Milling/cutting tool and processing apparatus
Provided is a milling/cutting tool including: a tool main unit that is rotated about an axis; and a plurality of tips that are disposed at one end surface of the tool main unit with spacings therebetween in a circumferential direction about the axis of the tool main unit, wherein the individual tips are disposed so that turning rake surfaces thereof are inclined in the axial directions.
1. A milling/cutting tool comprising:
a tool main unit that is rotated about an axis;
a plurality of tips that are disposed with spacings therebetween in a circumferential direction about the axis of the tool main unit;
wherein all of the plurality of tips are disposed so that turning rake surfaces thereof face an axial direction;
wherein the milling/cutting tool is configured to perform turning and milling; and
wherein all of the plurality of tips are circular tips, the plurality of circular tips being disposed at a distal-end surface of the tool main unit, and wherein each circular tip of the plurality of circular tips has a truncated-conical shape having a large-diameter surface on a distal-end side and a small-diameter surface on a proximal-end side, the large-diameter surface of each of the circular tips disposed facing a center axis of the tool main unit.
2. The milling/cutting tool according to claim 1 , wherein:
the plurality of tips comprise at least two first tips and at least two second tips that are disposed in the circumferential direction about the axis in an alternating manner; and
the first tips are disposed at positions that are retracted in radial directions and the axial directions with respect to the second tips.
3. A processing apparatus comprising:
a milling/cutting tool comprising:
a tool main unit that is rotated about an axis;
a plurality of tips that are disposed with spacings therebetween in a circumferential direction about the axis of the tool main unit;
wherein all of the plurality of tips are disposed so that turning rake surfaces thereof face an axial direction; and
wherein the milling/cutting tool is configured to perform turning and milling;
wherein all of the plurality of tips are circular tips, the plurality of circular tips being disposed at a distal-end surface of the tool main unit, and wherein each circular tip of the plurality of circular tips has a truncated-conical shape having a large-diameter surface on a distal-end side and a small-diameter surface on a proximal-end side, the large-diameter surface of each of the circular tips disposed facing a center axis of the tool main unit.
4. The processing apparatus according to claim 3 , comprising:
a motor that rotates the milling/cutting tool about the axis;
a main shaft that rotates a processing subject to be processed about an axis disposed at a skew position with respect to the axis of the milling/cutting tool; and
wherein the milling/cutting tool and the processing subject are moved relative to each other.
5. The milling/cutting tool according to claim 2 , wherein:
the large-diameter surface of each circular tip of the plurality of circular tips constitutes a rake surface for performing turning, and an outer circumferential surface of each of the circular tips constitutes a rake surface for performing milling.
