| Abstract: | A new method of testing the spindle static stiffness of the vertical machining center and the experimental study to this method were introduced. Took the vertical machining center XH7132 as the research object, strain type force sensor was used to test the force and least square method was used as calibration method. The calibrated strain type force sensor, resistance strain gauge and inductive micrometer have been used to test the static stiffness, then the spindle static stiffness values can be obtained. |
