摘要： PROBLEM TO BE SOLVED: To provide a fluid bearing with uniform depths of bearing grooves and a method of forming the bearing. SOLUTION: Pipe members 32 opening at both ends are inserted into holes for supplying fluid to a fluid bearing surface 34 on a main guide member 33. Pressurized fluid flows out to the fluid bearing surface from fluid spout holes 30. Bearing grooves 31 are formed around fluid spout holes 30. The main guide member 33 and the pipe members 32 are made of different materials. An anodizing process is applied on surfaces of the main guide member 33 and the pipe members 32 to form thin coating layer. Thickness of the coating layer on the main guide member 33 formed by the anodizing process is different from thickness of the coating layer on the pipe members 32 formed by the anodizing process since the main guide member 33 and the pipe members 32 are made of different materials. A material on which a coating layer grows quickly by anodizing process is selected for a guide member 11 and a material on which a coating layer grows more slowly than the material of the guide member 11 is selected for the pipe members 32.

SOLUTION: A workpiece W is mounted on a workpiece mounting surface 11 of a work mounting block 10, and a tool T is supported by an elastic member (leaf spring) 22 that is attached to a movable unit 21. A piezoelectric element 30 is provided on the back of the leaf spring 22, and a driving voltage with irregular frequency and amplitude is applied to the piezoelectric element by a white noise generator 41 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 the work mounting block.

摘要： PROBLEM TO BE SOLVED: To provide a machining apparatus, adapted to machine by high-speed reciprocation, and reducing the force required for reversing the moving direction. SOLUTION: A guide member 2 is born on a base 1 by a fluid bearing, A slide member 3 having a tool 13 is supported on the guide member 2 by a fluid bearing structure. A coil 7 is disposed in the slide member 3, and a driving permanent magnet 6 is disposed at the stroke end of reciprocation of the slide member on the guide member 2 to form an iron core 8 between them. Thus, a linear motor is constructed. A reversing permanent magnet 5 is disposed at both ends of the slide member 3, and a reversing permanent magnet 4 is disposed at the stroke end in the guide member 2. When the slide member 3 is reversed in the moving direction, the slide member is accelerated by repulsive force of the reversing permanent magnets 4, 5, so that even the linear motor having small thrust force of the above constitution can drive the slide member to perform machining. High-accuracy linear groove machining can be performed without heat generation, thrust ripple and cogging. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To put a brake without needing a special braking device and without affecting a fluid bearing surface.
SOLUTION: In this fluid bearing, a slide member 10 linearly moved while guided by a guide member 11, is supported by the fluid bearing surface 15. The guide member 11 projects downward from an opening portion formed on an lower surface of the slide member 10, and its side wall surface as a braking surface 12 is closely kept into contact with a braking surface 13 of the slide member 10. When the fluid of sufficient pressure is supplied to the fluid bearing surface 15, the slide member 10 is deformed as shown in Fig. 2(b), a clearance is formed between the braking surfaces 12, 13, and the slide member 10 is supported by the fluid bearing surface 15 in a non-contact state with the guide member, and allowed to be linearly movable. When the pressure of pressure fluid is lowered, the braking surfaces 12, 13 are closely kept into contact with each other as shown in Fig. 2(a), and the slide member 10 is braked. Thus the fluid bearing capable of being braked without needing the special braking device and damaging the bearing surface, can be provided.

Even if the clearance 30 is made comparatively wide, foreign matter intrusion preventing action is achieved. The direction of movement of the movement member 20 includes vertical, left and right, forward and backward, rotation directions or synthesis of them in accordance with type of the movable mechanism to which the waterproof and dustproof structure is applied. Working fluid used in a fluid bearing and working fluid used in a machine tool can be diverted to the liquid LQ.

摘要： PROBLEM TO BE SOLVED: To provide a micro-positioning device and a machine tool position posture correcting method exhibiting machine rigidity and capable of achieving positioning accuracy in nano-order.
SOLUTION: A driving element is constituted by two of piezo elements P1 and P2 arranged on a straight line along the expansion direction.

An interval L is formed between the piezo element P2 and the movable member 2. When elongation displacement amounts of the piezo elements P1 and P2 are a1 and a2 respectively, the voltage applied to the piezo elements P1 and P2 is controlled as follows; a1+a2=a≥L. The movable member 2 can be positioned in a position within the maximum stroke (a) in nano-order. The driving element is arranged in the perpendicular direction, and the positioning device of 2-freedom or 6-freedom by including a rotating shaft can be achieved.

摘要： PROBLEM TO BE SOLVED: To provide an air hydrostatic bearing having extremely small vibration while bearing rigidity is maintained. SOLUTION: A slide 2 is supported against a guide member 1 with a bearing gap 3. Air is fed into the bearing gap 3 through a primary pipe 11, a diverged pipe 11, and an orifice 12 which are arranged on the slide 2. Forms of pipes such as a size in diameter, a shape, and numbers or the like are determined so that Reynolds number becomes not larger than 2,000 at each part of the primary pipe 10, the diverged pipe 11, the orifice 12, and the bearing gap 3 (the diameter of the primary pipe 10 which is apt to generate a turbulent flow is formed larger) so that a turbulent flow is not generated. Because no turbulent flow is caused at each part, vibration is not generated, and the air hydrostatic bearing being stable at precision of not greater than one nanometer is realized.

摘要： PROBLEM TO BE SOLVED: To provide a tool holder capable of performing motion close to lathe turning, and to provide a machine tool provided with the tool holder.SOLUTION: A tool 2 is mounted on a turntable 12 via a first beam 14 having some rigidity. The first beam has its one end secured to the turntable 12 so that its axis overlaps a rotation center axis 4, and to the other end of the first beam, the tool is secured. A first weight 6 is secured to the other end side portion of the first beam. In the stationary state of the turntable, the first weight 6 is secured to the first beam in a position not superimposed on the rotation center axis 4 and, thereby, when the turntable is rotated, by centrifugal force Fc acting on the first weight, the other end of the first beam on the side where the tool is secured is shifted outward from the tool rotation center axis. Thereby, the tool is rotated around the tool center axis with a tool rotation radius Rt and the tool rotation radius Rt changes in accordance with the rotation speed of the turntable.
