As a high-precision testing instrument, the internal configuration of the testing machine must be checked when purchasing. The internal configuration directly affects the service life of the testing machine itself. In many cases, the testing machine cannot operate due to the damage of some parts.

The rigidity of the main engine is the maximum that the main engine can bear. Do not buy those with the same tonnage that look very small. After a period of time, they will deform and be directly discarded, which will not work at all. Therefore, remember to be careful when choosing. It is the ball screw. The ball screw is the key of the testing machine. It is precisely because of it that the equipment can operate. It plays a role in transmission. If you buy it, you must make sure it is the ball screw, not the trapezoidal screw. In terms of motors, many people choose domestic motors, which are mainly cheap, but the quality and accuracy are relatively inferior to imported motors, so you must remember that the motors must be imported servo motors, because this motor has a good reputation and quality in the testing equipment.

In fact, the fixture does not have to be hydraulic, unless the weight of the sample measured by your testing machine is particularly large, because it is difficult for manual operation, while the manual fixture is different. It is relatively convenient to use and the operation is more reliable. Therefore, the best-selling fixture in the fixture industry is the manual fixture, which is more humanized for the equipment.
