3-7-7 Backlash eliminator
The use of the backlash eliminator device allows “climb milling” to be carried out on this
machine. The backlash eliminator controller (8) (Fig. 5) is situated on the front of the
saddle. When climb milling is to take place with the cutter revolving clockwise and the
table moving from right to left, the backlash eliminator control should be rotated counter –
clockwise.
To set the backlash eliminator turn the controller (8) (Fig. 5) in the appropriate direction
and at the same time rotate the table hand wheel. Continue turning the controller (8) (Fig. 5)
until resistance is felt at the table hand wheel.
Do not over tighten the backlash eliminator.
The table must not be put into rapid traverse when the backlash eliminator is engaged.
3-7-8 Operation of dog
The auto-stop longitudinal feed is worked by dogs which are located in the T-slot front of
table. The two fixed dogs (2) (3) (Fig. 8) on the outsides are safety stops which prevent
over travel. These should not be moved.
The two inside dogs (4) (5) (Fig. 8) can be set at any position so that the table stops
automatically in set range.
