Milling Machine Applications
- Heavy-duty face milling, aggressive slotting, and large-scale profiling on bulky workpieces up to 925 lbs.
- High-efficiency production runs utilizing the integrated X, Y, and Z-axis powerfeeds for consistent, hands-free chip loads.
- Rapid-turnaround job shops and custom tooling operations leveraging the pneumatic air drawbar for instant tool swaps.
- Complex multi-angle machining utilizing the fully articulating head (45° left tilt, 90° right tilt).

Performance, Safety & Integration Features
- Integrated Air Power Drawbar: Allows operators to swap NST-40 tooling in seconds with the push of a button, drastically reducing cycle times between operations.
- 3-Axis Powerfeed System: Fully automates the X, Y, and Z axes, ensuring perfectly consistent surface finishes and massively reducing operator fatigue during long shifts.
- Automatic Lubrication System: Provides ongoing, metered lubrication to the ways and leadscrews every 180 minutes, maximizing machine lifespan and preventing wear.
- Certified Meehanite® Castings: Supply unparalleled structural rigidity and vibration dampening during intense, large-scale cutting and boring operations.
- Heavy-Duty Spindle Brake: Rapidly and safely stops the massive NST-40 spindle to increase shop safety and streamline manual tool inspections.
- Three-Stage Power Downfeed: Includes an automatic stop mechanism (.0015", .003", .008" IPR) for highly accurate, repeatable Z-axis plunging.
- Precision Hardened & Ground Ways: Paired with adjustable gibs throughout to maintain incredibly tight geometric tolerances and smooth carriage glides over the 54" table.
