Instruction Manual Section Five
must be swiveled the angle equivalent to that between the cutting edges and
the axis of the cutter. See Chapter 3, I and II. If the angular cutter is to
be shank mounted in a workhead, the set-up is identical to that of a shell end
mill, except that the table or workhead must be swiveled in the horizontal
plane to the angle of the cutter. See Chapter 4, I and II The toothrest is
mounted on either the Wheelhead or the table.
B. With some shank-mounted cutters, interference between the shank and the
flared cup wheel used in the above set-ups will prevent sharpening the full
length of the teeth. When this interference occurs, substitute the following
set-up, which also produces a constant clearance angle.
II. SET-UP FOR SHARPENING THE PERIPHERY WITH A SAUCER WHEEL
A. Mount a saucer wheel on a spindle collet or arbor opposite the belt-driven end
of the spindle, and mount the appropriate wheel guard. Start the Wheelhead
motor and dress off the periphery of the wheel to a width of ⅛ inch with a
diamond dresser. Stop the wheel.
B. After placing the axis of the spindle parallel with the table travel, tighten
the Wheelhead swivels. Mount the universal toothrest assembly on the table
or workhead from above or below the cutter, depending on whether the cutter
edge faces up or down at the point of contact with the wheel With the use
of the height gauge, place the blade end of the toothrest on centerline with
the cutter center just back of the cutter O.D., on one tooth. Also place the
centerline of the cutter on the same horizontal plane as the centerline of the
wheel. Set the index dial of the Wheelhead handwheel to 0
C Lower or raise the Wheelhead the required amount according to Table I, page
104, in order to generate the desired clearance angle.
D With the cutter teeth set parallel to the table travel (as in I-A above) and
the cutter held against the toothrest, traverse a tooth by the periphery of
the wheel to the left or right of the wheel to a point where the wheel edge
just avoids the shank of the cutter At this point, set a table stop to limit
further travel in this direction
E. Start the Wheelhead motor and proceed to grind the primary and secondary
clearance on all teeth as in the chapters mentioned above
F. Sharpening the face and chamfer is done as described for end mills in Chapter
4. IV, using a cup wheel ( see Photo 31).
CHAPTER 8
Face Mills
Face mills up to 14 inches in diameter may be sharpened on machine model series
BA900 or B2000 by use of a raising block under the workhead, while standard work­
head height allows for sharpening cutters up to 12 inches in diameter. The B6000
series machine models allow face mills up to 16 inches in diameter to be ground
without the addition of raising blocks. Face mills of no larger diameter than 10
inches may be mounted and sharpened on the B300 series machines.
The following is the operations procedure for sharpening a 12-inch diameter face
mill with inserted carbide blades with cutter edges having an end relief of 2 de-
