Since the notch is provided in the front end corner portion of the base, the operator approaches the spindle head by entering the notch. As a result, it is easy to confirm the workpiece placed on the table.

Therefore, if this five-axis deburring apparatus is used, the teaching operation can be easily performed when deburring the workpiece. In particular, the horizontal movement of the spindle head relative to the table is performed by the movement of the spindle, and the table does not move in the horizontal direction. Therefore, even if a notch is formed on the side of the table, the table does not interfere. Is. Furthermore, since the table moves back and forth, an operator positioned in front of the base can easily set and reset the workpiece.

In this case, if a replacement tool magazine is installed in the vicinity of the notch in the base, the operator can easily check the replacement state of the processing tool by entering the notch.

Further, if the spindle head can be tilted to the notch side, an operator who has entered the notch always sees the tip of the processing tool during processing, and the teaching is easy to perform. .

Furthermore, the spindle head processing tool can be a deburring tool.

The five-axis deburring apparatus according to the present invention has the most main features in the following configuration when implemented.

The “five-axis direction” corresponds to the X and Y axes that are horizontal to the top surface of the table, the Z axis that extends perpendicular to the top surface, the rotation of the table, and the inclination of the spindle head with respect to the table. These are controlled by NC (numerical control).

It is preferable that the “spindle head” can be inclined only to the notch side.

A deburring tool is used as the “spindle head processing tool”, but is not limited thereto.
