JD21Projection Length Measuring Machine
PURPOSE
The Projection length measuring machine is a high precision optical instrument for measuring length.It can be used to determine the size of workpiece by means of direct and differential measurements.The chief uses of the machine are as follows:
.Differential measurements of the gauge block of 4th and 5th grade over 100 mm;
.Direct measurements of the calibration rods of the micrometer calipers, inside calipers micrometer and self-made measuring rods;Internal measurements of calipers gauge and bore diameter;Measurement of external thread pitch diameter.It can be used in inspection department of various factories and mines, scientific research institutes and the state metrological organizations.
The base of the instrumen
Ts, which is made of high quality cast iron, has enough strength and stability
Using measuring theory, real-time correct Abbe error.
Adopting a novel wax screen with magnifier as the projection reading screen, imaging clearly
The instrument has complete measuring accessories, it is easy to operate and its application is extensive
