摘要： An eccentric facing unit wherein a tool driving shaft is concentrically disposed in a spindle for relative rotation with respect to the spindle. A tool-shaft supporting shaft is eccentrically disposed in a spindle and is connected with the tool driving shaft through a geared transmission so as to rotate at speed two times faster than that of the tool driving shaft. A tool shaft is eccentrically disposed in the tool-shaft supporting shaft in an eccentricity equal to that of the tool-shaft supporting shaft with respect to the spindle and is connected through an Oldham's shaft coupling with the tool driving shaft for integral rotation therewith.

摘要： A spindle capable of operation at 200,000 revolutions per minute (RPM) with a reciprocating shaft design to minimize the moving mass. The spindle has a ceramic spindle shaft to decrease the moving mass and increase the shaft stiffness for better dynamic stability. The spindle employs a built-in linear motor to provide direct drilling motion to move the shaft along the axis, and a permanent magnet DC brushless motor to rotate the spindle shaft. The linear motor is coupled to the shaft by a combination of an air bearing and a magnetic thrust bearing to reduce the size of the thrust area for better dynamic stability and reduction in stresses of material. A double gripping centrifugal chuck is mounted in the hollow ceramic shaft, and reduces drill bit runout.

摘要： A machine tool for at least triaxial machining of work pieces comprises a column of the type of a casing with side walls. In an interior space, provision is made for a work spindle which projects into a working area and which is connected via couplers and hinges to a driving skid that is displaceably guided on each side wall straight in a y direction. The driving skids are displaceably guided on two guides which are spaced from each other in the z direction. Provided between the guides are linear motors, a first part of which is mounted on the driving skid and a second part on the side wall.

摘要： The present invention relates to a method and a device in the chip-removing machining of a work-piece by means of a rotatable tool with a shaft arranged in a headstock. The tool is displaceable in an axial direction both towards and away from the work-piece, and in a plane substantially perpendicular to the arbor. Arranged around a machining point is an enclosure. The enclosure has a first opening that is designed to press against the work-piece around the point to be or being machined. A second opening in the enclosure is made in a wall substantially perpendicular to the shaft. This opening is designed, during machining, to press against a plane plate arranged behind the tool and around the headstock, substantially perpendicular to the arbor, so that during machining there is a substantially enclosed space in the area around the tool and the machining point. The device includes a line for delivering cutting fluid to the machining point. The enclosure can be provided with an outlet opening through which chips that are removed are evacuated from the enclosure by the delivered cutting fluid.
