Universal Material Tensile Testing Machine ’s ball screw, load cell (sensors), motors, software and hardware, the drive system are important parts of the test machine, how to choose a quality testing machine, these five factors play a decisive role.

1.Ball Screw

Universal Material Tensile Testing Machine currently used screws have ball screws and trapezoidal screw. Generally speaking trapezoidal screw gap is a little larger, friction is a little larger, using life time a little shorter. At present, there are manufacturers on the market, in order to save costs for greater profits will use trapezoidal screw instead of ball screw.

2.Motor

High-quality electronic universal testing machine motor AC servo speed control system, Panasonic or Delta AC servo motor, stable and reliable performance, with over-current, over voltage, overload and other protection devices. There is also other electronic universal testing machine on the market using ordinary three-phase motor or variable frequency motor, the motor adopt analog signal control, control response is slow, positioning is not accurate, the general speed range is narrow there has low speed without high-speed or has low speed without high-speed, and speed control is not accurate.

3.Load cell (Sensor)

Load cell (Sensor) is the universal material testing machine precision and stability of the important components of force, in the current market, electronic universal testing machine sensor type have S-type, spoke type. Sensor internal resistance strain gauge accuracy is not high, fixed strain gauges with plastic anti-aging ability is not good, the sensor material will affect the accuracy of the sensor.

4.Software and Hardware

High-quality electronic universal testing machine with brand computer, with a fast speed, the interface is moderate, simple operation, can meet the needs of different materials test and measurement, according to national standards, international standards or industry standards to measure the physical properties of various materials testing.

5.Drive system

Universal Material Tensile Testing Machine drive parts have two kinds, First, arc synchronous gear with precision screw as assistant drive; second is the ordinary belt drive. The first drive method transmission smooth, low noise, high transmission efficiency, high precision, long service life. The second transmission can not guarantee the synchronization of the drive, so the accuracy, stability, etc. are not as good as the first drive system.
