Introduction And General Information; Technical Data - Quackenbush 120SC - 225 Operation & Service Manual

Introduction and General Information

The Q-Matic 120SC-225 are air operated, hydraulically
controlled tool that automatically clamps to the material,
drills and countersinks close tolerance holes in one opera-
tion. The Q-Matic will produce high quality holes in alumi-
num, steel, titanium and petroleum hybrid materials prima-
rily found in the aircraft/aerospace industries. The Q-Matic
self-colleting drill motor has been designed using state-of-
the-art technology that provides maximum power,minimum
weight and the highest degree of accuracy for demanding
hole preparation requirements.

Technical Data

Feed Stroke: Feed stroke of the Q-Matic 120SC-225 is 2.25
inches to drill and countersink in 2 inch stacked material. The
feed stroke is unaffected by the collet stroke.
Collet Stroke: The Q-Matic 120SC-225 will clamp through-
out its .875 inch stroke. Collet stroke is unaffected by feed
stroke.
Spindle Adjustment: The spindle adjustment of .375 inch
allows for drill length variations. See Spindle Adjustment
information on page 25.
Countersink Depth Control: A micrometer adjustment
provides for countersink stop repeatability within .001 inch.
Cutter Sizes: The Q-Matic 120SC-225 will accommodate
.500 diameter drills without countersink and.781 counter-
sink diameter.
Feed Rate: An adjustable drill feed rate mechanism enables
the Q-Matic 120SC-225 to drill from 5 seconds per inch to 1
minute per inch. See Feed Rate Adjustment information on
page 25.
Cutter to Collet Spacing: The cutter to collet distance is
adjustable between 1.00 inch minimum to 3.50 inch maxi-
mum.
Coolant: The Q-Matic 120SC-225 has a drill point coolant
port in the pressure foot. A coolant mist lubricator is available
(See Accessories Page 33-34)
Air Motor: The air motor for the 120SC-225 is rated at 1.2
horsepower nominal when supplied with air at 90 p.s.i.

Air Consumption: Air consumption of the Q-Matic 120SC-
225 is 45 c.f.m. at 90 p.s.i. dynamic.
Weight: 15SC-225 weight with the aluminum pressure foot
is 13 pounds.
Spindle Speeds: Eleven geared spindle speeds are avail-
able with the 120SC-225: 270, 470, 700, 900, 1,150, 2,200,
3,500, 5,500, 7,000, 14,000, 23,5000 RPM. See pages 30
thru 31 for gear set assembly configurations. Any gear set
can be used with the 120SC-225 tool. See pages 31 thru 32
for gear set assembly configurations.
Trigger Lock: A trigger lock is provided which allows the tool
to be locked in the "Operate" position. With the lock acti-
vated, the tool will run through the clamp, feed and retract
cycles, but it will not unclamp or stop the motor until the
trigger lock is manually released.
Tool Start-Up
The Q-Matic 120SC-225 drill is shipped from the factory
equipped to the customer's specifications: spindle RPM,
spindle to accommodate cutter type desired, pressure foot
type, collet guide to accommodate collet desired and op-
tional booster pump (if required).
After unpacking, examine the customer-specified equip-
ment on the Q-Matic tool to verify type and speed of
components. Attach air line to 3/8-18 NPT inlet bushing. If
quick disconnect fittings are used, 3/8 in. ID are minimum.
The Q-Matic 120SC-225 drill requires a supply of clean 90-
100 PSI air. Air consumption is 45 CFM at 90 PSI. The use
of the in-line lubricator will provide the proper lubrication for
the air motor and will significantly increase the tool life
expectancy.
Because O-rings are extensively used to seal systems
within the tool, the elimination of foreign particles and other
contaminants will reduce the possibility of damage to these
parts. Always inspect O-rings for damage or wear and
replace as required. The use of silicone O-ring lubricant is
strongly recommended during reassembly. The addition of
oil in the air line will also increase motor and valve life as well
as the life of the O-rings. Avoid the use of synthetic lubricants
to prevent damage to O-rings and seals.
