Yuav ua li cas xaiv cov khoom siv tapping thiab txheej?

Thaum peb tapping threads, muaj ntau hom kais dej rau koj xaiv los ntawm.Peb tuaj yeem xaiv lawv li cas?Xws litapping hardened hlau, tapping cam khwb cia hlau, lossis tapping aluminium, peb yuav ua li cas?

1. High-speed steel: Tam sim no dav siv los ua kais khoom, xws li M2 (W6Mo5Cr4V2, 6542), M3, thiab lwm yam, peb hu nws HSS.

2. Cobalt high-speed steel: Tam sim no dav siv los ua cov khoom siv kais dej, xws li M35, M42, thiab lwm yam, nws hu ua HSS-E.

3. hmoov metallurgy high-speed steel: siv los ua cov khoom siv kais dej, nws qhov kev ua tau zoo tau zoo dua qub piv rau ob qho saum toj no, thiab cov txheej txheem naming ntawm txhua qhov chaw tsim khoom kuj txawv, nrog rau cov cim cim yog HSS-E-PM .

4. Tungsten carbide: feem ntau xaiv ultrafine carbide qib, feem ntau yog siv rau kev tsim cov raj nplaim ncaj kais ua cov ntaub ntawv luv luv, xws li carbide kais dej rau grey cam khwb cia hlau, carbide kais rau cov hlau tawv,carbide kais rau aluminium, thiab lwm yam, peb hu nws carbide kais.

Threading taps

ntau cia siab rau cov ntaub ntawv, thiab xaiv cov ntaub ntawv zoo tuaj yeem ua kom zoo dua cov txheej txheem ntawm cov kais dej, ua rau nws tsim nyog rau kev ua haujlwm zoo thiab xav tau ntau dua, thaum tseem muaj lub neej ntev dua.

Txheej ntawm kais

1. Chav oxidation: Cov kais dej tau muab tso rau hauv cov dej kub kub los ua ib txheej ntawm oxide zaj duab xis rau ntawm nws qhov chaw, uas muaj qhov zoo adsorption ntawm lub coolant thiab tuaj yeem txo kev sib txhuam, thaum tiv thaiv adhesion ntawm cov kais dej thiab cov khoom raug txiav.Nws yog tsim rau kev ua cov hlau mos.

2. Nitriding kev kho mob: Qhov saum npoo ntawm tus kais dej yog nitrided los ua ib txheej txheej tawv tawv, haum rau kev ua cov ntaub ntawv xws li cam khwb cia hlau thiab cam khwb cia txhuas uas muaj kev hnav tsis kam rau cov cuab yeej txiav.

3. TiN: Golden daj txheej, nrog zoo txheej hardness thiab lubrication, thiab zoo txheej adhesion kev ua tau zoo, haum rau kev ua cov ntaub ntawv feem ntau.

4. TiCN: Blue grey txheej, nrog ib tug hardness ntawm kwv yees li 3000HV thiab ib tug kub tsis kam mus txog 400 ° C.

5. TiN + TiCN: sib sib zog nqus daj txheej nrog zoo heev txheej hardness thiab lubrication, haum rau kev ua cov ntaub ntawv feem ntau.

6. TiAlN: Blue grey txheej, hardness 3300HV, tshav kub tsis kam mus txog 900 ° C, haum rau high-speed machining.

7. CrN: Silver grey txheej nrog lubrication kev ua tau zoo, feem ntau yog siv rau kev ua cov hlau tsis muaj hlau.
