USED HAAS GR-712 – 2017
The HAAS GR-712 – 2017 is a large-format CNC gantry router designed for machining exceptionally large workpieces, sheets, panels, composites, plastics, aluminum, and other non-ferrous materials. The GR-712 combines a rigid steel gantry structure with a large fixed worktable, long X-axis travel, wide Y-axis travel, and a 40-taper spindle. Its large machining envelope makes it particularly useful for manufacturers that need CNC cutting capability far beyond the working area of conventional vertical machining centers.
The 2017 GR-712 provides approximately 145 inches of X-axis travel, 85 inches of Y-axis travel, and 11 inches of Z-axis travel. The machine has a 144 × 72-inch table with a 1-inch-thick aluminum surface and a maximum evenly distributed table load of approximately 6,000 lbs. The distance between columns is approximately 86 inches, providing substantial working width for large components and sheet material.
The documented 2017 machine is equipped with a 15 HP, 8,100 RPM spindle, a 40-taper spindle interface, and a 20-tool carousel automatic tool changer. The standard GR-712 specification lists a 10-tool changer, while the documented 2017 machine has the larger 20-tool configuration. It also includes a Haas NGC control, Haas P-Cool coolant system, Renishaw spindle touch probe, and tool touch probe.
The HAAS GR-712 – 2017 is especially suited to aerospace components, transportation parts, composite panels, large aluminum components, industrial fixtures, molds, signage, architectural components, and other large-format parts. Its exceptionally long X-axis and wide Y-axis allow manufacturers to machine large sheets and structures in a single setup, reducing the need for repositioning and multiple machine setups.

WHY CHOOSE HAAS GR-712 2017
The HAAS GR-712 – 2017 is an excellent choice when machining size is the primary requirement. Its 145-inch X travel, 85-inch Y travel, and 11-inch Z travel provide an enormous working envelope compared with conventional vertical machining centers.
The 144 × 72-inch table and 6,000-lb evenly distributed load capacity allow large sheets, fixtures, panels, and assemblies to be positioned directly on the machine. The 40-taper, 15 HP, 8,100 RPM spindle provides sufficient speed and power for a broad range of aluminum, composite, plastic, and non-ferrous machining applications.
The documented 2017 machine is particularly attractive because it includes a 20-tool automatic tool changer, Haas NGC control, Haas P-Cool, Renishaw spindle probe, and Renishaw tool probe. These features can significantly improve setup consistency and production efficiency.
WHY BUY USED HAAS GR-712 2017
Buying a used HAAS GR-712 2017 can provide a significant opportunity for manufacturers that require large-format CNC machining without purchasing a new large-platform gantry router.
Common valuable features and options to look for include:
- Haas NGC control
- 15 HP spindle
- 8,100 RPM spindle
- 40-taper spindle
- 20-tool automatic tool changer
- 144 × 72-inch aluminum table
- Renishaw spindle probe
- Renishaw tool probe
- Haas P-Cool
- 95-gallon coolant system
- High-pressure coolant
- Through-spindle coolant
- 4th-axis preparation
- Additional rotary equipment
- Tooling package
- Vacuum or specialized workholding
Before purchasing a used GR-712, buyers should inspect gantry alignment, X/Y/Z-axis accuracy, spindle condition, spindle bearings, ballscrews, linear guides, tool changer operation, probing system, table condition, coolant system, control electronics, and traveling guard system.
Because the machine has an exceptionally large travel envelope, buyers should also verify machine geometry across the complete X/Y travel range, rather than checking accuracy only near the center of the table.
The documented 2017 machine currently listed on the used market has approximately 4,238 spindle-on hours recorded as of September 1, 2026, providing an example of why actual machine and spindle hours should be verified before purchase.
HOW MUCH DOES A USED HAAS GR-712 2017 COST?
The HAAS GR-712 – 2017 is a specialized large-format CNC machine, so pricing depends heavily on machine condition, spindle hours, table condition, control generation, tooling, probing, coolant equipment, and other accessories.
A documented 2017 GR-712 with 145 × 85 × 11-inch travels, 15 HP spindle, 8,100 RPM, 20-tool ATC, Haas NGC control, P-Cool, and Renishaw spindle and tool probes is currently listed at approximately $109,500 USD.
A reasonable estimated market range for a used HAAS GR-712 2017 is approximately $90,000–$125,000 USD, with particularly clean, low-hour, and well-equipped machines potentially commanding more.
| Machine Condition / Configuration | Estimated Used Price |
|---|---|
| Higher Hours / Basic Configuration | $90,000–$100,000 |
| Good Condition / Standard Configuration | $100,000–$110,000 |
| Low Hours / Well Equipped | $110,000–$125,000 |
| Exceptional Condition / Extensive Options | $125,000+ Possible |
The final selling price should be based on machine hours, spindle hours, spindle condition, gantry accuracy, axis backlash, table condition, Haas NGC control, ATC operation, Renishaw probing, coolant system, tooling, fourth-axis equipment, maintenance history, and the ability to demonstrate the machine under power.
