DRILL PRESS OPERATIONS
Familiarize yourself with all operating controls before
attempting use of this machine.
CONTROLS (see Figure 10)
1. The spindle (A) in this machine is either a No. 2
Morse Taper or a No. 33 taper type equipped with a
chuck. The key type chuck is 1/2" capacity, held to
the spindle by the taper and a threaded lock collar.
2. A depth stop rod (B) is provided to control hole
depth and to prevent drilling through material into table
surfaces.
3. A quill lock (C) is located on the left side of the
head and is used to hold quill at any position.
4. The turret handle (D) is used to lower the spindle
and quill a total depth of 6".
5. Safety collars (E) are provided to prevent head
and/or table from falling when locks are released. Be
sure collars are in place and securely locked; one
under the head and one under the tilting table. No
safety collar is required for the production table as it
is rack and pinion controlled.
6. Starting switch (F) is mounted on the front of
drill press head within easy reach of the operator.
7. A speed selection chart (G) is located on the
front of the head. This chart is to provide assistance
in determining proper drill speed.
8. The model 1150HD is provided with an AC-In-
verter (H) which is pre-programmed from the factory
and requires no changing or adjustment.
OPERATING TIPS
1. Determine drill size, inspect for sharpness, in-
sert and lock securely in chuck or Morse taper.
2. Arrange at this point to protect table surface from
drill breakthrough. A piece of scrap material under
the workpiece will prevent marring table surface and
eliminate splintering at breakthrough point. Lock table
securely to prevent movement.
3. Prevent the work from being torn from operator's
hand by always securing the workpiece, jig, fixture,
or holding device to table by clamping or blocking on
the table. DO NOT use the column as a stop. Clamp
all light workpieces, jigs, fixtures, or holding devices
to the table to prevent them from being picked up as
the quill returns.
4. Select the proper RPM for the tool being used,
the material being machined, the operations to be
performed, and other conditions as indicated. (See
Tables I, II, and III on pages 17-20 for recommenda-
tions.) If drill press is the step pulley type, raise door
and set drive belt in proper ration position. If the ma-
chine is a variable speed model, turn machine on and
turn control cam to proper speed. NEVER attempt
speed adjustment of variable speed machines un-
less machine is running. Turn machine off.
5. On tilting table models, be sure to block the part
or holding fixture from sliding off the table when it is
used tilted at an angle. In addition, be sure the table
is clamped.
6. Set depth stop for desired hole depth. Fine ad-
justment is made by turning the fine adjustment col-
lar. Use upper collar to lock stop setting position.
7. If coolant is being used, start flow.
8. Turn machine on and begin drilling operation.
As the breakthrough point is reached, always slow
feed rate down slightly to assist in elimination of burr-
ing underside of workpiece and to help prevent a sud-
den break through which can cause the drill to grab
and pull the workpiece free of its clamping device.
8. Perform all operations with a minimum exten-
sion of the quill. Adjust table or head position rather
than using excessive quill travel.
