Abstract
An NC lathe including a first spindle, a second spindle capable of holding a cut-off workpiece delivered from the first spindle, a second tool post on which a plurality of tools are attachable to machine the workpiece held by the second spindle, a product receiver provided on the second tool post, a Y2-axis motor capable of moving at least one of the second tool post and the second spindle in a Y2-axis direction, and an X2-axis motor capable of moving at least one of the second tool post and the second spindle in an X2-axis direction. The second tool post has a plurality of tool mounting parts where the tools are attachable. The tool mounting parts are aligned at intervals in the Y2-axis direction. At least one of the tool mounting parts is arranged in a position overlapping the product receiver with respect to the X2-axis direction.
Claims16
A lathe comprising:
- a first spindle rotatable on a first spindle axis;
- a second spindle rotatable on a second spindle axis and configured to hold a workpiece delivered from the first spindle;
- a tool post on which a plurality of tools are attachable, the tools configured to machine the workpiece held by the second spindle;
- a product receiver provided on the tool post, the product receiver comprising an inlet and a slope inside the product receiver, wherein the inlet is configured to receive the workpiece that has been machined with at least one of the plurality of the tools, and wherein the slope is configured to be used for workpiece discharge after machining, by having the workpiece fall into the slope inside the produce receiver, and guiding the workpiece to roll downwards to be discharged;
- a first driver configured to move at least one of the tool post and the second spindle in a first axis direction perpendicular to a direction of the second spindle axis;
- and
- a second driver configured to longitudinally move at least one of the tool post and the second spindle along a second axis direction, perpendicular to the direction of the second spindle axis and also perpendicular to the first axis direction;
- wherein the tool post has a plurality of mounting parts where the tools are attachable,
- the plurality of mounting parts are aligned at intervals in the first axis direction, and
- a first mounting part of the plurality of mounting parts is at least partially under the product receiver or over the product receiver.
