摘要： The positions of at least three points, which are circumferentially, and equiangularly, offset from each other, of a peripheral face of a workpiece set on a rotary table are measured using a position detection probe. The amount of runout of the axis of the workpiece and a phase position of the workpiece, at which the runout amount is largest, are calculated from the measured positions of the equiangularly offset points. The rotary table is turned to set the largest runout phase position of the workpiece in a position opposed to a workpiece contact of a centering apparatus. The relative positions of the workpiece and a position detection block are calculated using the position detection probe. The workpiece is centered by moving a centering shaft member of the centering apparatus such that the workpiece contact pushes the workpiece by a distance corresponding to the runout amount.

摘要： In a tool spindle device, a tool head is slidably guided along guide members on a support table and is movable by a tool head feed mechanism. A tool spindle with a machining tool such as grinding wheel attached thereto is rotatably supported through antifriction bearings in the tool head. A lubrication mechanism is provided in the tool head for lubricating the antifriction bearings with oil air or oil mist. A space section is formed between the support table and the tool head to house the tool head feed mechanism and the guide members therein. A release passage is provided for releasing the oil air or the oil mist after lubricating the antifriction bearings, into the first space section therethrough to lubricate the tool head feed mechanism and the guide members housed in the space section.

摘要： A master servo motor and a slave servo motor that synchronously drive for rotation a master main spindle provided with a center that supports one end of a work piece and a slave main spindle provided with a center that supports the other end of the work piece are included.
