The invention discloses a novel multi-station disc type buffing machine. The novel multi-station disc type buffing machine comprises a rotary table assembly. Clamp devices of multiple stations are evenly arranged on the rotary table assembly at equal angles in the circumferential direction. A space is left in the portion, corresponding to the clamp device of one station, of the periphery of the rotary table assembly to form a loading and unloading station. The portion, corresponding to each clamp device of the remaining stations, of the periphery of the rotary table assembly is provided with a buffing device. Each clamp device comprises multiple linked clamp assemblies. Each buffing device comprises a three-direction sliding assembly and a buffing machine head assembly arranged on the three-dimension sliding assembly. Each buffing machine head assembly comprises multiple machine head structures corresponding to the clamp assemblies one to one. The rough polishing procedure and the fine polishing procedure can be finished on one machine, the fine polishing requirements of workpieces of different hook face shapes and sizes are met, production efficiency is greatly improved, it is guaranteed that the polishing quality of the workpieces is stable and consistent, production efficiency is greatly improved, and economic benefits are greatly increased.

Novel multi-station disc type buffing machine

A polishing apparatus for semiconductor wafers includes an index table with multiple wafer positions, with different surface treatment arrangements for each position. With each index motion of the table, the table is sequentially loaded and unloaded while wafers carried at the remaining stations of the index table are moved for a subsequent surface treatment step. Progress of the surface treatment at each position is monitored and, optionally, subsequent surface treatment steps may be modified to achieve a desired final condition of the substrate being processed.

Vorrichtung und Verfahren zur Oberflächenbehandlung von Bauteilen

A machine is adapted to carry outpolishing/finishing action, using a magnetic abrasive medium, on a shafted gear (5) of the type used in hydraulic gear pumps and having a pair of stub shafts projecting one on either side of a gear wheel. The machine comprises a rotatable work table (1) having on its periphery clamping devices (2) each comprising a bracket fixed to the table (1) and supporting upper and lower holders which engage with the ends of the stub shafts to hold the shafted gear (5) in position to be worked on. A plurality of working stations (4, 6, 7, 8) are spaced around the periphery of the work table (1) and the work table (1) is rotatable incrementally to advance the clamping devices (2) from one station to another to enable the series of working actions to be carried out. A driving device anociated with each clamping device (2) includes a drive gear driven by a motor and resiliantly engaged with the shafted gear (5) when the latter is undergoing treatment at one of the working stations. At least one of the working stations (4) is arranged to carry out polishing action on the stub shafts of the shafted gear (5) and comprises pairs of blades which embrace respective stub shafts therebetween, means for magnetising the blades and means for feeding magnetic abrasive medium into the spaces between the blades and the stub shafts.
