Cov txheej txheem ua cov cuab yeej

Cov cuab yeej dov tuaj yeem siv cov yas deformation ntawm cov hlau ntawm chav tsev kub kom flatten lub microscopic unevenness ntawm workpiece nto, yog li hloov cov qauv nto, txhua yam khoom, cov duab thiab loj. Yog li, txoj kev no tuaj yeem ua tiav ob qho tib si tiav thiab ntxiv dag zog rau tib lub sijhawm, uas tsis tuaj yeem ua tiav los ntawm kev sib tsoo thiab tig. Tsis muaj teeb meem dab tsi ntawm cov cuab yeej siv hlau siv rau kev ua, yuav tsum muaj cov cuab yeej zoo tsis sib xws ntawm qhov chaw, thiab yuav muaj staggered peaks thiab hav. Ib qho kev nyuaj siab yuav ua rau cov hlau saum npoo ntawm lub workpiece ntws los ntawm plastically thiab sau rau hauv cov seem uas tsis tshua muaj concave troughs, yog li txo qhov roughness ntawm lub workpiece. Vim yog cov yas deformation ntawm cov dov saum npoo hlau, cov qauv saum npoo yog txias hardened thiab cov nplej yog refined, tsim ib tug tuab fiber ntau, thiab ib tug residual kev nyuaj siab txheej yog tsim, lub hardness thiab lub zog yog zoo dua, yog li txhim kho cov hnav tsis kam, corrosion kuj thiab compatibility ntawm workpiece nto. Rolling yog ib txoj kev ua cov yas uas tsis yog txiav.

 

Inner cone dov cutter

Rolling cutters tsis muaj hniav. Kev siv thev naus laus zis muaj kev nyab xeeb thiab yooj yim. Lawv tuaj yeem siv tau rau txhua qhov kev lag luam hlau thiab tuaj yeem tswj xyuas qhov tseeb. Muaj ntau qhov zoo tshaj plaws:

Sab nraud cone dov cutter

1. Txhim kho nto roughness. Qhov roughness tuaj yeem ncav cuag Ra Tsawg dua lossis sib npaug rau 0.08µm.

2. Kho kom raug roundness. Lub ovality yuav ua tau tsawg dua los yog sib npaug rau 0.01mm.

3. Txhim kho deg hardness, tshem tawm kev ntxhov siab deformation, thiab nce hardness HV ntau dua los yog sib npaug rau 4 degree

4. Muaj cov txheej txheem kev ntxhov siab seem tom qab ua tiav, uas ua rau kom qaug zog ntawm 30%.

5. Txhim kho qhov zoo sib xws, txo kev hnav, thiab txuas ntxiv lub neej kev pab cuam ntawm cov khoom, tab sis cov nqi ua haujlwm ntawm cov khoom raug txo. Daim ntawv thov kev ua haujlwm siab - qhov saum npoo tuaj yeem ua tiav raws li qhov yuav tsum tau muaj qhov tseeb hauv ob peb vib nas this, thiab qhov ua tau zoo yog 5-20 zaus ntawm kev sib tsoo thiab 10-50 zaus ntawm kev tig.

 

Hla-qhov dov cutter

Zoo siab - Ua tiav daim iav nto qhov tseeb ntawm Ra0.05-0.1um hauv ib qho kev pub mis; thiab ua rau saum npoo extrusion hardened, txhim kho hnav tsis kam thiab qaug zog; tshem tawm qhov kev ntxhov siab ntawm cov yas deformation, thiab qhov tseeb qhov tseeb tuaj yeem nyob ruaj khov rau lub sijhawm ntev.

 

Qhov muag tsis pom qhov dov cutter

Kev lag luam - Tsis tas yuav tsum tau nqis peev rau hauv cov khoom siv loj, kev ua haujlwm hauv av, kev siv hluav taws xob, kev kho slag pov tseg, thiab lwm yam; Tsis tas yuav nqis peev pab rau cov kws tshaj lij. Yooj yim - tuaj yeem clamped rau txhua qhov kev sib hloov thiab cov khoom siv pub mis, thiab tuaj yeem ua tiav nrog daim iav qhov tseeb qhov tseeb yam tsis muaj kev cob qhia. Kev tiv thaiv ib puag ncig - tsis muaj chips (tiv thaiv ib puag ncig), kev siv hluav taws xob tsawg. Kev nyab xeeb - Tsis muaj cov cuab yeej txiav dov tsis muaj cov hniav. Rolling taub hau yog muab faib ua dov taub hau rau cov tshuab dhos zoo tib yam thiab qhov sib sib zog nqus qhov dov taub hau rau qhov sib sib zog nqus qhov drilling thiab tho txawv tshuab. Cov saum toj no yog dov lub taub hau rau cov tshuab dhos zoo tib yam, thiab qhov no yog lub taub hau dov rau qhov sib sib zog nqus qhov drilling thiab tho txawv tshuab.
