The form of 1mm less than tolerancepublic errand requirement, the 5mm of mural thick ≥ of bolt aperture and appearance, oil duct, assemble the requirement of intensity in order to make sure sealed effect mixes oil path. According to craft arrangement wood path is underlined is undertake after mill is planar, benchwork need is put according to casting oil duct already A of datum plane of mill plane lay off and B. It is with body of this a powerful person here exemple introduce a kind to underline a method handily to everybody. Can be the treatment with proper lay off of follow-up working procedure to assure this line working procedure fiducial and referenced line, the design measure that we use the system of a powerful person of organic glass basis with large 5mm especially is the same as scale 1: 1 make underline example, aperture of appearance, oil duct, bolt and pin Kong Jun by line out of machining center of numerical control vertical exact position, its deepness is 0.
5mm, width is 0.
2mm, after using Tu Gong of red lead pink with respect to make it. If pursue,2 are shown. When using, should underline this only example aims each oil duct, at the same time give attention to two or morethings the 5mm(of mural thick ≥ of each aperture is visual) , delimit next the datum line of face of A, B can. Through two batches of spare partses (80) try application, discovery not only the line of lay off satisfies treatment requirement completely, and when what using, ask to still do not exceed 2min, it is the 1/20 that decides man-hour formerly only, still can examine at the same time with it the after casting blemish and treatment of body of a powerful person total check working procedure of semifinished product oil duct, appearance, the effect is very apparent. We had expanded this kind of method application went to all casting nowadays underline, semifinished product examines, form is complex working procedure examines and the total check after these spare partses are machined, all obtained very good result.
