Use of the instrument
The digital measuring projector is a precise and high-efficiency measuring instrument integrating light, machine and electricity. It is divided into two types: reverse image and positive image. Department. This instrument can efficiently detect the contour size and surface shape of various complex workpieces, such as templates, stamping parts, cam threads, gears, forming milling cutters, etc.
the characteristics of the instrument
The optical system of the instrument is of good quality, the objective lens has clear imaging, and the magnification is accurate. Under transmitted light illumination, the profile measurement error is less than 0.08%; the measurement indication error can reach (3+L/75) μm, L is the measured length (unit : mm)
