VM Series Maintenance and Safety Manual 704-0212-209 Machine Maintenance 3- 9
Automatic Tool Changer
The lubrication required depends upon the type of ATC. Refer to Lubrication, on page 3 -
5 for a list of recommended lubricants. Please refer to Automatic Tool Changer, on page 1
- 35 for information about each machine’s ATC taper size and number of tool pockets.
Tool changers have an enclosed oil lubrication system. The tool changer housing holds the
oil, some of which is displaced into a small oil reservoir during the tool change cycle.
Maintain the Tool Changer Indexer Oil Level
Every 3 Months or after 500 hours of operation: Check the ATC oil level.
Observe the oil level in the reservoir cup, located on the front of the tool changer (viewed
from the front of the machine). The oil level should always be in the middle of the round
sight glass.
If the oil level is low, add the recommended type. Refer to Table 3–1.Lubrication, on page
3 - 5 for recommended lubricants.
Replace the Tool Changer Oil
Annually or after 2000 hours: Replace the ATC oil.
1. Open the drain plug located near the bottom of the swing arm transmission
casting, or the cup inside the cover of the tool changer. Drain the oil.
2. Flush the system. Use a non-volatile flushing agent that is suitable for a
mineral-type lubricating system.
3. Replace the drain plug.
4. Add the new oil.
Grease the ATC Magazine Chain
Every 6 Months or every 1000 hours: Grease the ATC magazine chain assembly
Use a brush to apply grease. Spread a light coating of grease over the chain assembly.
Avoid grease build-up.
The oil should be changed more often than annually if it appears to
be darkening.
These machine models use ATC Magazine Chains: VM machines with
20-station ATCs, VMX machines with 24-station ATCs, and machines
with 40-station ATCs and larger.
