I-Tungsten Carbide vs iSpeed-Speed Steel: Umboniso oGqibeleleyo wokuSila izixhobo zeQuill

Kwintsimi yokugaya ngokuchanekileyo, ukukhethwa kwezinto zokugaya i-quill kuchaphazela ngokuthe ngqo umgangatho womatshini kunye nokusebenza kakuhle. I-Carbide kunye ne-high-speed steel (HSS), njengezinto ezimbini eziqhelekileyo, nganye ibonisa iimpawu zokusebenza ezizodwa, idala "umboniso wokugqibela" othakazelisayo.

Uthelekiso lokuSebenza kwezinto eziphathekayo 

I-Tungsten carbide, ngokuyinhloko yenziwe nge-tungsten carbide ene-cobalt njenge-binder, ifezekisa ubulukhuni be-HRA 88-93, i-modulus elastic ukuya kwi-600 GPa, kunye namandla acinezelayo angaphezu kwe-4,000 MPa. Xa kuthelekiswa, i-HSS idla ngokuba nobulukhuni be-HRC 63-67, imodyuli elastiki emalunga nama-200 GPa, kunye namandla acinezelayo amalunga ne-2,500 MPa. Ezi mpawu zisisiseko zinika i-carbide inzuzo ekuqineni kunye nokumelana nokunxiba.

Ukwenziwa kweSicelo esiSebenzayo 

Kwizicelo ezinobude bobude ukuya kububanzi obudlula i-4: 1, iintsiba zokusila i-carbide zibonisa iinzuzo ezingenakubuyiselwa. Imodyuli enwebekayo ephezulu iqinisekisa ukuba, phantsi kweemeko ezifanayo zomthwalo, ukuphambuka sisinye kwisithathu kuphela se-HSS. Oku kubalulekile ekusileni umngxuma onzulu kunye nokuchaneka kwangaphakathi kwe-cylindrical grilling. Uvavanyo olusebenzayo lubonisa ukuba xa imingxuma yomatshini ingaphantsi kwe-150 mm, iiquill ze-carbide zinokugcina iimpazamo ezingqukuva ngaphakathi kwe-0.005 mm, ngelixa iiquill ze-HSS zihlala zibonisa ukutenxa okudlula i-0.02 mm.

Uhlalutyo lwezoQoqosho 

Nangona ixabiso lokuqala lokuthengwa kwee-quill zevili lokusila i-carbide liphezulu ngamaxesha angama-3-5 ngaphezu kwe-HSS wheel quills, ubomi babo benkonzo buhlala amaxesha angama-10-15 ubude. Ngokomzekelo, kumgca wokuvelisa i-automotive parts, ukutshintshela kwi-carbide quills ukwandisa ixesha lokutshintsha isixhobo ukusuka kwiiyure ze-8 ukuya kwiiyure ze-120 kunye nokunciphisa izinga lesiphene semveliso ukusuka kwi-3% ukuya kwi-0.5%. Ukuthathela ingqalelo ixesha lokuphumla, iindleko zabasebenzi, kunye namazinga okulahla, i-carbide ibonelela ngokubaluleke kakhulu ukusebenza kakuhle kwezoqoqosho.

Iingcebiso zemeko yeSicelo 

Iintsiba zokusila ze-HSS zisabambe izibonelelo kwiindawo ezithile:  

1. Kwi-batch encinci, imveliso eguquguqukayo ephezulu, apho iindleko zotyalo-mali eziphantsi zibaluleke kakhulu.  

2. Xa umatshini ezinye izinto ezinzima ezithambekele kwi-edge eyakhelwe-up, i-HSS inikezela ngeempawu ezingcono zokuchasana.  

3. Kwizicelo ezintsonkothileyo zokugaya iprofayili, i-HSS ilula ukwenza umatshini kwiimilo ezikhethekileyo.

IiNdlela zoPhuhliso lwexesha elizayo  

Ngokuvela kwe-nano-grained carbide kunye nezinto ezisebenzayo ze-gradient, ukusebenza kwe-carbide kuyaqhubeka nokuphucula. Ngeli xesha, i-HSS igcina ukukhuphisana kwayo kwimimandla ethile ngokusebenzisa itekhnoloji yomgubo wesinyithi kunye neenkqubo zokwambathisa ezihambele phambili. Zombini izixhobo ziya kuhlala kunye kwaye ziphuhlise ngokuhambelana kwikamva elibonakalayo, kodwa ubukhosi be-carbide kwi-high-end precision machining iya kuqhubeka isomeleza.

Ukukhetha izinto ezifanelekileyo zokusila i-shaft kufuna uqwalaselo olucokisekileyo lweemfuno zoomatshini, umthamo wemveliso, kunye nohlahlo lwabiwo-mali. Kwimveliso yanamhlanje, ukulandela ukuchaneka okuphezulu kunye nokusebenza kakuhle, i-carbide ngokungathandabuzekiyo lolona tyalo-mali lunexabiso.
