Precision CNC Machining for Cobot Teams

Collaborative robots share workspace with humans, so every component must be lightweight, smooth, and dimensionally exact. A safety cover with a sharp edge or a misaligned gripper plate can compromise both performance and safety. We machine aluminum 6061-T6, 7075-T6, and Delrin to tolerances as tight as ±0.0005 inches. Smooth radii, deburr-free edges, and consistent surface finishes on every part.

1

Lightweight Materials

Aluminum 6061-T6 and 7075-T6 for structural arm segments. Delrin and PEEK for low-friction bushings and wear components. Every gram saved increases your cobot's payload capacity.

2

Human-Safe Surfaces

Smooth radii, filleted edges, and deburr-free surfaces on every part. Cobots operate alongside people — we machine your safety-critical surfaces to meet ISO/TS 15066 design intent.

3

Fast Iteration Cycles

Cobot startups move fast. We turn around prototype revisions in 5 to 7 days and scale to production when your design is locked.

Serving the Collaborative Robotics Industry

The cobot market is the fastest-growing segment of industrial robotics. Cobots work alongside humans in manufacturing, logistics, and laboratory settings — and their mechanical components must reflect that close proximity.

Every arm segment, joint cover, and gripper plate must be lightweight, smooth, and precisely machined. The difference between a good cobot and a great one often comes down to mechanical precision.

We machine components for cobot startups and established manufacturers alike. Upload your STEP file for instant AI pricing.

Universal Robots — Cobot Pioneer

The company that defined the collaborative robot category. UR cobots are used in thousands of factories worldwide, driving demand for precision arm segments and joint components.

FANUC CRX Series — Safety-Rated Cobots

FANUC's CRX collaborative robots combine industrial reliability with human-safe design. Precision-machined lightweight components are essential for their smooth, rounded arm geometry.

ABB GoFa & SWIFTI — Next-Gen Cobots

ABB's latest cobots push the boundaries of speed and payload while maintaining safe human interaction. Lightweight, precision-machined arm segments are critical to their performance.

Doosan Robotics — Collaborative Automation

Doosan's cobot lineup serves manufacturing, food service, and logistics. Their torque-sensing joints rely on precision-machined housings and sensor mounts.

Built for Cobot Teams

Cobots need lightweight parts with smooth surfaces and tight tolerances.

Lightweight Design Expertise

We machine complex pocket patterns and thin-wall features in aluminum to minimize arm weight. Every gram saved means more payload for your cobot.

Human-Safe Surfaces

Smooth radii, deburr-free edges, and consistent surface finishes on every component. We understand ISO/TS 15066 design intent and machine accordingly.

Tight Bore Tolerances

±0.0005" on bearing bores and sensor mounting pockets. CMM inspection on every order verifies concentricity and true position for accurate joint performance.

Rapid Prototype Iteration

Cobot startups iterate fast. We deliver prototype revisions in 5 to 7 days and scale to production quantities when your design is locked and validated.

Questions from Cobot Teams

Aluminum 6061-T6 and 7075-T6 are the most common choices. 6061 offers good machinability and cost efficiency for lighter-load cobots. 7075 provides higher strength-to-weight for arms that need maximum stiffness with minimum mass.
Yes. Cobots require rounded, pinch-free surfaces for safe human interaction. We machine smooth radii and fillet transitions on safety covers and joint housings using ball-end mills and 5-axis contouring.
We hold ±0.001 inches on bolt patterns and dowel pin holes, and flatness within 0.001 inches. This ensures repeatable gripper mounting and accurate TCP (tool center point) calibration.
Yes. We machine sensor housings from aluminum 6061 and 7075 with tight bore tolerances for force-torque sensor integration. Precise mounting surfaces ensure accurate force feedback data.
Yes. We use 3-axis and 5-axis CNC milling to create complex internal pocket patterns that reduce weight while maintaining structural rigidity. Critical for cobot arms where payload depends on arm weight.
We offer Type II and Type III anodize, bead blast, powder coat, as-machined, and passivation for stainless. Many cobot makers choose bead blast plus Type II anodize for a clean, professional appearance.
Most cobot prototype parts ship in 5 to 7 business days. Rush orders on simpler geometries can ship in 3 to 4 days. Upload your STEP file and tell us your deadline.
