Lub rooj sib tsoo steel yog tsuas yog siv nyob rau hauv thawj zaug tsim kho lub sijhawm ntawm cov fais fab nroj tsuag los kho cov kab sib txig ntawm cov nqaj hlau los yog teeb tsa thiab kho cov khoom siv kho tshuab thiab tshuab twj. Cov hlau oblique hlau tsuas yog siv rau kev tsim kho thiab kho cov qauv steel, ntxiv rau kev teeb tsa thiab kev kho kom haum ntawm cov khoom siv; cov yam ntxwv yog: du nto, siab precision, tsis muaj burrs nyob ib puag ncig, zoo toughness, thiab yooj yim siv

Cov kev cai ntawm kev sib tsoo Steel: qhov tseeb raug txiav txim siab raws li qhov xav tau, vim tias cov npoo npoo feem ntau siv sab saud thiab sab qis, yog li cov tseev kom muaj rau plaub sab yog feem ntau tsis siab, thiab qhov roughness ntawm steel wedge yog 6.4; Kev sib txhuam ntawm qhov chaw ntawm sab saud thiab qis dua ntawm kev sib tsoo yog 12,5, 6.4, 3.2, 0.8, thiab lwm yam, yog tias qhov ua tau siab dua, lub tiaj thiab parallelism ntawm cov hlau sib tsoo ua los ntawm kev sib tsoo tsis ntau tshaj 0.03mm. Lub tuab ntawm cov txheej txheem steel tuaj yeem txiav txim siab raws li qhov xav tau tiag tiag thiab cov khoom siv thiab qhov tshwj xeeb ntawm cov khoom; txoj kab nqes ntawm cov hlau npoo yuav tsum yog 1 / 10-1 / 20, lub rooj sib tsoo steel ntawm kev co lossis cov cuab yeej siv hluav taws xob Qhov nqes ntawm lub khaum) tuaj yeem yog 1/40. Thaum siv hlau npoo, nws yuav tsum tau siv rau hauv kev sib xyaw nrog lub tiaj tus sib tsoo ntawm tib yam kev ntsuas. Lub rooj zaum steel yuav tsum tau siv ua khub. Tib txoj kab nqes yuav tsum siv.
Cov duab kos ntawm lub npoo steel yog tsim raws li qhov tseeb cov khoom siv hauv paus, thiab tom qab ntawd ua raws li cov duab kos.

Yuav ua li cas siv lub tog hlau
Tso lub tiaj tiaj rau ntawm cov pob zeb tsev, thiab tom qab ntawd tso ob daim hlau npoo ntawm cov tiaj tiaj. Thaum hloov kho, siv rab rauj los tsoo ob lub viav hlau tsoo, txoj kab nqes ntawm cov npoo hlau yog siv los tsa lossis qis dua cov cuab yeej ua tiav lub hom phiaj ntawm kev kho qib. Tom qab qib raug hloov kho, pom cov hlau pob zeb sib tsoo nrog lub hauv paus ntawm cov khoom siv los ua kom lub ntsej muag thiab ruaj. Thaum kawg, nws tau nchuav nrog cov pob zeb ua kom cov cuab yeej ua tau zoo nyob rau lub sijhawm ua haujlwm, txo lub tshuab hnav thiab kua muag, thiab txo tus nqi hloov pauv ntawm cov khoom siv.
