the oil drain plug.
5. Tilt the rotary axis to approximately 30
°, until the oil fill plug on the top of the
Trunnion table faces towards the back of the machining center.
Do not use compressed air to remove chips or dirt from the Trunnion
table. Air-blown water and chips may become lodged underneath
and cause damage to the Trunnion table.
The rotary-axis oil should be changed more often than annually if the
oil appears to be darkening.
