The wall thickness difference in the whole machined length is controlled in 0.02-0.10. The cutter for deep holes machining is long cutter bar of hard alloy and in the length/diameter ratio of 10-20. The deep hole machining technology of the present invention is advanced.
Description
Technical field:
The present invention relates to Machining Technology, a kind of deep hole processing method and dedicated tool thereof are provided especially.
Background technology:
In mechanical skilled worker's technology, deep hole machining is big technological difficulties all the time, and this type of technology receives much concern always.In deep hole machining, require to reach very high hole machining accuracy sometimes; For hollow Machining of Shaft-type Parts, main processing difficulties problem is exactly the control to hollow shaft wall thickness difference value.
Traditional deep hole machining moulding process is: boring, reaming, slightly cut with scissors the auger face, slightly cut with scissors the conelet face, finish ream the auger face, finish ream the conelet face, boring microcephaly uropore.Deep hole processing is everlasting and is carried out (referring to accompanying drawing 7) on the deep hole drilling machine, and drilling rod 8 helps the location by supplemental support 9, and each section deep hole, profile sectional forming are easy to cause the benchmark position error bigger than normal like this, and are easy to generate not coincidence error of each section inner hole centreline.Past adopts floating reamer under the uneven situation of ream surplus when thick fraising, and the unsteady cutter head secundly cutting of cutter is easy to generate the endoporus shift phenomenon, and this also can't repair when finish reaming.
In the deep hole machining process of prior art, deep hole (especially slenderness ratio surpass 10 or the degree of depth surpass the deep hole of 800mm) the wall thickness difference can only be controlled at about 0.10, internal control part wall thickness difference also only can reach 0.08 in the operation.Simultaneously, the coaxiality error in hole also is difficult to guarantee degree of precision.If requiring the wall thickness difference is still to continue to use traditional processing method under 0.05 the situation, the wall thickness difference qualification rate of processing back part is extremely low, and in whole deep hole profile, the inner surface axiality of the inner surface of aperture and macropore mistake error is bigger, causes the wall thickness difference overproof.After the past people often adopt and look for hole bigger than normal theoretical centerline to make it and aperture is consistent, process big internal surface of hole and guarantee and the requirement of aperture inner surface axiality; Then, repair internal hole reference and each surface of cylindrical, to guarantee the requirement of hollow shaft wall thickness difference.This method, it is very complicated to repair the processing process of getting up, and randomness is bigger, and some local sizes and technical conditions are not easy control very much.
Under to coaxiality error or the exigent situation of wall thickness difference, deep hole machining has become a technical barrier that urgency is to be solved.If we carry out deep hole boring processing, owing to be subjected to the restriction of hollow shaft structure, effect is still undesirable.Adopt original structural steel knife bar then not satisfy the structural requirement of hollow shaft and the requirement of processing rigidity.
