IO Machines

The ETL 'IO Type Machines' are required when a higher accuracy sizing is required. The machines have a dual action cylinder which applies a separate and individually controlled force to each element of tooling, the inside expanding fingers and  the outside reducing jaws.  The machine and tooling are capable of calibrating, expanding, reducing and producing annular/emboss forms.

Ten operating sequences are provided by the thumbwheel, and understanding them will help you get the most out of the machine.  For example, a sizing operation which requires a close tolerance inside diameter choose a sequence in which the Outer Ram returns before the Inner Ram.  For critical Inner-with Expansion.: the sequence would be, the inside fingers would expand to the setting of the stop nut, then the outside jaws would close to the stop nut , or else close down to squeeze the outside of the tube onto the fingers (both should be set to occur at the same time.) After a barely visible delay the outside jaws should retract followed by the collapse of
the inside fingers.
