Yuav ua li cas tshuab S960Q steel?
Machining S960Q steel yog qhov nyuaj heev vim nws lub zog ultra- siab zog (960 MPa tawm los) thiab siab hardness (feem ntau 300-400 HBW). Nws yuav tsum muaj cov cuab yeej tshwj xeeb, kev teeb tsa nruj, thiab kev tswj xyuas qhov tseeb kom tsis txhob muaj cov cuab yeej siv ntau dhau, kev ua haujlwm puas, lossis tsis ua haujlwm. Hauv qab no yog cov lus qhia tseem ceeb:
1. Cov Ntsiab Lus Tseem Ceeb
High Cutting Forces:Xav tau lub tshuab siab tshaj plaws kom tsis txhob muaj kev vibration / sib tham.
Rapid Tool Wear:Lub siab hardness thiab abrasive alloy carbides ua rau ceev ntug degradation.
Thaum tshav kub kub tiam:Kev sib txhuam hnyav ua rau muaj cua sov siab, ua rau muaj kev pheej hmoo ntawm cov cuab yeej tsis ua haujlwm thiab muaj peev xwm hloov pauv ntawm cov hlau cua sov- kho cov khoom.
Ua Haujlwm Hardening:Kev ua haujlwm tsis raug (xws li, tus nqi qis qis, cov cuab yeej hnav) tuaj yeem ua kom tawv nqaij ntxiv, ua rau kev hla dhau los nyuaj dua.
2. Kev xaiv cov cuab yeej
Khoom siv: Siv hwm- qib micro-grain carbide (C4 / C5 qib) nrog TiAlN / AlCrN / TiSiN txheej. Rau roughing, ceramic inserts (Si₃N₄ los yog Al₂O₃-based) yuav siv tau nyob rau hauv qhov chaw ruaj khov, kev kub ceev.
Geometry: Zoo rake cov ces kaum, ntse npoo, thiab polished flutes kom txo tau txiav quab yuam. Cov cuab yeej muaj zog (piv txwv li, hydraulic, shrink-fit) yog qhov tseem ceeb rau rigidity.
Kev soj ntsuam cov cuab yeej: Tshawb xyuas cov cuab yeej nquag hnav; hloov ntawm thawj cov cim qhia ntawm ntug deterioration.
3. Kev Txiav Txim (Cov ntsiab lus pib dav dav)
Txiav ceev (Vc): Tsawg mus rau nruab nrab - feem ntau 50-100 m / min rau tig nrog carbide. Pib ntawm qis kawg.
Feed Rate: Siv cov khoom noj kom txaus (xws li, 0.1–0.25 mm / rev rau tig) kom tsis txhob rub thiab ua haujlwm tawv.
Qhov tob ntawm Kev Txiav: Txaus los txiav hauv qab cov txheej txheej tawv tawv (Ntau dua lossis sib npaug li 0.5 hli rau kev ua tiav).
Nco tseg: Cov no yog cov ntsiab lus pib; ib txwm xa mus rau cov lus pom zoo ntawm cov neeg siv khoom thiab ua cov kev txiav txim siab.
4. Coolant & Lubrication
High-pressure coolant (Ntau dua los yog sib npaug rau 80 bar) yog qhov tseem ceeb rau dissipate tshav kub, txhim kho nti khiav tawm, thiab ua kom lub neej ntev.
Siv emulsion los yog roj-raws li coolants nrog zoo heev lubrication thiab thermal conductivity.
5. Txheej txheem-Cov lus qhia tshwj xeeb
Tig: Siv lub teeb-rau- nruab nrab qhov tob ntawm kev txiav. Xyuas kom meej tias lub workpiece yog ruaj ntseg chucked kom txo deflection.
Milling: Nyiam nce milling (down-milling) kom txo tau cua sov thiab ua hauj lwm hardening. Siv cov cuab yeej nrog txo tus naj npawb ntawm flutes kom zoo dua nti tshem tawm.
Drilling & Tapping:
Drilling: Siv cov laum carbide nrog cov cua txias sab hauv. Peck drilling yog qhov yuav tsum tau ua rau qhov tob tob.
Tapping: Zam yog tias ua tau; xov milling yog xav pom zoo rau kev tswj kom zoo dua thiab lub neej ntawm lub cuab yeej. Yog tias tapping tsis tuaj yeem zam tau, siv cov kais dej uas muaj zog thiab ua kom muaj kev sib raug zoo.
6. Kev Npaj & Teeb
Tshem Tawm Hard Surface Scale: Cov phaj xa khoom feem ntau muaj tawv tawv, decarburized. Tshem nws ntawm kev sib tsoo los yog ntxhib machining ua ntej ua tiav cov haujlwm.
Maximize Rigidity: Siv lub tshuab muaj zog tshaj plaws. Txo qhov overhang ntawm cov cuab yeej thiab workpieces. Cov tuav cov cuab yeej damped tuaj yeem pab txo kev vibration.
Kev Ruaj Ntseg Ua Haujlwm: Siv hydraulic lossis mechanical clamping los tiv thaiv kev txav mus los hauv siab txiav quab yuam.
