Claims

[Scope of Claim for Utility Model Registration] (1) A grinding machine equipped with a grinding wheel on the main shaft, which is arranged in a column and is rotatable within a range where the main shaft has an angle of depression of 10° from a substantially horizontal position. a main shaft support for supporting the main shaft; means for finely adjusting the inclination angle of the main shaft within the rotation range; a horizontal position measuring means for measuring when the main shaft has reached a horizontal position; A grinding machine with an inclined spindle head and a locking means for inhibiting the grinding at an inclination angle of . (2) A grinding machine with an inclined spindle head according to claim (1) of the utility model registration, which is provided with a stopper for regulating the rotation range of the spindle. (3) The means for finely adjusting the inclination angle of the main shaft is capable of moving forward and backward in a direction away from the center of rotation of the main shaft, and includes a ball nut that transmits rotational force to the main shaft, a ball screw that moves the ball nut, and a ball screw that moves the ball nut. and a means for rotating a screw. (4) Practical use characterized in that the column is shifted from the center of the grinding machine in either the left or right direction so that the main shaft attached to the side surface of the column via the main shaft support is located at the center of the grinding machine. A grinding machine with an inclined spindle head according to claim (1) of patent registration.
