Pipe Boring

This customer had a German boring machine designed to bore holes in "pup" joint sized bar stock but the Two German regenerative drives arrived without schematics. When the first drive developed problems in the circuit boards, which would have required many hours of repair time to troubleshoot, we were asked for another option. The Control Techniques Mentor II regenerative DC drive was our choice for replacement. As soon as the first drive was replaced and the customer saw how much better the machine ran on the new drive, they asked us to replace both drives. These drives have been running since 1995 without problems.
