BB5000 USED FOR TIGHT TOLERANCE AXLE REPLACEMENT ON THE ROCK ISLAND DAM DRAFT TUBE GATE

Knight Construction and Supply, Deer Park, WA performed the axle replacement on the Rock Island Dam draft tube gate for the Chelan PUD. This job required removing the 36 existing axles and wheels, line boring the existing holes, installing a new Stainless Steel bushing with .004” inference fit, and then boring the new bushing to size. The tolerances to meet the specifications were from +.002 to -.002. Knight Construction used the Climax BB5000 boring machine to perform this work. The boring machine worked great and customer service was great also. Knight Construction and Supply is a general contractor that preforms work on Hydro Electric Dams and various types of Mills. We have used the Climax boring machine and the Climax key way mill on other job with great success.
