Instruction Manual
Section Five
Keep in mind that when this method is employed, each time the Toothrest
Adjustment Collar is rotated, or micrometer toothrest lowered, the wheel
centerline must be relocated at the same height as that of the cutter
center. (See Chapter 1, Section Five). This will usually mean lower the
Wheelhead a given amount.
3. Use the fixture in the same manner as a fixed spindle workhead for sharp
ening the ends of the teeth. To accomplish this, set the Toothrest Adjust
ing Collar (B982CC) bracket for '0' degrees rotation and tighten the Index
and Stop Collars which will leave the spindle in a convenient position.
Depress the Rocker Arm (B982-21) to the horizontal position. Turn the
fixture spindle about 88 degrees from the longitudinal position, tilt the
fixture end downward the required clearance angle for the teeth ends, and
lock the vertical and horizontal swivels. Adjust the micrometer toothrest
until a tooth edge is the same height as the center of the mill. Loosen
the table stops and re-adjust them as necessary to limit table travel.
Grind the teeth ends (BOTH PRIMARY AND SECONDARY CLEARANCE
ANCLES) according to the instructions in Chapter 4. Cash ends by
further depression of the fixture front end, or remove the mill for hand
gashing.
C. Maintenance:
1. Do not move the spindle tube when covered with oil or dirt. Clean prior
to moving, leave no oil film. Do not attempt to remove the tube, unless
rust or dirt has worked into the center of the spindle.
2. Do not polish the bearings with abrasive materials. Keep the spindle tube
free from knicks or scratches. Store in a clean dry place.
3. Always use an air line dryer, or water trap. Use at least 50 Ibs./sq. inch
air (or inert gas) pressure; 80 Ibs./sq. inch is ideal.
