Zozungulira macheka masamba ali angapo zigawo za mitundu yosiyanasiyana, ndi ubwino ndi kuipa kwa aliyense.
Kusankha mitundu ya macheka ozungulira;Mitundu yomwe imagwiritsidwa ntchito kwambiri ya simenti ya carbide ndi tungsten-cobalt (code YG) ndi tungsten-titanium (code YT).Chifukwa cha kukana kwabwino kwa tungsten ndi cobalt carbides, amagwiritsidwa ntchito kwambiri pamakampani opanga matabwa.Mitundu yomwe imagwiritsidwa ntchito kwambiri pokonza matabwa ndi YG8-YG15.Nambala pambuyo pa YG ikuwonetsa kuchuluka kwa cobalt.Ndi kuchuluka kwa cobalt, kulimba kwamphamvu ndi kusinthasintha kwa aloyi kumatheka, koma kulimba ndi kukana kuvala kumachepa.Sankhani malinga ndi momwe zinthu zilili.
1. 65Mn kasupe zitsulo ali elasticity wabwino ndi plasticity, chuma chuma, zabwino kutentha kutentha hardability, otsika kutentha kutentha, mapindikidwe mosavuta, ndipo angagwiritsidwe ntchito masamba macheka amene safuna mkulu kudula zofunika.
2. Chitsulo cha carbon chida chimakhala ndi mpweya wambiri komanso kutentha kwapamwamba, koma kuuma kwake ndi kuvala kukana kumatsika kwambiri pamene kutentha kwa 200 ℃-250 ℃, kutentha kwa kutentha kumakhala kwakukulu, kuuma kwake kumakhala kosauka, komanso nthawi yowonongeka. ndi yayitali komanso yosavuta kusweka.Pangani zida zachuma zodulira zida monga T8A, T10A, T12A, etc.
3. Poyerekeza ndi carbon chida zitsulo, aloyi chida zitsulo ali wabwino kukana kutentha, kuvala kukana ndi bwino akugwira ntchito.Kutentha kosokoneza kutentha ndi 300 ℃-400 ℃, komwe kuli koyenera kupanga masamba ozungulira a aloyi apamwamba kwambiri.
4. Chitsulo chachitsulo chothamanga kwambiri chimakhala ndi kuuma kwabwino, kuuma kwamphamvu ndi kukhazikika, komanso kusinthika kochepa kosamva kutentha.Ndichitsulo cholimba kwambiri chokhala ndi thermoplasticity yokhazikika ndipo ndi yoyenera kupanga macheka apamwamba kwambiri.
Kutalika kwa macheka ozungulira;kutalika kwa tsamba la macheka kumayenderana ndi zida zocheka zomwe zimagwiritsidwa ntchito komanso makulidwe a chogwirira ntchito.Kutalika kwa tsamba la macheka ndi kakang'ono, ndipo liwiro lodula ndilochepa;kukula kwake kwa tsamba la macheka, kumapangitsanso kuti macheka apangidwe ndi zipangizo zocheka ndi apamwamba, komanso kukweza kwa macheka.Kuzungulira kwakunja kwa tsamba la macheka kumasankhidwa molingana ndi mitundu yozungulira yozungulira ndipo tsamba lokhala ndi mainchesi omwewo limagwiritsidwa ntchito.
The diameters wa mbali muyezo ndi: 110MM (4 mainchesi), 150MM (6 mainchesi), 180MM (7 mainchesi), 200MM (8 mainchesi), 230MM (9 mainchesi), 250MM (10 mainchesi), 300MM (12 mainchesi), 350MM ( mainchesi 14), 400MM (16 mainchesi), 450MM (18 mainchesi), 500MM (20 mainchesi), etc. Pansi poyambira anawona masamba a mwatsatanetsatane gulu macheka makamaka anakonza kukhala 120MM.
