3.9 KM3000 SMALL SHAFT MOUNTING
Using the rear clamping holes, mount the key
mill onto shafts 0.75–1.5" (19–38 mm) diameter
by placing a matched pair of spacers, or shims,
extending the full length of the base at the edge
of the throat.
If the shaft diameter is between 1.5–2.9" (38.1–
73.7 mm), use the front mounting holes in the
base.
Check that the shaft is in the open part of the throat only. If it extends
into the rear or the base, it will not align with the key mill.
Contact CLIMAX for a shim kit (P/N 11669).
3.10 KM4000 SMALL SHAFT MOUNTING
When mounting the KM4000 to shafts less than 7" (178 mm) diameter, an optional
shim kit is recommended. Shims are mounted to the base throat with flat-headed
cap screws. The shim kit (P/N 11851) enables the key mill to be mounted to shafts
with diameters as small as 4" (100 mm).
If the shaft is disassembled, the key mill may be bench mounted and the shaft
clamped to the machine.
3.11 KM3000/KM4000 EXTRA LONG SHAFT MOUNTING
If the shaft is long enough, V-blocks can be used to secure the shaft. A chain
wrench or C-clamp may be used to hold the shaft and V-blocks together.
Extra long shaft mounting setup and operation of the key mill is the
same as for standard shafts.
Place a level on the keymill top slide to maintain keyway alignment along a long
shaft.
