摘要： PROBLEM TO BE SOLVED: To provide a spindle capable of suppressing the generation of heat and vibration in a center-through coolant system.
SOLUTION: A coolant supply member 5 having a nozzle 5a is fixed to a housing 2 of the spindle 1. A rotating hollow shaft 3 supported to the housing 2 by a fluid bearing 9 is formed with a tapered hole 7 large in diameter on the mounting side of a tool 4. The nozzle 5a is inserted in a non-contact state into the tapered hole 7 of the hollow shaft 3 and fixed. A coolant supplied into the rotating hollow shaft 3 from the nozzle 5a advances to the diameter enlarged tool side by centrifugal force caused by rotation, and is discharged into the vicinity of a workpiece machining point of the tool 4 through a discharge hole 8. Since the coolant can be supplied in a non-contact state into the rotating hollow shaft 3 and discharged into the vicinity of the machining point, heat generation and vibration of the spindle can be suppressed.

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.

摘要： PROBLEM TO BE SOLVED: To prevent mist occurring in a machining area of a machine tool equipped with an air bearing, from entering the interior of a machine.
SOLUTION: According to the structure of the machine tool, a machine cover is formed into a sealing structure without a gap, and therefore, air discharged from the air cylinder increases internal pressure of the interior of the machine, which then concentratively flows from the interior of the machine, via a labyrinth space formed in the air bearing portion, to the machining area. By forming a vent hole communicating with the atmosphere in the machining area, an air current discharged via the vent hole to the atmosphere is produced, and therefore, mist occurring in the machining area is prevented from flowing from the labyrinth space into the interior of the machine.

摘要： PROBLEM TO BE SOLVED: To provide an air spindle preventing occurrence of vibration.
SOLUTION: A face on which air for driving a rotor 1 of the air spindle abuts is a smooth face 1a. Air for driving is injected in the direction in which the rotor 1 is rotated at a predetermined angle for the smooth face 1a from a nozzle. The rotor 1 rotates due to viscosity of air. The rotor 1 has faces 1c, 1e constituting a hydrostatic air bearing receiving it in a housing and a bracket constituting the spindle. Since air for driving injected from the nozzle is sprayed on the smooth face 1a, this air spindle has no blade as a conventional air turbine spindle, and there is nothing crossing air jet stream, thereby causing no vibration. Blade machining is unnecessary, and this air spindle can be manufactured at low cost. Since vibration does not occur, machining by use of this air spindle can realize highly precise machining.

摘要： PROBLEM TO BE SOLVED: To machine a work with high accuracy by correcting displacement of a spindle caused depending on the rotating speed in a machine tool for ultraprecise machining.
SOLUTION: In this tool 2 fitted to the spindle 1, the cutting position is displaced when the spindle 1 is rotated at a high speed due to fitting accuracy of the spindle 1 and the influence of weight balance. The tip position of the tool fitted to the spindle 1 is measured on the displacements in the directions of X, Y and Z by non-contact type displacement measuring devices 6x, 6y and 6z, and the correction amount is obtained corresponding to the rotating speed of the spindle (12) and stored in a storage device 13. In machining, the correction amount is read corresponding to the spindle speed, and a program command value is corrected to perform machining. Even when the cutting position of the tool is displaced due to high-speed rotation, the program command value is corrected to perform machining, so that high-accuracy ultraprecise machining can be achieved.
