Product catalog summary

GEMINI: Performance Specifications
The GEMINI 3D CNC Coordinate Measuring Machine offers various models with measuring strokes ranging from 1000 mm to 2000 mm in the X-axis, 800 mm to 1500 mm in the Y-axis, and 600 mm to 1000 mm in the Z-axis. The specifications adhere to ISO 10360-2:2009 standards, with maximum permissible errors (MPE) and limits (MPL) defined for volumetric length measuring errors and repeatability range. The probe configurations include MIH-TP6 and PH10T/M/PH20-TP20, both with a stylus length of 10 mm and a tip diameter of 4 mm. The machine operates optimally within an ambient temperature range of 18 °C to 22 °C.

Technical Characteristics
The GEMINI machine features a high-precision architecture with a fixed portal and moving table. It includes a sliding worktable with granite prismatic section sliding guides for the X-axis and a double granite crossbar for stability. The vertical axis is made of carbon fiber for enhanced dynamics and stability. The measuring system uses optical steel photoelectric scales and electronic scanning heads, offering a resolution of 0.1 μm. The drive system employs zero hysteresis friction drives with DC servo motors.

Stroke, Dimensions, and Weight
The machine's overall dimensions vary by model, with lengths ranging from 2890 mm to 4890 mm, widths from 1790 mm to 2490 mm, and heights from 2995 mm to 3845 mm. The maximum part weight capacity ranges from 750 kg to 2700 kg, while the CMM weight ranges from 5130 kg to 12910 kg.

Power and Pneumatic Supply
The power supply requirements are 1/N/PE 115/230 V~ ± 10 %; 50 / 60 Hz (± 4 %), with a maximum power of approximately 2.5 kVA and power consumption of 0.6 kVA. The air supply pressure ranges from 0.8 to 1.0 MPa, with an operative pressure of 0.6 MPa and air consumption between 160 - 225 Nl/min. The air quality must meet Class [1:4:1] according to ISO 8573:2010.

Environmental Conditions
The machine operates within a relative humidity range of 40% to 70% (non-condensing) and an operating temperature range of 15 °C to 35 °C. It is designed to withstand environmental vibrations with specific limits across different frequency ranges.
