The watch industry is profiting to an increasing extent from the trend towards status symbols. Through increasing demand, the necessity for manufacturing faster is also increasing without having to compromise on the quality.
These requirements for more efficient and faster machining possibilities require clamping solutions that are perfectly matched to the watch industry. With the new plate chuck of the “micro technology” series, Röhm makes it possible for the first time to machine both sides of plates with one clamping operation. So far, plates have been machined using two clamping operations: first the top side and then – after reclamping – the bottom side. This reclamping operation takes not only valuable time, but it also introduces a loss of accuracy.
To machine on both sides in one clamping
The cumbersome way of machining plates caused a great deal of unrest amongst the employees of Switzerland’s Röhm Spanntechnik AG. They wanted to offer Swiss watchmakers an efficient alternative that did not cause the machining accuracy to deteriorate. Quite the opposite: The new chuck was to be even more accurate. Hence, an ingenious solution was found together with the German parent plant of the clamping technology specialist with the involvement of well-known watch manufacturers: a chuck that for the first time makes it possible to machine plates on both sides with one clamping operation.
To simply change side
The patented innovation clamps the plate on a console and the first side is machined. Then, the chuck is swivelled by 180° on the machine (e.g. by a divider). During the automatic swivelling operation, the workpiece support also swings to the other side of the plate. This ensures a secure support for the plate on both sides, and overpressure is prevented. Now, the second side of the plate can be machined reliably and without any loss of accuracy.
