Stepping electric machine drives chain to rotate stepping,and go through probe respectively and testing ,after testing ,when it is rotating ,if qualified ,then the machine will accumulate testing  samples,if is not qualified, then it will be eliminated by air cylinder. The electric control mode uses the light and electricity switch and control box to realize logical control. By outputting of realizing testing signal to testing main engine and probe. 

Main engine and probe use preventive multi-frequency and flat pannel display to predict two modes to realize testing signal output

1、Adopting dot mode differential probe

2、Detecting 0.05MM deep flaw

3、Detecting surface is two end surface

4、Detecting speed is 1.5 seconds per piece

5、Equipment noise <60db。Power consumption <500W（220V）

6、Automatic supply、sorting 、counting

7、There is no damage on accessories after eddy flaw detection

8、No auxiliary process such as wash 、demagnetization
