MOBILE PRECISION BORING TOOL
专利汇可以提供MOBILE PRECISION BORING TOOL专利检索，专利查询，专利分析的服务。并且A mobile boring tool of this type is secured to a place to be bored of a large workpiece and is used for carrying out precision boring operations by means of a tool through which a liquid lubricant is supplied to the tool cutters. The tool has a tool spindle (1) with a tool holding fixture (2) through which lubricant is supplied, as well as a drive for rotating and axially advancing the tool spindle. In order to increase machining precision and improve lubricant dosage, the boring tool has besides the rotary drive (15) a separate drive (25) for advancing the tool spindle, as well as a measurement system (24) for sensing the advance distance. The advance drive (25) is controlled by a computer depending on the axial advance distance, so that the tool spindle is driven by the rotary drive at a predetermined on-load speed of rotation or load torque. Lubricant supply is controlled depending on the predetermined on-load speed of rotation or load moment and on the advance distance.，下面是MOBILE PRECISION BORING TOOL专利的具体信息内容。
