Kutheni i-drill bit yahlukile ngombala? Ingaba uyazi?

Ngaba kukho naluphi na unxulumano phakathi kombala we-drill kunye nomgangatho

Okokuqala: akunakwenzeka ukwahlula umgangatho we-drill bit kumbala. Akukho budlelwane buthe ngqo kwaye bungenakuphepheka phakathi kombala kunye nomgangatho. Amasuntswana okubhola ahlukeneyo ahluke kakhulu kwitekhnoloji yokucubungula. Ewe kunjalo, unokwenza isigwebo esirhabaxa kumbala, kodwa i-drill drill bits yangoku ekumgangatho ophantsi Iza kucubungula imibala yazo ukuze kuphunyezwe imbonakalo yomgangatho ophezulu wokuqhuba.

Uthini umahluko phakathi kwemibala eyahlukeneyo yokudweba

Umgangatho ophezulu ogcweleyo ogcweleyo we-speed-speed drill bits zihlala zibonakala zimhlophe. Kakade ke, amasuntswana e-rolled drill anokwenziwa mhlophe ngokusila okucolekileyo kwisangqa sangaphandle. Isizathu somgangatho ophezulu kukuba ukongeza kwizinto eziphathekayo ngokwazo, ulawulo lomgangatho ngexesha lenkqubo yokusila lukwangqongqo kakhulu, akukho kutshisa kwindawo yesixhobo. Umnyama yi-nitrided drill bit. Yindlela yeekhemikhali yokuphucula ukuqina kwesixhobo ngokubeka isixhobo esigqityiweyo kumxube we-ammonia kunye nomphunga wamanzi kunye nokubeka phantsi kweqondo lokushisa kwe-540-560C °.

Okwangoku, ininzi ye-black drills kwimarike emnyama kuphela (ukuze igubungele ukutshisa okanye ulusu olumnyama ebusweni besixhobo), kodwa umphumo wangempela wokusetyenziswa awuzange uphuculwe ngokufanelekileyo.

Kukho iinkqubo ezintathu zokuvelisa i-drill bits. Umnyama ugoqiwe, umbi kakhulu.Ezimhlophe zichetyiwe kwaye zikhazimlisiwe. Ngokungafaniyo nokuqengqeleka, okungavelisi i-oxidation yobushushu obuphezulu, ulwakhiwo lweenkozo zentsimbi ayonakaliswa, kwaye lusetyenziselwa ukugrumba ii-workpieces zobunzima obuphezulu. I-tan drill bit ibizwa ngokuba yi-cobalt-containing drill kwishishini. Lo ngumgaqo ofihlakeleyo wolu shishino lwe-drill.

Iidayimani ezineCobalt zazimhlophe ekuqaleni kwaye ziveliswa ngokusila. Xa zathi kamva zenziwa iathom, zenziwa zaba tyheli-mdaka (ngokuqhelekileyo ezibizwa ngokuba yiamber), eyona isasazwa kakuhle ngoku. I-M35 (Co 5%) nayo inombala wegolide. Olu hlobo lwe-drill lubizwa ngokuba yi-titanium-plated drill, eyahlulahlulwe ibe yi-decorative plating kunye ne-industrial plating. I-decorative plating ayinasiphumo konke konke, intle kwaye igolide. I-industrial plating ilungile kakhulu, ubunzima bunokufikelela kwi-HRC78, engaphezulu kuneedayimani ezine-cobalt (HRC54 °).

Ekubeni umbala awusiyo inqobo yokugweba umgangatho we-drill, uyithenga njani i-drill?

Ukujonga kumava, ngokubanzi, umhlophe ngokuqhelekileyo wenziwa nge-speed-speed steel drill bit, umgangatho kufuneka ube ngowona ungcono. Ezo zegolide zii-titanium nitride ezicandiweyo kwaye zidla ngokuba zezona zilungileyo okanye zikhohliswa kakubi. Umgangatho omnyama nawo awulingani. Ezinye zenziwe ngentsimbi ye-carbon engasebenziyo, ekulula ukuyikhupha kwaye kulula ukuyirusa, ngoko kufuneka ibe mnyama.

 

Ngokuqhelekileyo, xa uthenga i-drill, unokubona uphawu lokuthengisa kwi-drill shank kunye nophawu lokunyamezela. I-logo icacile, kwaye umgangatho we-laser okanye i-corrosion yombane ayibi kakhulu. Ukuba ngumlingiswa ogxininisiweyo, ukuba umda womlingiswa uyagqabhuka, umgangatho we-drill umpofu, kuba i-contour ye-bulged character iya kubangela ukuba ukuchaneka kwe-drill kube ngaphantsi kwemfuneko, kunye nomda womlingiswa. icacile, ilungile kakhulu kwaye i-cylindrical surface ye-drill shank Junctions isemgangathweni olungileyo. Ukongezelela, kuxhomekeke kumgca wokusika we-drill tip. Umphetho we-drill-grind drill ulungile kakhulu, umphezulu we-spiral uhlangabezana neemfuno, kwaye umgangatho ompofu umbi kumphezulu wekona yangasemva.
