Lathe operators now have a quick
-and-easy way to re-center the cutting tool. Carter
Diamond Tool Corp.’s Shaft-Center
Locating Gauge is ideal for high-volume motor manufacturers.
Designed for easy use in
conventional armature lathes, the gauge quickly identifies
the shaft center relationship to
the cutting tool tip. Precision Carter centering gauges
are available with either easy-read
dial or Micrometer readout devices.

Directions
for use:
This gauge is designed to be placed in a con-
ventional production armature
lathe where the
commutator tool is normally located for the
purpose
of
determining the shaft center relationship to
the
tool tip.
1. Remove commutator turning tool from
the
tool holder
2. Check gauge assembly on a surface
plate to
be sure micrometer reads .000" when fully
extended to bottom plane
of gauge. |

3. Place
shank of gauge assembly in tool holder with micrometer
head positioned above
armature
shaft and tighten set
screws in tool holder. Micrometer should be backed off
so tip of gauge does
not touch armature shaft during setup.
4. Using ratchet stop thimble of micrometer,
turn barrel clockwise until ratchet slips.
5. Micrometer reading should be equal
to: 1/2 the shaft diameter+.152" (PCD tipped tool
with tip down) EXAMPLE: with
3/8" shaft = (.375" x 1/2)+.152" =.3395" (Note:
calculations
are based on standard tool height tolerance of. 152" to
.156" top
of tool to cutting tip.)
6. When measurement is complete, remove
complete gauge assembly from tool holder and
return to
storage box.
Do not loosen screw holding micrometer head in gauge
assembly! |
