Many experimental machines are available on the market. How can we choose the right one? We can consider the following elements: electronic experimental machine software and hardware, ball screw, motor, sensor, and transmission system, which are all crucial components. The transmission system uses an arc synchronous gear belt and precision ball screw transmission, ensuring smooth operation, low noise, high transmission efficiency, high precision, and a long service life.

Sensors are a crucial component for the precision and stability of the testing machine's force measurement. The types of sensors available in the market for electronic testing machines include S-type and spoke-type. The motors of electronic testing machines are equipped with a communication servo speed control system, utilizing Panasonic's communication servo motor, which offers stable and reliable performance, including overcurrent, overvoltage, and overload protection features.

The electronic experimental machine features screw impact tests for both ball screws and trapezoidal screws. Generally, trapezoidal screws have a larger pitch, greater friction, and a shorter lifespan. The control system software operates on an operating system platform, offering fast operation speed, a user-friendly interface, and simple operation, meeting the varying measurement needs of different materials.

 Upon investigating the suitability of the above points, our company's experimental machines can be guaranteed, having undergone national standard testing. The role of lubricating oil in the experimental machine is significant, with several aspects for the fully automatic pressure testing machine. This article briefly introduces the primary function of lubrication, which is to cool the equipment, as good lubrication can remove the heat generated by friction.

Secondly, lubrication can reduce the friction between the moving surfaces of concrete and extend the service life of components. Furthermore, the hydraulic system of the pressure testing machine, where the piston ring outer surface and the cylinder sleeve inner surface are concerned, lubrication can act as a seal due to the formation of an oil film during their relative movement. Therefore, it is crucial to pay attention to lubrication when operating the testing machine.
