WORKPIECE MACHINING APPARATUS |
摘要 |
A workpiece machining apparatus including a headstock to which a workpiece having a through-hole extending in a Z-axis direction is attached; a tool rest which is movable in the Z-axis direction and in an X-axis direction; and a rotary tool unit which is attached to the tool rest, is provided. The headstock has a support member which is movable in the Z-axis direction and which has a spindle side contact portion in an end portion in the Z-axis direction. The rotary tool unit has a tool body having a tool side contact portion with which the spindle side contact portion can come into contact in the Z-axis direction, and a rotatable tool which protrudes from the tool body. The rotating tool machines the workpiece by moving the tool body in the Z-axis direction in a state where the spindle side contact portion and the tool side contact portion are brought into contact with each other. |

1. A workpiece machining apparatus comprising:
a headstock to which a workpiece is attached when coordinate axes orthogonal to each other are set to a Z-axis and an X-axis; a tool rest being movable in the Z-axis direction and the X-axis direction; and a rotary tool unit attached to the tool rest, wherein the headstock has a support member being movable in the Z-axis direction, the support member has a spindle side contact portion in an end portion in the Z-axis direction, wherein the rotary tool unit has a tool body having a tool side contact portion with which the spindle side contact portion of the support member can come into contact in the Z-axis direction, and a tool protruding from the tool body and being rotatable around its own axis, and wherein the tool which is rotating machines the workpiece by moving the tool body in the Z-axis direction in a state where the spindle side contact portion and the tool side contact portion are brought into contact with each other. |
