Our CNC machined robot structural part joint connecting tube is
precision engineered for industrial robot and collaborative robot
applications where angular offset connection, load transmission,
and structural elegance are critical. Each connecting tube is
manufactured on advanced 5-axis CNC machining centers, maintaining
tolerances as tight as +/-0.01mm to ensure proper flange alignment,
smooth force transmission, and consistent performance in demanding
robotic applications.
This robot structural part features an elegant S-shape curved
design with large circular flanges at both ends equipped with
multiple uniformly distributed mounting holes for joint bearing
integration. The hollow tube construction provides exceptional
strength-to-weight ratio while the streamlined curved profile
enables angular offset between connected joints. Our 5-axis CNC
capabilities enable complex geometries including continuous curved
surfaces, precise flange machining, and accurately positioned
mounting features - 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 robot connecting
tube applications. The material provides rigid yet lightweight
structures that minimize robot arm mass while maintaining
operational precision under dynamic loads. The hollow tube design
optimizes material usage while preserving structural rigidity for
heavy-duty robot operations. 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. Each robot
structural part joint connecting tube undergoes comprehensive
dimensional inspection using coordinate measuring machines to
verify flange concentricity, curved surface accuracy, wall
thickness uniformity, and geometric tolerances. Surface finish and
material properties are verified to ensure specifications are met.
Complete inspection reports and material certificates are provided
with every shipment.
These precision robot structural part joint connecting tubes serve
applications across industrial robot elbow connections,
collaborative robot angular offset links, automated machinery
curved connectors, pick-and-place robot S-shape arms, CNC machine
tool articulated connections, precision automation equipment curved
linkages, semiconductor handling robot offset joints, and medical
robot aesthetic connecting arms. They function as critical
structural parts that connect robot joints with angular offset,
transmit loads through curved paths, and provide elegant mechanical
solutions.

FAQ
Q: What connecting tube sizes can you manufacture?
A: We manufacture robot structural part joint connecting tubes from
small collaborative robot links to large industrial robot arms. Our
5-axis CNC capabilities accommodate flange diameters from 50mm to
200mm with custom S-curve profiles and tube lengths based on your
requirements.
Q: What angular offsets can your S-shape tubes accommodate?
A: Our S-shape connecting tubes can accommodate various angular
offsets depending on design, typically ranging from 15 degrees to
45 degrees. We optimize the S-curve profile to achieve the desired
offset while maintaining structural integrity and load capacity.
Q: What materials do you recommend for robot connecting tubes?
A: We recommend 6061-T6 aluminum for most robot structural part
joint connecting tube applications due to its excellent
strength-to-weight ratio and machinability. For ultra-lightweight
applications, we offer carbon fiber composite options.
Q: Can you customize the S-curve profile?
A: Yes, we specialize in customizing S-curve profiles including
curve radius, offset angle, and tube diameter. Our DFM team
optimizes designs for your specific space constraints, load
requirements, and aesthetic preferences.
Q: What tolerances can you achieve on curved surfaces?
A: We achieve curved surface profile tolerances within 0.05mm and
flange concentricity within 0.02mm with 5-axis simultaneous
machining. These tight tolerances ensure proper assembly and smooth
operation.
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.
