Chotest SJ5200 universal testing machine for all thread gauges

Chotest SJ5200 universal testing machine for all thread gauges  

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, buttress thread, sawtooth thread and other large-slope thread, as well as ordinary 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 standards. With comprehensive and professional thread standards in database, it meets requirements of most customers.

5. Automatically generate test results according to relevant regulations and standards.

6. After one time 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 workholder are identified automatically, which avoids collision of measuring probe caused by operating errors. 

SJ5200 achieves full-automated and precision measurement of comprehensive thread parameters by using Heidenhain precision linear encoder system, precision air bearing drive system, imported 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 Heidenhain 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.

SJ5200 is a full-automated measuring machine. The operator only needs to install the thread, select matching standard and input relevant sizes & measuring range & other parameters in software, then the system measures automatically after click the "start" button. The software displays real-time tooth profile curve of thread 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 built-in thread standards, and test result is generated automatically. The whole process is completed in 2 min.

1. Full-automated measurement: Without human intervention, the machine implements measurement and evaluation of all thread parameters in 2 min, finally displays the measuring values. According to built-in thread standards, the system generates the test report automatically. 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: With quick workholders for thread and user-friendly software UI, without complex adjustment process and manual recording, 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): In the innovative structure for installation of measuring pin, the pin holder is fixed vertically(the pin holder aligns cross section of thread). This structure eliminates errors caused by repeated installation, which results in excellent repeatability.

6.Combined workholder(Patent No.3): Decrease the frequently-used workholders from 4 to 2 by applying Two-in-one and three-in-one ones without gasket and heel block.  These workholders can be used for measuring both thread ring and plug gauges. By reducing frequency of installation&uninstallation&calibration of different workholders, the work is more simple and efficient, in addition risk of operating errors is down much.

7. Ingenious balancing mechanism(Patent No.4): The problem of Z-axis swing while X-axis movement is solved completely by using ingenious balancing mechanism, which ensures the stability of the coordinate system in measurements, in addition measuring accuracy is improved .

8. Accurate & sensitive measuring force system 

Automatic control by computer in both directions. Measuring force range: 0.01 ~ 0.07N, that is far less than 0.14N of the similar machines. The micro measuring force protects measuring pin from abrasion so life of measuring probe is infinite, in addition workpieces are protected as well. The micro measuring force greatly helps to achieve measurements for large-slope threads as well as precision measurements for the ordinary threads.
