1. Tolerances rau cov kais dej ntawm cov qib precision sib txawv
Cov qib raug ntawm tus kais dej tsis tuaj yeem xaiv thiab txiav txim siab tsuas yog raws li qib raug ntawm cov xov yuav tsum tau ua, Nws tseem yuav tsum xav txog:
(1) cov khoom thiab hardness ntawm lub workpiece yuav tsum machined;
(2) Cov khoom siv tapping (xws li cov cuab yeej siv tshuab, cov cuab yeej clamping, lub nplhaib txias, thiab lwm yam);
(3) Precision thiab manufacturing yuam kev ntawm tus kais nws tus kheej.
Piv txwv li: ua 6H xov, thaum ua ntawm steel qhov chaw, 6H precision kais tuaj yeem xaiv tau;Hauv kev ua haujlwm ntawm grey cam khwb cia hlau, vim hais tias qhov nruab nrab txoj kab uas hla ntawm tus kais hnav sai dua, qhov nthuav dav ntawm lub qhov ntsia hlau tseem me me, yog li nws tsim nyog xaiv 6HX precision kais, lub neej yuav zoo dua.
Kev piav qhia ntawm qhov tseeb ntawm JIS kais:
(1) Txiav kais OSG siv OH precision system, txawv ntawm ISO cov qauv, OH precision system yuav yuam kom dav ntawm tag nrho cov kev kam rau ua ib cheeb tsam ntawm qhov qis tshaj, txhua txhua 0.02 hli raws li qhov raug, npe OH1, OH2, OH3, thiab lwm yam. ;
(2) Extrusion kais OSG siv RH raug qhov system, RH raug qhov system yuam qhov dav ntawm tag nrho cov kev kam rau ua kom pib los ntawm qhov qis tshaj, txhua txhua 0.0127mm raws li qhov raug, npe RH1, RH2, RH3 thiab lwm yam.
Yog li ntawd, thaum siv ISO precision kais los hloov OH precision kais, nws tsis tuaj yeem suav hais tias 6H yog hais txog qhov sib npaug ntawm OH3 lossis OH4 qib, uas yuav tsum tau txiav txim siab los ntawm kev hloov pauv, lossis raws li qhov tseeb ntawm cov neeg siv khoom.
2. Sab nraud loj ntawm kais
(1) Tam sim no, feem ntau siv yog DIN, ANSI, ISO, JIS, thiab lwm yam;
(2) Xaiv qhov tsim nyog tag nrho ntev, hniav ntev thiab tuav square loj raws li kev ua haujlwm sib txawv lossis cov neeg siv khoom uas twb muaj lawm;
(3) Kev cuam tshuam thaum ua haujlwm.
3. 6 lub hauv paus ntsiab lus ntawm kais xaiv
(1) Hom xov ua, metric, British, Asmeskas, thiab lwm yam .;
(2) Hom xov hauv qab lub qhov, los ntawm lub qhov los yog qhov muag qhov muag;
(3) Cov khoom thiab hardness ntawm lub workpiece yuav tsum machined;
(4) Qhov tob ntawm cov xov tiav ntawm lub workpiece thiab qhov tob ntawm lub qhov hauv qab;
(5) Lub precision yuav tsum tau los ntawm workpiece xov;
(6) Zoo li tus qauv ntawm kais.
