Abstract
A machining systemcomprises a lathehaving end portion supporting mechanismsfor supporting an elongated workpiece W horizontally, center restsfor supporting the middle portion of the workpiece W, an adjustment mechanism for adjusting the supported position of the workpiece W by adjusting the height positions of the center rests, a tool rest, and a control device, and a non-contact measuring devicefor measuring the deflection amount of the workpiece W at portions thereof supported by the center restswhen the workpiece W is rotated. The control deviceis configured to adjust the height positions of the center restsby controlling the adjustment mechanism on the basis of the measured deflection amount, so that the height positions of both end portions of the workpiece W being rotated and the middle portion thereof become the same.
