Kev Txiav Tus Nqihais txog qhov ntau ntawm cov iav tsim nyog tom qab iav txiav ua ntej polishing.
Cov mis yog iav tsim nyog nrog qhov loj me xav tau x qhov ntev iav xav tau x qhov dav iav xav tau / qhov ntev iav nyoos / qhov dav iav nyoos = qhov nrawm txiav
Yog li thaum xub thawj, peb yuav tsum nkag siab meej txog qhov loj ntawm daim iav raw thiab pes tsawg millimeter (mm.) yuav tsum tseg rau qhov ntev thiab dav ntawm iav thaum txiav:
| Iav tuab (hli) | Cov Ntawv Iav Raw Txheem Loj (hli) | Millimeter yuav tsum tawm rau iav L. & W. (hli) |
| 0.25 | 1000 × 1200 | 0.1-0.3 |
| 0.4 | 1000 × 1500 | 0.1-0.3 |
| 0.55/0.7/1.1 | 1244.6 × 1092.2 | 0.1-0.3 |
| 1.0/1.1 | 1500 × 1900 | 0.1-0.5 |
| siab tshaj 2.0 | 1830 × 2440 | 0.5-1.0 |
| 3.0 thiab siab dua 3.0 | 1830 × 2400; 2440 × 3660 | 0.5-1.0 |
Piv txwv li:
| Qhov Loj Iav Yuav Tsum Tau | 454x131x4mm |
| Qhov Loj ntawm Daim Iav Raw Txheem | 1836x2440mm; 2440x3660mm |
| Millimeter yuav tsum tawm rau iav L. & W. (hli) | 0.5 hli rau txhua sab |
| Qhov Loj ntawm Cov Iav Raw | 1830 xyoo | 2440 | 1830 xyoo | 2440 |
| Yuav tsum tau iav loj nrog ntxiv mm thaum txiav | 454+0.5+0.5 | 131+0.5+0.5 | 131+0.5+0.5 | 454+0.5+0.5 |
| Qhov ntau tom qab daim ntawv nyoos faib los ntawm qhov loj me iav uas xav tau | 4.02 | 18.48 | 13.86 | 5.36 |
| Tag nrho cov iav tsim nyog qty | 4 × 18 = 72 daim | 13 × 5 = 65 daim | ||
| Kev Txiav Tus Nqi | 72x454x131/1830/2440=95% | 65x454x131/1830/2440=80% | ||
| Qhov Loj ntawm Cov Iav Raw | 2240 | 3360 | 2240 | 3360 |
| Yuav tsum tau iav loj nrog ntxiv mm thaum txiav | 454+0.5+0.5 | 131+0.5+0.5 | 131+0.5+0.5 | 454+0.5+0.5 |
| Qhov ntau tom qab daim ntawv nyoos faib los ntawm qhov loj me iav uas xav tau | 4.92 | 25.45 | 16.97 | 7.38 |
| Tag nrho cov iav tsim nyog qty | 4 × 25 = 100 daim | 16 × 7 = 112 daim | ||
| Kev Txiav Tus Nqi | 100x454x131/2440/3660=66% | 112x454x131/2440/3660=75% | ||
Yog li ntawd, peb tau paub meej tias, 1830x2440mm raw sheet yog thawj qhov kev xaiv thaum txiav.
Koj puas muaj lub tswv yim yuav ua li cas suav tus nqi txiav?
