Complete CNC Rotary Axis Retrofit Package

A complete project package for manufacturers that want to add indexed 4th-axis or 5th-axis capability to an existing 3-axis CNC machine. Yidai matches the rotary table, servo control architecture, motor, brake circuit, cables and machine interface as one system.

Application boundary: this package is primarily intended for indexed 3+1 or 3+2 positioning, multi-face machining and fixed-angle operations. Continuous simultaneous X/Y/Z/A or five-axis interpolation requires a separate native-axis architecture review.

What a Complete Package Can Include

System area Typical supply scope What must be confirmed
Rotary unit 4th-axis rotary table or 5th-axis tilt-rotary table Workpiece envelope, fixture, load, cutting torque, center height, travel and clearance
External control YD-1 matched servo control package or CSD700 integrated controller-drive system CNC model, software version, TCP/IP, RS232 or I/O method and operating sequence
Servo and feedback Matched servo motor, encoder and drive/control parameters Reduction ratio, inertia, speed, torque, brake and positioning target
Machine interface Control cables, ready/in-position/alarm coordination and brake/clamp logic Electrical drawings, cabinet space, safety circuits and machine-builder PLC/PMC logic
Project support Selection review, wiring guidance, parameter support, remote commissioning and acceptance checklist Local installation responsibility, time zone, language and service scope

Choose the Correct Project Route

Complete 4th-Axis Package

For indexed side drilling, milling, bolt circles, radial features and multi-face machining around one rotary axis.

Complete Indexed 5th-Axis Package

For 3+2 positioning, angled holes and multi-angle access where the workpiece is positioned before cutting resumes.

Probe Add-On

Workpiece probes and tool setters can be evaluated separately to improve datum setting, alignment and tool measurement.

How a Retrofit Project Is Evaluated

1. Machine reviewConfirm the machine model, CNC control, software version, table load and working envelope.
2. Process reviewCheck the workpiece, fixture, cutting features, required angles and accuracy target.
3. System matchingSelect the rotary table, YD-1 or CSD700 architecture, servo size and brake method.
4. Interface reviewDefine TCP/IP, RS232 or I/O communication, signals, interlocks and cabinet layout.
5. ProposalIssue a project-specific supply scope, technical assumptions, responsibilities and quotation.

Information Required Before Quotation

Machine and CNC

Machine builder and model, full CNC model, software/version screen, table size, travel, spindle clearance and allowable load.

Workpiece and Process

Dimensions, weight, center of gravity, fixture, required positions, cutting features, accuracy and cycle sequence.

Electrical and Interface

Cabinet photos, wiring drawings when available, Ethernet/serial/I/O resources, M-code sequence and safety requirements.

Complete CNC Retrofit Package FAQs

What is included in a complete CNC rotary-axis retrofit package?

The typical scope can include a 4th-axis rotary table or indexed 5th-axis tilt-rotary table, a matched YD-1 or CSD700 control system, servo motor, brake circuit, cables, interface signals and project support. Final supply scope depends on the exact machine and process.

Is this a simultaneous 4- or 5-axis system?

No. These packages are primarily for indexed 3+1 or 3+2 machining. Projects requiring continuous simultaneous interpolation or TCP/RTCP need a separate native CNC-axis architecture review.

What information is needed before quotation?

Provide the machine builder and model, exact CNC control and software version, table space and travel, workpiece and fixture details, required angles and operations, plus electrical-cabinet and interface information.
