Tetra 4 Axis CNC Router
A multiple-use 4-axis CNC router designed for advanced machining, creative production and complex routed components.
The Tetra adds rotary or angular 4th-axis capability to the traditional X, Y and Z movement of a CNC router. This gives workshops greater flexibility when producing intricate designs, cylindrical work, complex shapes and parts that require more than standard 3-axis machining.
More Flexibility Than Standard 3-Axis Routing
The Tetra 4 Axis CNC Router is built for workshops that need more than flat-bed cutting. By adding an A-axis or C-axis capability, the machine can approach the workpiece from additional angles, helping users create more intricate shapes, contours, rotary work and complex production parts.
This makes the Tetra a strong option for manufacturers working with detailed components, cylindrical parts, specialist profiles, creative production, aerospace-style applications, medical-style precision work and advanced routed designs.
Built for Intricate Designs, Rotary Work and Complex Geometry
The Tetra gives workshops the ability to machine from additional angles, improve workflow and reduce the need for repeated manual repositioning on more complex workpieces.
What makes the Tetra a 4-axis CNC router?
A standard 3-axis CNC router moves across X, Y and Z. The Tetra adds a fourth rotational or angular axis, often referred to as the A-axis or C-axis, so the cutting strategy can support more advanced machining and component manipulation.
Multi-Axis Machining
The fourth axis enables more complex machining operations compared with standard 3-axis routing.
Enhanced Precision
Approaching work from additional angles can reduce repeated setups and help maintain accuracy on detailed parts.
Complex Geometry
Useful for intricate forms, contoured surfaces, undercuts and complex 3D shapes that are difficult with flat 3-axis machining.
Reduced Tool Wear
Multi-axis strategies can help distribute cutting loads more evenly, supporting tool life and production consistency.
Versatile Tooling
Tools can be positioned at different angles to support different cutting strategies and material requirements.
Improved Workflow
More complex tasks can be completed with less manual intervention, helping streamline production for specialist work.
A-axis, C-axis and rotary options explained
The Tetra can be configured around different fourth-axis requirements, depending on whether the application needs angular movement, rotational movement, or cylindrical workholding.
A-axis angular machining
The angular A-axis helps provide multi-axis machining, supporting intricate and complex workpiece manipulation.
C-axis rotational machining
The C-axis provides rotational movement around the Z-axis, giving additional flexibility for precision machining.
Fixed and portable rotaries
Rotary devices can be used for cylindrical pieces, including specialist timber work and staircase-style components.
Specialist production support
The Opus team can help advise whether your parts are better suited to A-axis, C-axis or rotary 4-axis machining.
