Improvement on Processing Technology of High Frequency Fatigue Specimens

Aiming at problems of cumbersome processing,small amount of feed and low processing efficiency of high frequency fatigue specimens with circular cross section,by optimizing the processing technology,improving the processing equipment,optimizing the transitional arc of screw connection bottom and increasing polishing process,the existing processing of high frequency fatigue specimens were greatly improved.The results show that the improved processing method could not only improve processing efficiency and test success rate and reduce test cost,but also greatly improve accuracy of the test results.
