servo press

(OP)
Our business team is looking at using servo presses instead of pneumatics / hydraulics for an assembly operation. We feel that the this would elimunate the need for additional error-proofing (i.e. load monitoring, part presence, etc.)
What is the downside to use of these presses? What are the failure modes, mean time to repair, etc. compared to other methods?

RE: servo press

I have designed several servo presses. These were to replace an older hydraulic press design.

There are many positives of using a servo over hydraulics/pnuematics. But the negatives are cost and the mechanicals and controls are more complex. Depending on the design of the press, the stroke can be a limiting factor on a servo. And the maintenance stroke is often limited. And regards to maintenance, the servo requires much less than hydraulic.
