Yimaphi amasayizi okusika atholakalayo?
Kunezilinganiso eziningana okufanele zicatshangelwe lapho ukhetha umsiki we-sprue. Lokhu kungase kuhlanganise ubude bayo yonke noma usayizi jikelele, ukujiya kwemihlathi, ububanzi bomhlathi, nobude bomhlathi. Zonke lezi zilinganiso zingaba nomthelela ekutheni i-sprue cutter ilungele izidingo zakho.
Ubude obuphelele bomsiki wesango ubude obusuka esihlokweni semihlathi kuya phansi kwesibambo. Lona ubukhulu bomsiki wesango ozocaciswa umenzi.Abasiki besango abaklanyelwe ukusika izinto ezithambile bangaba nobude obucishe bube ngu-120 mm (4¾ amayintshi) kuye ku-155 mm (amayintshi angu-6¼), kuyilapho abasiki abanokuxhuma okuyinkimbinkimbi banobude obucishe bube ngu-200 mm (8 amayintshi) ukuya ku-255 mm (10). amayintshi). ).Abasiki besprue abanobude obufushane obuphelele bafaneleka kangcono ukusebenza ngezihlahla eziminyene kanye nezingxenye ezincane ezintekenteke. Kodwa-ke, ubude obufushane busho amandla amancane futhi ngakho-ke amandla amancane okusika asetshenziswa emihlathini yalaba basiki besango, okubenza bangafaneleki ukusetshenziswa ezintweni eziqinile noma ezinzima.Abasiki besango abancane bavame ukuklanywa ukuthi basetshenziswe ngokunethezeka ngesandla esisodwa.Abasiki besango abakhulu, ngokuvamile abanokuxhumana okuyinkimbinkimbi, baklanyelwe ukusetshenziswa ngezandla ezimbili. Ubude babo obude bukhulisa amandla futhi ngakho-ke amandla okusika abangawasebenzisa. Lokhu kubenza bafaneleke kakhulu ukusika izinto eziwugqinsi neziqinile. Nokho, ubukhulu bawo obukhulu bubenza babe bulky. Lokhu, kuhlanganiswe nokusebenza kwezandla ezimbili, kubenza bangafaneleki umsebenzi obucayi noma ukususa izingxenye ezivela ku-sprue ogcwele ngokuqinile.Imihlathi emide ihlinzeka ngokufinyelela okukhulu ekubambeni nasekukhipheni izingxenye ezivela ku-sprue ominyene. Kodwa-ke, ikhono lokusika lemihlathi liyancipha kakhulu ngebanga ukusuka endaweni ye-pivot yemihlathi. Ngaleyo ndlela imihlathi emifushane izoba namandla engeziwe namandla okusika emaphethelweni emihlathi. Abasiki besango abancane banobude bemihlathi ukusuka cishe ku-8 mm (5/16″) kuya ku-16 mm (5/8″). Ubude bomhlathi babasiki abakhulu be-sprue buyahluka kancane, nemihlathi ngokuvamile iba ngu-20 mm (3/4 in.) ubude.Ugqinsi lwemihlathi lwabasiki be-sprue luyahlukahluka kuye ngobukhulu kanye nohlobo lwezinto ezihloselwe ukuzisika. Ngokungafani nobude obuphelele nobude bomhlathi, ukushuba komhlathi wokugezela akuvamile ukucaciswa, okungenza ukuqhathanisa kube nzima, ikakhulukazi uma kuqhathaniswa ku-inthanethi.Imihlathi ewugqinsi izoba namandla futhi izokwazi ukusika phakathi kwama-sprues aminyene noma ama-sprues enziwe ngezinto eziqinile. Kodwa-ke, imihlathi emikhulu ayikwazi ukungena ezindaweni okunzima ukufinyelela kuzo, ngakho-ke ayifaneleki ukususa izingxenye ezincane eziyinkimbinkimbi ku-sprue. Ngokuvamile, imihlathi emincane isetshenziswa kubasiki be-sprue besenzo esisodwa esihloselwe ukusetshenziswa ekwenziweni kwemodeli yepulasitiki, kuyilapho imihlathi eminyene isetshenziswa kubasiki be-sprue obuhlanganisiwe obuhloselwe ukusetshenziswa ubucwebe bensimbi.Ububanzi bomhlathi bomsiki wesango bulinganiswa ngebanga eliphakathi kwezinhlangothi zangaphandle zemihlathi emibili. Abasiki besprue abanobubanzi bemihlathi emikhulu bazoba nemihlathi eqinile efanelekela kangcono ukusika into ewugqinsi, eqinile. Nokho, abasiki bamasango abanama-swaths amakhulu ngeke bakwazi ukufinyelela futhi basuse izingxenye emasangweni aminyene noma izingxenye ezincane, ezintekenteke.
