Best-Fit Applications
Where Polaris Fits Best
Polaris is the general manufacturing bridge CMM choice when part sizes, load requirements, and inspection variety exceed entry-level systems but do not require Gemini or Libra.
CNC machined parts
Use Polaris for general manufacturing QC across machine shops, fixtures, castings, and automotive components.
Automotive Powertrain components
A broad bridge CMM platform when part sizes vary and the project needs value-focused scanning or touch-trigger options.
Fixtures and tooling
Best when a controlled quality room is available and the tolerance target does not require Gemini or Libra.

1Customer Scenario
Production machining inspection for aluminum housings with bearing bores, sealing faces, bolt-hole patterns and side features.
2Why This Machine
More measuring capacity than a compact CMM while still fitting into a standard quality room for daily production QC.
3System Configuration
Bridge CMM with motorized probe head, touch-trigger probe and optional scanning package for profile or sealing surfaces.
4Measurement Problem Solved
Verification of bore location, true position, flatness, parallelism, perpendicularity and relationships between machined datums.
Similar applications
EV motor housings, gearbox housings, pump bodies, aluminum castings, fixtures and batch inspection work.
