摘要： This invention relates to an apparatus and method for sensing a thrust load applied to a spindle of a machine tool. The object of the invention is to generate a signal representing the thrust load alone, exclusive of other forces such as frictional resistance within the spindlehead feeder, etc. so as to accurately measure the thrust load. According, to one disclosed embodiment, a first pressure sensor is arranged between a thrust bearing supporting the spindle and a surface on the spindle support and a second pressure sensor is arranged between a second surface on the spindle support and the machine tool frame. Each of the pressure sensors may be, for example, a piezo-electric film pressure sensor.

摘要： A machine tool body (1) is equipped with a spindle (9) which can move vertically along the Y axis. A first table (14) on a bed (10) of the machine tool body (1) is movable horizonally in the Z direction and can move toward the tool (11) held by the spindle (9). A second table (15) set on the first table (14) can move in a horizontal direction at a right angle to the moving direction of the first table (14). A first rotary table (16) set on the second table 15 can be indexed about the rotation axis (RO) and has an extension portion (17) extending upwardly. The second rotary table (19) set on a side surface (16) of the extension portion (17) can be indexed about a rotation axis (QO) while it holds fixedly a workpiece (W). A workpiece feeding means (4) is used to load a workpiece (W) onto the second rotary table (19) and after machining thereof unload each workpiece (W) for the second rotary table (19).
