Mtundu wa ZT Casing Drilling bit, Reaming Wotopetsa Mutu
Mafotokozedwe Akatundu
Casing Drilling bit imatchedwanso kuti kubowola kwa annular, ndi njira yachuma, yopindulitsa komanso yapamwamba kwambiri.Ndi bwino kugwiritsa ntchito pobowola pobowola pobowola bowo pamwamba pa 50mm m'mimba mwake.
(1) dzenje m'mimba mwake ndi 50mm pamwamba, ndi kulolerana pafupi kuwongoka ndi malo mwatsatanetsatane
(2) Chiyerekezo chautali ndi m'mimba mwake cha dzenje chimakhala cha 1 ~ 75, ndiye chisankho chabwino kugwiritsa ntchito pobowola mutu kuposa njira zina zamachining.
(3) Zopangira ntchito ndizokwera mtengo kwambiri ndipo maziko ake amafunikira kuyeza ndi kusanthula mankhwala, ndipo mandrel onse apakati ayenera kusungidwa.
(4) Mphamvu yamakina sikokwanira ngati kubowola dzenje lalikulu, ndiye kuti trepanning ndiye chisankho chabwino.Ndi yoyenera m'mimba mwake kuyambira 50 mpaka 600mm (zida zofananira ziyenera kuyikidwanso).
| AYI. | Mavuto | Chifukwa | Yankho |
| 1 | Machining chip ndi ochepa kwambiri | zolakwika kudula deta
| Sinthani Liwiro ndi Chakudya |
| Ma geometry olakwika a chip, ellipse angle yaying'ono kwambiri kapena yakuya kwambiri
| Sinthani mitundu yodula kwambiri | ||
| Kusakhazikika kwazinthu zogwirira ntchito | Sinthani Liwiro ndi Chakudya | ||
| Kudulira koyambirira koyipa (chogwirira ntchito sichinakhazikike) | Position hole center | ||
| 2 | Machining chip ndi chachikulu kwambiri | zolakwika kudula deta | Sinthani Liwiro ndi Chakudya |
| Ma geometry olakwika a chip, ellipse angle yaying'ono kwambiri kapena yakuya kwambiri | Sinthani mitundu yodula kwambiri | ||
| 3 | Machining chips si ofanana | Zida zogwirira ntchito sizofanana | Sinthani mitundu yodula kwambiri |
| Njira yolakwika yodyetsera (hydraulic feeding) | Yang'anani ndi wopanga | ||
| Kuziziritsa sikwabwino | Konzani kuziziritsa kwakukulu | ||
| Kugwedezeka kwamphamvu komwe kumachitika chifukwa chakusakhazikika kwa chogwirira ntchito ndi chida Zomwe zimagwirira ntchito ndizosakhazikika. | Yang'anani ndi wopanga | ||
| 4 | Zitsanzo zazitsulo za fiber | Zida zogwirira ntchito sizofanana | Sinthani mitundu yodula kwambiri |
| Njira yolakwika yodyetsera (hydraulic feeding) | Yang'anani ndi wopanga | ||
| Madzi ozizira osakwanira | Choziziritsa kuyeretsa | ||
| Chemical affinity reaction pakati pa workpiece ndi carbide chida | kusintha | ||
| chip m'mphepete | kusintha | ||
| chakudya chochepa kwambiri | Konzani kadyedwe | ||
| 5 | Kudulidwa kwa zoyikapo simenti za carbide | Wodula si wachangu | Sinthani |
| Coolant sikugwira ntchito bwino | Onani kuthamanga ndi kuthamanga | ||
| Madzi ozizira osakwanira | Onani zoziziritsa kukhosi | ||
| Kulekerera kwa bushing ndikwang'ono kwambiri | Sinthani | ||
| Bowola ndi spindle ndi eccentric | Sinthani kukhala eccentric | ||
| Cholakwika chodula chizindikiro | Sinthani | ||
| Zida zogwirira ntchito sizokhazikika | Khazikitsani liwiro ndi chakudya choyenera |
