Embodiment Construction
[0032] The processing method of the slender blind hole on the cylinder block of the 100 kilowatt high-voltage nuclear power steam turbine of the present invention adopts such as Figure 4 The positioning control tool shown in the figure can process a straight hole on the cylinder with an included angle of 20° to the horizontal plane and a 0° included angle to the vertical plane, and a straight hole with an included angle of 0° to the horizontal plane. 20° space angle hole with an included angle of 5° with the vertical plane at the same time;
[0033] The positioning control tooling includes a base 1, the base 1 has a slope 2, and a positioning block 3 is arranged at the bottom of the slope 2; a center hole 4 is arranged on the slope 2 at the center of gravity of the base 1 (the center hole 4 is the center of the positioning control tooling );
[0034] There is an angle of 20° between the slope 2 and the bottom surface of the base 1;
[0035] Processing method of the present ...
