RTA-170

RTA-170 CNC Rotary Table for External 4th Axis Retrofit

The RTA-170 is a compact single-axis CNC rotary table with a 170 mm worktable for adding indexed 4th-axis capability to existing 3-axis machining centers. It is a practical choice for multi-face machining, radial holes, bolt circles and repeated angular positioning where manual re-clamping reduces efficiency and consistency.

For retrofit projects, the rotary table can be evaluated together with an external axis controller, servo system and CNC communication method. This approach is intended for machines where enabling an OEM fourth axis is not economical or is not available.

Key Specifications

How to Select an RTA-170 Retrofit Package

• Confirm the machine table space, X/Y/Z travel and spindle clearance.
• Provide the workpiece size, weight, fixture height and required indexing angles.
• Confirm the CNC system and available interface, such as RS232 or I/O triggering.
• Match the rotary table with the appropriate external controller, servo and brake control.

Frequently Asked Questions

Can RTA-170 be used on a 3-axis CNC machine? Yes. It can be used as part of an external 4th-axis retrofit package when the machine layout, control method and application are evaluated first.

Does this require changing the CNC PLC program? The exact integration method depends on the CNC system and controller package. Send the CNC model and electrical cabinet details for a compatibility check before ordering.
