TSM universal thread scanning measuring machine is suitable for cylindrical thread plug gauge, cylindrical thread ring gauge, taper thread plug gauge, taper thread ring gauge, smooth ring gauge, smooth plug gauge and so on. The role of various kinds of inside and outside micrometer in diameter, single pitch diameter and large diameter, path, pitch, tooth type half Angle, tooth profile deviation, outline the measurement of parameters such as Angle and taper, operation simple and convenient and quick, application range, high uncertainty of measurement, is the ideal of metrology lab for such parameters detection measurement instruments. Universal thread measuring machine for automatic measurement, two minutes to complete a shaft section of all the measured parameters of the scanning measurement, and display all the measurement results.
