Gemini High-Precision Bridge CMM

A higher-accuracy bridge CMM platform for tight-tolerance parts, scanning workflows, and demanding quality labs.

Hero Copy
Gemini is designed for metrology teams that need finer measurement performance from a bridge CMM format. With a rigid granite guideway structure, enclosed air-bearing design, and scanning-capable probing options, Gemini supports high-precision inspection for complex parts and short-cycle measurement routines.

Specifications, configurations, and performance values are for reference only and may vary by model, options, operating environment, and acceptance standard. Final specifications should be confirmed in the quotation or technical agreement.

Recommended Probing and Controller Packages

  • High-precision touch-trigger package: CZ10T-S motorized head with CF20 modules.

  • Scanning package: SC30 scanning probe with CZ10M-S head and MACC3000Plus controller.

  • Mixed inspection package: touch-trigger modules for discrete features plus scanning probe for profiles and freeform surfaces.

  • Final package selection should be based on part geometry, tolerance, cycle time, software, and acceptance requirements.

FAQ
Q: Does every Gemini model have 0.9+L/300 um accuracy?
A: No. The listed 0.9+L/300 um value applies to the Gemini565 example. Accuracy varies by model size and configuration.

Q: Is Gemini suitable for scanning?
A: Yes. Gemini is well suited for scanning workflows when paired with the appropriate probe, controller, and software configuration.

Q: What makes Gemini different from Polaris C?
A: Gemini is positioned for higher-precision bridge CMM applications, especially where tighter tolerances or scanning stability are required.

Q: Can Gemini be configured for both touch-trigger and scanning inspection?
A: Yes. Mixed probing configurations are available after technical review.
