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.

1. Full-automated measurement: Scan test objects and display all values in 2 minutes without manual intervention and calculation.According to selected thread standards, the system generates the test report finally. That significantly simplifies the operator's work, as well as improves the measuring efficiency, quality and accuracy.

2. Resolution is 0.01um; High accuracy, high stability and high repeatability.

3.Simple, humanized design: Thanks to quick workholders for thread, object installation is very simple and easy. Due to
user-friendly software interface, the operator can be trained to use it within a few minutes. Operation of the machine is
extremely simple.

4. 3D navigation function(Patent No.1): Greatly improve the operating convenience, accuracy, safety and reliability.

5. Convenient and accurate replacement of measuring pin(Patent No.2): Thanks to innovative structure for probe installation, the probe is fixed easily and simply. This structure eliminates errors caused by repeated installation, which guarantees excellent repeatability.

6.Combined workholder(Patent No.3): Thanks to two-in-one and three-in-one workholders, gaskets and heel blocks are not required.
These workholders can be used for measuring both thread ring and plug gauges, which makes work more simple and efficient, moreover reduces risk of misoperation.

7. Ingenious balancing mechanism(Patent No.4): Thanks to ingenious balancing mechanism, the problem of Z-axis swing while X-axis movement is solved completely, which ensures the stability of the coordinate system during scanning, consequently measuring accuracy is improved.

8. Accurate & sensitive measuring force system
Measuring force automatically varies from 0.01 ~ 0.10N according to different gradient during scanning. Thanks to micro measuring force, measuring pin is almost abrasion-free, so lifespan of probe is very long, in addition test objects are protected as well.
The micro measuring force also greatly helps to achieve measurements for steep-slope thread gauges.

Note:
* Optimum ambient temperature is 20 ℃.
