Overview
The Anderson Pro 300 is a 5-axis industrial CNC router engineered for aerospace composite fabrication, targeting Tier 1 and Tier 2 aerospace suppliers that require a rigid, high-accuracy routing platform for CFRP, fiberglass, and mixed composite assemblies. Anderson America Corp. positions the Pro 300 as a production-grade machine capable of handling the full range of aerospace composite trimming, drilling, and contoured routing operations that define structural component fabrication at commercial and defense aerospace suppliers.
The Pro 300 features a heavy fabricated steel gantry structure with precision linear guide rails on all axes, providing the static and dynamic rigidity needed to maintain dimensional accuracy while routing abrasive carbon fiber materials. The 5-axis electrospindle head delivers full A and C axis rotation with RTCP (Rotating Tool Center Point) compensation, enabling simultaneous 5-axis contouring across compound-curved aerospace surfaces. The machine's working envelope is sized to accommodate the wing rib sections, fuselage frame panels, and nacelle components that define the Pro 300's core aerospace applications.
In production environments, the Pro 300 handles dry routing of thermoset and thermoplastic composites, automated drilling sequences for fastener patterns, and precision trimming of composite panels to net shape. Integrated vacuum workholding holds composite workpieces securely without mechanical clamping that would damage surface plies, and the machine's automatic tool changer enables multi-operation cycles without manual intervention. Dust extraction is critical in composite routing environments and Anderson provides integration provisions for industrial extraction systems.
The Pro 300 is available with Siemens Sinumerik or Anderson's proprietary control interface, allowing aerospace customers to align with their CAM and post-processor standardization. Anderson's US-based service organization supports the Pro 300 in production facilities, providing the technical response capability that aerospace manufacturing environments require when unplanned downtime directly impacts production delivery commitments.

Strengths & Limitations
Strengths
- Full simultaneous 5-axis capability with RTCP enables drill-normal fastener patterns and compound-surface contouring on aerospace composite assemblies without repositioning
- HSK-63F spindle interface provides rigid tool clamping and repeatable tool change accuracy essential for maintaining hole position tolerances across large aerospace composite panels
- Siemens Sinumerik 840D sl control option ensures compatibility with standard aerospace CAM environments and post-processors used at Tier 1 aerospace suppliers
- US-manufactured machine with domestic service organization meets domestic sourcing preferences for aerospace and defense procurement programs
- Integrated vacuum workholding provisions and dust extraction compatibility make the Pro 300 suitable for full production composite routing cells without extensive ancillary infrastructure
Limitations
- Anderson has lower brand recognition in the aerospace composite router segment compared to Thermwood or Onsrud, requiring more extensive evaluation and reference checking during procurement qualification
- The Pro 300's working envelope is mid-range and may not accommodate the largest fuselage skin panels or spar structures that require custom-format machines from other suppliers
- Proprietary control option limits post-processor availability and operator cross-training opportunities compared to standard Siemens or Heidenhain platforms

Frequently Asked Questions
01
The Anderson Pro 300 is designed to route thermoset composites (CFRP, fiberglass, Kevlar), thermoplastic composites, foam core sandwich panels, and aluminum composite panel (ACP). It handles the full range of aerospace structural composite materials. For highly abrasive carbon fiber, diamond-coated tooling is recommended to achieve acceptable tool life in production environments.
02
The Anderson Pro 300 supports full simultaneous 5-axis contouring with RTCP (Rotating Tool Center Point) compensation active. This enables the machine to follow compound-curved composite surfaces continuously, which is required for aerospace panel trimming and ply boundary routing on complex-geometry structural assemblies. 3+2 indexed positioning is also available for simpler operations.
03
The Pro 300 is offered with Siemens Sinumerik 840D sl or Anderson's proprietary control system. Aerospace customers typically specify the Siemens Sinumerik 840D sl for compatibility with established post-processors and operator familiarity in aerospace manufacturing environments. Anderson's proprietary control is an option for customers seeking a simplified operator interface.
04
Both machines target aerospace composite routing with 5-axis capability. Thermwood has a longer established history in aerospace composite routing and broader name recognition in US Tier 1 facilities. The Anderson Pro 300 may offer competitive pricing and similar technical specifications. Procurement decisions typically turn on total cost of ownership, service proximity, lead time, and the commercial relationship each manufacturer can provide.
05
The Anderson Pro 300 supports integrated vacuum workholding as the primary method for composite panel fixturing, avoiding mechanical clamping that can damage surface plies or cause delamination. Anderson provides vacuum zone configurations matched to the part family. Custom fixture tooling plates and MDF vacuum subplates are compatible with the machine's table interface for specialized part geometries.
