Mhando uye mashandisirwo emabhendi masaha

Mabhendi masaha akakamurwa kuita vertical and horizontal heavy type yekucheka matanda kuita mapuranga nematanda, zvepakati mhando vertical band masaha ekucheka matanda uye makobvu mabhodhi kuita matete uye akareruka emhando vertical band masaha ekucheka mapuranga akatwasuka uye akakombama nezvimwe zvinhu.

Nekubatsirwa kwebhandi masaha emhando inorema uye yepakati, kusiyana nemarara, matanda ega ega uye matanda anogona kutemwa mumapuranga, achifunga nezvekukanganisa uye mamwe maitiro ematanda. Mukuwedzera, kana vachicheka, vanopa hupamhi hudiki hwekucheka, saka huni hushoma hunopinda muhuni.

Mune basa rinoshanda remakambani muindasitiri yekuvaka yekugadzira huni, michina ine bhendi saws yemhando LC- yainyanya kushandiswa.70uye LC-80.

Mufananidzo 1 — Bhendi rakaona LC-80.

Muchina uyu une muviri, tafura inotenderedzwa, mavhiri maviri esaha — gidhi repasi uye repamusoro tensioner, bhureki mudziyo nemota yemagetsi.

Zvimiro zveunyanzvi LC-80

  • Diameter yemavhiri painoenda nebhendi: 800 mm
  • Kucheka upamhi - pfuura: 715 mm
  • Hurefu hwekucheka: 570 mm
  • Band saw hupamhi hweblade: kusvika 60 mm
  • Band saw blade kureba: 3600–6000 mm
  • Tafura dimension:945×970 mm
  • Diameter yevhiri rekutapurirana:285 mm
  • Nhamba yemavhiri revolutions paminiti:620-800 mm
  • Electric mota simba:3,2kW
  • Huremu hwemuchina:920 kg

Pamuchina uyu, mapuranga akakora anogona kutemwa kuita matete uchishandisa imwe nzira. Muchina uyu unocheka huni nebhendi resaha.
