Research on the Application of Hydrostatic Air Bearing on the Spindle of Standard Vickers Hardness Machine
In order to improve the accuracy of testing force of standard Vickers hardness machine,a Vickers hard-ness testing device with static pressure air floating spindle is designed in this paper.Based on the structural charac-teristics of the standard Vickers hardness machine and the requirements of the test force,the feasibility of applying the bearing to the standard Vickers hardness machine is discussed.The experimental results show that the test force and hardness value errors of the device meet the requirements of the specification,and can effectively improve the accuracy of Vickers hardness test.
