Introduction
PROCUNIERs Push-Button Lead Screw Tapping Heads
are precision made in Sizes No. 1 (Series 21000) and No. 3
(Series 23000) for extended machining life when used
within rated capacity limits. Successful operation can
only be assured if the Drill Press Spindle is in running true
condition.
Standard and Optional Equipment: Style AL Lead Screw
Tapping Heads include the following standard equipment:
three (3) piece quill clamping cover; 3' air line with fittings;
8 grounded power line with plug; a foot control switch with
8 grounded power line and plug; set of four (4) standard
tap collets; and the necessary wrenches. Optional equip-
ment such as an Air Regulator/Filter/Oiler Assembly com-
plete with column mounting bracket; collet adapter for
conversion from internal tapping to external threading for
Acorn or round button dies; and additional PROCUNIER
Tru-Grip Tap Collets to fit all standard inch or metric taps
are available See Catalog Pages 26 and 27, No. 1 (Series
51800) and No. 3 (Series 53800).
Left-Hand Operation: When using left-hand taps, reverse
the rotation of the drill press (left to right rotation); modify
the cover assembly of the tapper (pin shank, drive shell and
internal ring gear) and use left-hand Lead Screw assemblies
only. If tapper is not modified for left-hand use and run in
the wrong direction, the tapping head will become dam-
aged. When not in use, tapping heads should remain in
operating position because of their gravity oiling system.
Tappers cannot be used in inverted position.
Set-Up
Mounting: This Lead Screw Tapper is equipped with a quill
clamping type cover consisting of: a) the basic cover
casting (mounted to the unit); b) flange to be drilled as
required to attach the drill press stop rod; and c) collar
(reducing the cover bore to the diameter of the drill press
quill). When the quill diameter and cover bore are equal, no
collar is necessary.
Attaching the head to a drill press should be done in the
following steps:
1. If spindle is not Morse taper type, mount the separate
drive adapter (DA) furnished, to drill press chuck taper.
2. Slide the tapping head over spindle onto quill (if M.T.
type, engage taper completely if C.T. type, line up slot
with driving dogs on shank (S) and engage), then tight-
en flange screw (FS) to secure complete head to drill
press with nameplate facing front.
3. Lock quill and depth stop rod of the drill press to pre-
vent tapping head movement.
After the tapper is mounted, connect the air hose to the
solenoid valve inlet at the rear (No. 1 heads have a 1/8"
pipe fitting; No. 3, a 1/4" pipe fitting). Connect the opposite
end to the Out side of the Regulator/Filter/Oiler
Assembly the In side is then connected to the plant air
supply.
Although it is MANDATORY that a Regulator/Filter/
Oiler Assembly be used for foolproof operation, more
than one tapper can be operated off the same air control
as long as air pressure requirements are equivalent. Proper
air pressures for most operations are: 15-70 psi (No. 1); 20-
90 psi (No. 3). Minimum air pressure (enough to drive a
sharp tap) is more economical and assures tap protection,
since the friction clutch will slip rather than causing tap
breakdown excessive pressure will cause a malfunction
of the solenoid valve and damage the tapper.
The lubricator unit should be filled according to the
instructions on the unit, using a light grade machine oil like
SAE 10W. Adjust the regulator on the top of the unit so that
one drop of oil forms in the sight bubble every 2 minutes.
Over-lubrication can clog the air cylinders.
Electrical: Plug the foot control (86) and line cord (93) to
the rear of the tapping head and to the power source,
grounding it for protection. All circuits are factory tested
and require no additional adjustment. Make sure that the
tapper voltage (indicated on the nameplate) is the same
as the power source, normally 120 volt, single phase, 60
cycle.
When not in operation, the 3-way toggle switch on the
front nameplate should be in the OFF position, the power
disconnected and the air shut off. Always disconnect the
power plug when adjusting or replacing electrical
components.
Speed: Select the proper speed for the tap (See Catalog
Page 29) and adjust the drill press pulleys accordingly.
Speed ratios in the tapper are: 1:1 drive, 1:2 reverse (input
to output). Speeds in excess of 2000 RPM (No. 1-AL) and
1200 RPM (No. 3-AL) are not recommended. Maximum
cycles/hour are: No. 1-AL 3600; No. 3-AL 1800. Ex-
ceeding these limits will cause excessive component wear
and possibly damage the tapper.
Depth Adjustment: Tap feed is accomplished in the head
itself, with stroke adjustable up to 3/4" (No. 1-AL); up to 2-
1/4" (No. 3-AL). To change the stroke, loosen the depth
stop lock nut (47) and adjust the depth nut (46) up or down;
then relock the nut. Wrenches are provided for locking the
hex jam nut (47) against the depth stop nut to maintain the
correct depth. Once set, the lead screw will repeat depth
to within 1/3 turn of the lead screw.
Tapping: The one-piece Lead Screw and Tru-Grip tap
chuck accommodate the collet which holds the tap. Insert
the tap into the collet completely, making certain that the
square of the tap is totally engaged in the collet. If the tap
is not completely engaged, it will cut out the square in the
collet. Insert the entire assembly into the chuck and lock in
place using the wrenches provided.

Once the drill press is started, the Lead Screw will feed
in reverse until it reaches the neutral position and is ready
for operation. Be sure the tap is of the correct G.H. num-
ber to produce the desired class of fit. Accurate alignment
of tap and hole is essential for good threads. The proper oil
based lubricant flowed on for the material being tapped
will reduce load, assure better quality threads and length-
en tap life. (See Catalog Page 29 for recommended drill
press speeds and lubricants.)
Lubrication: Tapping Heads should be lubricated with 6
drops of light grade machine oil (SAE 10W) every 4 hours
of operation in oiler at top of housing. Use liberal amounts
of lubricant in the split in the Lead Screw nut at bottom of
housing and yoke bushing (44). The Tapping Head should
be lubricated before using, but do not flood, since glazing
of the clutch will result and reduce drive capacity. Under
heavy use, remove clutch and clean periodically. (See
Disassembly.)
Lead Screw Assembly: To remove the Lead Screw
assembly from the tapper, turn lead screw down by hand
approximately 1/2" to relieve upward pressure on the lead
screw drive collar (61). Slip the drive collar snap ring (62)
off without bending or distorting it, push the drive collar pin
(63) out of the drive collar (61), then remove both socket
head cap screws (66) in the bottom of the cap.
PROCUNIERs Lead Screw assembly is wear-adjustable
simply by opening or closing the three (3) set screws locat-
ed on the black cap. Adjust each until the Lead Screw
turns freely without excessive float or runout, making sure
the Lead Screw bronze nut is securely in the Lead Screw
cap. Always adjust the Lead Screw assembly when it is
disassembled from the unit.
Reverse the above procedure for reassembly.
Operating Procedures
General
PROCUNIER Lead Screw Tapping Heads feature three
electrical modes: Automatic, Manual Jog Cycle and
Manual Single Cycle. Each is explained below.
Color-coded components simplify maintenance and re-
pair. To replace any component, first disconnect the power
cord, then replace the component and connect like-col-
ored wires together; e.g., yellow to yellow, blue to blue, etc.
Should the tap stick , bind, hit an obstruction or the bot-
tom of the hole, the Safety Return button immediately
interrupts the cycle and returns the tap to the start of its
stroke.
Indexing tables or other automatic features can usually
be wired to the tapping head through an external switch
located on the tapper body
