Abstract

PURPOSE: To grind the three dimensional curved surface of work intermittently and accurately, allowing to rotate and revolve the tool on the virtual center line of main shaft, in the grinding equipment to grind the three diemsnional curved surface of water-turbine runner.
CONSTITUTION: When grinding the surface 20a of work 20, main shaft 5 is turned, at the same time, bracket 7 with the shaft in a unit is turned keeping balance by weight 6. Spindle 10 inserted into bracket 7 with inclination is rotated and revolved due to its revolution, tool 18 integrated with spindle 10 grinds the surface of work 20 intermittently. That is, spindle 10 rotates by a small transmission shaft 16 integrated with it, revolving around vertual center line 11 of main shaft 5, the surface 20a of work 20 is ground with tool 18.
