Product descriptions

SJ5200 achieves full-automated and precision measurement of comprehensive thread parameters by using precision linear encoder system, precision air bearing driving system, high-end servo motor control system, high performance industrial computer control system and large capacity memory technology. After driving the measuring probe to contact with workpiece by precision air bearing system, the software records the horizontal and vertical coordinates in measuring process by applying precision linear encoder system, then, on the basis of synthesizing the two-dimensional measuring values, the software calculates and obtains a variety of thread parameters according to relevant definitions from norms.

SJ5200 is a full-automated measuring machine. The operator only needs to install the thread gauge, select matching standard and input scanning length in software, then the system measures automatically after click the "start" button. The software displays real-time tooth profile curve of thread gauge, and calculate the major diameter, pitch diameter, minor diameter, thread pitch, thread angle, other thread parameters automatically. Finally the system qualifies a variety of thread parameters according to selected thread norm, and test report is generated automatically. The whole process is completed in 2 min.
