Precision CNC Machining for Robotics Teams
Robotics and automation companies in Union City 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.
Parts for Union City Robotics Companies
Robot arm links, end effectors, actuator housings, and more.
Robot Arm Links & Joints
Structural arm links, elbow joints, shoulder housings, and wrist assemblies machined from aluminum 7075 and titanium. Low weight, high stiffness, and precision bores for bearing and motor fits.
7075-T6 & TiEnd Effectors & Grippers
Custom gripper jaws, suction cup mounts, magnetic pick tools, and end-effector flanges. Machined to tight tolerances so your robot grips reliably every cycle. Hard anodize for wear resistance.
Hard anodize avail.Actuator & Motor Housings
Motor mounting flanges, gearbox bodies, linear actuator housings, and servo brackets. Tight bore tolerances for shaft and bearing fits. Aluminum and steel for strength and weight balance.
±0.001" boresLinear Rail & Base Plates
Machine base plates, gantry frames, rail mounting plates, and leveling pads. Precision-machined flat surfaces, precise rail mounting slots, and tapped holes in exact patterns.
Flatness ±0.001"Force/Torque Sensor Mounts
Custom mounting adapters for ATI, Robotiq, and other F/T sensors. Precise interface geometry so your sensor reads accurately. Stainless and aluminum.
Stainless & AlCustom Automation Brackets
Camera mounts, sensor brackets, cable management fixtures, and integration hardware. Aluminum 6061, quick turnaround, and no minimum order. Great for automation R&D.
