Case Overview
Ethan Keller, an engineering manager at an automation equipment manufacturer, partnered with HUB to manufacture precision CNC components for a 6-axis robotic pick-and-place system. The project included servo motor mounting plates, bearing housings, precision shafts, structural brackets, and end-effector adapters, all requiring exceptional dimensional accuracy and repeatability.
Designed for high-speed, continuous operation, the robotic system demanded tight positional tolerances, precise bearing alignment, and superior surface finishes to minimize vibration and ensure smooth, reliable motion. Consistent machining quality across production batches also helped streamline assembly, reduce calibration time, and maintain long-term system performance.
Project Requirements
The robotic system required precision-machined components capable of supporting accurate positioning, smooth motion, and reliable long-term operation. Key requirements included:
- Tight positional and dimensional tolerances
- Accurate bearing alignment and mating interfaces
- Lightweight yet rigid structural components
- Consistent repeatability across production batches
- High-quality surface finishes for precision assemblies
Manufacturing Challenges
Producing components for robotic motion systems required more than achieving tight tolerances. Several critical machining challenges had to be addressed to ensure reliable assembly and long-term performance:
- Maintaining positional accuracy across multiple mating components
- Machining bearing bores and locating features with precise alignment
- Controlling dimensional consistency across repeat production batches
- Achieving excellent surface finishes to reduce friction and vibration
- Ensuring interchangeable parts for efficient modular assembly
Manufacturing Solution
To address the machining and assembly challenges of the robotic motion system, HUB Machining implemented the following manufacturing strategies:
- 3-axis and 5-axis CNC machining to produce complex components with high positional accuracy and minimize setup-related errors.
- Precision CNC turning for shafts and bearing housings to ensure concentricity, precise bearing fits, and smooth rotational performance.
- Controlled machining of locating features and mounting interfaces to maintain accurate alignment across multiple mating components.
- Tight process control and repeatable machining methods to ensure dimensional consistency across prototype and production batches.
- Precision surface finishing and comprehensive dimensional inspection to verify critical features, reduce friction, and support reliable long-term operation.
Results & Value
The completed components met the demanding requirements of the robotic system and supported efficient equipment assembly and reliable operation.
- Consistent positioning accuracy across critical assemblies
- Reduced assembly adjustments and calibration time
- Reliable repeatability from prototype to production
- Smooth robotic motion with reduced vibration

What Is CNC Machining for Automation & Robotics?
Automation and robotics CNC machining is the process of manufacturing high-precision components used in industrial automation equipment, robotic systems, and motion control assemblies. CNC machining enables complex geometries, tight tolerances, and consistent dimensional accuracy, making it ideal for critical parts such as servo motor mounts, bearing housings, precision shafts, structural brackets, and end-effector adapters. From prototype development to full-scale production, CNC machining ensures reliable performance and repeatable quality.
Why Is Precision CNC Machining Essential for Automation Equipment?
Automation systems rely on precise mechanical components to achieve accurate positioning, smooth motion, and reliable assembly. Even small dimensional variations can affect bearing alignment, motion accuracy, and overall system performance. Precision CNC machining provides tight tolerances, excellent repeatability, and consistent quality, helping manufacturers reduce assembly adjustments, improve equipment reliability, and support long-term operation in demanding industrial environments.
What Makes Automation Components Different ?
Unlike standard mechanical parts, automation and robotics components require higher precision and reliability due to their complex assembly requirements and continuous operating conditions.
Key requirements include:
- Multiple precision mating features that must align accurately during assembly
- High repeatability to maintain consistent motion and system performance
- Accurate bearing fits and critical interfaces for smooth mechanical operation
- Excellent surface finishes to reduce friction and improve component lifespan
- Consistent dimensional stability across production batches
- Reliable performance under continuous dynamic loads
- Strict manufacturing and inspection standards to ensure assembly accuracy
These requirements make automation components more demanding to manufacture than conventional machined parts, requiring advanced CNC machining capabilities and rigorous quality control.

Feedback from Michael Carter
“Our previous supplier struggled to maintain dimensional consistency between batches, which caused alignment issues during equipment assembly. HUB Machining provided stable machining quality from prototype through production, and every shipment matched our inspection requirements. That consistency has helped reduce assembly time and improve overall production efficiency.”
