STEALTH 1165
The STEALTH 1165 Vertical Machining Center brings heavy-duty, gear-driven cutting power to the STEALTH lineup. A 25 HP, 2-step gear-driven spindle with a Big Plus CAT50 taper delivers the torque needed for aggressive material removal, while rigid box guideways and precision hand-scraped metal-to-metal contact surfaces provide long-term accuracy, vibration dampening, and extended machine life.
Every STEALTH 1165 arrives production-ready with a FANUC OiMF PLUS control and WELE iSmartTune package, a 40-pocket automatic tool changer, 300 PSI coolant through spindle, dual chip augers with coolant washdown, and BLUM tool setting and probing — all standard.

Gear-Driven Torque for Demanding Cuts
At the heart of the STEALTH 1165 is a 2-step gear-driven spindle built for torque, not just speed. The low gear range delivers up to 466 N·m (344 ft-lb) of torque for heavy roughing, face milling, and large-diameter tooling. The high gear range carries full spindle power through the mid-speed range for efficient finishing.
- 25 HP spindle motor with 2-step gear transmission
- 6,000 RPM maximum spindle speed
- Big Plus CAT50 dual-contact taper for maximum tool rigidity and accuracy
- Supports tools up to 15.4 lb (7 kg) and 11.8 in (300 mm) long
Crafted for Stability. Engineered for Results.
Every metal contact surface on the STEALTH 1165 is precision hand-scraped by WELE craftsmen. Hand scraping creates thousands of tiny bearing points that hold oil, seat components flat, and absorb vibration. The result is long-term geometric accuracy, smoother surface finishes, and extended machine life.
Box guideways add mass and damping where heavy cuts need it most. Together with the hand-scraped joints, they give the STEALTH 1165 the stability to take aggressive cuts without chatter.
Accuracy You Can Count On
The STEALTH 1165 holds tight tolerances part after part, measured to JIS standards.
- Positioning accuracy: ±0.0002 in (±0.005 mm)
- Repeatability: ±0.0001 in (±0.003 mm)
- AI Contour Control II, Smooth Tolerance Control, and Nano Interpolation for accurate, smooth tool-paths
A Generous Work Envelope
With 43.3 in of X travel and a 51.2 x 25.6 in table, the STEALTH 1165 handles large plates, multiple fixtures, and long parts in a single setup.
- Travels (X / Y / Z): 43.3 x 25.6 x 23.6 in (1,100 x 650 x 600 mm)
- Table size: 51.2 x 25.6 in (1,300 x 650 mm)
- T-slots: 18 mm wide on 125 mm (4.9 in) centers
- Spindle nose to table: 4.9 – 28.5 in (125 – 725 mm)
- Rapid traverse: 1,181 ipm (30 m/min) X/Y, 945 ipm (24 m/min) Z
Tooling
The chain-type, 40-pocket automatic tool changer keeps a full job's worth of tools in the machine. Random, bi-directional tool selection takes the shortest path to the next tool, cutting tool-change time.
- Max. tool diameter: 5.0 in (127 mm) with adjacent pockets full; 9.0 in (229 mm) with adjacent pockets empty
- Max. tool length from gage line: 11.8 in (300 mm)
- Max. tool weight: 15.4 lb (7 kg)
User-Friendly Operation
The FANUC OiMF PLUS controller on the STEALTH 1165 delivers powerful, user-friendly CNC performance on FANUC's latest platform. A 15-inch touchscreen and WELE's built-in Operation Supporter package provide a full suite of machine monitoring and operation support functions. A full-keyboard CNC pendant with hard push buttons combines touchscreen convenience with the tactile reliability operators expect.

Additional Features
Coolant & Chip Management Built In
Heavy cutting requires efficient chip removal. The STEALTH 1165 clears out chips with dual augers, including an X-axis auger, plus an integrated coolant washdown system. High-pressure coolant through the spindle flushes chips from deep holes and pockets and extends tool life.
- Coolant through spindle: 300 PSI (20 bar)
- Flood coolant: 20 GPM
- Coolant tank capacity: 147.2 gal
Probing & Tool Setting Included
The STEALTH 1165 ships with a BLUM ZX-Speed laser tool measurement system and TC50 workpiece probe as standard. Measure tools and locate parts automatically, then use the built-in probe and tool-setter screens to drop results straight into your CNC programs. Setups get faster and first-part scrap goes down.
Ready for Automation
The STEALTH 1165 is ready to grow with your shop. The FANUC control supports 4-axis operation, with an option for 5 axes. Pair the machine with productivity enhancements such as rotary tables, robotic part loading, pallet changers, automated tool storage, and high-pressure coolant units. Ask your JTEKT representative about a complete turnkey cell or a custom automated solution to meet your manufacturing objectives.
