Description

This pristine Hardinge HLV-H toolroom lathe received a comprehensive OmniTurn G4 CNC upgrade and full spindle rebuild just three years ago. This advanced integration transforms a traditional manual machine into a high-speed, fully automated production powerhouse, eliminating the legacy DOS bugs and hardware degradation common in older retrofits. Built on the ultra-rigid Hardinge wide-bed platform, this machine features an ultra-precise spindle rebuilt in 2023 that continues to hold tighter than a 0.0001" runout tolerance. This hybrid setup represents a modern toolroom instrument optimized for high-precision secondary operations without the massive capital overhead or massive footprint of a standard turning center.

Key Features & Benefits
The integrated Windows-based OmniTurn G4 CNC system features rapid USB and Ethernet connectivity for flawless, direct program loading from CAM software like Fusion 360. Utilizing a high-performance gang-tool plate layout, it eliminates traditional tool post indexing to provide near-zero chip-to-chip cycle times, proving highly popular with boutique aerospace, medical, and everyday carry (EDC) manufacturing shops. The system delivers synchronized CNC threading, simultaneous axis capabilities (including software plane switching for face milling operations), and retains legendary manual mechanical repeatability.

Under power ready for inspection.

Adding an OmniTurn G4 retrofit transforms a manual Hardinge HLV-H into a high-speed CNC gang-tool lathe. It essentially replaces the manual carriage with a precision CNC slide, turning a toolroom lathe into a production powerhouse.

Here is what the machine can do once the G4 is integrated:

1. Gang Tooling Efficiency
Instead of a single tool post or a slow-indexing turret, the OmniTurn uses a gang-tool plate.

Zero Chip-to-Chip Time: Since multiple tools (drills, bores, turn tools) are mounted in a row, the machine simply slides from one tool to the next. There is no turret to rotate, which makes cycle times incredibly fast for small parts.

Precision Secondary Ops: It retains the Hardinge’s legendary spindle accuracy but adds the repeatability of CNC servos ($0.0001"$).

2. Expanded Axis Capabilities
While the base retrofit is a 2-axis (X and Z) system, the G4 control is significantly more capable than older versions:

C-Axis Support: The G4 control typically comes standard with 3-axis simultaneous control (X, Z, and C). If you add a spindle encoder and drive, you gain full spindle indexing and contouring.

Live Tooling: With the C-axis enabled, you can mount powered tools (like the NSK live tool attachments) on the gang plate to perform cross-drilling, slotting, and milling on the face or side of the part.

4th Axis Option: The G4 can even be configured for a 4th simultaneous axis if your setup requires a specialized attachment like a rotary table or independent slide.

3. Advanced Programming & Threading
Complex Threading: You can perform inch, metric, tapered, and multi-start threading far more easily than using the manual gearbox.

Plane Switching: The G4 allows you to switch planes in the software, meaning you can program the machine as a mill for features on the face of the part.

Modern Connectivity: Unlike the older G3 controls that relied on floppies, the G4 uses Ethernet and USB, making it much easier to drop programs from Fusion 360 or other CAM software directly into the machine.

4. "Secondary Operation" Specialist
This setup is a "favorite" for shops that need to take a part off a larger CNC and finish a high-precision feature (like a bearing seat or a tiny thread). It’s much faster and cheaper to run an OmniTurn-Hardinge hybrid for these tasks than to tie up a $100k+ 5-axis mill-turn.

Market Context: Over $6,000 was invested directly into this platform's spindle mechanics and premium G4 controls during its recent update cycle, providing substantial asset equity compared to standard retrofits. Given the robust secondary-market demand from specialized machining shops for high-accuracy gang-tool solutions, this unit is priced aggressively to ensure rapid ROI and immediate shop-floor integration.
