Inserting tooling
The Model 1230 uses a #4 Morse taper in the
spindle to secure tooling. Any drill, milling cutter, or
tool holder with a #4MT can be inserted into the quill.
Caution
The first step in removing or inserting any
tooling is to be absolutely certain the machine
cannot be accidentally started during the insertion
or removal operation. The only way to be certain
of this fact is to disconnect power to the machine
using the service box cut-out switch. The service
box (typically the one holding the fuses or circuit
breakers will have been installed by the electrician
who connected the machine to its service branch)
should have a cut-out switch or lever on the outside
of the box. Put the switch or lever in the OFF
position before inserting or removing tooling.
To insert tooling:
1. Observe the caution, above, and be certain all
power to the machine has been disconnected.
2. Be certain the spindle is clean, free from oil, and
ready to accept the shank of any tooling.
3. Check the shank of the tooling to be certain the
tooling is free from dirt, nicks or burrs. If any nicks
or burrs are discovered, file and/or stone the shank
until the shank is smooth.
4. Be certain the quill is in the full UP position.
5. Slide the shank of the tooling into the spindle until
it seats.
6. Use a soft-faced mallet (such as lead, plastic,
brass, etc.) to give the tooling a sharp tap on its tip.
This will secure the tooling firmly in the taper.
7. Re-establish power to the machine and the drill is
ready to use.
To remove tooling:
1. Observe the caution above and be certain all
electrical power to the drill press has been cut off.
2. Place a wood block under the tooling in the
spindle to prevent it from being damaged, should it
fall out of the quill during the removal process.
3. Lower the quill by using the feed levers until the
tool removal window is exposed.
4. Using a suitable tapered drift, insert the drift in
the removal window, above the tip of the tooling
shank.
5. Using leather gloves to prevent cuts from the
tooling, hold the tooling with you hand to prevent it
from falling from the quill.
6. With your free hand, using a hammer, tap the
tapered drift and the tooling will loosen from the taper
and can be removed. The spindle is now ready for
the insertion of other tooling with a #4 MT.
Positioning the tooling over the
workpiece.
After the workpiece has been clamped to the
base or table you can position the tooling over the
workpiece by doing any or all of the following:
1. Adjusting the height of the arm on the support
column.
2. Moving the drill head along the arm.
3. Rotating the column upon which the arm and head
are attached.
Unlocking the arm and column
mechanisms
A motorized locking system is used to lock the
head to the arm, the arm to the column, and the
column to the base.
The lock and unlock buttons which control the
locks are located on the right-hand side of the drill
head. When you push UNLOCK, all of the locks are
unlocked. When you push LOCK, all of the locks are
locked.
Caution
Always be certain the locks are engaged before
using the drill press. Pull on the arm handle and
try to rotate the head locating wheel before
pushing the spindle ON button. Failure to have
all locks locked may result in damage to tooling,
damage to the work piece, and possible injury to
the operator.
Raising and lowering the radial arm
1. Power to the drill press must be ON -- then release
the machine locks by pushing the UNLOCK push
button.
2. Use the control lever -- push it upward or down-
ward as required -- (see Fig. 3) to raise or lower the
arm to the required height. See also,
Using the
control lever
.
3. When the arm is at the required height and if no
other adjustments to spindle location are required,
push the LOCK push button to re-lock all machine
locks.
To move the drill head along the arm
1. Power to the drill press must be ON -- then release
the machine locks by pushing the UNLOCK push
button.
2. Using the wheel in the center of the drill head, turn
the wheel to move the drill head along the arm. (See
Fig. 1.)
3. When the drill head is at the desired position on
the arm and if no other adjustments to spindle location
are required, push the LOCK push button to re-lock all
machine locks.
