| 20140199922 | Drag and/or dip finishing machine for the surface machining of workpieces by means of grinding and/or polishing granules in the presence of a liquid machining agent - A drag and/or dip finishing machine has at least one workpiece holder for the releasable fastening of the workpieces to be machined and a container, disposed beneath the workpiece holder, for accommodating the grinding and/or polishing granules, wherein the workpiece holder and the container are movable relative to each other in that at least the container is rotationally driven. The container has a chamber, which extends around the whole of the periphery thereof and is fluidically connected to the inside, accommodating the grinding and/or polishing granules, of the container, at least on a lower portion thereof, the chamber being equipped with a liquid discharge unit in order to be able to discharge the machining agent from the chamber in the event of an excess of machining agent in the container. | 07-17-2014 |
| 451106000 | Rotary work holder | 1 |
| 20140199923 | Apparatus for surface finishing workpieces and chucking device of an apparatus of this kind - An apparatus for surface finishing workpieces has a workpiece holder, on which a chucking device for releasably fixing the workpieces to be machined is secured, and a container arranged underneath the workpiece holder in order to receive grinding and/or polishing granules, which can be moved relative to the workpiece holder. A chucking device has a chuck, which is designed for at least partially positive holding of the workpiece for conjoint rotation. The chucking device furthermore has a vacuum duct, which can be connected to a vacuum generator and which opens into the chuck in order to hold the workpiece in such a way that it is fixed axially by the application of a vacuum to the vacuum duct. The chuck of the chucking device is arranged on an adapter piece, which can be fixed releasably on a supporting part of the chucking device. | 07-17-2014 |
| 451108000 | Reciprocating scouring tool | 1 |
| 20120149285 | Golf Ball Deburring Apparatus - A structure for deburring a ball is provided. The structure includes an arm, a gear structure for changing the effective length of the arm, and a cam structure for changing the effective angular position of the arm. A finger having an abrasive surface reciprocates on the arm. A ball is placed in a rotating holder and positioned in effective position for the abrasive surface to contact and remove at least one burr on the ball. | 06-14-2012 |
| 451109000 | Rotary cylindrical scouring tool | 1 |
| 20140127979 | POLISHING DEVICE - A polishing device is disclosed. The polishing device includes a load seat and two polishing mechanisms mounted on the load seat. Each polishing mechanism includes a driving member and a polishing member driven by the driving member. The two polishing members of the two polishing mechanisms are oppositely received in the receiving space, and oppositely rotatable driven by the corresponding driving member. The polishing members are rotated oppositely, such that the new burs generated by one of the polishing members can be removed by other one of the polishing members at the same time. | 05-08-2014 |
