1. Cov cuab yeej siv thiab Geometry xaiv
Kev xaiv cov cuab yeej yog qhov tseem ceeb rau kev ua cov tooj liab ntshiab. Cov tooj liab ntshiab ua rau cov chips ntev, tsis tu ncua thiab yooj yim ua raws li kev txiav ntug, ua rau ua rau -nce ntug (BUE) thiab cov khoom tsis zoo.
Carbide cov cuab yeej nrog siab hardness thiab hnav tsis kam yog qhov kev xaiv tshaj plaws. Uncoated zoo-grain carbide lossis cov cuab yeej nrog TiN txheej zoo tuaj yeem txo kev sib txhuam thiab adhesion. High-cov cuab yeej steel ceev kuj tseem siv rau qis- ceev machining tab sis hnav sai dua.
Cov cuab yeej geometry yuav tsum tsom rau kev txo cov quab yuam thiab adhesion. Lub kaum sab xis loj yog pom zoo kom txo qis deformation thiab txiav cov cua sov. Ib tug ntse txiav ntug pab txo cov khoom extrusion thiab adhesion. Lub kaum sab xis kom zoo tiv thaiv kev sib txhuam ntawm cov cuab yeej flank thiab cov khoom ua haujlwm. Polished rake ntsej muag muaj txiaj ntsig zoo los txo cov nti nplaum thiab txhim kho nti ntws.
2. Txiav Parameters Optimization
Ntshiab tooj liab yog mos tab sis nplaum, yog li qhov tsis tsim nyog yuav ua rau cov cuab yeej hnav hnyav thiab ua kom tsis zoo.
Feem ntau, kev txiav ceev ceev, nruab nrab pub tus nqi, thiab qhov tob ntawm kev txiav yog tsim nyog. Kev kub ceev pab ua kom cov chips tawg thiab txo qis ua - nce ntug. Txawm li cas los xij, kev kub ceev heev ua rau cov cuab yeej hnav.
Pub tus nqi yuav tsum tsis txhob tsawg dhau, vim qhov no yuav ua rau kev sib txhuam thiab extrusion ntau dua li txiav. Ib qho me me pub pab tsim cov chips ruaj khov. Qhov tob ntawm kev txiav yog txiav txim los ntawm ib feem rigidity; ib yam nkaus thiab- qhov txiav ntiav feem ntau ua rau cov khoom tsis zoo vim yog cov cuab yeej rub tawm.
3. nti tswj thiab tshem tawm
Ntshiab tooj liab feem ntau ua rau ntev, curly, thiab tsis tawg chips uas tuaj yeem yooj yim qhwv ib ncig ntawm lub cuab yeej lossis cov khoom ua haujlwm, khawb lub tshuab ua haujlwm, lossis ua rau muaj kev nyab xeeb.
Kev tswj chip zoo suav nrog:
Siv cov cuab yeej nrog chip-breaker grooves rau curl thiab tawg chips.
Siv cov kua txiav kom txaus los pab tshem tawm cov chips.
Kho cov kev txwv txiav los txhawb cov nti tawg.
Kev tshem tawm nti tsis tu ncua thaum lub sij hawm machining yog qhov tseem ceeb kom tswj tau qhov chaw tiav thiab qhov tseeb qhov tseeb.
4. Daim ntawv thov kua
Txiav kua yog ib qho tseem ceeb heev nyob rau hauv cov ntshiab tooj liab machining. Nws muab cov cua txias, lubrication, thiab nti flushing, txo qhov adhesion thiab ua tau - nce ntug.
Cov roj ntxhia-raws li cov kua los yog cov roj emulsified uas muaj lubricity zoo yog feem ntau siv. Lawv txo cov kev sib txhuam ntawm cov cuab yeej, nti, thiab cov khoom ua haujlwm, txo qhov kub thiab txias, txhim kho qhov chaw tiav, thiab ua kom lub neej ntev. Qhuav machining feem ntau tsis pom zoo tshwj tsis yog nyob rau hauv qhov tshwj xeeb siab - ceev ceev.
5. Workpiece Fixturing thiab Rigidity
Ntshiab tooj liab muaj tsawg rigidity thiab yooj yim rau deform nyob rau hauv clamping quab yuam los yog txiav quab yuam. Tshaj -clamping yuav ua rau elastic los yog yas deformation, ua rau muaj qhov tsis zoo.
Fixturing cov ntsiab lus:
Siv cov clamping quab yuam kom tsis txhob deformation hauv zos.
Ua kom thaj chaw tiv tauj kom txo qis.
Txhawb nyias- cov phab ntsa kom txaus los tiv thaiv kev co.
Xyuas kom ruaj khov teeb kom tsis txhob muaj kev sib tham, uas ua rau tsis zoo ntawm qhov roughness.
6. Nto Zoo thiab kam rau siab tswj
Vim nws cov ductility siab, cov tooj liab ntshiab yog qhov ua rau lub caij nplooj ntoos hlav- rov qab, burrs, thiab qhov chaw tsis zoo.
Txhawm rau txhim kho qhov zoo:
Khaws cov cuab yeej ntse txhua lub sijhawm.
Siv qhov kawg kawg hla nrog me me pub thiab ceev kom tsim nyog.
Tshem tawm burrs tam sim ntawd tom qab machining.
Tswj ib puag ncig qhov kub thiab txias, raws li tooj liab muaj thermal expansion, uas cuam tshuam rau precision qhov ntev.
7. Kev zam kom tsis txhob muaj kab mob thiab oxidation
Ntshiab tooj liab nto yog tshuaj lom neeg thiab yooj yim oxidized los yog kab mob los ntawm kev txiav kua, plua plav, los yog tes hws.
Rau cov khoom uas yuav tsum tau plating tom qab, vuam, polishing, los yog sib dhos, tom qab-machining tu thiab anti- kev kho oxidation yog tsim nyog. Kev khaws cia kom zoo tuaj yeem tiv thaiv tsis muaj xim thiab kev ua haujlwm degradation.
Cov ntsiab lus
Machining ntshiab tooj liab yuav tsum muaj kev tswj hwm cov cuab yeej, tsis muaj, kev tswj cov nti, txiav cov kua dej, fixturing, thiab post- ua. Qhov kev sib tw tseem ceeb yog kov yeej nws cov nplaum, tsis tshua muaj rigidity, thiab adhesion nyiam. Nrog cov txheej txheem tsim nyog thiab kev ua haujlwm nruj, cov khoom siv tooj liab ntshiab tuaj yeem ua tiav qhov tseeb ntawm qhov tseeb thiab zoo heev ntawm qhov chaw, ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv hluav taws xob, thermal, mechanical, thiab cov ntaub ntawv zoo nkauj.
