Our shop is looking for a new/newish big bore lathe with live tooling and possibly y axis milling capabilities. 32ish inch air chuck, 13ish spindle bore and 120ish z length. We will need a steady rest or two as well. The top 3 choices are a mazak quick turn or slant turn 550my, doosan 800l and a hwacheon something or other. Anyone have any suggestions? We are located in Alberta Canada and do a lot of small batch machining/repair work of oilfield components. Big API threads are very common in our shop and we also do a lot of deep boring with devibe bars. Any information on brands or opinions on live tooling with or without y axis capabilities would be appreciated.
