摘要： An ultra-precision machine tool capable of accurately detecting a machining start position, in which movable axes are supported by fluid bearings. A workpiece is mounted on a rotary table of a B axis, and the rotary table is mounted on an X axis that is a linear motion axis. A tool is mounted on a Y axis. The Y axis is mounted on a Z axis. The X axis is moved reciprocally each time the Z axis is moved a predetermined amount, a machining surface of the workpiece is scanned, and it is determined whether or not position deviation of the X, Y and B axes reaches or exceeds a reference value. The Y axis is driven and the tool is moved toward the workpiece a predetermined amount, and the above-described scan is performed. When the position deviation of the X, Y and B axes reaches or exceeds the reference value it is determined that contact between the tool and the workpiece has occurred, and this contact point is stored as the machining start position, the Y axis is skipped, and the tool is moved a predetermined amount in a direction away from the workpiece, thus enabling a point of maximum protrusion from the machining surface of the workpiece to be simply detected as the machining start point.

摘要： A machine tool capable of automatically correcting an orientation of a workpiece or machining attachment based on detection results from position detectors that the machine tool inherently has. The machine tool comprises: position detectors; position deviation determining means; contact detection means that detects a contact between a probe and a surface of the workpiece or the machining attachment based on a position deviation; movable axis stopping means; coordinate value detection means; inclination determining means; and correction means. The inclination determining means moves linear axes to perform detection of contacts between the probe and the surface of the workpiece or the machining attachment at least two different points, and determines an inclination of the workpiece or the machining attachment using the obtained coordinate values. The correction means corrects a mounting error of the workpiece or the machining attachment, or corrects the machining program based on the determined inclination.

摘要： A machine tool is fitted with a position detector for detecting a position of a moving axis of the machine tool and an on-machine measuring device for measurement on the machine tool. An axial position detection signal output from the position detector and a measurement signal output from the on-machine measuring device are received through interfaces by a numerical controller that controls the machine tool. These interfaces are designed so that the numerical controller receives the axial position detection signal and the measurement signal with the same timing.

摘要： Materials with different thermal expansion coefficients are selected individually for a bearing guide and a slider that constitute a fluid bearing. The guide and the slider are combined in close contact with each other (i.e., with a zero bearing clearance between the two) in a temperature environment different from a temperature at which the fluid bearing is actually used. In consequence, the bearing clearance at the operating temperature can be adjusted based on a difference from the temperature for the fluid bearing assembly.
