gauge. Lock the workhead spindle with the spindle in the horizontal zero
degree position.

2. Mount the toothrest assembly on top of the workhead in a position as
shown in Photo 25, if the cutter edge to be sharpened is facing up. Or,
the toothrest may be set on the table, pointed upwards at the tooth edge,
if the latter is to be faced downward at the point of grinding. Use the
micrometer toothrest with spring-loaded rest, positioning the blade as
close to the end and edge of the tooth flute as possible The blade must
be able to spring outward when the cutter is rotated for sharpening the
next tooth
3. Rotate the workhead laterally to the desired chamfer angle and lock,
positioned on the table relative to the wheel as shown in Photo 25
4. Loosen the vertical swivel of the workhead and tilt it up (or down)
as shown, to produce the desired primary clearance, then tighten.
5 Grind the primary clearance on all teeth. Without moving the toothrest,
repeat the above process for the secondary clearance by further tilt of
the workhead. Grind the secondary clearance to where the primary land

6. To sharpen the face (ENDS) of the teeth, first use the height gauge to
put a tooth in the same horizontal plane as the center of the mill. Lock
the workhead spindle Create a toothrest set-up similar to A-2 above,
only working from the right side of the wheel if cutter edge is to face
up at the point of contact If the cutter edge is to face down at the
point of contact, the toothrest will be set on the table, pointed upward
at the left front edge of the tooth flute In the latter case, complete
step 8 below first.
7 Swivel the workhead in the horizontal plane so that the face of a tooth
will parallel the table travel, thus maintaining the radial cutting land relief
toward the center of the cutter This is usually on the order of several
degrees slope toward the center of the mill. Lock the lower swivel.
8. Loosen the vertical swivel of the workhead, tilt it to the desired primary
clearance angle, and lock. Photo 26 shows this operation, with the work­
head at a
compound angle with the swivel table to achieve the necessary
distance from the workhead to the wheel.
9. Begin grinding the primary clearance, checking tooth initially for proper
