Lub hauv paus chiv keeb ntawm lub npe ntawm qhov txias txiav saw:

Hlau txias sawing yog luv luv rau cov txheej txheem sawing ntawm hlau ncig saws. Lus Askiv lub npe: Circular Cold Sawing .In the process of metal sawing, the heat generated when the sawb saw hniav saws lub workpiece yog pauv mus rau sawdust los ntawm cov saw hniav, thiab sawed workpiece thiab saw hniav yog khaws cia txias, yog li nws hu ua txias sawing.

Hom khaub thuas saws:

Kev kub ceev steel saw hniav (HSS) thiab TCT insert alloy saw hniav

Cov ntaub ntawv ntawm high-speed steel saw hniav feem ntau suav nrog M2 thiab M35. Qhov dav dav sawing ceev ntawm cov saw hniav yog nyob nruab nrab ntawm 10-150 m / s, nyob ntawm cov khoom thiab specification ntawm sawing workpiece; lub coated high-speed steel saw hniav, sawing ceev tuaj yeem ncav cuag 250 m / min. Cov hniav pub tus nqi ntawm cov hniav yog nyob nruab nrab ntawm 0.03-0.15 hli / tus hniav, nyob ntawm seb lub zog, lub zog thiab qhov zoo ntawm cov saw hniav ntawm cov cuab yeej sawing.

Sab nraud txoj kab uas hla: 50-650 mm; Lub hardness ntawm cov saw hniav yog HRC 65; sawb tuaj yeem ua hauv av, nyob ntawm qhov loj ntawm sawing workpiece, feem ntau nws tuaj yeem ua hauv av 15-20 zaug. Lub neej sawing ntawm saw hniav yog 0.3-1 square meters (qhov chaw ntawm lub ntsej muag kawg ntawm lub sawing workpiece) thiab cov specification ntawm lub loj-ceev hlau saw hniav; Feem ntau, cov high-speed steel nrog inserts yog siv (tseem muaj nyob rau saum 2000 mm); cov hniav yog ua los ntawm high-speed steel nrog inserts, thiab cov saw Lub substrate ntawm daim ntawv yog vanadium hlau los yog manganese hlau.

Cov khoom siv ntawm TCT hniav alloy yog tungsten steel; qhov dav dav sawing ceev ntawm cov saw hniav yog nruab nrab ntawm 60-380 m / s, nyob ntawm seb cov khoom thiab specification ntawm sawing workpiece; tus hniav pub tus nqi ntawm tungsten steel saw hniav yog nruab nrab ntawm 0.04-0.08.

Pom hniav specification: 250-780 mm; muaj ob hom TCT saw hniav rau txiav hlau, ib qho yog cov hniav me me, cov saw hniav yog nyias, sawing ceev yog siab, saw hniav ntev ntev, txog 15-50 square meters; nws yog ib tug muab pov tseg ib tug loj cov hniav, cov saw hniav yog tuab, thiab cov sawing ceev yog tsawg, uas yog haum rau sawing loj-scale workpieces; txoj kab uas hla ntawm cov saw hniav tuaj yeem ncav cuag ntau dua 2000 hli. Kev pab cuam lub neej ntawm cov saw hniav feem ntau yog hais txog 8 square metres, thiab nws tuaj yeem ua hauv av 5-10 zaug.

Qhov txawv ntawm kev kub ceev steel txias txiav pom thiab manganese hlau ya pom:

Txias sawing yog txawv ntawm kev sib txhuam sawing, feem ntau nyob rau hauv txoj kev txiav:

Manganese steel ya saw hniav: Manganese hlau pom hniav tig ntawm kev kub ceev thiab rub tawm tsam cov khoom ua haujlwm thiab kev sib txhuam pom hniav. Thaum lub sij hawm sawing txheej txheem, qhov kub ntawm kev sib txhuam pom thiab lub workpiece yog siab heev, thiab lub tshav kub generated los ntawm kev sib cuag nrog cov welded yeeb nkab ua rau nws disconnect, uas yog burnt tiag tiag. . High burn marks yog pom ntawm qhov chaw.

High-speed steel txias txiav saw: cia siab rau lub high-speed steel saw hniav kom tig maj mam mus zeb cov welded yeeb nkab, yog li nws yuav ua tau burr-dawb thiab tsis muaj suab nrov.
