January 2006 5 After an area was cut in the top of the liner with the flange facer, the piston- cleaning ring was installed and the head inserted in order to capture the ring. The high torque and versatility of the FF6000, led to a three-pass cut, bevel- ing, and radius cut operations in a very short amount time, enabling the team to machine three liners per shift. Now when the piston comes up, it scrapes the carbon off the top of the piston, elimi- nating the build-up problem. For this job and others, Power Tech relies on the Flange Facer 6000 for max- imum efficiency. It offers 550 ft. lbs. of torque at the cutter; a speed-enhancing radial feed of .076 - .813mm per revolution, and a swiveling head able to rotate 45 degrees in either direction. It also provides down-feed rates from .076 - .254 mm per revolution and a 76 mm diameter- turning bar to ensure a rigid tool plat- form. The engine maker's senior Service Engineer, in charge of quality control, said, "Typically, this type of work is done in a workshop, but a portable tool eliminated the need to dismantle the engine, saving a lot of time and money." An equally time-sensitive challenge was presented to L.A. Maritime Services, a company, which specializes in marine diesel engine repair and spe- cialty engineering services. One customer, experiencing cracks on the cylinder liners of one of its ship's diesel engines, commissioned the com- pany to discover the cause of the prob- lem, to repair the damage, and also offer a way to prevent it from reoccurring. L.A. Maritime's solution combined the expertise of the engine's manufacturer and Climax. Removing the liners would have been a time-consuming process and would seriously impact the customer's shipping schedule. Instead, L.A. Maritime rented Climax's Flange Facer 6000 and made the necessary repairs on-site. The process entailed removal of dam- aged material, which was caused from excessive heat. This not only eliminated existing cracks but also improved cooling of the cylinder liner to prevent new cracks from reappearing. The repair of eight cylinders on each of the customer's several ships is sched- uled to be an ongoing project, with one to three cylinders repaired each time a ship is in port. Although the Flange Facer 6000 is designed for versatility — L.A. Maritime uses the tool for placement of anti-polishing rings into cylinder liners, surface smoothing of engine block com- ponents, and repair of maritime cranes - reserving and renting the machine at the specific times it's needed has proven to be the most cost-effective option.
