Why Add a 4th Axis to Your CNC Machine?
Adding a rotary axis dramatically expands what your CNC machine can do. A 4th axis allows parts to be indexed or rotated during machining, making it possible to machine multiple sides of a part in a single setup. This improves accuracy, reduces fixture changes, and saves valuable machining time.
With a CNC rotary table, operations such as cylindrical engraving, wrapped toolpaths, gear cutting, and complex multi-sided machining become easy to perform. Whether used for indexing or simultaneous multi-axis motion, a rotary axis increases productivity while opening the door to entirely new machining capabilities.
- Machine multiple sides of a part without refixturing
- Perform cylindrical engraving and wrapped toolpaths
- Improve accuracy by reducing setup changes
- Enable simultaneous 4-axis machining
- Increase productivity and reduce cycle times
Features of Centroid CNC Rotary Tables
Centroid rotary tables are designed for reliability, precision, and easy integration with modern CNC machines. Each unit is engineered to provide smooth rotary motion, accurate positioning, and long-term durability in demanding machining environments.
- Precision rotary motion for indexing or simultaneous 4-axis machining
- Automatic home switch for consistent repeatable referencing
- Pneumatic brake for rigid positioning during machining
- Compact designs suitable for mills, routers, and retrofit CNC machines
- Optional chuck and tailstock accessories for flexible workholding
- Available as complete servo packages or table-only configurations
These features make Centroid rotary tables an excellent solution for production machining, prototyping, and CNC retrofit applications.
Compatible CNC Control Systems
Centroid rotary tables are designed to work seamlessly with Centroid CNC control systems, providing smooth motion control, accurate positioning, and full support for indexing or simultaneous multi-axis machining.
Complete rotary packages are available with matched servo drives, motors, and cables for easy installation with the following Centroid control platforms:
- Allin1DC – Compact DC servo solution with integrated motion control
- Hickory – High-performance EtherCAT motion control platform
- Oak – Industrial-grade CNC control system used on advanced machines
- Acorn/AcornSix – User provided Step and Direction AC Servo, order the "Table Only" option when using with Acorn or AcornSix
With matched hardware and proven CNC software, Centroid rotary systems are easy to install, reliable to operate, and capable of delivering true multi-axis machining performance.
Use Your Own Servo Motor and Drive
Centroid rotary tables can also be supplied as a table-only configuration, allowing machine builders, integrators, and advanced users to pair the rotary axis with their own servo motor and drive system. This option provides maximum flexibility for custom CNC machines and specialized control systems.
By supplying your own servo hardware, the rotary table can be integrated into virtually any CNC control platform that supports a rotary axis. This makes Centroid rotary tables a practical solution for OEM machine builders, retrofit projects, research systems, and other custom CNC applications.
- Available without servo motor, drive, or cables
- Ideal for OEM machine builders and custom CNC integrations
- Compatible with a wide range of servo motor and drive systems
- Integrates with many CNC controls that support a rotary axis
- Two output shaft options available to match common servo couplings
Whether you are building a custom machine or integrating the rotary axis into an existing CNC platform, the table-only option provides the freedom to choose the motion hardware that best fits your system requirements.
