description The invention discloses a method for judging abrasion of a diamond cone pressure head for a Rockwell hardness tester, belongs to the field of metal part detection and analysis, and particularly relates to the method for judging abrasion of the diamond cone pressure head for the Rockwell hardness tester. The invention aims to overcome the defects of the abrasion judgment method of the diamond cone pressure head for the Rockwell hardness tester. The method comprises the following steps: 1, calibrating the Rockwell hardness tester; 2, when the deviation between the arithmetic average value and the hardness value of the standard hardness block is beyond +/-HRC1.5 or the difference value between the maximum value and the minimum value of the detected hardness is greater than HRC 0.8, and the calibration of the Rockwell hardness tester is unqualified, immediately judging the integrity of the diamond cone pressure head; and 3, when the Rockwell hardness tester is calibrated to be qualified, if the following three co
