Small tool microscope

Instrument usage
Small toolsmicroscopeJGX-1 is one of the precision optical measuring instruments with versatility. Wide measurement range. Accurate and reliable, easy to operate. Therefore, it is particularly suitable for precision machinery manufacturing and tool manufacturing industries. The main scope of use is as follows:
(1) Measure the shape template, template knife, etc. according to the Cartesian coordinates;
(2) Measuring threads; Measurement of pitch, outer diameter, and inner diameter of threads, determination of pitch, helix angle, helix angle on the profile position of the threaded shaft and thread shape (roundness, flatness, straightness, etc. of the tooth surface)
(3) Measuring angles: measuring the helix angle of thread comb cutting tools, thread milling cutters, profile angles of various template milling cutters, and angles of various shape templates.
(4) This instrument can also be used as an observation microscope, such as for surface smoothness testing and other similar tasks.
(5) This instrument can be equipped with special equipment and accessories, and can change different magnification factors. It is extremely convenient for measuring complex or small shaped workpieces
