    摘要: A polishing assembly and method for polishing optical cables, the polishing assembly having a platform configured to receive a polishing film and configured to rotate according to a dual orbital motion; a force gauge functionally coupled to the platform and configured to measure downward force applied against the platform; a mounting fixture configured to mount a plurality of optical cables; and a movable arm configured to move the mounting fixture downwards to press mounted cables against the polishing film, upwards to pull the mounted cables away from the polishing film, and to rotate circularly along a continuous circular path. The optical cables are pressed against the rotating polishing film while simultaneously monitoring the downward force applied against the platform so that downward force can be maintained within a prescribed tolerance throughout the polishing process.

    摘要: 一种大尺寸单晶金刚石的磨削方法,利用大尺寸单晶金刚石的碳原子和活性磨料在特定的磨削条件下发生化学反应生成碳化物,再以硬质磨料去除生成的碳化物,实现高效高质量磨削金刚石表面。磨削液为去离子水,对环境无污染且磨削转速远低于动摩擦加工的要求。与传统的金刚石石墨化去除方式不同,能够得到表面粗糙度更低、裂纹更少、沟槽更浅的金刚石表面,可降低加工成本。

    摘要: [PROBLEMS] To provide an electron beam assisted EEM method that can realize ultraprecision machining of workpieces, including glass ceramic materials, in which at least two component materials different from each other in machining speed in a machining process are present in a refined mixed state and the surface state is not even, to a surface roughness of 0.2 to 0.05 nm RMS. [MEANS FOR SOLVING PROBLEMS] The EEM method comprises a working process in which a workpiece and chemically reactive fine particles are allowed to flow along the working face to remove atoms on the working face chemically bonded to the fine particles together with the fine particles through chemical interaction between the fine particles and the working face interface. The workpiece comprises at least two component materials present in a refined mixed state and different from each other in machining speed in the machining process. After the exposure of the workpiece in its working face to an electron beam to conduct modification so that the machining speed of the surface layer part in the working face is substantially even, ultraprecision smoothening is carried out by working process.

    摘要: A polishing apparatus for an optical fiber connector (10) that includes an optical fiber ferrule (14) and a connector housing (30), comprises a polishing puck (110) having an aperture (113) to permit passage of the ferrule there­through and a mount (114) to hold the connector housing at a predetermined angle. The polishing apparatus further includes a stabilizer (120) having a first portion mountable on the polishing puck to provide a grip separate from the connector housing. The polishing apparatus further includes a weighting device (130), at least a portion of which is disposed in the stabilizer, to provide a direct force on the connector housing, substantially independent from the stabilizer. The polishing apparatus provides a hand-polishing tool that controls the force and tilt placed on a terminated optical fiber connector during the polishing process, thereby providing more repeatable polished ferrules with respect to ferrule geometry such as ferrule radius of curvature (ROC), apex offset, and fiber height.

    摘要: Apparatus for cutting an industrial-size roll of paper or other sheet material into two or more rolls. The apparatus includes a circular saw with a radius large enough to cut through such a roll in a single cut, leaving press-ready rolls that require no finish-trimming on the ends. The saw blade is mounted in a saw frame that travels along a carriage and positions the blade at any desired cutting position on the roll. The apparatus includes a support bed and load-bearing arms for supporting the weight of a large roll and keeping it in position during the cutting operation. Load/unload tables and a system of kicking cylinders guide the roll onto and off of the support bed. The saw frame is a tower that positions the saw blade above the roll at the desired cutting position, or a floor frame that positions the saw along side or beneath the roll at the desired cutting position. The apparatus further includes a finishing station for sanding the ends of cut rolls.
