About Yidai CNC Parts

Yidai CNC Parts is based in Shenzhen, China. Since 2015, we have focused on CNC rotary table applications, external 4th/5th-axis retrofit solutions, matched servo control systems and probing accessories for machining centers.

Our practical goal is simple: help owners of capable 3-axis CNC machines add indexed rotary machining when an external solution is a better fit than a costly OEM axis expansion.

Core Servo Control Products for External 4th/5th-Axis Retrofits

The YD-1 first-generation split control package consists of an axis-card controller, a separate servo drive and a servo motor. It has no fixed servo power range: the motor and drive are selected according to rotary-table size, workpiece and fixture load, torque, speed, inertia, electrical-cabinet conditions and project requirements.

The CSD700 second-generation integrated controller-drive combines axis-card control and servo-drive functions in one unit. It supports matched servo systems from 400 W to 1 kW and must be paired with a suitable servo motor. It can be used for indexed 4th- or 5th-axis 3+1 and 3+2 retrofit projects.

What We Supply

• 4th-axis CNC rotary tables for indexing and multi-face machining.
• 5th-axis rotary tables for tilted positioning and complex multi-face machining.
• Standalone external 4th/5th-axis controllers for indexed retrofit projects.
• CNC touch probes and tool-setting accessories for workpiece alignment and tool measurement.

How We Approach CNC Retrofit Projects

Every machine is different. Before recommending a rotary table or controller, we check the machine model, CNC control, software version, available working envelope, workpiece size, clamping method and required machining process. FANUC, Mitsubishi, Brother and Siemens controls can be evaluated, but exact signal and communication compatibility must always be confirmed for the individual machine.

• FANUC and Mitsubishi: compatible configurations can retain the machine's original handwheel for rotary-axis setup and manual positioning.
• Brother and Siemens: an additional electronic handwheel is required for manual rotary-axis operation.

External control is intended for indexed 3+1 or 3+2 positioning, including multi-face drilling, milling and fixed-angle machining. Projects requiring full simultaneous interpolation, TCP or RTCP must be evaluated separately against the original CNC and native servo-axis architecture.

Start With the Right Information

For a focused recommendation, send the machine make and model, exact CNC control model and software version, workpiece dimensions, required machining process, and photos of the machine table and electrical cabinet. We will use this information to evaluate rotary-table size, controller architecture, handwheel method and installation conditions.
