I can't divulge great details since we are building the first machine and we have competitors that did not get the business, but would like to grab it if possible. We will be core drilling steel reinforced concrete with the machine. The hole depths are only a few inches. It is a very specialized application. Not mining related at this point. The four spindles will be positioned via stepper motors and screws but the drill motors will be powered via hydraulics. Since the drilling process requires cooling water, it isn't possible to drill much below 32 degrees without big problems. I think that vibration and condensation will be the two big issues. The temperature range doesn't seem to be a big problem. The machine will be heavy so I think I can manage vibration. Condensation is the last element and I'm thinking that is going to require a sealed control panel and desiccant which is changed or dried out periodically. I just don't see anyway around it. Thanks for the link. Minibox or Logic Supply sells a water proof box made for ITX motherboards that looks a lot like their smaller PCs. The enclosure is about $800 or so. The problem I have is that I will probably have a 2'x3' control panel full of components that will need protection, not just a PC or a PC and a few I/O.
