Use and Care Manual

5.4 X-Axis installation
Refer to Figure 5.
1. Move table to extreme left-hand position.
2. Remove jam nut, hand crank, dial nut, dial, dial
holder, bearing retainer ring, bearing flange,
etc.
3. Slide bushing onto lead screw.
4. Slide adaptor onto bushing.
5. Secure adaptor to the end of table with the
existing socket head cap screws.
6. Slide powerfeed onto bushing.
7. Secure powerfeed to adaptor using two socket
head cap screws provided.
5.4.1 Bevel gear
8. Remove protective cap from bevel gear, and
slide bevel gear onto lead screw. Manually
press and turn bevel gear against drive gear to
check for backlash, and make sure they mesh
snugly.
Leave the clearance between the two gears as
small as possible. If there is some clearance
left, place small shims one by one between
bearing and bevel gear until the gears are
properly fitted. Pack the gears with grease
before proceeding.
5.4.2 Dial and hand crank
9. After proper gear clearance has been set, slide
the dial into position to obtain 0.005” spacing
between dial and the face of the powerfeed
(this will prevent chips from entering gear
train.) Use the two solid and two laminated
large shims provided to accomplish the 0.005”
spacing. Use further shims if needed.
10. Install dial nut. Place key in shaft and install
hand crank. Add washer and locking nut, and
tighten locking nut.
5.4.3 Limit switch
11. Remove the standard travel stops from your
machine. Install the travel stops provided with
your powerfeed unit. It is important that these
stops be firmly secured in the table track to
prevent them from sliding loose and causing
the table to travel too far and possibly damage
other parts of the machine. It is recommended
that you either place the standard stops back
in position to block the new travel stops from
sliding; or drill a hole behind the table edge
and insert a screw through the travel stops
from behind.
12. Loosen and remove the two socket head cap
screws holding the T-shaped table stop
bracket. NOTE: Retain this original bracket
should manual table movement ever be
needed again.
13. Place the limit switch over the holes and
secure with two 3/8x1” socket head cap
screws provided. See Figure 6. If the actuators
are not symmetrical, grind them to obtain the
proper position.
14. Secure limit switch cord using the provided
clamp. Attach it to the right-hand side of chip
scraper with the screw provided. See Figure 6.
Figure 6
Never change direction of
power feed movement while machine is
operating, or damage to gear may result. Turn
direction control handle to OFF position and
wait for machine to come to a complete stop
before reversing direction.
IMPORTANT: Installing more than one powerfeed
on your machine may reduce table travel. For
example, the track assembly for the Y-Axis
powerfeed will prohibit full travel of the longitudinal
table on which the X-Axis powerfeed is installed.
These considerations should be carefully made
before installing multiple powerfeeds.
5.5 Y-Axis installation
5.5.1 Y-Axis track
Drill and tap #10-24 holes in the right side of
machine base below the table, for mounting the T-
Way Track. See Figure 7.
Note: The limit switch mounting bracket provided
with your powerfeed is designed for most mounting
situations. However, the casting design of your
particular machine may require modifications to the
bracket system.
