4.6 KM3000/KM4000 SPECIAL APPLICATIONS
The KM3000/KM4000 is well suited for machining unusual keyways and other
exceptional on-site milling jobs. The KM3000/KM4000 works well on almost any
operation calling for the milling of slots, flats, elongated holes, or other like fea-
tures.
4.6.1 KM3000/KM4000 long/extended keyways
Do the following to cut in-line keyways:
1. Secure the shaft so it will not rotate. V-blocks may be used to hold long
shafts. Secure the shaft to the V-blocks with C clamps.
2. Mount the key mill to the shaft as described in Section 3.4 on page 23.
3. Carefully level the key mill on top of the shaft. A level can be placed on the
machined upper surface of the base to check the key mill.
4. Cut the keyway as described in Section 4.4 on page 38.
5. Reposition the machine along the shaft.
6. Again, carefully level the key mill on top of the shaft.
If the machine is accurately leveled each time, the keyways will always
be in line.
Single keyways can be extended, or two or more keyways precisely aligned along
the length of a shaft.
