Title:
GRINDING MACHINE AND GRINDING METHOD
Document Type and Number:
Japanese Patent JP2019076961
Kind Code:
A
Abstract:
To provide a grinding machine and a grinding method which can improve grinding processing accuracy.SOLUTION: A control device 31 of a grinding machine 1 determines an eccentricity amount d of a shaft line of a work-piece W to be grinding-processed corresponding to deformation force F applied in a radial direction of the inputted work-piece W to be grinding-processed while referring to a correlation between the predetermined deformation force F applied in the radial direction of the work-piece W and the eccentricity amount d of the shaft line of the work-piece W, and controls feed motion of feeding devices 24 and 25 while adding the eccentricity amount d, so that the work-piece W to be grinding-processed is grinding-processed with a grinding wheel 28.SELECTED DRAWING: Figure 12
