Product Description
It adopts the design for optical path of single mirror. Therefore, the loss for
Energy transfer is small and illumination of projection is more even.
The coating technology for sepcial mirror has good anti-dust effects and is easily to clean.
The worktable has large moving range and srtong load capacity, which is suitable for measure large parts.
It can conveniently measure the parts with helix angle because the worktable can swing the angle of ± 15° .
It can conveniently change the objective and the location is accurate because of the turret for high precision objective.
Adoptsimported transucer grating (Renishaw or Heidhain) and the data processing system, so the efficiency is hight and error is small.
The rich auxiliary measuring accessories of square worktable and circulare worktable is better measurements of different parts.

The instrument is convenient for measuring efficiently different shapes of workpieces with complicated profiles and surfaces, such as formed milling cutter, gear, thread cutter, cam, template, punched pieces, and various cutters and tools. Especially, it is suitable for measuring workpieces with large dimensions. Therefore, this instrument is widely used in steam turbine factories, aeroplane engine factories, mafacturing factories for tool and mold and various realtive machine building industries.
