A wafer chuck, aye? That makes sense! I was trying to figure out what this circular object was, but you just happened to answer my question! Everything seems to be well in order. When do you plan on creating a prototype model for the drawing? Actually, I wouldn't mind seeing some of your process (drawing, base, fully rendered design). Perhaps it's a request that can be filled eventually?
Actually, the prototype's already been built. It's an expensive one, given the processes put into it (EDM, gun drilling, alodine, gold plating, etc) The drawing you see here is part of an assembly that is currently patent pending. Once the patent's approved, I'll post the renders in this forum.
