Comtorgage

BORE GAGE

VARIABLE - 3 POINT CONTACT

( provides average measurements )

Ideal for checking tri-lobed bores, interrupted I.D.'s, or thin walled parts.

Three-Segment design ( available for .120" and above diameters ) produces movement in three planes, and maintains true 120° contact through entire measuring range.

 Two-Segment design ( available for .870" and above diameters ) produces movement in vertical plane only, and can be used in applications where contacts are not equally spaced.

• Permits checking for taper, barrel shape,    hourglass or bell mouth
• Dedicated to one size for production
   purposes, no errors in set-up
• Comparative system, set to master
• Self-centralizing and self-aligning
• Built-in back taper assures contact at
   front tips
• Capable of measuring to extreme
   bottom of bore
• Contact is under constant spring load
• Measuring is independent of differing
   operator skills

 • English or Metric
• Ranges from + .003" / +/- .075MM to
   +/- .040" / +/- 1.00MM
• Contacts hardened to 60-62
   Rockwell C
• Can be Chrome Plated or fit with
   Carbide inserts to extend wear factor
• Self-compensating for wear
• Usable as a totally mechanical gage or
   in an electronic set-up
• Suitable for use at the machine or in an
   inspection environment
• Easily disassembled for quick change
   over and cleaning
