GENERAL INSTRUCTIONS
TABLE FEED HANDWHEEL
T h e table feed handwheel is the large hand-
wheel on the left front of the machine. O n e com-
plete revolution of this handwheel moves the table
3-½".
Moving the handwheel transmits motion through
the table feed rack pinion to the table rack which
is fastened to the underside of the table. To dis-
engage the table feed rack pinion from the table
rack, pull handwheel outward. While in this out-
ward position, the handwheel can be turned with-
out moving the table. This will enable you to place
the handwheel handle in a convenient position for
handling the desired stroke for the work you are
grinding.
AUXILIARY TABLE FEED
(RAPID TRAVERSE LEVER)
Machines equipped with auxiliary table feed
have the auxiliary table feed lever located at the
e x t r e m e left of the cross feed carriage. W h e n not
in use, auxiliary feed lever should be in down
position. To move lever to this position, pull out-
ward, swing to the left and down 180°. To utilize
this lever, center the part which you intend to
grind under grinding wheel, disengage table feed
handwheel. To retain handwheel in disengaged
position turn handwheel until handle is in up posi-
tion, pull handwheel outward as far as possible,
and turn 180°, placing handle in down position.
Move auxiliary table feed lever to a vertical posi-
tion allowing the gear to engage the rack of the
table. T h e auxiliary table feed is designed for fast
and accurate grinding of work up to 6" in length.
CROSS FEED TABLE CARRIAGE
T h e cross feed table carriage travels on two
ground and scraped fiat ways. It is guided and
held in perfect alignment by a hardened and ground
rectangular shaped key which is mounted in the
center on the underside of the carriage. This rec-
tangular shaped key moves between a stationary
gib on its left side and a set of tapered adjusting
gibs on its right side. T h e gibs have been properly
adjusted for a snug sliding fit at the factory but
should the necessity arise for readjustment, they
may be adjusted by means of the screw mounted
on the base and located just right of the rectangular
shaped key.
CROSS FEED TABLE CARRIAGE LOCK
T h i s machine is equipped with a device for
locking the table carriage in position when face
grinding. You will find the cross feed table lock
thumb screw located on the right hand side of the
base directly under the table cross feed carriage.
Tightening this thumb screw locks the adjusting
gibs up against the cross feed table key, prevent-
ing transverse movement.
I M P O R T A N T : T h i s lock must be released
when operating the machine under normal con-
ditions.
CROSS FEED HANDWHEEL
T h e cross feed handwheel is located in the
center on the front of the machine. It is graduated
to (.001"). O n e complete turn will move the cross
feed table carriage (.100"). T h i s wheel controls
the transverse movement of the cross feed table
carriage.
ELEVATING HANDWHEEL
T h e elevating handwheel located at the top of
the column on the right side is used to raise or
lower the spindle. It is graduated in one half thou-
sandths (.0005"). O n e complete revolution raises
or lowers the spindle (.050").
If the elevating handwheel rotates too freely, it
can be adjusted for the proper rotating tension by
means of the tension adjusting device designed for
this purpose. To gain access to this adjustment
remove the (4) flat head screws securing the
column cover to the column. J u s t to the rear and
right of the handwheel, you will find the socket
head adjusting screw. To increase the tension on
the handwheel turn clockwise. To decrease the
tension turn counter clockwise.
VERTICAL FEED GEARS
Remove cover from top of the vertical column.
T h e pinion is secured to elevating handwheel shaft
just below the bevel gear and backlash is adjusted
by means of a locking collar.
