How to choose the internal structure of the tensile tester

Tension testing machines are widely used and the products on the market are also uneven. What issues should we pay attention to when purchasing again? How to choose internal structures? The following editor will give a brief guide to the main components:

1. In terms of motors, many people choose domestic motors, mainly cheap, but their quality and accuracy are relatively inferior to imported motors. So you must remember this point that the motor must be imported servo motors, because this motor has a good reputation and quality in the testing equipment.

2. Ball screw. Bead screw is the key to the equipment. It can be operated because of its equipment. It plays a driving role in it. If you purchase it, you must make sure it is a ball screw, not a trapezoidal screw.

3. The encoder is best imported.

4. Fixtures. In fact, fixtures do not have to be hydraulic, unless the weight of the sample you tested is particularly large, because this is difficult to operate by manual means, and manual fixtures are different. They are relatively convenient to use and more reliable to operate. Therefore, the most popular one in the fixture industry is manual fixtures, which are more user-friendly to the equipment.

5. The host stiffness is the maximum amount that the host can withstand. Don’t buy it if it looks very small. It will deform after using it for a period of time and will be discarded directly, and it will not work at all. Therefore, remember to deal with this carefully when choosing this.
