Abstract: The pallet includes one or more supporting faces, each of which is provided with an anchorage system for equipping the clamping fixture of a rough piece to be machined with machine tools. Each supporting face has one or more anchorage members for components of said clamping fixture. Each anchorage members may be adjusted as to height and as to angular orientation and is connected with a supply of fluid.Said adjustment is carried out by screwing and unscrewing said anchorage members in corresponding appropriately threaded holes in the supporting faces of the pallet.

Abstract: A machine is accomplished comprising two pairs of operating heads in which each pair includes two identical operating heads essentially opposite to each other equipped with chucks rotating on horizontal axes having at one end a conical housing for receiving a tool.Each head can be moved longitudinally and vertically and the corresponding conical housing faces a central cavity.A machining tool or a clamping tool for holding the part to be machined can be inserted into each housing, so that one or two opposite chucks support the part while it is machined by the tool or by the tools inserted into one or more of the remaining chucks.
