About Yidai CNC Parts
Yidai CNC Parts is based in Shenzhen, China. Since 2015, we have focused on CNC rotary table applications, external 4th-axis retrofit solutions, matched controllers and probing accessories for machining centers.
Our practical goal is simple: help owners of capable 3-axis CNC machines add indexed rotary machining where an external solution is a better fit than a costly OEM axis expansion.
Our Shenzhen Office

Office address: Room 1101, Aiweipusi Building, No. 29, Guangyuan 2nd Road, Dongkeng Community, Fenghuang Street, Guangming District, Shenzhen, Guangdong Province, China.
What We Supply
- 4th-axis CNC rotary tables for indexing and multi-face machining.
- 5th-axis rotary tables for tilted and complex workpiece positioning.
- External single-axis controllers for cost-conscious 4th-axis retrofit projects.
- CNC touch probes for workpiece setting and tool probing workflows.
How We Approach CNC Retrofit Projects
Every machine is different. Before recommending a rotary table or controller, we check the machine model, CNC control, available working envelope, workpiece size, clamping method and required machining process. FANUC, Mitsubishi and Brother controls are commonly encountered, but exact signal and communication compatibility must always be confirmed for the individual machine.
External control can be a practical route for indexed operations, such as multi-face drilling, milling and positioning. For full simultaneous interpolation, the original CNC control and servo-axis architecture must be evaluated separately.
Start With the Right Information
For a focused recommendation, send your CNC machine make and model, control model, workpiece dimensions and a photo of the machine table or electrical cabinet. We will help identify the appropriate rotary table size, controller method and installation considerations.
