Iikhrayitheriya zokukhetha iiparamitha zeesarha zedayimane

1. Ukukhethwa kobungakanani besuntswana ledayimane
Xa ubungakanani bedayimani burhabaxa kwaye bungatshatanga, intloko yeblade ibukhali kwaye ukusika kuphezulu, kodwa amandla okugoba e-diamond agglomeration ayancipha.Xa igranularity yedayimani ilungile okanye ixubene, intloko yeblade yesarha inokuqina okuphezulu kodwa ukusebenza kakuhle okuphantsi.Ukuqwalasela le miba ingentla, i-50/60 ye-diamond ye-mesh ifanelekile.
2. Ukukhethwa koxinaniso lokusasazwa kwedayimani
Kuluhlu oluthile, xa ugxininiso lwedayimane lutshintsha ukusuka kwi-low ukuya phezulu, ubukhali kunye nokusebenza kakuhle kwe-saw blade kuncipha ngokuthe ngcembe, kodwa ubomi benkonzo buyanda ngokuthe ngcembe.Kodwa ukuba ugxininiso luphezulu kakhulu, i-blade iya kuba buthuntu.Ukusebenzisa ugxininiso oluphantsi, ubungakanani bengqolowa oburhabaxa, ukusebenza kakuhle kuya kuphuculwa.Ukusetyenziswa kwamacandelo ahlukeneyo entloko yesixhobo kwi-sawing, usebenzisa i-concentrations ehlukeneyo (oko kukuthi, kwimigangatho emithathu okanye ngaphezulu kwesakhiwo somgangatho ophakathi kungasetyenziselwa ukuxinzelela phantsi), inkqubo ye-saw head work on the formation. I-groove ephakathi, inceda ukukhusela i-saw blade pendulum, ukuze kuphuculwe umgangatho wokulungiswa kwamatye.
3. Ukukhethwa kwamandla edayimani
Amandla edayimani yisalathisi esibalulekileyo sokuqinisekisa ukusebenza kokusika.Amandla aphezulu kakhulu aya kwenza ukuba i-crystal ingabi lula ukuphuka, iinqununu ze-abrasive ziphuculwe ekusebenziseni, ubukhali buyancipha, obukhokelela ekudakaleni kwesixhobo;Xa amandla edayimani ayanele, kulula ukuphulwa emva kwempembelelo kwaye kunzima ukuthwala umsebenzi onzima wokusika.Ke ngoko, ukuqina kufuneka kukhethwe kwi-130 ~ 140N.4. Ukukhethwa kwesigaba sokudibanisa
Ukusebenza kwe-saw blade akuxhomekanga kuphela kwidayimane, kodwa nakwintsebenzo yonke yezinto ezidibeneyo ezenziwe ngokudibanisa okufanelekileyo kwedayimane kunye ne-binder.Kwi-marble kunye namanye amatye athambileyo, iipropathi zoomatshini zentloko yesixhobo ziphantsi ngokwentelekiso, zingakhetha i-copper base binder.Kodwa ubushushu be-sintering ye-copper base binder buphantsi, amandla kunye nokuqina kuphantsi, ukuqina kuphezulu, kwaye amandla okudibanisa nedayimani aphantsi.Xa i-WC yongezwa, i-WC okanye i-W2C isetyenziswe njengesinyithi se-skeleton, kunye nesixa esifanelekileyo se-cobalt ukuphucula amandla, ubunzima kunye neempawu zokubopha, kunye nexabiso elincinci le-Cu, i-Sn, i-Zn kunye nezinye izinyithi ezinendawo ephantsi yokunyibilika kunye nobunzima. yongezwe njengesigaba sokudibanisa.Ubungakanani beqhekeza lenqununu yenqununu yezongezo kufuneka ibe bhetele kune-mesh ye-200, kunye ne-particle size ye-additive component kufuneka ibe yincinci kune-300 mesh.
5. Ukukhethwa kwenkqubo ye-sintering
Ngokunyuka kweqondo lokushisa, iqondo lokuxinana kwe-carcass liyanda, ngokunjalo namandla okugoba.Nangona kunjalo, ngokongezwa kwexesha lokubamba, amandla okugoba kwe-carcass engenanto kunye ne-diamond agglomeration kuqala yonyuka kwaye emva koko iyancipha.Inkqubo ye-sintering ye-120s kwi-800 ℃ ingakhethwa ukuhlangabezana neemfuno zokusebenza.
