Kev Siv Tshuab
Sib tsoo tshuab
Grinder yog cov cuab yeej siv tshuab uas siv cov cuab yeej abrasive los zom cov workpiece nto.Feem ntau cov grinders siv high-speed rotating sib tsoo log rau kev sib tsoo, thaum ob peb siv oilstone, abrasive siv thiab lwm yam abrasives thiab dawb abrasive ua, xws li honing zeb, superfinishing tshuab cuab tam, abrasive siv grinder, grinder thiab polishing tshuab.
Kev ua haujlwmNtau yam
Grinders tuaj yeem ua cov ntaub ntawv nrog cov tawv tawv dua, xws li cov hlau tawv tawv, tawv alloy, thiab lwm yam; Nws tseem tuaj yeem ua cov khoom siv tawv tawv, xws li iav thiab granite. Lub grinder tuaj yeem zom nrog qhov siab precision thiab me me roughness, thiab tseem tuaj yeem zom nrog kev ua haujlwm siab, xws li kev sib tsoo muaj zog.
Sib tsoo kev txhim kho keeb kwm
Nyob rau xyoo 1830, txhawm rau hloov mus rau kev ua haujlwm ntawm cov khoom tawv tawv xws li moos, tsheb kauj vab, tshuab xaws thiab phom, Tebchaws Askiv, Lub Tebchaws Yelemees thiab Tebchaws Meskas tau tsim cov tshuab grinders siv lub log uas siv lub log. Cov grinders no tau rov ua dua los ntawm kev ntxiv cov taub hau sib tsoo rau cov cuab yeej siv tshuab uas twb muaj lawm thaum lub sijhawm ntawd, xws li lathes thiab planers. Lawv tau yooj yim hauv cov qauv, tsis tshua muaj zog, thiab yooj yim los tsim kev vibration thaum sib tsoo. Cov neeg ua haujlwm yuav tsum muaj kev txawj ntse los txiav cov workpieces meej.
universal cylindrical grinder tsim los ntawm Brown Sharp Company ntawm Tebchaws Meskas, uas tau nthuav tawm ntawm Paris Expo xyoo 1876, yog thawj lub tshuab nrog cov yam ntxwv ntawm cov tshuab niaj hnub. Nws workpiece taub hau ncej thiab tailstock yog ntsia rau ntawm reciprocating workbench. Lub thawv zoo li lub txaj txhim kho lub rigidity ntawm lub tshuab cuab yeej, thiab yog nruab nrog sab hauvsib tsooaccessories. Nyob rau hauv 1883, lub tuam txhab ua ib tug nto grinder nrog ib tug sib tsoo lub taub hau mounted rau ib kem thiab ib tug workbench tsiv rov qab thiab tawm.
Nyob ib ncig ntawm 1900, txoj kev loj hlob ntawm cov khoom siv abrasives thiab daim ntawv thov ntawm hydraulic tsav tau zoo heev rau kev txhim kho ntawmsib tsoo tshuab. Nrog rau txoj kev loj hlob ntawm kev lag luam niaj hnub, tshwj xeeb tshaj yog kev lag luam tsheb, ntau hom kev sib tsoo tshuab tau tuaj tawm ib qho tom qab. Piv txwv li, thaum pib ntawm lub xyoo pua 20th, lub ntiaj teb sab hauv grinder, crankshaft grinder, camshaft grinder thiab piston nplhaib grinder nrog lub tshuab nqus hlau nqus dej tau txuas ntxiv tsim los ua cov txheej txheem lub tog raj kheej.
Lub tshuab ntsuas tsis siv neeg tau siv rau lub tshuab sib tsoo hauv xyoo 1908. Nyob ib puag ncig xyoo 1920, lub tshuab tsis siv lub tshuab tsis siv neeg, ob chav kawg grinder, yob grinder, qhia kev tsheb nqaj hlau grinder, tshuab honing thiab super xov tshuab cuab yeej tau ua tiav thiab siv; Xyoo 1950, ahigh-precision cylindrical grinderrau daim iav sib tsoo tshwm sim; Thaum kawg ntawm xyoo 1960, cov tshuab sib tsoo high-speed nrog cov sib tsoo log linear ceev ntawm 60 ~ 80m / s thiab nto sib tsoo tshuab nrog loj txiav qhov tob thiab creep pub sib tsoo tshwm sim; Nyob rau xyoo 1970, kev tswj hwm digital thiab kev tswj hwm kev tswj hwm thev naus laus zis siv microprocessors tau siv dav hauv kev sib tsoo tshuab.
