6.2 Service Procedures
Component replacement and adjustment procedures are provided in the following section.
CAUTION:
Thread locker applied to fasteners must not be used more than once.
Fasteners might become loose and cause equipment damage. Always apply new
thread locker when reusing fasteners.
6.2.1 Bur and Collet Replacement
In normal operation, the bur can become worn. If improper feeds and speeds are used, the bur
may become “loaded” with material. In both instances, the bur must be replaced. During initial
production, inspect the bur and the work piece often in order to determine when the bur needs to be
replaced. Replacing the collet is not required, when the bur is replaced, but a different collet may be
required, if a different sized bur is used.
The following steps detail replacing the bur and or collet:
Refer to
.
Parts required: Refer to
Tools required: 7/16” (11 mm) and ER‑11 (10 mm) open‑end (collet) wrench
1.
Remove and/or lock‑out the spindle motor air supply for safety.
2. If the bur is to be replaced with one of an identical type, measure and record the bur length
extending beyond the collet lock nut. Alternatively, the optional ATI 9150‑RC‑T‑4230 bur
setting tool accessory can be used to duplicate tool exposure length.
3.
Use the 7/16” open‑end wrench to hold the spindle behind the collet nut.
4.
Use the 10 mm collet wrench to turn the collet locknut counterclockwise (when viewed from
the bur tip) to loosen the collet.
CAUTION:
During operation of the deburring tool, the bur reaches high
temperatures. Failure to wear proper personal protection equipment or not
allowing the bur to cool could result in serious injury. Be aware that during
operation, the bur becomes very hot, and when removing the bur, take
necessary safety precautions to avoid injury.
5.
To remove a worn bur, pull the bur out of the loosened collet.
6.
If the collet is being replaced, completely remove the nut and extract the old collet. Insert the
new collet and install the nut leaving it loose.
7.
If an identical new bur is replacing a worn one, insert the new bur, measure, and adjust the
length of its exposed portion according to the measurement taken in Step
8. Use the 7/16” open‑end wrench to hold the spindle behind the collet nut.
9.
Use the 10 mm collet wrench to turn the collet locknut clockwise (when viewed from the bur
tip) to tighten the collet.
10. Restore the air supply.
