Machining tus nqi kwv yees yog ib kauj ruam tseem ceeb.Qhov tseeb ntawm machining tus nqi txheeb cais yuav cuam tshuam ncaj qha rau kev ua, kev tsim khoom thiab kev muag khoom, uas yog qhov tseem ceeb tshaj plaws.Dab tsi yog tus nqi suav nrog
1.Material cost: cov nqi khoom siv, cov nqi thauj khoom, cov nqi mus txawv tebchaws tshwm sim thaum cov txheej txheem yuav khoom, thiab lwm yam;
2.Cov nqi ua haujlwm: cov sijhawm ua haujlwm ntawm txhua tus txheej txheem, cov khoom siv depreciation, dej thiab hluav taws xob, cov cuab yeej, cov cuab yeej, ntsuas cov cuab yeej, cov khoom siv pabcuam, thiab lwm yam.
3. Kev tswj cov nuj nqis: amortization of fixed cost, amortization of management staff wages, site fees, travelling, etc.
4. Cov se: se teb chaws, se hauv zos;
5.Profit
Txoj kev suav nqi
Xam cov nqi ua raws li qhov ntau, qhov loj thiab qhov tseeb ntawm cov khoom
1.Yog qhov aperture piv tsis ntau tshaj 2.5 npaug thiab txoj kab uas hla yog tsawg dua 25MM, nws yog xam raws li lub laum txoj kab uas hla * 0.5
2.Cov qauv them nyiaj rau cov khoom siv dav dav nrog qhov sib piv ntawm qhov tob-rau-inch siab dua 2.5 yog xam raws qhov tob-rau-inch piv * 0.4
3. Tshuab dhos ua
Yog hais tias lub machining ntev txoj kab uas hla ntawm lub dav dav precision optical axis tsis ntau tshaj 10, nws yog xam raws li lub workpiece dawb paug loj * 0.2.
Yog hais tias tus nam piv yog ntau tshaj 10, lub hauv paus nqi ntawm lub dav optical axis * nam piv * 0.15
Yog hais tias qhov yuav tsum tau muaj yog nyob rau hauv 0.05MM los yog taper yuav tsum tau, nws yuav tsum tau xam raws li lub hauv paus nqi ntawm lub dav optical axis * 2.
Txheej txheem nqi accounting
1.Nws yuav tsum suav nrog cov nqi ntawm cov khoom siv, cov nqi ua haujlwm, cov nqi txo cov khoom siv, cov nyiaj ua haujlwm, cov nqi tswj, se, thiab lwm yam.
2. Thawj kauj ruam yog txhawm rau txheeb xyuas cov txheej txheem ua haujlwm, thiab tom qab ntawd suav cov sijhawm ua haujlwm raws li cov txheej txheem, suav cov nqi ua haujlwm yooj yim thiab lwm yam nqi ntawm ib feem ntawm lub sijhawm ua haujlwm.Ib feem txais cov txheej txheem sib txawv, thiab tus nqi sib txawv heev.
3.Lub sijhawm ua haujlwm ntawm ntau hom kev ua haujlwm tsis raug kho.Nws yuav txawv raws li qhov nyuaj ntawm lub workpiece, qhov loj thiab kev ua haujlwm ntawm cov khoom siv.Ntawm chav kawm, qhov no kuj nyob ntawm qhov ntau ntawm cov khoom.qhov loj dua qhov ntau, tus nqi pheej yig dua.
Kev paub yooj yim ntawm machining raug ntawm cov khoom siv tshuab
Machining raug yog hais txog cov degree uas qhov loj me, cov duab, thiab txoj hauj lwm ntawm qhov chaw ntawm lub tshuab ua tau raws li qhov zoo tshaj plaws geometric tsis xav tau los ntawm daim duab.Qhov zoo tagnrho geometric parameter yog qhov nruab nrab loj;rau qhov chaw geometry, nws yog lub voj voog meej, lub tog raj kheej, dav hlau, lub khob hliav qab thiab kab ncaj nraim, thiab lwm yam;rau qhov kev sib nrig sib ntawm qhov chaw, muaj qhov tsis sib xws, perpendicularity, coaxiality, symmetry, thiab lwm yam. Qhov sib txawv ntawm qhov tseeb geometric tsis ntawm ib feem thiab qhov zoo tagnrho geometric tsis yog hu ua machining yuam kev.
