Xa iinjineli kunye nabathengi bechaza i-DIN 333 center drill, omnye wemibuzo eqhelekileyo esiyifumanayo ngulo: "Yintoni umahluko phakathi kohlobo A kunye nohlobo B — kwaye loluphi endiludingayo ngokwenene?"
Ngumbuzo ofanelekileyo. Zombini ezi ntlobo zine-engile efanayo ye-chamfer engama-60°, zilandela umgangatho ofanayo we-DIN 333, kwaye ziyafumaneka kwizixhobo ezifanayo. Kodwa kukho umahluko obalulekileyo wejometri phakathi kwazo — lowo unefuthe ngqo kwindlela umngxuma wakho osembindini ohlala ngayo kwinkqubo yokugaya.
Esi sikhokelo sichaza umahluko ngokucacileyo, ngeetafile zobukhulu be-DIN 333 kuzo zombini ezi ntlobo.
Yintoni i-DIN 333 Center Drill?
I-drill esembindini — ekwabizwa ngokuba yi-drill edibeneyo kunye ne-countersink — isetyenziselwa ukwenza umngxuma ochanekileyo we-60° ekhonkrithi ekupheleni kwento yokusebenza ngaphambi kokuba ujike phakathi kwamaziko nge-lathe. Umngxuma osembindini ubonelela ngendawo yokuhlala ezinzileyo yeziko le-tailstock, ukuqinisekisa ukuqina kunye nokuchaneka kwendawo kuyo yonke imisebenzi elandelayo yokujika, ukugaya, okanye yokugaya.
I-DIN 333 ngumgangatho waseJamani (i-Deutsche Institut für Normung) olawula ijometri, ubukhulu, kunye nokunyamezelana kweedrili eziphakathi ezingama-60°. Ichaza iintlobo ezintathu: Uhlobo A, Uhlobo B, kunye nohlobo R. Eli nqaku ligxile kwiintlobo ezimbini ezichazwe rhoqo: u-A kunye no-B.

Ukhetho lwezinto: M2 vs. M35
Zombini iidrili zeziko zohlobo A kunye nohlobo B ziyafumaneka kwiindidi ezimbini ze-HSS. Ukukhetha izinto akuxhomekekanga kuhlobo — kuxhomekeke kwizinto zokusebenza kunye nomthamo wemveliso.
I-M2 HSS — Udidi oluqhelekileyo
I-M2 (HS6-5-2) yeyona nqanaba le-HSS esetyenziswa kakhulu kwihlabathi liphela. Inika ukuqina okuhle, ukumelana nokuguguleka okuthembekileyo, kunye nokusebenza rhoqo kuluhlu olubanzi lwezixhobo zokusebenza - intsimbi ethambileyo, i-aluminium, isinyithi esityhidiweyo, ubhedu, kunye nezinye iintsimbi ezingenayo i-ferrous. Iidrill ze-M2 center ziyindlela eqhelekileyo yokukhetha iindawo zoomatshini ngokubanzi.
I-M35 HSS-Co — Udidi lweCobalt lwezicelo ezifuna uncedo
I-M35 (HS6-5-2-5, ekwaziwa ngokuba yi-HSSCo5) yongeza i-5% ye-cobalt kwisiseko se-M2. Oku kunyusa ukumelana nobushushu ukuya kuthi ga kwi-630–650°C kwaye kwandisa ubunzima ukuya kwi-63–66 HRC. I-M35 lolona hlobo lukhethwayo xa kufakwa intsimbi engagqwaliyo, intsimbi ye-alloy, okanye ezinye izinto ezinzima ukwenziwa ngomatshini, okanye kwimveliso ephezulu apho ubomi bezixhobo bubaluleke kakhulu.
Iinketho Zokugqiba Umphezulu
Indlela Yokukhetha: Isikhokelo Sezigqibo Esisebenzayo
Ukuba ubeka i-workpiece embindini eza kujika ngoko nangoko kwisetingi efanayo, uhlobo A lolona khetho lufanelekileyo. Lulula, lufutshane kancinci, kwaye lugubungela uninzi lwezicelo ezisemgangathweni ze-lathe centering.
Ukuba inkqubo yakho ibandakanya nayiphi na kwezi zilandelayo, chaza Uhlobo B:
• Isiqwenga somsebenzi sihamba phakathi koomatshini okanye sitshintsha phakathi kokusebenza
• Iinxalenye zigcinwa okanye ziphathwe emva kokuzibeka embindini nangaphambi kokujika kokugqibela
• Ukunyamezela kwakho kufuna ijiyometri yomngxuma osembindini ehambelanayo, ephindaphindwayo kuyo yonke imveliso
• Usebenza ngee-shafts ezichanekileyo apho amanzi avela kumngxuma osembindini owonakeleyo angamkelekanga
Xa ungaqinisekanga, uhlobo B yeyona nkcazelo ikhuselekileyo. I-chamfer yokhuseleko eyongezelelweyo ayongezi bunzima kumsebenzi wokubhola ngokwawo — iqinisekisa nje ukuba umphezulu wesihlalo uhlala ungaphazanyiswa.
