Product Description
Customized Zero Backlash 6 Axis Robot Joint Flange Shaft Kits with Hollow Design
Product Overview

We provide full custom manufacturing of robot joint components based on your drawings, 3D models or sample parts. The product line covers three core categories: Robot Joint Output Flange, Joint Drive Shaft & Hollow Shaft, and Connecting Sleeve, Spacer & Coupling Hub, all precision machined on Mazak INTEGREX i-200S turn-mill composite machining centers.

All turning, milling, drilling and feature machining operations are completed in a single clamping setup to eliminate secondary positioning errors and deliver micron-level dimensional accuracy.

Crafted from premium 6061-T6 / 7075-T6 aluminum alloy, these custom joint parts deliver excellent strength-to-weight ratio, high structural rigidity and stable assembly performance. They are purpose-built for J1-J6 axes of 6-axis industrial robots, collaborative robots and precision automation systems. From prototype validation to high-volume production, we support full customization with complete quality traceability.

Product Details
Robot Joint Output Flange
Designed for J1-J6 joints of 6-axis robots, the output flange is fully formed in a single Mazak turn-mill setup. It features evenly distributed inclined mounting holes around the circumference, an integrated sealing groove for reliable dust and oil protection, and a high-precision positioning stop for accurate joint alignment. The flat and precise end face flange ensures rigid bolted connection and consistent load transfer across the joint interface.
Joint Drive Shaft & Hollow Shaft
The drive shaft adopts a hollow rotary design that allows robot cables and signal wires to route internally through the joint axis. The part integrates radial and angled oil holes for internal lubrication, a precision keyway for torque transmission, and a flat section for easy assembly and anti-rotation positioning. All inner bore, outer diameter and cross features are machined in one setup, guaranteeing perfect concentricity and smooth rotary performance.
Connecting Sleeve, Spacer & Coupling Hub
This category includes three types of joint connecting components: connecting sleeves, spacers and coupling hubs. Each part combines precision rotary turning with side milling flats for circumferential positioning, plus accurately located positioning holes and mounting holes for repeatable assembly. Manufactured on Mazak turn-mill centers in a single clamping, these parts deliver consistent perpendicularity between end faces and inner bores for stable joint stacking and alignment.

All components are manufactured on Mazak INTEGREX i-200S machines using a one-setup turn-mill compound process. This eliminates cumulative positioning errors from re-fixturing, ensuring perfect concentricity, perpendicularity and hole position accuracy across every functional surface for consistent assembly interchangeability.

Product Advantages
1. Mazak One-Setup Turn-Mill Precision
All turning, milling, drilling and feature machining are completed in a single clamping on Mazak INTEGREX i-200S turn-mill centers. This eliminates repositioning errors between operations and delivers exceptional concentricity, perpendicularity and hole position accuracy that cannot be achieved with conventional separate turning and milling processes.
2. Fully Customized to Exact Robot Requirements
We produce strictly according to your drawings, 3D models or sample parts. Material grade, dimensional specifications, sealing groove form, cable routing bore size and mounting hole layout can all be fully customized to match the unique requirements of different robot brands and joint axes.
3. Lightweight High-Strength Aluminum Construction
Manufactured from 6061-T6 or 7075-T6 aerospace-grade aluminum alloy, these components deliver outstanding structural rigidity while significantly reducing joint weight. This lowers robot joint load, improves dynamic response speed and enhances overall operating energy efficiency.
4. Integrated Multi-Functional Design
All components integrate multiple functional features into one piece: the output flange combines sealing and positioning functions; the hollow shaft enables power transmission and cable routing in one body; connecting sleeves feature side milled anti-rotation flats, eliminating the need for extra positioning parts.
5. DFM Support & Scalable Production
Our engineering team provides professional DFM feedback to optimize part geometry, improve manufacturability and reduce production cost. From single-piece prototype validation to high-volume mass production, all parts are produced with identical Mazak machine tool paths and process parameters for consistent batch-to-batch quality.
Application Scenarios

FAQ
Q1: Can you produce robot joint parts according to our own drawings?
A: Yes, we provide full custom manufacturing services based on customer 2D drawings, 3D CAD models or physical sample parts. All dimensions, materials and functional features can be tailored exactly to your specific robot joint requirements.
Q2: What equipment do you use to machine these aluminum robot joint components?
A: All our robot joint components are manufactured on Mazak INTEGREX i-200S turn-mill composite machining centers. This 5-axis turn-mill technology allows us to complete all turning, milling, drilling and feature machining in a single setup, ensuring exceptional concentricity and geometric accuracy.
Q3: What aluminum alloys are available for robot joint parts?
A: We commonly use 6061-T6 and 7075-T6 aluminum alloys for robot joint components, selected for their excellent strength-to-weight ratio and machinability. We can also source custom aluminum grades and heat treatments to match your specific performance and certification requirements.
Q4: What is the purpose of the hollow shaft design for robot joints?
A: The hollow shaft design allows internal routing of robot cables, pneumatic lines and signal wires through the joint axis. This creates a clean, protected cable path, reduces external wear and enables more compact joint design with smoother unrestricted rotary motion.
Q5: What is the minimum order quantity for custom robot joint components?
A: We accept orders as low as 1 piece for prototype and validation purposes. Prototype orders typically ship within 3-7 working days and include full dimensional inspection reports and material traceability documentation.
