PURPOSE:To eliminate the shaft move function of spindle thus to simplify the structure of spindle table by providing an absolute endface position measuring device on traverse tabel to directly measure the error of the referential surface of work when grinding. CONSTITUTION:Upon setting a work W between the centers 13, 14 and providing a taper grinding start command, central processng unit CPU will read out the setting L, M10, theta. Here, L is the movement of traverse table 17, M10 is the movement of grinding wheel G and theta is the turning angle of swivel table 19. Then an absolute endface measuring device T is advanced to measure the absolute positional shift (e) between the referential endfaces Wa of the work and a model work. Thereafter, the backing amount Lx of traverse table 17 is operated through (Lx-e) while the advancing amount Mx of the grinding wheel through (M10+e.sintheta) to grind the tapered section Wb on the basis of said amounts. Consequently, the structure of the spindle table can be simplified.
