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.
摘要翻译：一种用于机床的控制器，其能够通过执行校正，可以根据转速产生的主轴的位移，以高精度执行超精密加工。当主轴高速旋转时，由于主轴配合精度和重量平衡的影响，安装在主轴上的刀具的切割位置会发生变化。通过测量通过非接触式位移计连接到主轴上的工具的端部的X，Y和Z方向上的位移，以与主轴的转速相关的方式获得校正量，并存储在存储设备。在加工过程中，根据主轴的速度来读取校正量，并且根据使用由此读取的校正量校正的程序命令值执行加工。即使在高速旋转期间刀具的切割位置变化，根据修正的程序命令值进行加工。因此，可以高精度地进行超精密加工。

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.

摘要： A linear driving device that reduces a cogging force with a simple structure as opposed to a drive mechanism having an existing structure, deals with a plurality of cogging waveforms having different periods, and suppresses not only the cogging force but also pitching that is vertical oscillation. The device has a structure provided with a plurality of magnet arrays in which permanent magnets having different polarities are alternately and rectilinearly arranged in the same direction, and a plurality of coil modules having a plurality of teeth and slots fitted with armature coils. The arrangement distance between the coil modules disposed along the displacing direction of each of the magnet arrays equals the sum or remainder of the length corresponding to a half of any one of periods possessed by the cogging force generated when the coil modules move by one magnetic pole and an integer multiple of the length of a magnetic pole pair. The coil modules are connected to each other by a connecting member, and the connecting member makes relative motion along the magnet arrays.

摘要： A winding of a motor is formed by coiling a wire around a slotless stator core with combination of troidal coiling and array coiling. The toroidal coiling is carried out in a manner such that the wire is coiled without any intersecting turns in one direction for the formation of the winding as it is coiled rotating spirally. By this coiling method, the accuracy of the position of the winding in the direction tangent to the surface of the stator core can be improved. The array coiling is carried out in a manner such that the winding is formed in layers that are stacked on one another. By this coiling method, the accuracy of the position of the winding in the direction normal to the surface of the stator core can be improved. Thus, the overall thickness of the winding can be made uniform.

摘要： A temperature control system for a machine tool capable of quickly responding to an ambient temperature change. A mechanical section of the machine tool is surrounded by a machine cover. Gas of which temperature is controlled by a temperature controller is discharged from bearing portions of gas bearings in the mechanical section to a region surrounded by the machine cover through a pipe and a gas bearing channel. A branch pipe is provided for directly introducing a part of gas discharged from the temperature controller to a temperature sensor inside the machine cover. The temperature sensor measures the temperature of gas mixture obtained by mixing the gas introduced directly from the pipe with air inside the machine cover in a predetermined ratio. The result of measurement by the temperature sensor is fed back to the temperature controller to control the temperature of the gas supplied to the gas bearings.
