Side-hole drilling and milling
Index the workpiece to different angles and reduce repeated clamping on manual fixtures.
External 4th and 5th axis retrofit
External 4th & 5th Axis Retrofit for 3-Axis CNC Machines
Add indexed rotary-axis capability to supported FANUC, Mitsubishi and Brother CNC machines. On compatible TCP/IP integrations, operators can use the machine's original handwheel instead of a separate MPG.
FANUC, Mitsubishi & Brother
Machine-specific compatibility is checked before the rotary table and controller are selected.
Native handwheel control
Supported TCP/IP integrations use the CNC machine's original handwheel, with no separate MPG required.
40%-50% of OEM cost
External-axis projects can cut investment by 50% or more, depending on machine and scope.
The rotary table works inside the machine enclosure. Compact external control hardware is installed in the CNC electrical cabinet.

OEM Axis Expansion vs External Indexed-Axis Retrofit
Many factories own capable 3-axis CNC machines. A matched external rotary-axis system can add indexed multi-face machining at typically 40%-50% of the cost of an OEM additional-axis package.
Original servo expansion
- Higher cost
- Depends on CNC system and machine brand
- Often requires service from original supplier
- Better for full simultaneous control when required
External axis retrofit
- Typically 40%-50% of OEM upgrade cost
- Good for indexing and many 4th axis jobs
- TCP/IP, RS232 and I/O integration options
- Native CNC handwheel control on supported configurations
Common Applications
Typical indexed rotary applications for manufacturers upgrading reliable 3-axis CNC machines.
Batch parts on older CNC machines
Improve the usefulness of existing equipment without the budget pressure of a new machining center.
Native handwheel rotary positioning
On supported TCP/IP configurations, the original CNC handwheel can jog the rotary axis without a separate pendant.
