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 pulse generation means that generates a pulse each time an XY movable member moves linearly by a certain amount relative to a base is provided. A workpiece and a light and dark pattern member are provided on the base. A tool, a light and dark pattern scanning sensor that scans the light and dark pattern and outputs a scanning signal, and a cutting means that moves the tool with respect to the workpiece in a cutting depth direction, orthogonal to the linear motion direction, are provided on the XY movable member. While the XY movable member moves relative to the base, the tool is moved by the cutting means in accordance with a logical AND operation performed on the scanning signal from the light and dark pattern scanning sensor and the pulse from the pulse generation means to perform machining.

摘要： A controller for a machine tool, capable of performing ultraprecision machining with high accuracy by performing correction allowing for a displacement of a spindle produced depending on a rotational speed. When the spindle is rotated at high speed, the cutting position of a tool attached to the spindle varies due to the influence of spindle fitting accuracy and of weight balance. By measuring the displacements in the X, Y and Z directions of the end of the tool attached to the spindle by means of non-contact displacement gauges, correction amounts are obtained in the manner associated with the rotational speed of the spindle, and stored in a storage device. In the process of machining, correction amounts are read depending on the speed of the spindle, and machining is performed according to program command values corrected using the correction amounts thus read. Even if the cutting position of the tool varies during high-speed rotation, machining is performed according to program command values corrected. Thus, ultraprecision machining can be carried out with high accuracy.

摘要： The invention provides a simplified holding structure for a tool for a machine tool that makes accurate tool holding possible. The tool shank is inserted through a through hole of a sleeve and into a tool shank insertion hole. The sleeve insertion part is inserted into a large-diameter part and fixed coaxially to the spindle with bolts or the like, so as to axially compress at least one annular elastic member provided on the large-diameter part. A first shank-supporting portion is provide inside the tool shank insertion hole and a second shank-supporting portion is provided on the sleeve through hole. A front end part of the insertion part is semicircular or trapezoidal in axial cross-section. The tool shank insertion hole, the sleeve through hole and the annular elastic member have cross-sections in directions perpendicular to the axis of the tool shank shaped that match the tool shank.
