摘要： A fine adjustment thread assembly couples a first part and a second part to each other while keeping the first part and the second part spaced apart, adjusts the distance between the first part and the second part, and detects a load applied to the second part. The assembly includes first external threads that can be brought into threaded engagement with first internal threads formed in the first part, second external threads that are axially spaced from the first external threads, that have a thread pitch different from that of the first internal thread, and that can be brought into threaded engagement with second internal threads formed in the second part. A joint portion between the first external threads and the second external threads houses a load sensor under a compressive load.

摘要： A method of grinding a workpiece includes a holding step of holding the workpiece on a flat holding surface of a holding table and a grinding step of rotating a grinding wheel to turn grindstones along an annular track while rotating the holding table, and bringing the grindstones into grinding contact with an upper surface of the workpiece to thereby grind the workpiece. The grinding step includes the step of bringing the grindstones into grinding contact with the upper surface of the workpiece in a state where the annular track is closest to the holding surface in an area between a point above a center of the holding surface and a point above an outer circumferential end of the holding surface.

摘要： A device for grinding a continuously cast product, in particular a slab (11), a billet or a block. The Device has at least one rotationally operated abrasive disk (10), which is attached to a grinding head (15). At least one high-pressure air nozzle (14) is arranged on the grinding head (15). The high-pressure air nozzle blows the continuously cast product free of particles adhering to or lying on the continuously cast product prior to grinding.

摘要： A polishing device configured to polish a glass substrate is disclosed, including a polishing wheel fixedly arranged, a cooling pipe, and a movable platform. The polishing wheel has an outer peripheral polishing surface, the glass substrate is placed on the platform and is driven by the platform to move so as to make the outer peripheral polishing surface polish the predetermined polishing surface of the glass substrate; the polishing wheel further has a chamber, and the cooling pipe containing a coolant is disposed in the chamber to decrease a temperature of the chamber and then to make temperatures of the outer peripheral polishing surface and the predetermined polishing surface during polishing is lower than a preset temperature. The disclosure solves the problem of high polishing temperature of the polishing wheel and the glass substrate, thereby enhancing the service life of the polishing wheel and the yield of the glass substrate.

摘要： The present invention relates to a retainer ring structure for a CMP apparatus and a method for manufacturing the same. The retainer ring structure may include screws for fixing the retainer ring structure mounted on a polishing head during a CMP process, the screw being made of a high-strength metallic material, and the method for manufacturing the retainer ring structure may be simplified. Thus, a coupling force with the polishing head may be increased to reduce a defect rate, and the process may be simplified to reduce an operation time and a manufacturing cost, thereby increasing merchantability.

摘要： A device for polishing of a multi-surface workpiece is described. The device includes a base and a vertical motion platform that moves along two support rods, which carries a motor that drives a rotating shaft. The support rods extend from said base. A polishing tool is attached to the motor shaft. The workpiece being polished is placed on a linear motion stage during the polishing process.

摘要： A complex geographical edge finishing system includes a fixture that holds an external part having a complex three-dimensional edge, a track disposed around the fixture and surrounding the edge of the part held in the fixture, and one or more finishing apparatuses that can sand, polish, buff, paint and/or apply coatings to the complex three-dimensional edge. The finishing apparatuses move about the track such that the three-dimensional edge of the part can be polished. The path of the track can substantially match, mimic or otherwise correspond to the path of the three-dimensional edge, such that special requirements for the finishing apparatuses are not required.
