Kev kho kev ntxhov siab yog ua ua ntej kev kho cua sov tom qab machining. Feem ntau, aluminium alloys yog quenched ntawm HRC45 ± 1 degree, thiab zinc alloys ntawm HRC46 ± 1-1 degree.
Sab hauv pwm haum rau kev kam rau siab: Feem ntau, nws yuav tsum yog kwv yees li 0.05-0.08mm me dua li cov pwm pwm, tso cai rau kev tshem tawm yooj yim thiab tso rau hauv cov pwm siv lifting rings.
Ejector pin haum kam rau ua: 0.05mm rau ejector pins Ntau tshaj los yog sib npaug rau 8mm inch,
0.025mm rau ejector pins Tsawg dua los yog sib npaug rau 6mm inch.
Tag nrho cov kaum sab xis thiab cov kaum sab xis ntawm cov pwm sab hauv yuav tsum muaj lub vojvoog ntawm tsawg kawg yog 0.5 hli.
Tshaj qhov ntawm lub puab puab nto yuav tsum tau muab kaw nrog flathead screws.
