摘要： A machining apparatus capable of obscuring periodic machining irregularities. A workpiece W is mounted on a workpiece mounting surface of a worktable, and a tool T is supported by an elastic member (leaf spring) that is attached to a movable unit. A piezoelectric element is provided on the back of the leaf spring, and a driving voltage with irregular frequency and amplitude is applied to the piezoelectric element by a white noise generator during machining. Thus, a relative vibration displacement in a cutting-depth direction (vertical direction) is induced between the tool T and the workpiece W. In the case of a lathe apparatus, a relative vibration displacement is applied in the direction (horizontal direction) of a rotary axis of a workpiece fixture.

摘要： A simple, inexpensive waterproof/dustproof structure for a movable mechanism such as a machine tool apparatus or the like, providing a liquid reservoir formed between the inner wall of a stationary member and the outer wall of a movable member at a portion equivalent to the entrance of a gap between the stationary member and the movable member. The leading edge of the movable member moves through a liquid LQ that fills the liquid reservoir. The liquid LQ seals off the interior of the apparatus from the exterior to prevent the entry of mist, dust and other foreign matter. The gap may be made comparatively broad without affecting the ability to prevent the entry of foreign matter. The direction of movement of the movable member may be longitudinal, lateral, reciprocal, rotary, or a combination thereof, depending on the type of movable mechanism to which the waterproof/dustproof structure is applied. The liquid LQ may be a working fluid used by a hydraulic bearing or a machining fluid used by a machine tool.

摘要： A plurality of balancing structures are disposed in weight accommodation holes which extend in a radial direction and spaced at equal angles in a rotating plate constituting part of a rotating body on which a rotation object is mounted. A balancing weight having a male thread is disposed in each weight accommodation hole and is screwed into a female thread formed in the accommodation hole. A spring adjoining the weight is compressed by a stopper fixed in the weight accommodation hole at the outer end of the rotating plate. The weight can be turned with a tool inserted through holes provided in the spring and stopper to adjust the radial position of the weight and thereby balance the rotating body.

摘要： An air balance structure that compensates for the weight load of a movable member driven in a straight line along the vertical axis, with a simplified structure and at reduced cost. The box-shaped movable member has an open bottom that accommodates the stationary member therewithin, in which state the movable member is movably supported in the vertical direction by an air bearing created using a gap between the stationary member and the movable member. An air balance chamber that contains pressurized air is formed inside the movable member. After pressure-adjusted air is supplied from the outside to the gap from a jet port through a pipe inside the stationary member, the air flows into the air balance chamber. This flow seals the pressurized air inside the air balance chamber. Pressurized air exhaust is exhausted externally from an exhaust port through a pipe and a flow adjusting device.

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.
