    摘要： A multistage fine-hole machining device has lap stations for lapping an inner surface defining a through-hole of a workpiece. Each of the lap stations has a passing unit for passing wire through the through-hole of the workpiece, a supply unit for supplying a polishing material to the wire, and a sliding unit for effecting relative sliding movement between the workpiece and the wire while the wire is passed through the through-hole of the workpiece and is supplied with the polishing material to thereby lap the inner surface of the workpiece with the polishing material and enlarge the diameter of the through-hole. A transfer device successively transfers the workpiece to each of the lap stations to lap the inner surface of the workpiece at each of the lap stations during the lapping operation for successively enlarging the diameter of the through-hole to a preselected diameter.

    摘要： A method of manufacturing a ceramic part having a hollow portion and at least one hole extending through the ceramic part from the hollow portion to outside the ceramic part. The method includes the steps of molding a ceramic compact having the hollow portion, forming a hole in the ceramic compact, beveling an edge portion of the hole by passing a wire with a grindstone attached thereto into the hole from the hollow portion and then pulling a portion of the wire which has protruded from the hole while rotating the wire, and firing the ceramic compact.

    摘要： A method and apparatus for improving the performance of rimless spectacle lenses. An abrasive wire is provided for polishing bore holes which are drilled in lenses. The abrasive wire includes a wire substrate with abrasive particles embedded along its length. The wire and particles are dimensioned for threading through the bore hole and allowing space to perform a soft-filing operation. By polishing the micro cracks formed during drilling, propagation leading to lens failure which arises from spectacle use can be reduced.

    摘要： In a ceramic part having at least one small hole or both a hollow portion and small hole(s) which extends from the hollow portion to an outside, an edge portion of the small hole(s) is beveled. In a ceramic part having at least one small hole for a cooling mechanism through which a cooling medium is circulated, the surface roughness of an inner surface of the small hole is R.sub.max 7 .mu.m or below. Such a ceramic part having at least one small hole has no chipping or edge around the small hole(s) which can cause breakage at high temperatures and under high pressures, and is thus stronger than a conventional ceramic part. Such a ceramic part is suitable for use at a high temperature, for example, at 1000.degree. C. or above, and is particularly suitable as a gas turbine member, such as a turbine blade or a turbine nozzle of a gas turbine.
