Product Description
Detailed Specifications & Features

Our CNC machined robot structural part arm linkage is precision engineered for industrial robot and collaborative robot applications where inter-joint connection, lightweight construction, and dynamic load capacity are critical. Each joint connecting arm is manufactured on advanced 4-axis and 5-axis CNC machining centers, maintaining tolerances as tight as +/-0.01mm to ensure proper joint alignment, reliable load transfer, and consistent performance in demanding robotic applications.

As a key robot structural part, this arm linkage features dual circular bearing housings at each end with bolt hole arrays for bearing and joint assembly, integrated weight reduction holes for optimal mass distribution, and a precision central bridge section for rigid inter-joint connection. Our multi-axis CNC capabilities enable complex geometries including concentric bores, precisely positioned threaded holes, and intricate weight reduction patterns - all machined from solid aluminum billets for maximum structural integrity.

This structural part is manufactured from aerospace-grade aluminum alloy 6061-T6, selected for its exceptional strength-to-weight ratio, stiffness, and machinability essential for heavy-duty robotic applications. The material provides rigid yet lightweight structures that minimize robot arm inertia while maintaining operational precision under dynamic cyclic loads. The weight reduction hole pattern optimizes mass while preserving structural integrity. Mirror-polished surface finish achieves Ra 0.4-0.8um.

Our ISO 9001:2015 certified quality management system ensures consistent quality across every production run following GB/T 1804-2000 standard with strict tolerance control verified using precision measuring instruments including Mitutoyo dial indicators. Each robot structural part arm linkage undergoes comprehensive dimensional inspection using coordinate measuring machines to verify bearing bore concentricity, bolt hole positions, weight reduction hole patterns, and geometric tolerances. Complete inspection reports and material certificates are provided with every shipment.

These precision robot structural part arm linkages serve applications across industrial robot upper arm to forearm connections, collaborative robot joint to joint linkages, automated machinery connecting arms, pick-and-place robot arm extensions, CNC machine tool structural arms, precision automation equipment linkages, semiconductor handling robot arm components, and medical robot structural arms. They function as critical inter-joint structural parts that connect robot joints, transfer loads, and enable smooth articulation across multiple axes.

We support your complete robotic product development cycle with flexible manufacturing options from prototype to mass production. Validate designs with rapid prototypes for fit and function testing, refine through small batch testing for performance validation, and scale to high-volume production for commercial robot manufacturing. Our experienced engineering team provides DFM feedback to optimize designs for manufacturability, weight, and cost. Fast delivery and consistent quality ensure customer satisfaction.

FAQ
Q: What arm linkage sizes can you manufacture?
A: We manufacture robot structural part arm linkages from small precision robot arms to large industrial robot structural linkages. Our 5-axis CNC capabilities accommodate bearing housing diameters from 50mm to 300mm with custom arm lengths and weight reduction patterns based on your requirements.
Q: What materials do you recommend for robot arm linkages?
A: We recommend 6061-T6 aluminum for most robot structural part arm linkage applications due to its excellent strength-to-weight ratio and machinability. For heavy-duty applications, we offer 7075-T6 aluminum and various carbon fiber composite options.
Q: Can you optimize weight reduction patterns?
A: Yes, we specialize in optimizing weight reduction hole patterns based on FEA analysis to maintain structural integrity while minimizing mass. Our DFM team works closely with customers to achieve the optimal strength-to-weight ratio for each robot structural part design.
Q: What tolerances can you achieve on bearing bores?
A: We achieve H7 bearing bore tolerances within +/-0.01mm with surface roughness Ra 0.4-0.8um. For critical features, we can achieve tolerances down to 0.005mm following GB/T 1804-2000 standard, verified with Mitutoyo precision measuring instruments.
Q: What is your typical lead time?
A: Prototype samples: 5-10 days. Small batch (10-100 pcs): 2-3 weeks. Medium batch (100-1000 pcs): 3-5 weeks. Large production (1000+ pcs): 5-8 weeks. Fast delivery and consistent quality ensure high customer satisfaction.
Q: Can you support both prototypes and mass production?
A: Yes, we offer flexible manufacturing from single prototypes for design validation through to high-volume production runs. Our processes maintain quality and consistency across all production volumes with fast turnaround times.
