Silvestrini SA 1 ORBIT EL T5 — Turning gears – Positioners – Welding dericks & -pinchtables

The positioner SILVESTRINI Mod. SA 1 ORBIT EL T5nbsp; are composed by:
HEADSTOCK Section
The structure in rugged electro-welded steelwork, supporting a motorized (horizontal axis) rotation system.nbsp;
The rotation is given by a gear motor that, by means of a pinion, meshes with a large slewing bearing, to which is fixed the ORBIT Structure.

This sectionnbsp; is equipped with lateral precision guides to permit the ORBITnbsp; vertical lifting movement.nbsp;
The elevation is hydraulic, by means of hydraulic piston on which are inserted special clamping safety valves, that prevent the fall of the table, in case ofnbsp; accidental breakage ofnbsp; tubes.
On the horizontal axis is installed an electric rotating joint for the connexions with the Orbitnbsp; table (vertical axis). This permits the total axes free rotation.

MECHANICAL STRUCTURE ( ORBIT)
It Is constructed in rugged electro-weldednbsp; steelwork and holds a rotating table (motorized like the over mentioned headstock) that will support thу working pieces innbsp;
high accuracy.

A special bronze rotary earth connection (Silvestrini patent) transmits welding current.nbsp;
