摘要： An arbor for mounting a tool such as a drill or a grindstone to the end of a spindle of a machine tool and a machining method of employing such arbor. The arbor comprises a lubricant receiving member provided in the main body for receiving a lubricant supplied, and a lubricant passageway provided in the main body and extending between the lubricant receiving member and the tool mounting portion for flowing the lubricant from the lubricant receiving member to the tool mounting portion so as to supply the lubricant into an interior of the tool. The lubricant supplied from the spindle or another source of supply is allowed to flow through the lubricant receiving member and the lubricant passageway, and is supplied into an interior of the tool to ensure the appropriate supply of the lubricant to the area in which the tool acts upon the workpiece.
