Innovative Tool Sales

The Autofacer® is the most robust and versatile back spotface, counterbore, chamfer, spherical cut, or profile cutting solution ever produced.

Autofacer’s are available in applications starting at 1/4” pilot hole size and up.

•  Pilot sizes 5/8” and larger are standard with through the tool coolant and rotary pilot.

•  Available in several different confi-gurations, engineered for use on modern CNC’s, transfer lines or manual equipment.

•  Designed to run at high speeds and relatively low feed rates.

•  Autofacers are actuated by internal friction clutches- allows tools to perform heavy interrupted cuts smoothly without excessive chatter.

•  Ideal application tool for eliminating costly 2nd operations and saving time through process improvement.

•  Chip to chip time lowered by as much as 80% over conventional methods.

Typical Industries using Autofacers

Air or Coolant Pressure Activated

     •No spindle reversal required

     •Minimum 200psi and 10 micron filter

     •Short compact design is ideal for
       transfer lines and CNC machines.

   •Ease of Operation-simple to set up and program.
   •Very high reliability- tool is opened &
closed by spindle reversal, very positive.
Well suited for high production applications.
   •Cutter blade is positively held open- internal friction clutch allows for heavy interrupted cuts.
   •Flexible high precision PC6 connection
allows for excellent repeatability and also great flexibility between different tools.

6000 Series Extended Range Autofacer

    • Allows for larger spotface to pilot diameter ratio’s.
    •Available Coolant Pressure or Torque Bar Activated.
    •“Unlimited” spotface diameter range.
    • Fast machining cycle, activation is
instantaneous with either spindle reversal or turning on coolant-through-spindle.
    • Very high reliability, well suited for
demanding high production applications.

     •Ultra high precision applications to achieve tolerances of +/-.0001”.
     •Excellent for solving long length to diameter ratio applications.

Inertia Activated

   •Ease of Operation- tool is activated by spindle reversal.
   •Faster machining cycle-no need to
bump or contact work piece.
   • Very high reliability-simple and
advanced design ideal for modern
CNC machines.
   •Cutter blade is positively held open internal friction clutch allows tool to
perform heavy interrupted cuts.
   • Requires machine acceleration &
deceleration to properly open & close
cutter blade.

• Simple and functional design, well
suited for short to medium production runs.
• Sizes from 1/4” to 1-3/16” pilot
diameter are equipped with calibrated
brass shear pins to provide protection
from axial overload.
• Versatility: adaptable to CNC and
manual machines.

Heavy interrupted cuts are no problem due to friction clutch positively holding open cutter blade during cut.

Cycle time savings are enormous vs the old 2-piece method. 48 minutes per hole to under 5minutes per hole.

     An Extended Range Autofacer, using an indexable insert and master holder, machining a spotface in a differential case.

     Note that the extended range autofacer flips its cutting blade out like a jack-knife blade.

     This style of Autofacer is also supplied with a brazed carbide blade. Blades can be shaped to cut spherical radii, chamfers, steps, and various other profiles, either separately or in combination.

Special Configurations

• Front and Back Countersinking
• Cutting Spherical Radius
in Automotive Differential Cases
 • Combination Backfacing and Grooving
