Main purpose
JGX-2 Large ToolmicroscopeIt is a fundamental precision optical measuring instrument Large toolsmicroscopeA multifunctional measuring instrument widely used by metrology departments in machine manufacturing factories, scientific research institutions, and universities. The following measurements can be made:
1. Verify the shape of the sample, sample cutter, sample milling cutter, die, and cam.
2. Measure the pitch, outer diameter, inner diameter, pitch, helix angle, and helix angle of the thread axis to determine the profile position and thread shape (such as tooth roundness, flatness, flatness, etc.).
3. Measure the helix angle of thread cutting tools, thread comb cutting tools, thread milling cutters, various template milling cutters, and template profile angles of various shapes.
4. Measure the width of the inner hole and various grooves using an optical locator.
5. Measure the center distance between two holes and the distance between slits, line segments, or symmetrical shapes on the part using a binocular eyepiece.
6. By using a circular arc contour eyepiece, it is convenient and accurate to measure the circular arc dimensions of R0.1~R100.
