Unequalled accuracy

The Clausing is a precision machine tool built to tolerances

that are tightest in the industry.

WITHIN

Spindle taper (internal) run-out is within .0002"

at spindle nose.

"We use our Clausings for jig bore

work - in fact, any job that has to be

on the nose is machined on a Clausing."

EXCEPTIONAL

VERSATILITY

The Clausing drills, mills, bores, reams - at all angles

- with one work setup. The spindle head swivels in a

vertical plane, turret head rotates in a horizontal plane.

Countershaft drive with six. speeds

-180

to 325D rpm

- efficiently handles a wide range of tools and materials.

There are two spindle feed controls - a handwheel for

fine feeds, a lever for fast feeds.

Positive stop with graduated dial provides accurate

depth control. Lever bf*e stops

spindle

quickly:

And, lor - 'round-the-clock operation Clausing has-

hardened chrome-nickel steel spindle, hard-chrome-plated

quill with full-length bearing, wide dovetail ways with

full-length gibs, solid cast over-arm, fifteen ball bearings.

... for production

SUPER SENSITIVITY

"C lausing has the sensitivity you can't get in larger

machines - and it is the easiest to set up, get around

and operate of any mill."

Ground thread feed screws haue gauge-tolerance

lead accuracy -

±

.0005"

within any two threads in

three inches.

Precision feed screws - with eight ball bearings - plus

hand fitted ways provide the smooth action for

feel-control

of table, saddle and knee.

And, each quill is custom fitted - bearing surface is

honed.

Clausing has the balance, sensitivity- whatever you

call it when you .feel the cutter working, and can transmit

all your skill to the job.
