CHOTEST: Shaping the Future of Smart CMM Technology

The 3D Coordinate Measuring Machine “EARTH” sets a new benchmark in dimensional metrology — combining precision engineering, patented innovations, and AI-powered intelligence to deliver an unmatched measurement experience.

Designed, developed, and built by our top engineers, EARTH is not just another CMM — it’s the first truly Smart CMM, created to think, adapt, and evolve with the needs of Smart Factory standards.

With integrated artificial intelligence, advanced automation, and future-ready connectivity, the CMM "EARTH" ensures faster inspection cycles, predictive accuracy, and seamless integration into smart manufacturing environments.

This is more than an evolution… it’s a revolution in Metrology.

A new standard is born — and it begins here.

Specifications

Indexable Probe Head

ACH100S / ACH100S-5

• Probe head achieves A-axis range: 0-105° (or 0-115°), B-axis range: -180°~+180°.
• Probe head uses precision multi-point positioning to achieve high positioning accuracy.
• Key components use composite materials and high-strength materials.
