Instruction Manual Section Five
(c) The Cam is now free to be removed with one's fingers. Lift it up,
as it is keyed to the Spindle.
(d) Install the correct Lift Cam and push the Spindle back into the
Housing position When the Spindle Assembly is being installed,
guide the Spindle through the rear end of the Housing by lifting
slightly the rear end of the Spindle Assembly. This procedure will
aid in clearing the relief edge at the back of the Housing.
(e) Install the Collet Adapter Assembly in reverse order of step E.
(f) Lock the Spindle Housing temporarily and proceed to mount the tap
G Inserting the Tap into the Fixture:
1. Select the proper size Collet Bushing (B947B), dependent on the tap size,
and insert it into the B641C
9
/
16
inch Collet. For taps over ⅝ inch size a
special B641C800 Collet and B647B Collet Bushings are used.
2. Insert the tap shank into the Collet Bushing Assembly up to the threads
of the tap, if possible.
3. Lock the tap in the Collet by holding the Spindle Collet Adapter (No. 12)
with the handle of a B628 V* inch Socket Wrench (standard equipment
for K. 0 Lee Grinders) or similar round bar and tighten the Collet Draw
Tube Handwheel at the back end of the Spindle.
H. Set the Flute Clearance by Synchronizing the Lift Cam with the Tap Radial
Clearance Lands.
1. Turn the Collet Drawtube Handwheel in the opposite direction of the
tap's cutting edge until the Spindle and its Index Disc hit the positive stop
of the Lift Cam.
2. Unlock the Spindle Housing by releasing the Hex Socket Cap Screw
(No. 25).
3. Turn the entire Spindle Assembly in the opposite direction from tap's
leading or cutting edge so that the heel of the radial clearance land on
the grinding wheel side of the table is slightly above the fixture center
horizontal plane for the right-hand taps and slightly below this horizontal
plane for left-hand taps (THE SPINDLE IS ROTATED IN THE OPPO­
SITE DIRECTION TO THAT USED FOR SHARPENING).
4. Relock the Spindle Housing.
I. Sharpening the Tap While Producing the Radial Relief on the Teeth:
1. Set the Wheelhead spindle at 90 degrees relative to the table.
2. Position the fixture and the table with the table handwheel so that the
desired tap chamfer will be amply covered by the wheel side.
3. Feed the tap toward the wheel, using the grinder Crossfeed, to a position
just short of the wheel as shown in Photo 53.
4. Rotate the tap in its cutting direction with the handwheel and continue
the Crossfeed approach until grinding action begins. After initial contact
with all flutes, move the table aside to check for correct relief generation.
5. Continue until the chamfer is produced and the tap cutting edges appear
sharp. Care must be used to avoid any grinding action which will cause
discoloration of the tap.
