Yuav ua li cas xaiv hloov cov ntxig rau kev tshawb fawb?

Kev xaiv ntawm tig cov ntxig rau kev siv tshuab kev ua tau zoo, cuab yeej lub neej thiab ua haujlwm zoo. Cov tshuaj xyuas cov hauv qab no Qhov kev txiav txim siab tseem ceeb ntawm tsib qhov ntev: Khoom siv khoom, cov khoom siv ntsuas duab, tshuab tshuab, machining scararios thiab kev lag luam.

•  Cov Khoom Siv Hniav: "Hardness" txuam nrog cov khoom ua

Kev faib tawm ntawm cov qhab nia carbide

1. YG hom (cobalt-based): Haum rau cam khwb cia hlau thiab tsis-ferrous hlau, xws li yg6x (yg3x (xov machining)

2. YT hom (titanium-raws): siv rau kev txiav cov hlau, xws li yt15 (dav dav), yt30 (xov machining)

3. YW hom (universal alloy): thawj qhov kev xaiv rau cov hlau tsis muaj cua sov thiab cua sov tiv thaiv, xws li YW1 (dav dav), yw2 (hnav-resistant)

4. Cov Khaub Ncaws Pob Muaj Zog: Haum rau Cov Ntaub Ntawv High-hardness (HRC45 thiab siab dua), tab sis nkig thiab koj yuav tsum tau noj

5. CBN Blades: Qhov kev xaiv qhov kawg rau kev nrawm nrawm ntawm cov hlau hardened (HRC55 +) thiab cam khwb cia hlau

   
   

• Geometric tsis muaj: qhov "tsis pom txoj cai" uas txiav txim txiav kev ua haujlwm

 1.TIP RADIUS (Rε)

• Ntxhib machining: 0.8-1.2mm (nce lub zog)

• Zoo machining: 0.4-0.8mm (txo cov av roughness)

• Sib quas ntus txiav yuav tsum muaj vojvoog me me los txo kev cuam tshuam

 2.Qhov kaum (γ0)

• Rake lub kaum sab xis (8 ° -15 °): tsis tshua muaj zog, haum rau txhuas alloys thiab stainless hlau

• Kev tsis zoo rake lub kaum (,5 ° -0 °): high rigidity, siv rau cov hlau thiab cam khwb cia hlau

 3.back kaum (α0)

• Ntxhib machining: 6 ° -8 ° (txo cov khoom hnav rov qab)

• Tshuab zoo heev: 10 ° -12 ° (txo kev sib txhuam)

 4. Tawm Tawm Kho

• Honning ntug (0.02-0.05mm): kev ua dav dav

• Chamfed ntug (0.05-0.2mm × -15 °): sib dhos txiav thiab tiv thaiv chipping

• Txheej thev naus laus zis: "Khawv koob ua rog" uas nce lub neej

1.Geler Txheej

• Tialn (kub): tiv taus cov kub oxidation siab (1100 ° C), haum rau cov hlau seem

• Ticn (Grey): Siab Hardness, Haum rau cam khwb cia hlau

• Alcrn (xiav-grey): anti-adhesion hauv stainless hlau ua

2.Special Txheej

• Pob zeb diamond txheej: ultra-nplua ua ntawm txhuas alloy thiab graphite

• Puas yog txheej (xws li Tialn + Mos2): Anti-txhuam hauv Stainless Hlau Sib Sib Zog Ua

• Ua Cov Teeb Meem Raug Cai: Kev daws teeb meem zoo nyob hauv qab kev ua haujlwm sib txawv

• Siv kev txawj: Ceev kev kuaj hniav tsis ua haujlwm

• Flank hnav (vb> 0.3mm): Txheej tsis ua haujlwm lossis ntau dhau noj

• 0.3mm): Txheej tsis ua haujlwm lossis ntau dhau noj

• Tawg ntug: tsis txaus ntug lub zog, yuav tsum tau nce chamfer lossis txo qhov txiav txiav

• Built-up ntug: qhov ntsuas kub qis, ua kom ceev ceev lossis siv cov sulphur-muaj txheej txheej
