| Abstract: | How to ensure the verticality between sixteen couple guide vane holes and their flange surfaces in head cover and bottom ring in taper guide vane apparatus is the main problem in machining the tubular unit(GZ003-WP-550) with 10MW manufactured by our works. Here we introduce the machining method of it as well as the construction and principle of automatic feed device, which controlls boring head to turn backward to the flange surfac(?)s with sixteen couple guide vane holes along diametral lines. it is a feasible machining method to boring the head cover along with the bottom ring for the guide vane apparatus of large bulb turbine and ensuring the verticality between guide vane holes and their flange surfaces. |
