Features:  
This instrument, adopted advanced means and methods of dynamic characteristic analysis, full-space error software compensation, etc. and with sound rigidity and stability, belongs to large-sized high-performance digital-controlled volumetric measuring machine; which would be suitable for conducting accuracy survey of the sizes and shape and location allowance tolerance for various large- and middle-sized machinery parts and accessories on large-sized product production spots or in the measuring centers; thus completing tasks of parts detection, overall size measuring, reverse engineering, process control, etc.

Usages:  
Adopting the design of L-type viaduct bridge structure, at the same time of assuring the open space to guarantee the stability and fine driving function of the measuring instrument, it can minimize its angle swinging and perpendicularity deformation under operation, thus ensuring the high-precision of the measuring instrument.
The channel-section design is adopted for the main guideway and the layout of closed static pressure guideway for the spatial bearings can enlarge the gas film rigidity and upgrade the precision of X-direction aero-floating guideway.
Fine-quality granites are selected for worktable, 3-axial guideways and vertical shafts, thus the complete instrument is of fine stability, with good temperature stability and sound hardness.
This instrument can be installed with trigger- and contact- series scanning measuring heads, LS-series laser line scanning measuring heads, high-precision laser spot scanning measuring heads by the RENISHAW Co.; thus realizing complicated measuring tasks of high-speed non-plane scanning (reverse engineering), etc.
