The intensity size that will not influence this reamer is set, and increase cooling space can be more advantageous to, improves cooling and lubricating effect, in turn
Improve processing quality.
Preferably, the hard alloy based on deep hole machining squeezes reamer, and shank is flexibly connected with lathe.Due to existing hinge
Shank section generally uses staight shank, Morse taper shank, is inconvenient to dismantle after reamer installation, after being processed hole ream, reamer can only be from
Ream returns in hole, therefore reamer cutter tooth may damage ream hole, to reduce ream precision and by ream hole table
Face quality.
And the shank of the present apparatus is flexibly connected with lathe, and after completion of processing, lathe and shank are separated, at this point, cutting
Partially, calibrated section, neck and shank pass through processing hole, without backtracking, therefore will not make to the side in ream hole
At damage, ream precision further ensure that and by ream hole surface quality.
Preferably, the hard alloy based on deep hole machining squeezes reamer, along the direction of cutting tip to calibrated section, together
On the cross section of a cutting part point, the difference of diameter of diameter and cutting tip of circular cone land is identical.Such setting is squeezing
When processing, it can be more advantageous to accurate extruding, be more advantageous to raising processing quality.
The utility model compared with prior art, has the following advantages and benefits:
1, the utility model squeezes reamer based on the hard alloy of deep hole machining, and the present apparatus is by squeezing reamer to processed
Hole carries out extrusion process, and processed hole precision can achieve H4 grades, and roughness value can achieve Ra0.05 μm, can effectively improve
