The degree of depth of root, therefore cause the interchangeablity made bad, it is the most all end tooth and the impeller of axle
End tooth individually manufactures, and could meet requirement, be i.e. after axle head tooth is probably carried out (typically can differ to
About 0.3-0.8mm, has that time difference 1mm is many just cannot be saved), then manufacture with the end tooth of impeller, join
Unifying, overall length difference is how poor few, is all compensated by the end tooth of milling impeller end.
The method that manufactures of existing main shaft and impeller end-tooth is: first carry out main shaft, and main shaft end tooth is deep
Till degree substantially accomplishes size, then when doing impeller, manufacture the height overall of axle and impeller with the height of impeller.

Main shaft and impeller is allowed individually to manufacture, it is impossible to disposably to produce in batches；2, to manufacture production cost higher for single-piece,
Can not effectively control cost；3, production efficiency is relatively low；4, interchangeability of parts is poor, can not at all
Exchange；5, single part measures the technology requirement that at all can not accurately meet length dimension；6, certain journey
The delay of manufacturing schedule, impeller and axle is caused individually not to carry out according to the manufacturing schedule of oneself on degree, must
Must manufacture；7, the most a certain part goes wrong, and has an immense impact on to the production producing another part is supporting；
8, the facewidth of end-tooth also cannot accurately be measured；9, traditional detection method cannot accurately detect height of teeth root
And height of teeth top；10, tradition cubing inconvenience is deposited and is managed, and has wedge, pole, contrate gear etc.
Part more (select from elder sister Wang you sample sent out to me)；11, several parts of tradition cubing scatter,
It not an entirety, pretty troublesome during use；12, several single parts are needed to coordinate due to tradition cubing
Location is detected, and the location of each part and placement can exist error, cause accuracy of detection to decline, very
To inaccurate；13, tradition cubing divides a few step to operate, and there is complex operation step；14, tradition cubing is deposited
In the limitation of the scope of application, even measuring defect, such as impeller, two broad in the middle is little just cannot be measured.
