Hydraulic groove-cutting machine KM4000

electric

Overview
The CLIMAX KM4000 key mill is a portable machine for cutting precision keyways and wide slots on industrial shafts. With a 2" (50.8 mm) sideshift and compact mounting requirements, it reduces the need for multiple cutter sizes and shortens setup time. Engineered for field and shop use, the KM4000 operates on shafts from 4 to 24" (101.6–609.6 mm) diameter and is available for sale or rental. CE and CSA certification options are provided where required.

Applications & Versatility

• On‑site and workshop keyway machining for power generation, mining, marine and heavy equipment maintenance
• Cutting mounting slots, relief pockets and engine keyways
• Field repair, overhaul and planned maintenance operations

Product Advantages

• 2" (50.8 mm) lateral travel (sideshift) enables cutting wide pockets or slots with a single end mill
• Mounts anywhere along the shaft and at any angle for in‑place machining
• Compatible with shafts 4–24" (101.6–609.6 mm) diameter
• Universal-type motor and triple gear reduction deliver high torque for efficient cutting
• Anti‑friction bearings and dovetail ways provide smooth, precise longitudinal and transverse movement
• Self‑centering, self‑aligning contoured base ensures the keyway is centered on the shaft
• Precision Acme leadscrew with roller thrust bearings and zeroing-type depth dial for accurate depth control
• Permanently sealed lubrication allows operation at any angle; motor with soft‑start maintains speed under load
• Rapid longitudinal travel option via drill motor for quicker setups

Technical Data & Notes
