（3）Milling Machining goes out seal face respectively in blank two side ends again.
（4）By the seal face clamping of blank on milling machine, then in the interior outer end of blank circular arc is milled out respectively, in the base of blank
Blade root tooth form is milled out on quasi- face respectively, the blade root tooth form on two datum levels is symmetrical.
（5）It will complete step（4）Blank, according to positive lozenge angle wire cutting a piece of one on interior outer end arc surface
The forward direction of piece moves root piece, then the plane that positive dynamic root piece two sides are cut into is milled to size, completes positive dynamic root piece
Processing.
（6）It will complete step（4）Blank, according to reversed lozenge angle wire cutting a piece of one on interior outer end arc surface
The reversed dynamic root piece of piece, then the plane that reversed dynamic root piece two sides are cut into is milled to size, complete reversed dynamic root piece
Processing.
It carries out being cut into several dynamic root pieces by the entire arcuation blank of first preparatory processing one, then by turned blank is completed,
It to saving material, reduces costs, and by processing tooth form blade root and interior outer end circular arc on an entire arcuation blank, one
Secondary clamping has just milled out the tooth form blade root of more than ten dynamic root pieces and interior outer end circular arc, the production and processing for improving dynamic root piece are imitated
Rate.
In step（1）Described in blank use 1Cr13 alloy material；With good corrosion resistance, machining property.
In step（2）Described in datum level between the depth of parallelism be not more than 0.03.
In step（4）The arc radius of middle inner arc surface is R311, and the arc radius of exterior arc surface is R380.
In step（4）Described in blade root tooth form using turn over processing method machine-shaping, i.e., first one end of blank benchmark
Blade root tooth form is milled out on face, overturns blank, then symmetrical blade root tooth form is milled out on the datum level of the other end of blank.
In step（5）,（6）Described in lozenge angle be 119 °, it is consistent with the water chestnut face angle degree of positive reaction blade so that
When assembling impeller, impeller surface is flawless.
The invention has the advantages that design is rationally, it is skillfully constructed, material saving is at low cost, and clamped one time has just milled out more than ten and moved
The tooth form blade root of root piece and interior outer end circular arc, improve the production and processing efficiency of dynamic root piece.
