Claims

[Scope of utility model registration request]

A rotationally driven spindle, a main body attached to the spindle, a slide table placed on the main body, and a cam inserted through the spindle and formed on the slide table are engaged to move up and down within the spindle, and the slide table is moved up and down. A grooving head consisting of a camshaft that slides on the main body, a presser foot attached to the main body, a holder for a grooving cutter that can be attached to a slide table, and a stopper that restricts the forward and backward ends of the slide table, A cylindrical portion is integrally molded on the presser foot, and the cylindrical portion is oil-tightly fitted and fixed to the outer peripheral surface of the main body, and an oil hole that opens into the slide table is bored in the longitudinal direction of the camshaft, Instead of a holder for a grooving cutter, a rotary tool with an oil hole can be mounted on the slide table on the same axis as the spindle via a rotary tool or mounting holder, and the pressurized oil sent through the oil hole on the camshaft can be mounted on the slide table on the same axis as the spindle. A grooving head characterized by communicating with an oil hole of a rotary cutting tool.
