1. Cov khoom siv raw ntawm lub pob ntsia hlau yog rub los ntawm cov pwm mus rau qhov xav tau nruab nrab txoj kab uas hla, thiab qhov tawv tawv (0.5 hli) ncav cuag (18 degrees -21} degrees) los ntawm thib ob txias duab.
2. Qib precision ntawm cov ntsia hlau txhuas yuav tsum ncav cuag: 3-4.
3. Cov khoom siv raw ntawm cov ntsia hlau txias dov txheej txheem yog ncaj thiab dov, thiab qhov tawv tawv (0.5 hli) ncav cuag 22 degrees.
4. Cov ntsia hlau txhuas yog kho nrog nyuaj chrome, polished thiab ncaj ua ntej tawm hauv lub hoobkas.
Cov ntsia hlau ntsia hlau yog nyias thiab hloov tau ntev, thiab nws cov nam piv feem ntau loj heev, feem ntau nyob ib ncig ntawm 20-50, thiab nws cov rigidity tsis zoo heev. Tsis tas li ntawd, nws cov qauv thiab cov duab yog qhov nyuaj, nrog rau qhov xav tau heev threaded nto, nrog rau cov kauj ruam thiab grooves. Yog li ntawd, cov ntsia hlau loj loj yog feem ntau deformation thaum lub sij hawm machining txheej txheem. Qhov no yog qhov tsis sib xws loj uas cuam tshuam rau qhov tseeb hauv cov ntsia hlau machining. Lub ntsiab kev xav tau kev pab:
1. Dimensional precision Cov ntawv xov xwm yog lub ntsiab ntawm qhov chaw ntawm cov ncej, uas cuam tshuam rau kev sib hloov qhov tseeb thiab kev ua haujlwm ntawm cov ncej. Txoj kab uas hla qhov tseeb ntawm phau ntawv journal feem ntau yog IT 6-9 raws li nws cov kev xav tau siv, thiab cov ntawv xov xwm precision tuaj yeem ncav cuag IT5.
2. Geometric shape accuracy Lub geometric duab raug (roundness, cylindricity) ntawm phau ntawv journal feem ntau yuav tsum tau txwv rau ntau yam ntawm txoj kab uas hla kam rau siab point. Thaum cov ntsia hlau ntsia hlau sab saud muaj qhov yuav tsum tau ua rau qhov tseeb geometric, qhov kev tso cai ntev tuaj yeem raug cais tawm ntawm qhov kos duab. 3. Qhov tseeb ntawm txoj hauj lwm feem ntau yog hais txog lub coaxiality ntawm cov ntawv xov xwm sib txuam ntawm kev sib txuas lus sib txuas nrog cov ntawv xov xwm txhawb nqa ntawm cov kabmob sib dhos, uas feem ntau yog qhia los ntawm radial runout ntawm phau ntawv txhawb nqa mus rau phau ntawv txhawb nqa; Raws li qhov yuav tsum tau ua ntawm kev siv, Lub siab precision axis yog teev raws li 0.001-0.005mm, thiab dav dav precision axis yog 0.01-0.03mm.
