ART CNC Machining LLC — Chicagoland’s go-to CNC shop for robotics and automation. From cobot joint housings and harmonic drive components to actuator shafts and end effectors, we machine the parts that make robots move. 5-axis capability. 30+ years experience. Fast turnaround. Bridgeview IL.
Robotics Capability
The robotics industry demands tolerances that leave no margin for error. At ART CNC, we've been machining high-precision components for automation OEMs, integrators, and research labs for decades. When your robot needs a part that fits, every time, this is where you come.
Structural housings and enclosures for articulated robot arms. Complex geometries, tight bore tolerances, lightweight aluminum and titanium options.
Wave generators, flex splines, and circular splines for harmonic reduction gearboxes. Ultra-tight tolerances critical for zero-backlash performance.
Precision-ground actuator shafts, lead screws, and spindle assemblies. Ground to ±0.0001" with superfinished surfaces for smooth motion.
Collaborative robot joint housings, torque sensor flanges, and interface plates. Designed to your CAD, machined to production tolerances.
Precision servo motor casings, encoder mounts, and brake housings. Multi-feature setups completed in a single 5-axis setup for maximum accuracy.
Custom end effector bodies, gripper jaws, and tool changers. Machined from aluminum, stainless, or engineering plastics to your exact specifications.
Parts We Machine

Why ART CNC
Robotics OEMs and integrators come to ART CNC because we understand that a robot is only as good as the precision of its individual components. Tolerance stack-up in a 6-DOF arm is unforgiving — even a few tenths of error in one joint housing multiplies across the kinematic chain.
We bring 30+ years of high-precision machining experience to every robotics job. Our 5-axis CNC machines complete complex joint components in a single setup, eliminating the re-fixture error that plagues multi-step machining processes.
From prototype to production, from a single harmonic drive flex spline to a batch of 200 actuator shafts, we deliver on-time with full CMM inspection documentation.
Explore Our 5-Axis Capability →Complex robot housings and joint components machined complete in one setup. No re-fixture, no accumulated error — just precision.
Full Coordinate Measuring Machine inspection with documented reports. You get data, not just parts. Critical for ISO-certified robot assembly.
One part to prove the concept, then 50, then 500. Same setup, same tolerances, consistent quality at every quantity.
Robot down? Cobot joint cracked? We understand production schedules. Rush jobs are our specialty when the line can't wait.
Send us your CAD files, drawings, or part specs. Our engineers respond fast — usually same day.
