GRINDER AND GRINDING METHOD

Japanese Patent JP2017019071

A

PROBLEM TO BE SOLVED: To provide a grinder which can improve a life of a tool when grinding a workpiece which is formed of a difficult-to-grind material, and can easily remedy the tool on the grinder, and a grinding method.SOLUTION: A grinder 1 comprises: an annular tool 90 having an annular cutting edge; a tool spindle 71 which rotates around an axial line Rt of the annular tool; a workpiece holding table 10 for holding a workpiece W; and a control device 80 which controls a relative position between the tool spindle and the workpiece holding table, and the rotation of the tool spindle. The control device is arranged while having such a relative positional relationship that an external peripheral face of the annular tool becomes a rake face and an end face becomes a flank face, grinds the workpiece while rotating the annular tool, changes a relative angle between the annular tool and the workpiece to an angle which is different from an angle at processing when the remedy of the annular tool becomes necessary, makes the annular tool contact with the workpiece while rotating the annular tool, and remedies the annular tool.SELECTED DRAWING: Figure 1
