Zeiss CONTURA G2 (CMM)

Main Features

High-precision coordinate measuring machine (CMM) used in manufacturing and quality control for precise 3D measurements.

· RDS Articulating Probe Head: Allows the probe to rotate in small increments (e.g., 2.5° steps) to hundreds of positions, enabling measurement of complex part features that are difficult to access without re-clamping.

· VAST XXT Scanning Probe: High-precision scanning probe capable of both single-point measurement and continuous surface scanning, suitable for geometry, shape, curve, and contour inspection.

· CALYPSO Software: ZEISS software package for creating measurement programs, executing inspections, comparing results with CAD data, and analyzing deviations.

· Air Bearings and Ceramic Guideways: Ensure smooth and highly precise movement of each axis, while improving thermal stability and reducing vibration effects.

Specifications

· Measuring Range (X/Y/Z): Approximately 700 × 700 × 600 mm (commonly referred to in the industry as “7/7/6”; equivalent to 27.6″ × 27.6″ × 23.6″).

· Probe & Rotary Table: RDS-D-CAA motorized articulating probe head, 2.5° indexing with 20,736 angular positions; supports VAST XXT scanning probe and XDT multi-point touch-trigger probe, with a maximum scanning speed of approximately 500 points/second.

· Length Measurement Uncertainty (MPE, RDS + VAST XXT, 7/7/6): Under conditions of 18–22 °C, E0 ≈ 1.7 + L/350 µm; extended term E40 ≈ 1.7 + L/250 µm (L in mm).

· Typical Scanning / Form Measurement Indicators (RDS + VAST XXT, 7/7/6):

· Scanning error THP ≈ 2.7 µm (ISO 10360-4).

· Roundness error RONt ≈ 1.7 µm (ISO 12181).

· Single-stylus form probing error PFTU ≈ 1.7 µm (ISO 10360-5).

· Maximum Workpiece Weight (series reference): Approximately 730–1200 kg (depending on model size).

· Software: ZEISS CALYPSO (commonly supplied as standard configuration).

Applications

· Dimensional inspection and quality control in manufacturing, ensuring parts meet design specifications.

· Measuring complex geometries (e.g., small radii, curved surfaces, free-form shapes, deep-hole features) without repeated re-clamping.

· Widely used in industries requiring strict tolerance control such as precision manufacturing, mold making, aerospace, and automotive components.
