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 twodimensional
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-automatic measurement for comprehensive parameters of cylindrical thread plug gauges, cylindrical thread ring gauges,
taper thread plug gauges, taper thread ring gauges, plain ring gauges, plain plug gauges and other gauges with internal &
external dimensions, including virtual pitch diameter , single pitch diameter, basic pitch diameter, major diameter, minor diameter, thread pitch, thread angle, half of thread angle, flank straightness, lead angle, taper, etc.
2. Can measure trapezoidal thread gauges, buttress thread gauges, sawtooth thread gauges and other large-slope thread
3. Can measure comprehensive parameters of single thread and multiple thread.
4. Measure various thread gauges according to GB, ISO, BS, ANSI, DIN, JIS, API standards. With comprehensive and
professional thread standards in database, it meets requirements of most customers.
5. Automatically generate test report according to selected standard.
6. After once measurement, the software can records various parameters of thread and display data of any position, in addition
it generates the thread curve, relevant parameters and analysis chart automatically.
7. Measuring probe and work holder are identified automatically, which avoids collision of measuring probe caused by misoperation
8. One-sided or two-sided measurement and analysis for gauges.
9. Controller for measuring pin positioning: with an easy-touse buttons control box, the operation is more flexible.
10. User-friendly English software system and simple & convenient operation.
11. Test results are saved automatically with name of measuring series number + size of measuring gauge + type
of measuring gauge, which can be recognized easily. With centralized database management for measuring records,
the user can query and manage the measuring records according to object type, testing institution, manufacturing
number, inspector, submitted institution, equipment number, inspection date, effective date, etc.
12. Can print multiple selected test records or test certificates from database at once time.
13. Can export test data to Word, Excel, AutoCAD (optional) files.
14. Data backup and restore.
15. Output reports in a variety of formats in Word or PDF, particularly the format can be customized.
16. Support user-defined standards.
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
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-inone 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 abrasionfree,
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.
