SPINDLE MOTOR-OIL PUMP
The spindle motor is turned on by momentarily turning the “Spindle” button towards the ON
position. This also starts the oil pump of the lubricating system. After ½ minute the oil level
should rise to the mid-point of the sight glass in the column cap of the machine. The spindle and
oil pump are stopped by momentarily turning the “Spindle” button towards the OFF position, or
pressing the “Emergency Stop” button. (Pressing the emergency stop button will also stop the
hydraulic and cross feed system motors if they are running.)
MACHINE OPERATION- POWER ON
Turn the main switch clockwise to apply power to machine. (Be sure the “Emergency Stop”
buttons are not illuminated.)
LONGITUDINAL FEED
Warning:
When first starting the table to run automatically, make certain the proximity sensors
are between trip dogs. To connect the powered longitudinal feed, crank the table to right as far as
it will go. Bring the locking lever
(Fig. 4, A)
forward and down into the pilot nut on the end of
the cylinder rod. Be sure the lever is seated all the way into the groove. Adjust the two dogs
(Fig.
5, C)
to within a few inches less than the desired table travel. Turn the hydraulic button towards
the ON position. Disengage the handwheel by loosening the thumb screw
(Fig.4, B)
on the left
side of cross travel saddle and pull the longitudinal feed handwheel out about 1-1/4 inches
(Fig.5, A).
Momentarily turn the “Table” button towards the ON position
. (The handwheel
electrically locks out the hydraulic feed when engaged.)
Once the table is started, the control
will keep track of directions and reversals until the main disconnect is turned off, even if the
proximity switch is tripped while moving the table manually. The table will now power feed
(back and forth)
at a speed determined by the speed control knob.
(Fig. 5, B).
The maximum
feed rate will be 70 feet per minute. Turning the knob clockwise reduces the feed rate. When
grinding a piece at the full length of the chuck it may be necessary to readjust the table reversing
dogs, to prevent the table from hitting the internal table stop. To convert grinder back to hand
feed, stop the table by momentarily turning the “Table” button towards the OFF position. Turn
off the hydraulic system by momentarily turning the “Hydraulic” button towards the OFF
position. Re-engage handwheel. Crank table to right until the table hits the internal stop. Lift up
the locking lever (
Fig. 4, A
) to clear the pin and flip it back to its disengage position.
Note:
The speed control valve should be rotated fully counterclockwise in order to permit
manual movement of the table via the longitudinal feed handwheel. It is a good practice to
distribute oil evenly over entire length of ways before using grinder. Simply turn on spindle and
run table back and forth a few times. (The “Spindle” control activates oil pump.)
