      In CNC machines, Ball screw is used instead of lead screw. How about your machining facilities for ball screw ? Better you can order to a ball screw manufacturing company with your specification.

      If you drive your lead screw directly and you want 1 mm per step, you are going to need a lead screw with a pitch of 48mm, which would need to have a huge diameter! Why do you need 1 mm per step? Probably better to use more steps and appropriate gearing.....
