Overview

The Quintax G Series is a heavy-duty gantry-style 5-axis CNC router engineered for machining large aerospace tooling masters, composite layup tools, and full-scale structural composite assemblies that exceed the work envelope of conventional bridge-style routers. Built by Quintax Inc. in Hudson, Ohio, the G Series is designed for Tier 1 and Tier 2 aerospace manufacturers, naval defense fabricators, and wind energy producers who require a precision 5-axis routing solution at part scales up to ten meters or more — where the gantry over-table architecture is the only practical means of providing full cutter access across the entire workpiece.

The G Series gantry structure features dual-column servo-driven travel on floor-mounted rails with real-time synchronization control to maintain beam squareness across the full X-axis stroke. The gantry beam carries a high-stiffness Z-axis ram fitted with Quintax's 5-axis A/C tilting spindle head, which provides ±120 degrees of A-axis rotation and continuous C-axis motion. This combination enables compound-angle trimming of contoured fuselage skins, deep draft angle routing of boat hull molds, and complex perimeter profiling of large wind turbine blade root shells and trailing edge assemblies without part repositioning.

Workholding on the G Series is accomplished through a configurable system of vacuum pods, T-slot extrusions, and peripheral clamp stations mounted on a phenolic or steel reference table. For aerospace tooling programs, the reference table can be shimmed and leveled to a precision datum plane, supporting the manufacture of jig-quality layup tools and check gauges. The Siemens Sinumerik 840D sl control, with full 5-axis RTCP and DXF/STEP import capability, provides the programming flexibility and CAM compatibility that aerospace production environments demand.

Applications for the G Series span aerospace composite tooling masters, large naval GFRP superstructure panels, racing and motorsport composite body molds, wind turbine blade molds and trim fixtures, and full-fuselage test fixture structures. Quintax's engineering team provides detailed installation planning, foundation design documentation, and factory acceptance testing prior to shipment, ensuring G Series installations meet the dimensional performance specifications required for aerospace production qualification.

Strengths & Limitations

Strengths

Gantry architecture with extended X-axis travel handles aerospace tooling masters and structural assemblies up to 12 meters long
A-axis range of ±120° combined with continuous C-axis gives full compound-angle access to contoured surfaces without repositioning
Dual synchronized gantry columns with real-time skew correction maintain positional accuracy across the full large-format envelope
Configurable vacuum pod and T-slot workholding system accommodates both flat panels and complex-planform aerospace tooling
Siemens 840D sl with RTCP provides full aerospace CAM compatibility and standard 5-axis program portability

Limitations

Very high capital cost and heavy facility infrastructure requirements restrict the G Series to well-capitalized aerospace and defense facilities
Large footprint and dual-column floor rails require a dedicated facility bay with precision-leveled concrete foundation
Lead times of 24–36 weeks from order to installation are common for custom-travel configurations

Best For

Aerospace tooling fabricators producing large 5-axis composite layup tools, autoclave mold masters, and jig structures Wind turbine blade manufacturers routing, trimming, and drilling large GFRP blade shells and root flange assemblies Naval defense contractors machining large GFRP and carbon fiber superstructure panels and sonar dome structures Racing and motorsport composite specialists producing full-scale body mold masters and aerodynamic surface tools

Frequently Asked Questions

01 What is the maximum practical part weight the Quintax G Series table can support?

The G Series reference table is engineered for distributed loads typical of large composite tooling — typically up to 5,000 kg evenly distributed across the table surface. Point loads from heavy tooling frames or steel reference fixtures should be assessed case-by-case with Quintax's engineering team during the application review phase.

02 How does the G Series achieve gantry squareness across a 12-meter X-axis?

Each gantry column is independently driven by a servo motor with a dedicated linear encoder. A synchronization controller compares column positions in real time and applies instantaneous corrections to maintain the beam perpendicular to the X-axis. This closed-loop synchronization operates at the CNC interpolation cycle rate, preventing the cumulative gantry skew that can occur with open-loop or poorly tuned dual-drive systems.

03 Can the G Series machine both foam tooling board and cured CFRP laminates?

Yes. The G Series spindle power range (15–22 kW) and spindle speed (up to 24,000 RPM) accommodate both the low-force, high-speed passes needed for foam and syntactic tooling board and the more demanding material removal in cured CFRP and fiberglass laminates. Tooling must be selected appropriately for each material — spiral router bits for foams and solid carbide or diamond-coated tools for composites.

04 Does Quintax provide factory acceptance testing (FAT) for the G Series?

Yes. Quintax conducts a full factory acceptance test at their Hudson, Ohio facility prior to shipment. The FAT includes volumetric accuracy verification of all linear and rotary axes using ballbar and laser tracker measurement, RTCP calibration verification, spindle run-out measurement, and demonstration of customer-specific test programs. FAT documentation is provided as part of the machine delivery package.

05 What ongoing calibration does the G Series require in service?

Quintax recommends annual volumetric calibration of the G Series using laser tracker or API Radian measurement to verify and correct axis geometry, squareness, and RTCP parameters. In addition to annual calibration, routine quarterly checks using ballbar on each axis and monthly lubrication and axis drive inspection are recommended per Quintax's maintenance schedule.
