When machining middles or other prismatic parts, centering is a delicate and time-consuming operation. Whether the operation is carried out on a lathe or on a machining center, the problem remains the same: clamping the part with equal pressure on all its sides in order to ensure perfect centering. With a traditional collet the centering operation can become difficult if the X and Y dimensions of the part are not perfectly equal. In order to provide a solution to this recurrent problem (...)

A complete range for milling
The main activity of Meyrat SA is in the field of spindles for machine tools. The company offers a complete range of motorised milling spindles with a flanging diameter of 50mm (MMO-50). These spindles use the HSK cutting-tool clamping system and can reach very high levels of precision in terms of radial deviation measured on the tool tip. This technology also means the tool length can be measured outside the machine, thus providing gains in productivity as machine idle time is greatly (...)

Keeping the bar where it is…
The automotive industry is constantly raising the bar, creating a high workload for subcontractors in this field which means they really need to attack the material at speed. In some cases, this speed means the bar tends to actually move back, which obviously has a detrimental effect on machining. To solve this problem, there are numerous grooved or hatched grippers, however these can damage the material. So... Is there no solution? We met Alain Marchand, director of Swisscollet SA, who (...)
