If a Milling Bit is stuck
If a
Milling Bit
is stuck in the
chuck
, the probable cause is low
air pressure
.
To release a
Milling Bit
from the
chuck
, a pressure of 7 bar is required.
If necessary, check the
Pressurized Air Regulator Valve
, or the
Pressurized Air
source.
If the bit is still stuck, see the
Chuck change and cleaning
section about how to unscrew the
chuck.
12.8.9. Chuck Change and Cleaning
Clean the
taper
and the
chuck
regularly for proper operation and optimum life time; at least
once a week, but more often if necessary.
Follow the procedure strictly.
Normally, the
chuck
has a long lifetime.
Extended vibrations or impacts may hurt the
chuck
, and cause bad milling results.
Trying a new
chuck
is the easiest way to identify if the
chuck
is the problem.
Running with a bad
chuck
will also increase the spindle wear.
