4.1.8 DUAL ARM TOOL
CHANGER
The causes of abnormal wear and fractures will be apparent when the tool changer is
used without lubricant. It is very important to grease all moving parts of the tool changer
at least once a week.
Lubricant
The lubricant should be changed annually, or when it has become visibly deteriorated.
The recommended lubricant is SAE 90-140. The DATC uses approximately 5 liters of
lubricant (1.3 gallons).
Grease
Grease should be spread once a week in the following locations:
1. The claws of the tool changing arm unit.
2. The tip of the release pin of the tool changing arm unit.
Cleaning
1. Remove the chip powder from around the proximity switch inducing box.
2. Remove the chip powder from around the inverted moving body of the tool pot.
3. The tool changing mechanism must be cleaned frequently to prevent excess build
up of chip powder.
Inspection
Check the parts of the tool falling mechanism regularly and, check for grease on the
sliding base of the tool falling mechanism and the sliding base of the pull rod. Check the
parts of the tool pots and tool discs for tightness and overall condition.
