The processing of connecting rod crank pin end through hole is carried out from digital-control boring-milling machine generally, process tool selects shallow hole drilling.Due to
The length of connecting rod crank pin end through hole its length for its aperture size is longer, the hole depth and aperture ratio of the general through hole
More than 5, in addition as clamping workpiece rigidity and lathe are rigidly poor, therefore, in order to ensure the crudy of workpiece, generally require
Using multi-step process such as brill, expansion, borings, as the hole is deeper, depth and diameter ratio is more than 5, when processing using common boring bar, meeting
As poor rigidity produces significant shock, so as to affect the roughness and positional precision in hole.In order to reduce vibration, on the one hand can take
Each processing capacity is reduced, increases processing number of times；On the other hand shockproof boring bar can be used instead, to increase processing capacity, reduces processing number of times.
A through hole is machined using digital-control boring-milling machine needs 5 hours or so.Therefore, this processing method is not only time-consuming, laborious,
And have an effect on production efficiency.And due to from shockproof boring bar, also add production cost.
