Goynta dunta
Waxaa guud ahaan loola jeedaa habka of processing threads on workpiece la samaynta qalab ama abrasives, inta badan jeestay, wax shiida, tuubada, dunta, shiidi, lugaynta iyo goynta duufaanka.Marka la leexiyo, shiidi iyo shiidi dunta, silsiladda drive ee qalabka mishiinada hubisaa in qalabka rogid, qalabka wax lagu shiidaa ama shiidi giraangiraha si sax ah iyo si siman u socdaan jihada axial of workpiece ee kacaan kasta oo workpiece ah.Tuubbada ama dunta, aaladda (tubbada ama saxanadda) waxay u dhaqaaqdaa wareegyo qaraabo ah oo u socda qaybta shaqada oo ay hagto jeexdin dunta marka hore loo sameeyay si loo dhaqaajiyo aaladda (ama workpiece) axially.
Xadhkaha loo rogo xayndaabka waxa lagu samayn karaa qalab samaynta ama shanlada dunta (fiiri Tools for Threading).Isku-rogid dunta oo leh qalab samaynta waa hab caadi ah oo loogu talagalay hal-guud iyo wax-soo-saarka yar yar ee qalabka shaqada ee dunta ah sababtoo ah qaab-dhismeedka qalabka fudud;dunta jeestay qalab shanlo dun ah waa heer sare ah wax soo saar leh, laakiin qaab-dhismeedka qalabku waa adag yahay oo kaliya ku habboon soo jeedin workpieces dun gaaban oo ilko ganaax in wax soo saarka Dufcaddii dhexdhexaad ah iyo weyn.Saxnaanta saxda ah ee dunta tarapezoidal-ka ee leexashada lathe caadiga ah waxay gaari kartaa kaliya 8 ~ 9 fasalka (JB 2886-81, isla hoos);wax soo saarka ama saxnaanta waxaa si weyn loo wanaajin karaa iyadoo la farsameeyo dunta mashiinka leexinta dunta gaarka ah.
Thread Milling
Ku-shiididda mishiinka wax-shiidka dunta leh saxan ama wax-shiidka shanlada.Warshadaynta saxanka ayaa inta badan loo isticmaalaa in lagu shiido dunta dibadda ee trapezoidal ee meelaha shaqada sida furka iyo ulaha dirxiga.Warshad-shiidoyinka shanlada waxa loo isticmaalaa miidda dunta guud ee gudaha iyo dibadda iyo dunta duuban.Tan iyo markii workpiece la shiiday la gooyay a af badan iyo dhererka qaybta shaqada ka weyn tahay dhererka dunta in la mashiin, workpiece la mashiin karaa oo kaliya 1.25 in 1.5 kacaanka, taasoo keentay in wax soo saarka sare.Saxnaanta garoonka shiidida duntu guud ahaan waa 8-9 darajo.Habkani wuxuu ku habboon yahay wax soo saarka dufcada shaqada dunta ee saxnaanta guud ama mashiinnada qallafsan ka hor inta aan la shiidi.
Duubista dunta
Waxaa inta badan loo isticmaalaa in lagu farsameeyo dunta saxda ah ee qalabyada adag ee mashiinada wax shiida.
Shiididda dunta waxaa loo qaybiyaa hal dun shiidi giraangiraha iyo multi thread shiidi giraangiraha iyadoo la raacayo qaabka shiidi qaybta cross wheel.Shiidi dunta kali ah waxay gaari kartaa saxnaanta garoonka ee 5 ~ 6, qallafsanaanta dusha sare ee Ra1.25 ~ 0.08 micron, iyo lebbiska taayirrada fudud.
Habkani waxa uu ku haboon yahay in la shiido boolal sax ah, cabirrada dunta, gears dixiriyada, workpieces dun-badan oo yar iyo majarafad shiidi saxan saxan.Shiididda Multiline waxay u qaybsantaa laba nooc: shiididda dhaadheer iyo shiididda.Habka shiidida dhererka, ballaca giraangiraha shiidadu wuu ka yar yahay dhererka dunta in la jeexo, giraangiraha wax lagu shiidana waxa loo dhaqaajin karaa si dheer oo hal ama dhawr istaroog ah si uu dunta u shiiddo cabbirkiisa ugu dambeeya.Habka shiididda, ballaca giraangiraha shiidadu waa ka weyn yahay dhererka dunta in la dhigo, iyo giraangiraha shiidadu waa la gooyaa radially dusha sare ee workpiece, iyo workpiece waxay noqon kartaa dhul ku saabsan 1.25 kacdoon, sidaas darteed. wax soo saarku wuu sarreeyaa, laakiin saxnimadu wax yar bay ka hoosaysaa oo dhaymada giraangiraha shiidadu waa ka sii adag tahay.Habka shiididdu waxay ku habboon tahay majarafad tiro badan oo qasabad ah iyo shiididda dunta qaarkood si loo xidho.
