摘要

PURPOSE: A milling tool having an adjustable insert seat is provided to change the radial or axial position of a cutting insert by regulating the height of a seat surface and adjusting vertically a wedge plate by a set screw. CONSTITUTION: A milling tool having an adjustable insert seat is composed of a tool body(3) having at least one fixing unit connected to a work spindle driven to rotate; at least one insert seat(5) formed on the tool body for receiving a cutting insert(2) comprising a base surface, lateral sides, and a top surface(7), and installed with a wedge plate seat surface(19); a wedge plate(16) composed of a seat surface(17) contacted with the base surface of the cutting insert and a base surface aligned in an acute angle to the seat surface and arranged displaceably between the base surface of the cutting inset and the wedge plate seat surface of the inset seat; and a setting unit(27) for displacing the wedge plate for the cutting insert and the tool body according to a set reference. The base surface of the insert seat is contacted with the wedge plate seat surface.
