Windsor Airmotive, a division of Barnes Aerospace, recently enhanced its in-house repair capacity with the installation of a new "HOMMA" CNC vertical-turning lathe that is equipped with state-of-the-art computer hardware and software. The HOMMA CNC lathe's cutting capacity exceeds 78 inches in diameter and is capable of handling work pieces up to 63 inches in height, making it desirable for many repair programs on high-bypass engine cases. The company is currently using this new lathe to machine the extended flange replacement forging for the Pratt & Whitney JT9D-7R4 low-pressure turbine case. Airmotive further reported that repairs on other engine components belonging to Rolls-Royce, General Electric, and Pratt & Whitney will be performed using the new system. Frank Bokulich
