Processing machine has reduction gear converting rotary or pivotal movement of at least one drive shaft about longitudinal axis into smaller processing head holder rotary or pivotal movement

摘要

The machine has three rod-shaped drive shafts (5), each mounted by joints such as gymbal joints, each driven in translation and rotation and all commonly bearing a holder (4) for a processing head at one end, to which they are connected via a joint. At least one drive shaft has a reduction gear (6) that converts a rotary or pivotal movement of the drive shaft about is longitudinal axis into a smaller rotary or pivotal movement of the holder.
