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.

Polaris 8126 representative application case — Polaris 8126

Medium-Size Motor Housing Inspection

TRAVEL: 800 × 1200 × 600 mm
STRUCTURE: Production bridge CMM
PART: Motor / gearbox housing
ACCURACY: MPEe 2.5 + L/300 µm

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.

Reusable For

EV motor housings, gearbox housings, pump bodies, aluminum castings, fixtures and batch inspection work.
