摘要： A floating non-contact ultrasonic enhanced flexible sub-aperture polishing device and method are disclosed, an X-axis moving platform, a Y-axis moving platform, a Z-axis moving platform and a workpiece swinging platform in linkage control ensure normal lines of a tool and a workpiece are kept at an identical angle to realize sub-aperture processing; the ventilation main shaft acts air pressure on the ball spline's end portion to form an axial thrust to let the tool axially float; a dynamic balance among hydrodynamic pressure, air pressure and dynamic pressure is performed on the polishing liquid by rotation of the flexible tool; a tiny gap between the tool and workpiece is formed by elastic deformation of the flexible tool due to the dynamic pressure; a shearing force for removing materials is generated when the polishing liquid flows through the gap; a cavitation effect in the gap is formed by ultrasonic waves.

摘要： The invention relates to a method, a tool receptacle (13), and an apparatus for turning a face of a workpiece (2, 102) with a tool (3), wherein the workpiece (2, 102) is held in a workpiece receptacle (12) rotating about an axis of rotation (100) of a workpiece spindle, wherein, for producing and/or machining a workpiece contour having convex and/or concave portions on the face (20) that extend over defined angles of rotation, the tool (3) and the workpiece (2, 102) are moved back and forth relative to one another in an axial movement along the axis of rotation (100) of the workpiece spindle, said axis being synchronized with the rotational movement of the workpiece (2, 102), and wherein a blade (30) of the tool (3) is aligned at least in the cutting direction and/or transverse to the cutting direction opposite to the surface normals (N) of the workpiece contour to be produced and/or machined, in such a way that an effective clearance angle (α) and an effective cutting angle (γ) remain at least virtually constant opposite to the surface normals (N). The invention relates to a workpiece (2, 102) having a turned face.

摘要： Methods, apparatus and systems for polishing an optical component having an aspheric or freeform surface are described. In one example aspect, a polishing device includes a solid plate and a container coupled to the solid plate. The container encloses a non-Newtonian material that exhibits a solid-like and a fluid-like behavior based on a frequency of a stress applicable to the non-Newtonian material. The device also includes a layer of viscoelastic polymer adhered to the container to polish the optical component. The layer of viscoelastic polymer comprises one or more segments positioned according to a shape of the solid plate.

摘要： Provided is a local polishing technique suitable for corrective polishing. Press polishing is performed while supplying a polishing solution between a work and a work-polishing rotating tool locally pressed against the work, the polishing solution having abrasive grains composed of organic particles with an average particle size of 5 μm or more dispersed in a liquid. The rotating tool is made of an elastic material.

摘要： An optical element processing tool for grinding or polishing an optical element includes: a base plate including a fixing region having a predetermined curvature; and a plurality of grindstones each formed in a columnar body having a same initial height, one end surface of the columnar body having an initial shape molded into a first spherical shape conforming to a processing target spherical shape of the optical element, and the other end surface of the columnar body being fixed to the fixing region of the base plate. A grindstone deviant from a condition among the plurality of grindstones, which is the grindstone not meeting a condition determined by a processing tool diameter of the processing tool, includes an outer end portion cut out at least in parallel to a center axis of the base plate so as to meet the condition.

摘要： A lens manufacturing method including a holding step of holding a lens in a lens holding fixture, and a machining step of machining a surface to be machined in the held lens. A reverse surface of the surface to be machined is machined into a non-planar shape with a first surface shape error. A lens holding surface of the lens holding fixture is machined into the same shape as the non-planar shape with a second surface shape error smaller than the first surface shape error. In the holding step, the reverse surface is brought into surface contact with the holding surface in imitation of the holding surface to correct the shape of the lens such that the reverse surface runs along the holding surface. In the machining step, the surface to be machined is machined in a state where the correction has been made by the holding step.
