Overview

The Thermwood Model 90 is a heavy-duty 5-axis CNC router purpose-built for large-format aerospace composite machining. Manufactured in Dale, Indiana, Thermwood has been building industrial CNC routers since 1969 and the Model 90 sits at the top of their gantry router product line. It is engineered to trim, drill, and contour carbon fiber reinforced polymer (CFRP), fiberglass, Kevlar, and honeycomb sandwich panels found in aircraft fuselage skins, wing covers, nacelles, and bulkheads — applications where part size routinely exceeds what a machining center can handle.

The Model 90 uses a moving-gantry architecture with a fixed table, which keeps the part stationary and allows the gantry to traverse the full working envelope without moving the workpiece. This matters enormously on large aerospace composites that are difficult to reposition mid-operation. The A/C-axis 5-axis head provides full simultaneous 5-axis motion, allowing the spindle to follow complex compound-curved surfaces for trimming and drilling at the correct angle-to-surface vector — a requirement for countersunk fastener holes in aircraft structure.

Thermwood builds the Model 90 with a welded steel frame, precision-ground ball screws, and servo drives throughout. The dust collection system is sized for composite routing, where fine carbon fiber particles require high-efficiency extraction to protect both the machine and the operators. Thermwood also offers their SMART (Simplified Machine Automation and Robotics Technology) control system, which integrates well with aerospace programming environments and provides real-time adaptive controls.

Pricing for the Model 90 is configured to customer requirements and Thermwood quotes on a project basis. Table sizes range from approximately 5 x 10 ft to very large custom configurations, and the machine can be integrated into automated cell layouts with pallet changers or robotic loading. Thermwood's domestic manufacturing and strong North American service network make the Model 90 a practical choice for aerospace OEMs and Tier 1 suppliers who cannot afford extended downtime on production composite trimming operations.

Strengths & Limitations

Strengths

Full simultaneous 5-axis motion with A/C-axis head enables correct angle-to-surface trimming and drilling on compound-curved aerospace panels
Moving-gantry fixed-table design keeps large fragile composite parts stationary throughout the cut cycle, eliminating repositioning errors
Thermwood's domestic US manufacturing and North American service network provide fast on-site support critical for aerospace production environments
24,000 RPM HSK-63F spindle with high-flow dust collection optimized for carbon fiber, fiberglass, and Kevlar without delamination

Limitations

Pricing is configured-to-order and can exceed $500,000 for large-format or heavily optioned machines, requiring capital budget approval at most aerospace OEMs
The moving-gantry architecture limits dynamic rigidity compared to fixed-bridge machining centers, making the Model 90 unsuitable for hard-metal milling
Large footprint and facility requirements (dust extraction, vacuum fixturing, compressed air) add significant installation costs beyond the machine purchase price

Best For

Aerospace Tier 1 and OEM shops trimming, drilling, and routing CFRP fuselage skins, wing panels, nacelles, and composite bulkheads Defense contractors machining large fiberglass and Kevlar radomes, fairings, and structural composites that exceed the envelope of conventional machining centers Marine composite fabricators producing large hull panels, decks, and structural laminates in fiberglass and carbon fiber Wind energy manufacturers routing and trimming large fiberglass blade root sections and spar components

Frequently Asked Questions

01 What materials can the Thermwood Model 90 cut?

The Model 90 is optimized for composite materials including carbon fiber reinforced polymer (CFRP), fiberglass, Kevlar/aramid, honeycomb core sandwich panels, foam core laminates, and pre-preg materials. It can also rout aluminum sheet and plate at moderate rates. It is not designed for hard-metal milling applications like steel or titanium.

02 How does the Model 90 hold composite panels during machining?

Thermwood offers integrated vacuum fixturing tables that hold composite panels without mechanical clamps that could damage or distort the part. Vacuum zone layouts are configurable to match specific part families. For very large assemblies, custom fixture frames are designed as part of the installation.

03 What control system does the Thermwood Model 90 use?

The Model 90 uses Thermwood's proprietary SMART Control system, which is built on a Fanuc motion control foundation. It supports standard G-code and integrates with major CAM packages including Mastercam, Siemens NX, and Catia-based aerospace toolpath environments. The control includes Thermwood's Cut Ready programming system for simplified operation.

04 How does the Model 90 compare to European 5-axis composite routers?

Compared to European machines like the CMS Poseidon or Breton Ultrix, the Model 90 competes on domestic US support, lead time, and familiarity with American aerospace production standards. European machines often offer higher structural rigidity for mixed composite-aluminum applications, while Thermwood's advantage is its established aerospace customer base, domestic service network, and knowledge of FAA-relevant quality documentation requirements.

05 Can the Thermwood Model 90 be integrated into an automated cell?

Yes. Thermwood designs the Model 90 for cell integration including conveyor loading systems, robotic part handling, and pallet changers for lights-out or reduced-labor composite trimming operations. Thermwood also develops their own additive manufacturing platforms (LSAM) and the Model 90 can be positioned alongside LSAM systems in a print-then-machine workflow for large composite structures.
