Abstract:
A neutron lens component processing apparatus comprising:a rotating table that holds a flat neutron lens component comprised of a substance with a refractive index of less than 1 for a neutron beam; a circular-disk type of metal-bonded grinding wheel comprised of one tapering surface or a plurality of tapering surfaces on the outer periphery thereof; a grinding wheel driving device that drives the grinding wheel to rotate around the axis thereof and moves the grinding wheel relative to the rotating table; an electrode comprised of a surface close to the single tapering surface or plurality of tapering surfaces of the grinding wheel; a power source that applies an electrolytic voltage between the grinding wheel and the electrode, and a grinding fluid feeder that supplies a conducting grinding fluid between the grinding wheel and the electrode, wherein the angle made by the single tapering surface or plurality of tapering surfaces is formed with a more acute angle than the angle of a V-shaped groove formed on the surface of the neutron lens component, the grinding wheel driving device positions the axis of the grinding wheel at an oblique angle to the axis of rotation of the neutron lens component, and the oblique angle can be slightly varied at that position.
