Toolpost overrun/gearbox protection device
Fig. 24
The toolpost overrun and gearbox protection device is designed to stop the
toolpost leadscrew nut jamming against a fixed surfacing arm end plate and thus
damaging the feed gearbox. When the feed nut comes into contact with the end
plate
it will push the plate along its mounting studs. Should the operator fail to
notice his error eventually the plate will fall off.
The toolpost and machine will still operate correctly without the end plate but if it is
not replaced the cast iron dovetail slideway may be damaged.
To replace the end plate:
8. Remove the two end plate mounting studs
from the end of the surfacing arm.
9. Push the mounting stud through the star washer with the concave side facing
the thread.
10. Position the end plate and screw the studs back into the slideway.
POSITION THE ENDPLATE SUCH THAT THAT THE STAR WASHERS WILL
LOCATE AGAINST THE FLAT SURFACE OF THE ENDPLATE – NOT INTO THE
COUNTER BORED HOLES.
11. The toolpost and gearbox protection device is now correctly assembled.
FAILURE TO FIT THE STAR WASHER THE CORRECT WAY AROUND WILL
RESULT IN DAMAGE TO THE FEED GEARBOX.
