The trade-off in precision workholding with a hydraulic device, especially in the case of higher volume work, is that the hydraulic sleeve or clamping surface is, in most cases, integral to the device itself. This means that if the sleeve wears or develops a leak, then the majority of, if not the entire workholding device, needs to be replaced.

At a shop where I "work" occasionally they have to grind some 300 series stainless Charpy test sections that are supplied to them as very rough bandsaw-cut weld sections. Holding them to grind to specified size and shape after initial machining has been challenging. I think using some version of this clamping device may make that process easier.
