Detailed steps of the metal tensile test steps: Precision turned parts are mainly in six axle lathe with sticks of metal materials finished, such as variety of high precision and quality of electronic, computer precise components, communication components, automotive parts and accessories, machinery parts, sanitation hardware parts, optics precise parts, medical appliances, pneumatic tools accessories. We are very strict with our precision turned parts through the finished production is continuously improvement and growth, we will give you the best quality and services about our precision turned parts.

Open the power switch of the test machine main unit and preheat it for more than 15 minutes.
Start the computer, open our test software, and connect to the host;
Select the test plan, and hang the name of the test plan that needs to be tested in the [Test Plan] drop-down box. Here we hover our edited [Metal Bar Room Tensile Test], the name can be customized according to the customer's needs;
Check the parameters set by the test plan. After selecting the test plan, click the [View Test Parameters] button. The relevant parameters of the test plan settings will be displayed on the lower left. Check the contents of the test plan settings correctly. If you need to change, you can enter the edit. The test plan window is changed or a new test plan is added. I have set the parameters in advance here;
Enter the name of the saved file of the test data (ie, save the file). If there is no input, the software defaults to the current file name as the saved file name;
Measure and input the size of the sample and other user parameters; when measuring the sample size, it is generally necessary to measure the average value three times and input it into the software. If it is required to take the elongation after the break, the original gauge length is determined by the dot method. ;
Install the fixture, use the host keypad to manually control the movement of the beam, move the beam to the appropriate position according to the size of the fixture, install the fixture, set the limit switch, and clear the force sensor, that is, the force in the software Cleared, click the [clear] button next to the value displayed by the sensor;
The sample is clamped, and the position of the upper and lower chucks of the test machine is adjusted according to the length of the sample. After reaching the proper position, the sample is first installed in the chuck of the sensor end. The sample must be installed correctly to prevent deflection and clamping. For short phenomena, observe the correct installation and then clamp the collet at the other end of the specimen. (Note: The force sensor cannot be cleared after clamping, otherwise it will cause errors in the test results)
When the sample is clamped, if the display force value of the sensor is large, it is necessary to use the [Unload] button on the main keyboard to make the beam automatically adjust to automatically return the force sensor to the zero position. When returning to near zero, you can press the [Stop] button on the keypad or click the [Stop] button in the software to stop the beam adjustment. When the extensometer is clamped onto the sample, the extensometer must be installed on the sample. The middle part.
Run the test and confirm that the test parameters are correct and the [Run] button on the operation panel is full;
Switch the extensometer to reach the extensometer switching point, remove the extensometer according to the software prompt, or manually click the [extension meter switch] button to switch in advance; (Note: if using an extensometer for testing)
After the test is finished, loosen the clamp to remove the sample. If the sample breaks or reaches the specified stop condition, it will stop automatically. If manual forced stop is required, click the [Stop] button;
After inputting the measured fracture size, it is necessary to calculate the elongation after fracture in the reduction ratio of the section, measure the thickness after fracture, the width after fracture, and the gauge length after the break. In the software, [Allow modification] is marked, and the column of the selected data column needs to modify the user parameter. Enter the thickness after the break, the width after the break, and the gauge length after the break. Click the [Apply] button to calculate the elongation and other parameters. If you continue the test, repeat the steps 8~13 to generate the test report. The print test can be finished, offline, and exit. Software, turn off the computer;
