Cov kev sib tw tseem ceeb hauv Stainless Steel Parts Machining
Stainless hlau yog dav siv nyob rau hauv kev lag luam vim nws zoo heev corrosion kuj, lub zog, thiab zoo nkauj thov. Txawm li cas los xij, nws kuj tseem nthuav tawm ntau qhov teeb meem machining tseem ceeb uas cov tuam txhab yuav tsum daws:
1. High Work Hardening Tendency
Stainless hlau, tshwj xeeb tshaj yog cov qib austenitic zoo li 304 thiab 316, pom muaj kev ua haujlwm hnyav thaum txiav. Raws li lub cuab yeej koom nrog cov khoom siv, txheej txheej saum npoo hardens sai heev, ua rau txiav quab yuam kom nce thiab ua kom cov cuab yeej hnav. Qhov no feem ntau xav tau ntau qhov kev sib tw ua ntej ua tiav kom tsis txhob ua kom puas cov cuab yeej lossis cov khoom ua haujlwm.
2. Tsis zoo thermal conductivity
Piv rau carbon steel los yog txhuas, stainless hlau muaj kuj tsis tshua muaj thermal conductivity. Feem ntau ntawm kev txiav cov cua sov concentrates ntawm lub cuab yeej-chip interface es tsis dissipating los ntawm workpiece los yog nti. Qhov kub siab no ua rau cov cuab yeej degradation, txo cov cuab yeej lub neej, thiab tuaj yeem ua rau thermal deformation ntawm lub workpiece.
3. Chip Adhesion muaj zog thiab ua tau -Up Ntug (BUE)
Stainless hlau nyhav tsim ntev, nruam chips uas ua raws li cov cuab yeej rake ntsej muag. Qhov no ua tau - qhov tshwm sim ntawm ntug kev hloov pauv cov cuab yeej geometry zoo, degrades nto tiav, thiab tuaj yeem ua rau qhov tsis txaus ntseeg qhov tseeb. Tshwj xeeb chip breakers thiab optimized txiav tsis yog qhov tseem ceeb los tswj cov chip tsim.
4. Siab txiav quab yuam thiab kev siv zog
Cov ntaub ntawv toughness thiab lub zog ua rau muaj zog txiav ntau dua thaum lub sij hawm machining. Qhov no xav tau cov cuab yeej siv tshuab nruj dua, kev kho kom ruaj khov, thiab lub zog ntxaiv ntau dua. Lub tshuab rigidity tsis txaus tuaj yeem ua rau muaj kev sib tham, cov cim vibration, thiab cov khoom tsis zoo.
5. Cov cuab yeej hnav thiab tus nqi
Kev sib xyaw ua ke ntawm qhov kub thiab txias, abrasive carbide hais nyob rau hauv cov khoom, thiab cov tshuaj reactivity ua rau cov cuab yeej hnav sai heev -tshwj xeeb tshaj yog crater hnav ntawm lub ntsej muag rake thiab flank hnav. Carbide lossis coated cov cuab yeej (TiAlN, TiCN) feem ntau yuav tsum tau, thiab txiav ceev yuav tsum tau txo qis dua piv rau lwm cov ntaub ntawv, nce lub sij hawm voj voog thiab cov cuab yeej siv.
6. Surface Finish thiab Dimensional Accuracy
Ua kom tiav qhov zoo nkauj tiav yog qhov nyuaj vim cov khoom siv nyiam smear thiab gall. Tsis tas li ntawd, qhov kev ntxhov siab uas nyob ntawm kev siv tshuab tuaj yeem ua rau muaj kev sib hloov lossis kev sib hloov, tshwj xeeb tshaj yog nyob rau hauv nyias- cov phab ntsa lossis cov duab puab, ua rau nruj tolerances nyuaj rau tswj.
7. Cov khoom sib txawv
Cov qib stainless hlau sib txawv (austenitic, martensitic, ferritic, duplex, nag lossis daus-hardening) coj txawv txawv thaum lub tshuab ua haujlwm. Piv txwv li, pub dawb- qib machining zoo li 303 muaj cov tshuaj sulfur ntxiv los txhim kho kev ua haujlwm, thaum cov qib super duplex yog qhov nyuaj heev los txiav. Kev xaiv qhov tsim nyog thiab cov cuab yeej rau txhua qib yog qhov tseem ceeb.
