Abstract

PURPOSE: To shorten a repairing period by setting potary rarts to be machine- processed to a regular installing fabrication state and machine-processing the rotary ports, revolving and driving the parts in hydrodynamics way.
CONSTITUTION: In order to repair a main bearing 12 and a main shaft water- sealing apparatus 13 on which abrasion and cracks are generated due to longtime usage, an inlet valve 7 is wholly opened, and a movable guiding vane 9 is wholly closed or opened a little, and the pressurized water in a casing 8 is introduced into a runner 1 to revolve rotary parts, and a revolution speed necessary for machine processing is maintained. Inertial revolution between the highest and the lowest revolution capable of cutting processing is repeated to perform cutting. An edge tool 19 for processing a main shaft runner 15 is fitted on a top cover 14 by a tool rest 18 a tool rest support 17, and when a main shaft 2 which contacts the bearing 12 is processed, the main shaft is supported by a temporary bearing, and cutting processing is carried out
