Built for the Labs Spinning Out of Kendall Square
Boston's robotics scene runs deep. From MIT's Computer Science and Artificial Intelligence Laboratory on Vassar Street to the hardware startups scaling up in Somerville's Assembly Row, your teams need machined parts that perform through thousands of cycles — not just a prototype run.
RivCut machines robot arm links, end effectors, actuator housings, and custom drivetrain components to tolerances as tight as ±0.0005 inches. No minimums. No long lead times. Upload your CAD file and get a real quote today.

Precision CNC Machining for Robotics Teams
Robotics and automation companies in Boston need parts that are light, stiff, and precisely made. A robot arm link that's off by 0.003 inches affects positioning accuracy across thousands of cycles. We machine aluminum, steel, and titanium to tolerances as tight as ±0.0005 inches — and keep programs on file for fast re-orders.
Lightweight Materials
We machine aluminum 7075 and 6061, titanium, and stainless — materials that give your robot the strength-to-weight ratio it needs.
Tight Tolerances
We hold ±0.001" on general features and ±0.0005" on critical bores and mating interfaces. CMM verified on every complex order.
Fast Re-Order Ready
We keep your programs and fixtures on file. When you need more parts, re-orders are fast with no re-programming delays.
What We Machine for Boston Robotics Teams
Boston robotics programs demand precision, traceability, and speed. We deliver all three with every order.
Actuator Housings
We machine arm links, shoulder brackets, and wrist housings from aluminum 7075-T6 and 6061-T6. These alloys keep your robot's inertia low without sacrificing stiffness. We hold ±0.001 inches on general features and ±0.0005 inches on critical bores and mating interfaces — CMM verified on every complex order.
±0.0005" boresJoint & Linkage Components
End effectors fail at the fingers. We machine titanium and stainless steel gripper jaws and tool flanges with tight flatness callouts. Your gripper needs to close the same way on cycle 1 and cycle 100,000. We make that happen.
Pin-fit precisionSensor Mounting Hardware
Harmonic drive housings, servo motor mounts, and gearbox adapters all need precise bore alignment. We 5-axis mill complex housings in a single setup to avoid stack-up error from repositioning.
Alignment-criticalEnd Effector & Gripper Parts
Boston robotics teams often build custom test rigs and calibration fixtures in-house. We machine aluminum tooling plates and fixture blocks to support your validation work before you go to production.

Why Boston Robotics Teams Use RivCut
You are in Boston. We are in Union City, California — right next to the Port of Oakland. That matters. Parts ship via FedEx Priority or UPS Air and land at Logan International Airport or your Seaport District office in two to three business days. No cross-country freight broker. No mystery tracking numbers.
Fast Design Iterations
Boston engineers start work at 9 AM Eastern. That's 6 AM our time. Our floor is already running. When you upload a file in the morning and need a DFM review before your afternoon standup, we can make that happen. West Coast manufacturing hours align well with East Coast engineering schedules.
Programs Saved for Re-Orders
Boston's robotics ecosystem moves fast. Kendall Square spinouts go from bench prototype to Series A in under two years. You do not have time to wait six weeks for a machine shop to open a new account. RivCut gives instant AI pricing on uploaded CAD files. You get a number in minutes, not days.
CMM Inspection Included
We also understand the supply chain pressure Boston teams face. MIT spinouts and iRobot-adjacent suppliers in the Route 128 corridor are often buying from the same small pool of New England machine shops. Lead times get long fast. Sourcing from RivCut gives you a reliable second source with no minimum order quantities — useful when your primary shop is backed up before a product launch.
No Minimums
Order 1 part or 500. We run robotics from single prototypes to small production runs without artificial minimums or setup fees.
