Robotics Material Guide
High stiffness-to-weight ratio and dimensional stability are the primary drivers for robotics material selection.
Aluminium 6061-T6
The dominant robotics structural material. Excellent stiffness-to-weight, great machinability, responds well to anodising. Used for arm links, frames, end effectors, and housings.
Aluminium 7075-T6
40% stronger than 6061 at similar weight. Used for highest-stress structural joints in heavy-payload robots and premium cobots.
4140 / 4340 Steel
For gearbox components, shafts, and high-load structural interfaces. Higher stiffness than aluminium where deflection must be minimised.
Titanium Ti-6Al-4V
Used in premium robots where minimum weight is essential. Excellent fatigue resistance for cyclic loading in robot joints.
PEEK
High-performance engineering plastic for bushings, thrust washers, and components where both low weight and moderate mechanical properties are required.
Delrin (POM)
Self-lubricating wear surface for low-load applications, cable management, and protective covers. Easy to machine, dimensionally stable.
Robotics CNC Machining FAQ
What robotics and automation components can be CNC machined?
Robotics and automation systems require a wide variety of precision machined components: robot arm structural members (links, shoulders, elbow joints), end effector bodies and tool changers, gearbox and harmonic drive housings, servo motor mounts and couplings, linear actuator bodies and end caps, cable management brackets and conduit fittings, base plates and mounting frames, encoder housings and sensor mounts, and custom jigs and fixtures for robotic assembly systems. Both prototype development components and production batch orders are within scope.
What materials are used for CNC machined robotics components?
Material selection in robotics is driven by the need for high stiffness-to-weight ratio, dimensional stability, and machinability. Aluminium 6061-T6 is the most common robotics material — used for structural frames, housings, and brackets where weight is critical. Aluminium 7075-T6 is used for highest-stress structural members. 4140 and 4340 steel is used for gearbox components, shafts, and high-load structural elements. Titanium Ti-6Al-4V is used for weight-critical structural joints in premium cobots and industrial robots. Engineering plastics (PEEK, Delrin, Nylon PA6) are used for bushings, wear components, and non-structural elements.
How tight are the tolerances required for robotics CNC parts?
Tolerance requirements vary by component function. Structural robot arm members typically require ±0.05mm on mounting features. Bearing and shaft interfaces require ±0.01mm or H6/h6 fits. Harmonic drive housing bores require very tight tolerances — typically ±0.005mm or better — to maintain positional accuracy under load. Encoder mounting faces require flatness tolerances of 0.01mm or better to ensure accurate feedback. We manufacture to your drawing callouts, and our DFM review flags any features that are difficult or costly to achieve before manufacturing begins.
Can you supply components for collaborative robots (cobots)?
Yes. Collaborative robot developers and cobot integrators require precision machined structural components, end effector tooling, and custom mounting hardware. Cobots place particular emphasis on low weight (to maximise payload relative to robot weight) and precise geometry (to maintain TCP accuracy). Rapid Manufacturing is well-suited to the iterative prototyping and small-batch production cycles typical of cobot development — no minimum order, fast quote turnaround, and DFM feedback included.
Do you supply components for automated guided vehicles (AGVs) and mobile robots?
Yes. AGV and AMR (autonomous mobile robot) developers require machined aluminium chassis components, wheel hubs and drive assemblies, lidar and sensor mounting brackets, battery enclosures, and docking station hardware. The Australian logistics automation sector is growing rapidly, and we supply both startups developing new AGV platforms and established integrators requiring production batch components. No minimum order — prototype-to-production on demand.
How does Rapid Manufacturing support robotics companies with fast iteration cycles?
Robotics development involves rapid design iteration — components are often redesigned multiple times before reaching the optimal configuration. Rapid Manufacturing supports this by providing 2-business-day quotes with free DFM analysis, express manufacturing (3–5 business days) for urgent prototype iterations, no minimum order quantity, and consistent quality across multiple design revisions. Many robotics customers maintain an ongoing supply relationship with us, progressing from early prototypes through to production batch orders as their platform matures.
What surface finishes are used for robotics machined parts?
Common surface finishes for robotics components include: hard anodising (Type III) for aluminium wear surfaces, bearing bores, and surfaces subject to contact loading; standard anodising (Type II) for corrosion protection and cosmetic finish on external structural components; black anodise for clean appearance and reduced reflectivity in vision-guided robot systems; as-machined (no treatment) for internal structural components and prototypes; and electroless nickel for components requiring combined corrosion protection and wear resistance.
