Cutting apparatus
A cutting apparatus includes a magazine including a holder to hold a machining tool. The holder includes a container, a magnetic body, and an intermediate member. The container holds a flange of the machining tool. The container includes in its bottom surface a first insertion hole through which a tool body of the machining tool is to be inserted. The magnetic body is disposed under the container. The magnetic body includes a second insertion hole through which the tool body is to be inserted. The intermediate member is disposed inside the second insertion hole. The intermediate member includes a third insertion hole through which the tool body is to be inserted. A length of the intermediate member in a height direction is equal to or longer than a length of the magnetic body in the height direction. The intermediate member is made of a non-magnetic material.
1. A cutting apparatus for cutting a workpiece by rotating a machining tool including a rod tool body and a flange disposed on the tool body, the cutting apparatus comprising:
a magazine including a holder to hold the machining tool; wherein
the holder includes:
a container to hold the flange, the container including in a bottom surface a first insertion hole through which the tool body is to be inserted;
a magnetic body disposed under the container, the magnetic body including a second insertion hole through which the tool body is to be inserted; and
an intermediate member disposed inside the second insertion hole of the magnetic body, the intermediate member including a third insertion hole through which the tool body is to be inserted; wherein
assuming that a direction in which the machining tool is to be inserted into the holder is a first direction, a length of the intermediate member in the first direction is equal to or greater than a length of the magnetic body in the first direction; and
the intermediate member is made of a non-magnetic material.
2. The cutting apparatus according to claim 1 , wherein the container and the intermediate member are integral with each other.
3. The cutting apparatus according to claim 1 , wherein the container includes:
a bottom plate provided with the first insertion hole; and
a side plate extending upward from an end of the bottom plate.
4. The cutting apparatus according to claim 3 , wherein the intermediate member is connected to an underside of the bottom plate.
5. The cutting apparatus according to claim 3 , wherein assuming that a direction perpendicular to the first direction in a front view is a second direction, a thickness of the intermediate member in the second direction is larger than a thickness of the bottom plate in the first direction.
6. The cutting apparatus according to claim 1 , wherein assuming that a direction perpendicular to the first direction in a front view is a second direction, the length of the magnetic body in the first direction is shorter than a length of the magnetic body in the second direction.
7. The cutting apparatus according to claim 1 , wherein the intermediate member includes a protrusion protruding downward of the magnetic body.
8. The cutting apparatus according to claim 7 , wherein the holder includes a spring disposed under the magnetic body and at least around the protrusion of the intermediate member.
9. The cutting apparatus according to claim 8 , wherein the spring is made of a non-magnetic material.
