Matsayin matsayi don machining na shaft 

• 1. Yi amfani da tsakiyar rami na workpiece a matsayin matsayi nuni ga machining. A cikin machining na shaft sassa, da coaxial kowane waje madauwari surface, tapered rami da thread surface, da perpendicularity na karshen surface zuwa ga juyi axis ne muhimman manifestations na matsayi daidaito. Wadannan saman an tsara su gabaɗaya tare da layin tsakiya na shaft azaman tunani kuma an sanya su tare da rami na tsakiya don dacewa da ƙa'idar daidaituwa. Ramin tsakiya ba wai kawai madaidaicin matsayi don juya machining ba, amma har madaidaicin matsayi da ma'aunin dubawa don wasu. aiwatar da aikies, wanda ya dace da ƙa'idar haɗin kai. Lokacin sanyawa tare da ramukan tsakiya guda biyu, yana yiwuwa a aiwatar da yawan da'irori na waje da fuskokin ƙarewa a cikin matsi guda ɗaya.
• 2. Da'irar waje da rami na tsakiya suna aiki azaman matsayi na mashin. Wannan hanya yadda ya kamata shawo kan shortcomings na matalauta saka rigidity na cibiyar rami, musamman a lokacin da machining wani nauyi workpiece, da sakawa na cibiyar rami iya sa clamping ya zama m, da kuma yankan adadin iya zama ma girma. Ba dole ba ne ku damu da wannan matsala ta amfani da da'irar waje da rami na tsakiya azaman bayanin matsayi. A cikin roughing, hanyar yin amfani da farfajiyar waje na shaft da rami na tsakiya kamar yadda maƙasudin matsayi na iya jure wa manyan lokutan yankan lokacin machining, wanda shine mafi yawan hanyar sakawa don sassan shaft.

A clamping na shaft

Mashin ɗin filogin mazugi da taper mandrel dole ne su kasance da madaidaicin mashin ɗin. Ramin tsakiya ba wai kawai ma'aunin matsayi ne da aka yi da kansa ba, har ma da ma'auni don kammala da'irar waje na ramin rami. Dole ne ya tabbatar da taper a kan mazugi ko mazugi hannun riga. Yana da babban matsayi na ƙaddamarwa tare da rami na tsakiya. 

 Sabili da haka, lokacin zabar hanyar ƙulla, ya kamata a lura cewa ya kamata a rage yawan shigarwa na mazugi na mazugi, don haka rage maimaita kuskuren shigarwa na sassan. A zahirin samarwa, bayan an shigar da mazugi, gabaɗaya ba a cire ko musanya shi a tsakiyar injina kafin yin injin.
