Abstract: A rocker polishing apparatus for full-aperture deterministic polishing of a planar part includes a control system, a substrate, a lifting plate, a polishing module and a measuring module. The polishing module and the measuring module are arranged on the substrate. The lifting plate is arranged between the polishing module and the measuring module. The polishing module includes a rocker mechanism, a polishing pad surface dressing mechanism, a polishing pad surface profile measuring apparatus and a continuous polishing pad mechanism. The apparatus allows the material removal rate distribution of the planar part and the surface profile of the planar part be in the normalized mirror symmetry relationship by controlling the material removal rate distribution on the surface of the planar part, thereby implementing the deterministic polishing of the planar part and ensuring the efficient convergence of the surface profile of the planar part in the polishing process.

Abstract: A sealing portion on a lower end of a cover portion of a spindle cover has an upper side surface and a lower side surface that are inclined toward an outer circumferential surface of a spindle. A larger-diameter disk and the outer circumferential surface of the spindle define therebetween a second gap that is narrower than a first gap defined between the spindle and the cover portion. The second gap is effective to prevent a processing waste liquid from entering between the spindle and the spindle cover to prevent a solid waste contained in the processing waste liquid from sticking to the spindle. The spindle is thus prevented from becoming less liable to rotate smoothly due to solid waste deposits.

Respective first and second workpiece spindles are each capable of holding and rotating a workpiece and are vertically displaceable on the first and second carriages. Respective first and second grinders on the frame carry respective first and second grinding wheels and are oriented to engage and machine workpieces held and rotated by the workpiece spindles. One of the grinders is movable horizontal or vertically on the frame.

Abstract: A spindle unit for a machine tool for fine-machining workpieces having groove-shaped profiles, has a rotatably mounted spindle shaft (2). The spindle shaft is subdivided in the axial direction (AR), one behind the other, into a fastening portion (A) for fastening a tool (4) or a workpiece to be machined, a first bearing portion (B), a force transmission portion (C), and a second bearing portion (D). A drive unit (5) serves to drive the spindle shaft by way of force transmission onto the force transmission portion. A first and a second bearing point (13, 14) are designed to bear the spindle shaft in the first bearing portion, and a third bearing point (15) serves to mount the spindle shaft on the second bearing portion. The first and the second bearing points each have one or more hydrostatic bearings. The third bearing point has one or more hydrostatic and/or hydrodynamic bearings.

Abstract: In a thread grinder which grinds a thread grove on an inner surface of a workpiece while a rotation axis of a grinding wheel shaft is inclined with respect to an axis of a main shaft, a centering master which has a cylindrical outer surface is mounted to the main shaft. A measuring unit including two measuring instruments such that probes can contact two edges of a grinding wheel is mounted to the centering master. The origins of the measuring instruments are set by the probes contacting the cylindrical outer surface of the centering master. The measuring unit is moved in the axial direction of the centering master to bring the probes of the two measuring instruments into contact with the edges of the grinding wheel, respectively. The position of the grinding wheel shaft is adjusted such that measured values obtained by measuring instruments become same.