Kusankhidwa kwa chiwerengero cha mano a macheka ozungulira;chiwerengero cha mano a macheka mano, ambiri kulankhula, mano kwambiri, m'mphepete kwambiri kudula akhoza kudula pa unit nthawi, ndi bwino kudula ntchito, koma chiwerengero cha kudula mano amafuna carbide kwambiri, ndi mtengo wa macheka. tsamba Komabe, ngati chekalo ndi wandiweyani kwambiri, mphamvu ya chip pakati pa mano imakhala yaying'ono, yomwe imapangitsa kuti tsamba la macheka litenthe;kuonjezera apo, ngati pali macheka ochuluka kwambiri, ngati mlingo wa chakudya sunagwirizane bwino, chiwerengero chodula cha dzino lililonse chimakhala chochepa kwambiri, chomwe chidzakulitsa chigawo chodula ndi chogwirira ntchito.Kukangana kumakhudza moyo wautumiki wa tsamba.Nthawi zambiri malo otalikirana ndi mano ndi 15-25mm, ndipo mano oyenerera ayenera kusankhidwa molingana ndi zomwe acheke.
Kukhuthala kwa macheka ozungulira;makulidwe a tsamba la macheka M'lingaliro, tikuyembekeza kuti kuonda kwa tsamba la macheka, bwino, msoko wa macheka kwenikweni ndi mtundu wakumwa.Zida za alloy saw blade base komanso kupanga macheka kumatsimikizira makulidwe a tsamba la macheka.Ngati makulidwewo ndi ochepa kwambiri, tsamba la macheka ndilosavuta kugwedezeka pamene likugwira ntchito, zomwe zimakhudza kudula.Posankha makulidwe a tsamba la macheka, kukhazikika kwa tsamba la macheka ndi zinthu zomwe ziyenera kudulidwa ziyenera kuganiziridwa.Kunenepa komwe kumafunikira pazida zina zapadera ndikokhazikikanso, ndipo kuyenera kugwiritsidwa ntchito molingana ndi zofunikira za zida, monga ma slotting macheka, macheka a scribing, ndi zina zambiri.
1. Mawonekedwe a dzino omwe amagwiritsidwa ntchito kwambiri ndi mano akumanzere ndi akumanja (mano osinthika), mano osalala, mano amtundu wa trapezoidal (mano apamwamba ndi otsika), mano opindika a trapezoidal (mano opindika), mano a dovetail (mano a hump), ndi mafakitale osowa. kalasi lachitatu kumanzere ndi mano amodzi kumanja, kumanzere ndi kumanja athyathyathya, etc.
2. Macheka a dzino lathyathyathya ndi ovuta, liwiro lodula ndilochedwa, ndipo kugaya ndikosavuta.Amagwiritsidwa ntchito kwambiri pocheka matabwa wamba, ndipo mtengo wake ndi wotsika.Amagwiritsidwa ntchito kwambiri popanga zitsulo za aluminiyamu zokhala ndi mainchesi ang'onoang'ono kuti achepetse kumamatira panthawi yodula, kapena ngati ma grooving macheka kuti pansi pake pakhale pompopompo.
3. Makwerero lathyathyathya dzino ndi osakaniza trapezoidal dzino ndi lathyathyathya dzino.Kupera kumakhala kovuta kwambiri.Mukamacheka, zimatha kuchepetsa kusweka kwa veneer.Ndi yoyenera kucheka mapanelo osiyanasiyana amtundu umodzi komanso wawiri wamatabwa komanso mapanelo osayaka moto.Pofuna kupewa kumamatira masamba a aluminiyamu, masamba ocheka okhala ndi mano osalala amagwiritsidwa ntchito nthawi zambiri.
4. Mano otembenuzidwa makwerero nthawi zambiri amagwiritsidwa ntchito pa tsamba la pansi pa macheka a macheka.Pamene ankaona wapawiri-veneer matabwa ofotokoza gulu, poyambira anawona amasintha makulidwe kuti amalize grooving ndondomeko pansi pamwamba, ndiyeno waukulu macheka wamaliza macheka ndondomeko ya bolodi, kuti Kupewa macheka m'mphepete kwa chipping.
