摘要： An electric path (E) is formed by connecting a spindle (11), a tool (12), a table (4), a base (2), a column (5) and a housing (13) including a capacitor (C0) having the spindle (11) and the housing (13) as electrodes, and electric current is sent to the electric path (E) by a current generator (51). An electro-capacitance change is detected by measuring a current value in the electric path (E) by an electro-capacitance detector (52) to detect a state of a bearing gap between the spindle (11) and the housing (13). No multiple sensors are necessary and the spindle state detector (50) can be simplified.

摘要： Metal powder is filled in a through-hole of a base member and a base porous body is formed by bonding the metal powder with each other and by bonding the metal powder to the base member so that an end surface on a bearing surface of the metal powder filled in the through hole is dented toward a compressed gas supply surface and at least a part of end surface on the compressed gas supply surface of the metal powder filled in the through-hole is dented toward the bearing surface. Subsequently, surface layer powder having smaller diameter than the metal powder is filled in the recess on the bearing surface to form a surface layer porous material layer by bonding the surface layer powder with each other and by bonding the surface layer powder to the base porous body 12 and the base member 10. The bearing surface is finished by removing face layer of the surface porous material layer by machining.

摘要： The object of the present invention is to provide a process for manufacturing a hydrostatic bearing of porous materials with less performance dispersion, at a high rate of productivity. A work piece is comprised of a base member and a housing. The base member is made of porous bronze and set on the front of the housing. A pressure chamber is formed in the rear side of the base material. The work piece is set in a cutting machine, where the surface of the base material is cut with a single crystal diamond bite. Then, molybdenum disulfide is applied together with a binder onto the surface of the base material, and then baked, thus forming a surface restrictor layer. The work piece is set back in the cutting machine, and the surface portion of the surface restrictor layer is cut with the single crystal diamond bite. After the cutting process, compressed air is supplied to the rear side of the surface restrictor layer via the base material. The flow rate of the compressed air is monitored. The depth of cut on the surface portion of the surface restrictor layer of the next cutting is controlled on the basis of the monitored flow rate so as to obtain a desired flow rate.

摘要： A linear motor device includes a primary linear motor member and a secondary linear motor member shaped of teeth of a comb with a plurality of projecting portions arranged at predetermined intervals. Recesses defined between the projecting portions are filled up with filler members for flattening a surface of the secondary linear motor member facing the primary linear motor member. Therefore, it is possible to remove chips from the surface easily. Since the filler members are made of low magnetical permeability material, the magnetic shielding between the neighboring projecting portion can be maintained. A linear motor device for a machine tool includes a bar type secondary linear motor member having both ends supported by an immovable member of the machine tool and a cylindrical primary linear motor member attached to a movable member of the machine tool. The secondary linear motor member is inserted into the primary linear motor member through a clearance so that the primary linear motor member can move in the axial direction of the secondary linear motor member. The primary linear motor member has cylindrical primary electrical wirings surrounding the whole periphery of the secondary linear motor member. An attractive force between the primary and secondary linear motor members acts over a whole periphery of the secondary linear motor member uniformly. Therefore, the resulting radial forces onto the secondary linear motor members are canceled each other.

摘要： There are disclosed a method of and an apparatus for controlling a track position error of a load such as the workpiece table of a multi-axis machine tool. A feed pulse signal for driving the load is added to a deviation of a present position signal detected of the load from a commanded position signal dependent on the polarity of the deviation. The deviation of the added feed pulse signal from the present position signal of the load is determined, and a drive signal for driving the load is derived from a deviation signal indicative of the last-mentioned deviation. A drive source for driving the load is controlled with the deviation signal.
