[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0034] A method for measuring thermal error of a grinding wheel spindle of a grinding machine of the present invention comprises the following steps:
[0035] (1) Non-contact displacement sensor setting
[0036] like figure 1 As shown, in order to measure the thermal deformation and inclination error in the two directions of the radial direction of the main shaft, two displacement sensors are installed along the Z axis in the X and Y directions respectively, wherein the first and third sensors 1 and 3 are located on the same plane, and the second , the fourth sensors 2 and 4 are located on the same plane. For the measurement of the thermal deformation of the grinding wheel spindle, according to the ISO230-3 evaluation method of the thermal effect of the machine tool, it is required to read the measurement value of the displacement sensor at least every ...
