2.1.2 KM4000 features and components
The KM4000 key mill machine is designed to cut extra wide keyways, stress relief
pockets, motor mount slots, and more. Built for rugged duty, the machine features
permanently lubricated reduction gears so the machine can be operated at any
angle. Anti-friction bearings are used throughout.
The dovetail ways are machined to offer smooth movement in both the longitudi-
nal and side travel directions.
An electronic speed control offers precision control of spindle speeds.
The 2" (51 mm) side travel allows cutting wide pockets or slots with a single end
mill.
The KM4000 mounts on shafts up to 24" (609 mm) in diameter (with optional
extra chain) and may be used anywhere along the shaft. With the optional shim kit
the machine can be used on shafts as small as 4" (100 mm) in diameter.
• Compact, rugged, portable milling machine for on-site keyway and
other milling jobs
• Mounts on shafts from 4–24" (101–610 mm) in diameter
• Cuts new keyways up to 3.25" (83 mm) wide and 7.88" (200 mm) long
in one setup (cut dimensions include the width of the end mill)
• Contoured base is self-aligning with the shaft
• Triple gear reduction with permanently sealed lubrication
• Zeroing type adjusting dial for controlling cutter depth
