horizontal speendle taper revision method and apparatus of numerical control machine tool

摘要

PURPOSE: A method and an apparatus for correcting a taper section of a horizontal spindle of a machine tool are provided to increase the workability of the machine tool and to improve the productivity by correcting the taper section without separating the taper section from the spindle. CONSTITUTION: A planing process(S1) is carried out for planing a contact portion of a taper section to which a chuck is attached for fixing tools. A taper measuring gauge having the same gradient as the taper section is coupled to the taper section so as to identically set the gradient of the taper section to an angle of a taper grinding stone(S2). Then, the taper grinding stone makes contact with the taper section. The spindle and a grinding machine are rotated while reciprocating the grinding machine in left and right directions so as to grind the taper section(S3).
