Law/Patents - Mechanics / Mech Engineering / draw rod of a machine tool
English term or phrase: arbor
In metalworking and/or testing operations, particularly gear manufacturing and testing, where a workpiece
is machined, equipment of some type is necessary to hold the workpiece in position in a machine tool so the
machining and/or testing process can be successfully carried out. This type of equipment is known as
"workholding" equipment. In the production of toothed articles, such as gears, workholding equipment can be
generally categorized as two types, chucks and arbor.

Arbors grip a workpiece by expanding a collet into contact with a surface of the workpiece. As an example,
a bevel ring gear is placed on an arbor and the collet is expanded until contact of sufficient force is established
with the surface of the bore of the ring gear to hold the ring gear in position during machining

In either chucks or arbors, the force necessary to contract or expand the collet mechanism is provided
by a draw rod in the machine tool. The draw rod is advanced and/or retracted usually via a hydraulically operated
piston or sleeve attached to an end of the draw rod opposite the end communicating with the workholding
mechanism. In general, movement of the draw rod in the axial direction of the chuck or arbor usually causes opposed
angled surfaces of components within the workholding equipment to slide relative to one another
resulting in inward (contracting) or outward (expanding) movement of the collet as is necessary to grip or release
a respective workpiece or component part thereof.

albero (del mandrino)


Explanation:
The arbor. An arbor is the spindle to which the chuck is fastened. The arbor can be machined onto the end of a drill spindle or it can be a separate small part that can be removed from the drill.

la testa motrice: supporta l’albero del mandrino alla cui estremità destra è fissato il mandrino autocentrante sul quale viene montato il pezzo. Contiene gli organi motori, i cambi di velocità per modificare i giri dell’albero del mandrino e anche i cambi per far variare la velocità di avanzamento del carrello portautensili.
