    Motion & Assembly-Oriented Design Review

    We review robotic arm segments, actuators, and end-effector components with a focus on stiffness, weight, and assembly alignment. Tolerances and interfaces are checked to support smooth motion.

    • Evaluate joint interfaces, bearing seats, and mounting patterns
    • Suggest design changes to reduce weight and simplify machining
  • Setup

    CNC Programming for Motion-Critical Parts

    CNC programs and fixtures are created to machine lightweight yet rigid parts. Setup aims for tight control of concentricity, parallelism, and alignment features.

    • Optimized toolpaths for weight-relief pockets and ribs
    • Fixtures that maintain geometric alignment during machining
  • Production

    Precision Machining for Robotic Assemblies

    We machine structural and motion-critical parts on multi-axis centers with strict control of tolerances. Runout, flatness, and bore alignment are monitored to support smooth robotic movement.

    • Multi-axis machining for housings, shafts, and grippers
    • In-process checks for concentricity and alignment surfaces
  • Finishing

    Surface Treatment for Wear & Appearance

    Components receive anodizing, hard-coat, or plating to resist wear and corrosion. Surface finishes are controlled to support smooth motion and a clean, professional appearance.

    • Hard-wearing finishes on sliding and rotating elements
    • Cosmetic finishing for visible robot surfaces
  • Delivery

    Kit Packing for Robotic Assemblies

    Parts are kitted and labeled by assembly group to simplify your build process. We coordinate deliveries to support prototype builds, pilot runs, and full-scale production.

    • Kits labeled by robot axis or assembly module
    • Protective packaging tailored to precision parts

Material

Materials & Surface Treatment

We machine a broad range of metals and engineering plastics and offer finishes tailored to robotics environments. Surface treatments improve wear resistance, corrosion protection, and electrical isolation where required.

  • Lightweight aluminum for structures; stainless steels and titanium for corrosion resistance; hardened steels for wear-critical components.
  • Finishes include anodizing, hard-coat, passivation, electroless nickel, plating, black oxide, electropolish, precision grinding, and laser etching for traceability.
