Overview

The Quintax B Series is a bridge-style 5-axis CNC router built by Quintax Inc., an American manufacturer based in Hudson, Ohio, specializing in precision 5-axis routing for the aerospace, defense, and advanced composites industries. The B Series targets fabricators machining large composite laminates, cured fiberglass assemblies, and structural CFRP panels that require high-accuracy 5-axis trimming, drilling, and contouring across a broad work envelope. The bridge configuration — with a fixed table and a moving bridge carrying the 5-axis head — provides excellent part access and is well-suited to the flat-to-moderately-contoured composite panels typical of aerospace interior and secondary structure manufacturing.

The B Series bridge structure is fabricated from welded and stress-relieved steel with hardened linear guideways and precision ball-screw drives on all linear axes. The bridge design inherently stiffens the Y-axis travel compared to a gantry-over-table layout, which translates to improved cutter rigidity and better surface finish on contoured composite surfaces where cutting forces change direction continuously. The 5-axis spindle head provides A-axis tilt of ±115 degrees and continuous C-axis rotation, giving the cutter access to compound angles needed for beveled edge trimming, spar fitting holes, and access panel perimeter routing.

Quintax integrates a Siemens Sinumerik 840D sl or Heidenhain TNC 640 control into the B Series, providing full RTCP (Rotation Around Tool Center Point) for accurate 5-axis contouring with standard CAM post-processors. The machine's vacuum table system features independently controlled zones with a T-slot grid overlay for hybrid vacuum-and-clamp workholding, accommodating everything from full-sheet composite panels to smaller, irregular-planform parts. A high-capacity dust collection port and optional full enclosure package address the fiber particulate hazards associated with dry carbon fiber routing.

The B Series is used by aerospace interior suppliers producing overhead bin panels, sidewall trim, galley structures, and flooring, as well as by Tier 2 structural fabricators trimming wing access panels, fairings, and secondary structure skins. Quintax provides applications engineering support during machine selection, toolpath review, and post-processor validation, and offers a Quintax-certified technician service program for periodic calibration and spindle maintenance.

Strengths & Limitations

Strengths

Bridge architecture provides high Y-axis rigidity for consistent cutter engagement on large, flat composite laminates
Wide A-axis range of ±115° gives access to steeply beveled edges and undercut features on aircraft structural panels
Siemens 840D sl or Heidenhain TNC 640 control provides RTCP and full compatibility with aerospace CAM post-processors
Hybrid vacuum-and-T-slot table accommodates both full-sheet panels and irregular-planform composite parts in a single setup
Quintax applications engineering team supports post-processor validation and toolpath review for new composite programs

Limitations

Bridge configuration limits maximum workpiece height — tall or deep 3D composite structures may require gantry-style alternatives
American boutique manufacturer — longer spare parts lead times compared to European brands with North American parts depots
Premium pricing reflects custom engineering — budget entry models are not available in the Quintax catalog

Best For

Aerospace interior suppliers trimming, drilling, and routing large cured CFRP and fiberglass cabin panels and assemblies Tier 2 structural composite fabricators producing wing access panels, fairings, and secondary structure skins to tight tolerances Composite test specimen shops producing precision ASTM and FAA-standard coupon panels from CFRP laminates Defense aerostructure fabricators machining composite fuselage skin doublers, shear panels, and floor beam structures

Frequently Asked Questions

01 How does the Quintax B Series differ from the R Series?

The Quintax R Series is a router platform designed primarily for 3-axis and light 5-axis work on softer composite materials and patterns. The B Series is a heavier-duty bridge-style machine built specifically for demanding 5-axis simultaneous contouring in structural CFRP and fiberglass laminates, with a stiffer structure, wider A-axis range, and higher-end CNC control options.

02 Can the B Series drill fastener holes at compound angles in CFRP?

Yes. With RTCP enabled on the Siemens or Heidenhain control, the B Series can position the drill axis precisely perpendicular — or at a defined compound angle — to curved and angled composite surfaces. This is essential for producing on-axis fastener holes in structural CFRP skins and frames where hole perpendicularity directly affects joint strength.

03 What vacuum levels does the B Series table achieve?

The B Series vacuum system typically achieves 0.08–0.09 MPa (80–90% of atmospheric) at the table surface under a well-sealed workpiece. Each zone is independently controlled, allowing the operator to isolate active zones under the part footprint and prevent vacuum loss through open areas of the table grid. Zone pressure is monitored on the control display.

04 Does Quintax offer a full enclosure and dust collection system for the B Series?

Quintax offers an optional full enclosure package with negative-pressure extraction for shops routing dry carbon fiber and aramid materials. The enclosure integrates with a high-capacity HEPA-rated dust collector, maintaining particulate levels below OSHA action limits. This package is strongly recommended for facilities where operators work in close proximity to the machine during cutting operations.

05 What is the calibration and maintenance schedule for the B Series?

Quintax recommends annual certified calibration of all linear and rotary axes, including RTCP volumetric verification using a laser tracker or ballbar. Routine maintenance includes spindle bearing inspection, lubrication of linear guides and ball screws, and vacuum pump service per Quintax's maintenance manual intervals. Quintax-certified service technicians are available for on-site calibration and preventive maintenance visits.
