Hi Thomas,
Does the item being worked on need to be locked in a very rigid position, like in the GRS devices or can it be hand held in a ring clamp? The person suggested the item must be very rigid for the pneumatics to work with out problems.
I’d suggest that the more rigid the piece being worked on can be
help the better, regardless of whether it’s being manipulated by
machine or by hand.
If the piece isn’t rigid, any movement reduces the effectiveness at
the point of contact between the tool & the work. The piece needs to
be stationary for the tool to make an effective mark. Any movement
of the piece is just lost motion. Maybe all that lost motion
contributes to the wear & tear on the wrists, fingers & arms that
causes our aches & pains.
