Quality features (no move of measuring workpiece, move the gantry tower)

Bring you into a 3D composite measurementworld: Automatic gantry big-stroke composite coordinate measuring instrument.

The base is made of marble (grade 00)material. With solid design of platform, it is highly stable and rigid.

Grinding level ball screw and preciselinear guide rail are used. Coordinated with Panasonic high performance ACservo system for

closed-loop control, it has high precision,high speed and high stability.

TEO HD color 800TV CCD of industrial levelfrom the United Statesis used to ensure high quality measurement screen and rapid measuring rate.

Automatic magnification change lens isused, calibration is not required after changing magnification. 

Programmable 4-ring-and-8-zone LED surfacecold light source, with cold light source of straight axle profile (coaxilecold light source is optional).

Open-type mounting optical ruler 0.0005mm.

Renishaw contact measuring head set from Britain (automatic probe SCR system is optional)and Keyence laser measuring head set from Japan.

Self-reliantly developed automatic 3Dmeasuring software with powerful function, enabling programmable automaticmeasurement.

Coaxial measurement of image, probe andlaser, enabling programmable automatic measurement.

Z-axle measuring range: 400 -500 mm.

Double Z-axles can be selected for measurement.
