Cov txheej txheem ntawm tig tshuab dhos

1. Rough tig yog qhov kev lag luam zoo tshaj plaws rau kev ua haujlwm ntxhib ntawm cov voj voog sab nrauv. Vim lub hom phiaj tseem ceeb ntawm kev txiav ntxhib yog kom tshem tawm cov hlau ntau dhau ntawm qhov khoob, kev txhim kho cov khoom lag luam yog nws txoj haujlwm tseem ceeb.
Rough tig feem ntau siv qhov siab tshaj plaws rov qab txiav thiab pub tus nqi los txhim kho cov khoom tsim tau. Txhawm rau kom ntseeg tau tias cov cuab yeej tsim nyog lub neej, kev txiav ceev feem ntau qis dua. Thaum txoj kev ntxhib, lub kaum sab xis loj dua yuav tsum raug xaiv rau lub cuab yeej tig kom txo qis rov qab quab yuam thiab tiv thaiv kev khoov deformation thiab kev co ntawm lub workpiece; Xaiv cov kaum sab xis me me rau pem hauv ntej thiab nraub qaum, nrog rau qhov tsis zoo ntawm cov hniav inclination lub kaum sab xis, txhawm rau txhim kho lub zog ntawm qhov txiav ntawm cov cuab yeej tig. Qhov tseeb machining uas ntxhib tig tuaj yeem ua tiav yog IT12 ~ ITll, thiab qhov roughness Ra yog 50 ~ 12.5 μ m.
Lub luag haujlwm tseem ceeb ntawm precision machining yog los xyuas kom meej qhov xav tau machining raug thiab qhov zoo ntawm qhov chaw. Qhov saum npoo ntawm precision tig lub voj voog sab nrauv feem ntau ua tiav siv cov khoom me me rov qab thiab pub tus nqi, nrog rau kev txiav nrawm dua. Thaum ua tiav lub voj voog sab nraud ntawm cov ncej loj, cov cuab yeej siv dav dav feem ntau siv rau kev ua kom qis qis. Thaum precision tig, loj dua pem hauv ntej thiab nram qab lub kaum sab xis, nrog rau cov cuab yeej zoo, yuav tsum tau xaiv rau cov cuab yeej tig los txhim kho qhov zoo ntawm cov machining. Precision machining tuaj yeem siv los ua qhov kawg machining ntawm high-precision txheej txheej los yog ua ntej machining rau precision machining. Lub machining raug ntawm precision tig tuaj yeem ncav cuag IT8 rau IT6 qib, thiab qhov roughness ntawm Ra tuaj yeem ncav cuag 1.6 txog 0.8 μ m.
3. Cov yam ntxwv ntawm precision tig yog: qhov kev txiav rov qab thiab cov khoom noj muaj tsawg heev, thiab kev txiav ceev tuaj yeem ncav cuag li 150-2000m / min. Cov tsheb zoo feem ntau ua tiav siv cov khoom siv superhard xws li cubic boron nitride (CBN) thiab pob zeb diamond. Lub tshuab cuab yeej siv yuav tsum yog cov cuab yeej ua haujlwm siab lossis cov cuab yeej siv lub tshuab nrog lub spindle muaj peev xwm ntawm kev sib hloov ceev thiab siab nruj. Lub machining raug thiab nto roughness ntawm precision tig yog feem ntau sib npaug rau cov cylindrical sib tsoo zoo tib yam, nrog ib tug machining raug ntawm IT6 los yog saum toj no thiab ib tug nto roughness Ra ntawm 0.4-0.005 μ m. Nws yog feem ntau siv rau precision machining ntawm non-ferrous hlau workpieces nrog kev sib tsoo tsis zoo. Rau workpieces xws li txhuas thiab txhuas alloys uas nquag mus clogging lub sib tsoo log pores, precision machining yog zoo dua. Fine tig tuaj yeem hloov kev sib tsoo thaum ua cov txheej txheem loj ntawm qhov chaw ncig.