Ubude obuphelele
Ubude obuphelele bomsiki wesango ubude obusuka esihlokweni semihlathi kuya phansi kwesibambo. Lona ubukhulu bomsiki wesango ozocaciswa umenzi.
Abasiki besango abaklanyelwe ukusika izinto ezithambile bangaba nobude obucishe bube ngu-120 mm (4¾ amayintshi) kuye ku-155 mm (amayintshi angu-6¼), kuyilapho abasiki abanokuxhuma okuyinkimbinkimbi banobude obucishe bube ngu-200 mm (8 amayintshi) ukuya ku-255 mm (10). amayintshi). ).
Abasiki besprue abanobude obufushane obuphelele bafaneleka kangcono ukusebenza ngezihlahla eziminyene kanye nezingxenye ezincane ezintekenteke. Kodwa-ke, ubude obufushane busho amandla amancane futhi ngakho-ke amandla amancane okusika asetshenziswa emihlathini yalaba basiki besango, okubenza bangafaneleki ukusetshenziswa ezintweni eziqinile noma ezinzima.
Abasiki besango abancane bavame ukuklanywa ukuthi basetshenziswe ngokunethezeka ngesandla esisodwa.
Abasiki besango abakhulu, ngokuvamile abanokuxhumana okuyinkimbinkimbi, baklanyelwe ukusetshenziswa ngezandla ezimbili. Ubude babo obude bukhulisa amandla futhi ngakho-ke amandla okusika abangawasebenzisa. Lokhu kubenza bafaneleke kakhulu ukusika izinto eziwugqinsi neziqinile. Nokho, ubukhulu bawo obukhulu bubenza babe bulky. Lokhu, kuhlanganiswe nokusebenza kwezandla ezimbili, kubenza bangafaneleki umsebenzi obucayi noma ukususa izingxenye ezivela ku-sprue ogcwele ngokuqinile.Ubude bomhlathi
Imihlathi emide ihlinzeka ngokufinyelela okukhulu ekubambeni nasekukhipheni izingxenye ezivela ku-sprue ominyene. Kodwa-ke, ikhono lokusika lemihlathi liyancipha kakhulu ngebanga ukusuka endaweni ye-pivot yemihlathi. Ngaleyo ndlela imihlathi emifushane izoba namandla engeziwe namandla okusika emaphethelweni emihlathi. Abasiki besango abancane banobude bemihlathi ukusuka cishe ku-8 mm (5/16″) kuya ku-16 mm (5/8″). Ubude bomhlathi babasiki abakhulu be-sprue buyahluka kancane, nemihlathi ngokuvamile iba ngu-20 mm (3/4 in.) ubude.Ukuqina kwemihlathi
Ugqinsi lwemihlathi lwabasiki be-sprue luyahlukahluka kuye ngobukhulu kanye nohlobo lwezinto ezihloselwe ukuzisika. Ngokungafani nobude obuphelele nobude bomhlathi, ukushuba komhlathi wokugezela akuvamile ukucaciswa, okungenza ukuqhathanisa kube nzima, ikakhulukazi uma kuqhathaniswa ku-inthanethi.
Imihlathi ewugqinsi izoba namandla futhi izokwazi ukusika phakathi kwama-sprues aminyene noma ama-sprues enziwe ngezinto eziqinile. Kodwa-ke, imihlathi emikhulu ayikwazi ukungena ezindaweni okunzima ukufinyelela kuzo, ngakho-ke ayifaneleki ukususa izingxenye ezincane eziyinkimbinkimbi ku-sprue. Ngokuvamile, imihlathi emincane isetshenziswa kubasiki be-sprue besenzo esisodwa esihloselwe ukusetshenziswa ekwenziweni kwemodeli yepulasitiki, kuyilapho imihlathi eminyene isetshenziswa kubasiki be-sprue obuhlanganisiwe obuhloselwe ukusetshenziswa ubucwebe bensimbi.Ububanzi bomhlathi
Ububanzi bomhlathi bomsiki wesango bulinganiswa ngebanga eliphakathi kwezinhlangothi zangaphandle zemihlathi emibili. Abasiki besprue abanobubanzi bemihlathi emikhulu bazoba nemihlathi eqinile efanelekela kangcono ukusika into ewugqinsi, eqinile. Nokho, abasiki bamasango abanama-swaths amakhulu ngeke bakwazi ukufinyelela futhi basuse izingxenye emasangweni aminyene noma izingxenye ezincane, ezintekenteke.
