Rotary bending fatigue testing machine

用途：

It is mainly used for the fatigue performance test of oil tempered high quality alloy steel wire, the intermediate product of spring。

特点：

Servo motor drive, speed stepless adjustment;

The full digital closed-loop control system can realize the requirements of load and deformation closed-loop control;

Counting function, accurately record the number of wire rotation;

The test speed can be changed during operation;

The loading force can be changed during operation;

Automatically stop after sample failure and save data;

The test can be cooled by blowing air;

The loading force value is stable, and the force value of the two loading points beats ±3N。
