Engineering Advantage
The carbon fiber composite gantry on the COMAGRAV NOTUS PLUS is not a cosmetic upgrade — it fundamentally changes the dynamic behavior of the machine. Every performance metric that matters to industrial production is improved: acceleration, accuracy, vibration, thermal stability, and edge quality.
"COMAGRAV uses the highest quality fibers from Japan and coils them with high structural rigidity. In NOTUS PLUS the carbon fibre gantry saves 76.1 kg from moving parts, where it is most important. Deformation of the high speed gantry is 25% lower than deformation of standard steel gantry." — COMAGRAV Official Technical Documentation
Industrial routing is dominated by dynamic accuracy, not static rigidity. A lighter gantry changes direction faster without overshoot, delivering tighter corners, cleaner radii, and more accurate toolpaths at high speed. Steel gantries simply cannot match this because they carry too much inertia.
76.1 kg SavedCarbon fiber has 3–5× the stiffness-to-weight ratio of aluminum and significantly higher than steel. This means less bending during fast moves, less twist during heavy cuts, and more consistent Z-axis engagement — keeping the tool in the correct position even during aggressive routing.
3–5× vs AluminumCarbon fiber's higher natural frequency means less resonance, less chatter, and less vibration transfer into the spindle. The result is smoother edges, better finish on plastics, ACM, aluminum, and acrylic, and significantly longer tool life. This is one of the biggest contributors to superior cut edge quality.
No Chatter. No Scalloping.Carbon fiber expands approximately 10× less than aluminum. Long gantries drift with heat — aluminum grows and shrinks during long production runs. Carbon fiber stays dimensionally stable, ensuring better accuracy over long shifts, better registration on multi-pass jobs, and better consistency in hot production environments.
10× Less Thermal DriftTechnical Architecture
The COMAGRAV NOTUS PLUS carbon fiber gantry is manufactured using the highest-quality aerospace-grade carbon fiber from Japan, wound with precision to achieve maximum structural rigidity in the axes that matter most for CNC routing performance.
Carbon Fiber Composite Gantry Construction
COMAGRAV sources the highest-quality carbon fiber from Japan, wound with high structural rigidity to ensure consistent mechanical properties across the full gantry span.
The carbon fiber gantry achieves 25% lower deformation under load compared to a standard steel gantry of equivalent span — directly improving dimensional accuracy and repeatability.
The published mass reduction of 76.1 kg from the moving assembly is the primary driver of the machine's acceleration advantage. This is not an estimate — it is a COMAGRAV-verified engineering specification.
The carbon fiber technology allows COMAGRAV to build larger format machines — up to 5×5 meter working areas — without the weight penalty that would compromise acceleration and accuracy in steel or aluminum gantry designs.
Because the gantry is lighter, servo motors draw less current, run cooler, and experience less mechanical shock — reducing energy consumption and extending servo motor service life simultaneously. The carbon fiber gantry achieves high accelerations without requiring larger or more powerful servo motors.
The carbon fiber gantry is more rigid than a comparable steel gantry while weighing significantly less. This combination allows heavy-duty cutting applications — including aluminum, composites, and thick plastics — without the inertia penalty that limits steel-gantry machines at high acceleration.
COMAGRAV’s carbon fiber gantry upgrade delivers a step-change in machine performance — faster acceleration, better accuracy, lower wear — for a minimal cost premium over the standard steel gantry configuration. The productivity and longevity gains far outweigh the incremental investment.

Boat interior panels, composite cores, surfboards, kayaks, and RV and trailer panels. Large-format nesting of panels and high-speed trimming of composite assemblies are core NOTUS PLUS capabilities.
Composite and foam components, patterns, brackets, electrical panel plates, and covers. CNC routers are used for wind-turbine blade molds, edge-trimming, and aluminum and plastic parts in solar mounting systems.
Foam and wood patterns, molds, fixtures, and select plastic components and supports. Where devices involve plastic and composite plates, fixtures, or molds rather than hard-metal implants, the NOTUS PLUS is a capable platform.
Total Cost of Ownership
The carbon fiber gantry's performance advantages do not stop at cut quality. The reduced mechanical stress on every drive component in the machine translates directly into longer service intervals, fewer failures, and a lower total cost of ownership over the machine's operational life.
A heavy steel gantry slams into direction changes. A carbon fiber gantry glides through them. The reduced inertia means rails, bearings, and carriages last significantly longer — directly reducing maintenance cost over a 5–10 year operational period.
Because the gantry is lighter, servo motors run cooler, draw less current, and experience less mechanical shock during direction reversals. The result is longer servo life, fewer motor replacements, and lower energy consumption across every production shift.
High-mass gantries hammer belts, racks, and pinions with every direction change. The NOTUS PLUS carbon fiber gantry reduces that impact, extending belt life, reducing rack wear, and minimizing pinion wear — with fewer tensioning adjustments required.
Vibration kills spindles. Carbon fiber's vibration-damping properties reduce transmission into spindle bearings, tool holders, and collets — resulting in longer spindle life, fewer bearing failures, and better tool retention across all cutting operations.
Steel and aluminum gantries require frequent squaring, tram adjustments, and compensation tuning as they expand and contract with temperature. Carbon fiber's thermal stability reduces gantry twist, beam sag, and thermal drift — meaning less calibration work and more uptime.
Over a 5–10 year operational period, the carbon fiber gantry reduces parts cost, labor cost, and downtime cost. For industrial buyers running production shifts, this is a major differentiator that compounds in value with every year of operation.
