摘要： A multi-spindle unit for holding and rotating a plurality of rotary cutting tools has a unit body fixed to a first spindle of a machine tool, a rotatable shaft concentric with the unit body, and a plurality of secondary spindles each having a tool mounting portion at one end thereof. The rotatable shaft is coupled at one end portion to the unit body for receiving a torque from the holder body, the rotatable shaft being displaceable relative to the holder body. A rotation transmitting mechanism is provided to transmit a rotary motion of the rotatable shaft to the secondary spindles. A positioning member is fixedly disposed radially outwardly of the first spindle, and a cylindrical casing is disposed radially outwardly of the rotatable shaft such that the casing and the shaft are rotatable relative to each other. The casing is engageable with the positioning member for positioning thereof by the positioning member, and thereby positioning the secondary spindles.

摘要： An end milling tool having an elongate body which has two flutes defining two elongate lands extending generally in an axial direction of the body. The two lands have first and second flute surface each facing in a direction of rotation of the end mill. The end mill carries at least two peripheral-cutting inserts for peripheral milling, an inner drilling insert for cutting a radially inward portion of a hole, and an outer drilling inserts for cutting a radially outward portion of the hole, each insert being replaceable and of a generally flat configuration having a back face held in contact with the appropriate surface of the body, and a front face opposite to the back face and including a cutting edge. The peripheral-cutting inserts are disposed in a staggered manner alternately in the first and second flute surfaces, such that the first flute surface carries the peripheral-cutting insert which is nearest to the end face of the body. The inner drilling insert is disposed on the end face of the land having the first flute surface, and the outer drilling insert is disposed in an area of the second flute surface adjacent to the end of the body.

摘要： A holder for a rotary cutting tools has a holder body fixed to a spindle of a machine tool. A rotatable shaft concentric with the holder body and having a tool-mounting portion at one end thereof is coupled at its other end portion to the holder body to receive torque from the holder body. The rotatable shaft is so mounted as to be radially displaceable and inclinable relative to the holder body. A positioning member is fixedly disposed on the machine tool body radially outwardly of the spindle. A cylindrical casing disposed radially outwardly of and rotatably engaged with the rotatable shaft such that the casing and the shaft are rotatable relative to each other, the casing being engageable with the positioning member for accurate positioning thereof by the positioning member, and thereby positioning the rotatable shaft. The holder may further have a circumferential lock mechanism for locking the casing and the holder body to prevent relative rotation between the casing and the holder body when the holder is not attached to the spindle, and for allowing relative rotation after the holder has been attached to the spindle.

摘要： A tool holder for holding a rotary cutting tool, attachable to a spindle of a machine tool, has a holder body fixed to the machine spindle. A rotatable shaft having a tool-mounting portion is coupled to the holder body such that the shaft is axially and radially displaceable relative to the holder body. A positioning member is fixedly disposed on the machine tool body radially outwardly of the machine spindle. A casing is disposed radially outwardly of the rotatable shaft such that the casing and the rotatable shaft are rotatable relative to each other, the casing being engageable with the positioning member to accurately position the rotatable shaft when the holder body is fixed to the machine spindle. A guide bushing is fixedly supported at one axial end portion of the casing remote from the holder body. The guide bushing has a bore which is engageable with an outer circumferential surface of a guide portion of the cutting tool held by the tool-mounting portion of the rotatable shaft, thereby rotatably guiding the cutting tool.
