Precision CNC Machining for Robotics Teams
Robotics companies need parts that are lightweight, precise, and ready fast. We machine aluminum, steel, titanium, and PEEK for lightweight strength — from single prototypes to production volumes. Every part ships with CMM inspection and full material documentation.
Lightweight Materials
We machine aluminum 6061-T6, 7075-T6, titanium 6Al-4V, and PEEK — optimized for the strength-to-weight ratios robotics demands.
Tight Tolerances
We hold ±0.001" on general features and ±0.0005" on bearing bores, mating surfaces, and precision fits. Every part is CMM verified.
Rapid Iteration
Upload a new revision, get instant pricing, and we machine the updated part. No setup fees for design changes — built for R&D velocity.
Built for Robotics Teams
Your robot moves fast. Your machine shop should too.
Custom Fixturing Expertise
Complex robotics geometries need custom work-holding. We design and build fixtures in-house so your parts come out right the first time — no compromises on accuracy.
CMM Inspection
Every critical dimension is verified before shipping. Your receiving team gets a documented inspection report — no guessing, no shortcuts.
Prototype to Production
From single prototypes to 5,000+ unit production runs. As your robot moves from R&D to manufacturing, we scale with you — same quality, better unit pricing.
Fast Response
Upload your file and get a response fast. Robotics prototypes in 3–7 days. We communicate directly — no layers of sales reps between you and the shop floor.
Parts for Robotics & Automation Companies
Robot arm joints, actuator housings, end effectors, and more — precision machined and fully documented.
Robot Arm Joints & Links
Shoulder, elbow, and wrist joints machined from aluminum and titanium. Precision bores for bearings, dowel pin holes for alignment, and lightweight pocket features to reduce inertia.
±0.001" standardActuator & Motor Housings

Real Robotics Parts. Real Results.
See how we solve machining challenges for robotics and automation teams.
Robot Arm Joint — Titanium 6Al-4V
Coaxial bores held to 0.0003" concentricity for harmonic drive integration. Coolant temperature controlled to ±2°F. Zero shimming required at assembly.
Actuator Gearbox Housing — Prototype to 500 Units
Bridge production from 10 prototypes to 500 units. Cycle time reduced 38%. SPC monitoring held Cpk > 1.67 on bearing bores. Zero rejects.
End Effector Gripper Jaw — 4140 Steel
Hardened to 45-50 HRC. Matched pairs from same heat treat batch. 2.3M cycles achieved (spec: 1M). Zero grip failures in pilot.
Quick-Change Sensor Bracket — 6061-T6
Kinematic mounting for LiDAR/camera on AMR. DFM flagged resonance risk — wall thickness fix pushed frequency to 230 Hz. SLAM accuracy up 15%.
Linear Actuator Body — 303 Stainless
Ball screw bore straightness 0.0003" over 200mm. Rail parallelism 0.0005". Stage positioning ±1 μm — achieved without grinding.
Mobile Robot Chassis Plate — 7075-T6
18" × 12" pocketed plate, 40% weight reduction. Alternating-side roughing for flatness. 8+ hour battery life (spec: 6 hours).
