Develop new processing technology or deburred technique, the Burr Problem produced when more effectively solving ABS hole machined becomes the technical problem that this area is badly in need of solving.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of processing technology of axle house connecting flange ABS hole, thoroughly solves the phenomenon of burr varus, and high degree reduces deburred difficulty, improving product cleannes quality.
The present invention solves the processing technology in the axle house connecting flange ABS hole that its technical problem adopts, and comprises the following steps:
A, heavy boring: adopt boring cutter heavy boring ABS hole;
B, chamfering: adopt rose reamer to carry out chamfering to ABS outer end of hole aperture;
C, anti-right boring: adopt reverse boring cutter right boring ABS hole, anti-thorax cutter is moved to ABS outer end of hole face by ABS hole inner face.
Further, before steps A, adopt milling cutter milling ABS outer end of hole face.
Further, planar disk milling cutter milling ABS outer end of hole face is adopted.
Further, described reverse boring cutter is with fine-adjusting unit.
Further, the boring cutter in steps A is through hole boring cutter.
Further, in step B, the angle of chamfering is 40 ° ~ 50 °.
Further, in step B, the length of chamfering is 1 ~ 2mm.
The invention has the beneficial effects as follows: effectively can solve Burr Problem by the cooperation of step B and step C, namely first chamfering is carried out to ABS outer end of hole aperture, then reverse boring cutter is adopted by ABS hole inner face to anti-right boring ABS hole, ABS outer end of hole face, step C adds the flanging burr produced man-hour and turns up to ABS outer end of hole face, because step B has carried out chamfering to ABS outer end of hole aperture, therefore, the burr turned up very easily is removed, and can not remain.Effectively can solve the intersecting lens place that burr in prior art remains in ABS hole circle cylinder and flange mesopore 22 face of cylinder, the not problem of easy-clear, not only can improve the cleannes of product, and reduces the labour intensity of workman, reduces production cost.
