Multispindle head for working composite materials such as carbon.

摘要

The machining head according to the invention makes it possible to drill a multitude of evenly-spaced holes on a component of large surface-area made from composite material such as carbon. It is equipped with electrical spindles (5) rotating at high speed (forty thousand revolutions per minute) cooled by a circulation of oil. Means for sucking up the dust due to the machining are provided around the drill bits (7). Means (20) for holding the workpiece (11) are provided to prevent the workpiece from vibrating under the high rotational speed of the drill bits (7). Application to the perforation of the acoustic skins of jet engines.
