ROBOTICS MANUFACTURING

Precision CNC Components for Robotics & Automation

Robotic systems depend on accurate alignment, repeatable motion and components that fit together without unnecessary play or interference. Karry Precision manufactures custom CNC parts from customer drawings for robot joints, drive assemblies, end-effectors, housings, brackets and other precision mechanical structures.

  • Prototype, low-volume and repeat production support
  • 3-axis, 4-axis and simultaneous 5-axis CNC machining
  • Metals and engineering plastics for motion and structural parts
  • Inspection planned around functional and mating features
5-axis CNC machining for complex robotics components

What Matters in Robotic Mechanical Components

The best machining strategy starts with the interfaces that influence motion, alignment, weight and service life.

01 · MOTION ACCURACY

Motion Alignment

Critical bores, shafts, bearing seats and mounting datums should stay in controlled relationship to support smooth and repeatable movement.

02 · LIGHTER AXES

Low Moving Mass

Material choice and pocketed geometries can reduce moving weight while maintaining the stiffness required by robotic structures.

03 · BUILD CONSISTENCY

Repeatable Assembly

Locating faces, hole patterns and mating interfaces should support consistent assembly across prototypes and repeat production builds.

04 · LONGER SERVICE LIFE

Wear & Service Life

Fit, material and surface condition should be considered together for joints, guides, bushings and transmission components.

Manufacturing Capabilities for Robotics Projects

Select the machining route around geometry, functional features, production volume and inspection requirements rather than forcing every component into one process.

ENGINEERING FOCUS

Control the Interfaces That Affect Robotic Motion

A robotics component can meet its overall dimensions and still create assembly or motion problems if the critical relationships are not controlled. Drawing review should identify the features that influence positioning, bearing fit, drive alignment and tool mounting.

  • Bearing and shaft interfaces: bore size, coaxiality, roundness and surface condition
  • Motor and gearbox mounting: datum control, hole position and face perpendicularity
  • End-effector interfaces: repeatable hole patterns, locating features and mounting faces
  • Lightweight structures: pocketing, thin walls and stiffness balanced against distortion risk

Materials for Robotics CNC Machining

Material selection should reflect stiffness, weight, wear, friction, corrosion resistance, operating temperature and the required manufacturing process.

TOLERANCE & QUALITY CONTROL

Inspection Planned Around Fit, Position & Repeatability

Robotics drawings often contain a mix of general dimensions and a smaller number of function-critical features. Karry Precision evaluates tolerance requirements according to geometry, material, process and inspection conditions rather than applying unnecessarily tight tolerances to every dimension.

  • Typical CNC machining reference: around ±0.05 mm
  • Selected precision features can be reviewed for tighter control
  • CMM and other precision measurement methods for complex feature relationships
  • ISO 9001-certified quality processes and pre-shipment inspection
