Idayimani ye-55-degree kwi-DCMT-21.51 ifake i-carbide ine-7-degree relief. Umngxuma osembindini une-countersink enye phakathi kwe-40 kunye ne-60 degrees kunye ne-chip breaker esecaleni elinye. Ibonisa ubukhulu bee-intshi ze-0.094 (i-intshi ezi-3/32), isangqa esibhaliweyo (I.C.) ye-0.25" (1/4″), kunye nekona (impumlo) irediyasi enomlinganiselo we-0.0156 intshi (1/64″). I-DCMT21.51 (ANSI) okanye i-DCMT070204 luphawu olunikwe ukufakela (ISO). Khangela "Ukuhambelana" iphepha kwi-LittleMachineShop.com ukufumana uluhlu lwezinto ezihambelana nenkampani. Ukufakwa kunokuthengwa kanye. Ngaloo ndlela akukho mfuneko yokuthenga i-ten-count bundle of inserts.

Ufakelo lwe-DCMT zizincedisi ezinokudityaniswa ne-DCMTs. Ezi zifakelo zihlala zigcina eyona nxalenye yokusika yesixhobo. Izicelo zofakelo ziquka oku kulandelayo:

iyadika

ukwakhiwa

ukwahlukana kunye nokunqunyulwa

ukugrumba

grooving

ukuzonwabisa

ukugaya

imigodi

isarha

ukucheba nokunqunqa, ngokulandelelanayo

Iimbonakalo

Kukho iintlobo ngeentlobo zeejiyometri ezinokwenzeka zofakelo lwe-DCMT. Ufakelo olungqukuva okanye olusetyhula lusetyenziswa kwiinkqubo ezifana neqhosha lokusila kunye ne-radius groove turning, ngokulandelelanayo. Ezinye iindidi zinokulungiswa ukuze iindawo ezingasetyenziswanga zomphetho zisetyenziswe xa inxenye yomphetho igugile.

Unxantathu kunye nonxantathu yimizekelo yomibini yeefom zokufaka ezimacala mathathu. Izinto ezifakwe kwimilo yoonxantathu zinemilo engunxantathu, ezinamacala amathathu alinganayo ngobude kunye namanqaku amathathu aquka ii-engile ezingamashumi amathandathu edigri lilinye. I-trigon insert sisifakelo esineekona ezintathu esifana nonxantathu kodwa sinemilo engunxantathu eguquliweyo. Ingathatha ifom yecala eligobileyo okanye i-angles ephakathi kumacala, okwenza ukuba ii-angles ezinkulu ezibandakanyiweyo zifezekiswe kwiindawo zokufaka.

DCMT Faka

Iidayimani, izikwere, iixande, kunye nerhombiki yimizekelo yeefom ezinamacala amane abizwa ngokuba zii-insert. Ukususa izinto, kunye nokufaka ukuba namacala amane, kunye nee-engile ezimbini ezibukhali zaziwa njenge-diamond insert. Iingcebiso zokusika isikwele zibonisa amacala amane alinganayo. Ukufakwa koxande kunamacala amane, amabini made kunamanye amacala amabini. I-Grooving sisicelo esiqhelekileyo kwezi zifakelo; umgca wokusika wangempela ubekwe kwiindawo ezimfutshane zokufaka. Ukufakwa okubizwa ngokuba yi-rhombic okanye i-parallelograms inamacala amane kwaye i-angled kuwo onke amacala amane ukubonelela ngokucocwa kwendawo yokusika.

Ukufakwa kunokwenziwa ngokwemilo yepentagon, enamacala amahlanu alinganayo ngobude, kunye nokufakwa kwe-octagonal, enamacala asibhozo.

Iindidi ezahlukahlukeneyo zokufaka ziyakwazi ukwahlula omnye komnye ngokusekelwe kwii-angles ze-tip of the inserts, ngaphezu kwejometri yokufakwa ngokwabo. I-insert ene-hemispheric "ball nose" ene-radius enye yesiqingatha sobubanzi be-cutter eyaziwa ngokuba yi-ball nose mill. Olu hlobo lokusila lugqwesile ekusikeni iisemicircle zabasetyhini, iigrooves, okanye iradii. Ngokuqhelekileyo isetyenziswe kwi-milling cutters, i-radius tip tip yifake echanekileyo kunye ne-radius yokusila kwiingcebiso zemida yokusika. Ngokuqhelekileyo idityaniswe kwimilling cutter holders, i-chamfer tip tip mills kufuneka ifake amacala okanye iziphelo ezinommandla one-angle kwincam. Eli candelo livumela i-mill ukuba yenze i-workpiece ene-angled cut okanye i-edge chamfered. I-insert eyaziwa ngokuba yi-dogbone inekona ezimbini zokusika, isiseko esincinci esinyukayo, kwaye, njengoko igama libonisa, iimpawu zokusika ezibanzi kuzo zombini iziphelo. Olu hlobo lofakelo luqhele ukusetyenziselwa ukukrola. I-angle ye-tip efakiweyo inokuvela kwi-35 ukuya kwi-55 degrees, kunye ne-75, 80, 85, 90, 108, 120, kunye ne-135 degrees.

Iinkcukacha

Ngokubanzi, kwiubungakanani be-sert buhlelwa ngokwesangqa esibhaliweyo (I.C.), eyaziwa ngokuba yi-diameter yesangqa esingena ngaphakathi kwejometri yofakelo. Oku kusetyenziswa kuninzi lofakelo olunophawu, ngaphandle koxande kunye nofakelo lweparalelogram, olusebenzisa ubude nobubanzi endaweni yoko. Iimfuno ezibalulekileyo zokufaka i-DCMT bubukhulu, iradiyasi (ukuba ikhona), kunye ne-angle ye-chamfer (ukuba ikhona). Amagama "unground," "indexable," "chip breaker," kunye "dished" asetyenziswa rhoqo ukuchaza iimpawu DCMT ufakelo. Iziqhoboshelo zofakelo zinokujijwa okanye zingabinamngxuma.

Izinto eziphathekayo

I-Carbide, i-micro-grain carbides, i-CBN, i-ceramic, i-cermet, i-cobalt, i-diamond PCD, i-high-speed steel, kunye ne-silicon nitride zezona zinto zixhaphakileyo ezisetyenziswa ekwakhiweni kokufakwa kwe-DCMT. Ukugqoka ukuchasana kunye nokufaka ubomi kunokunyuswa zombini kunye nokusetyenziswa kweengubo. Iingubo zokufakelwa kwe-DCMT ziquka i-titanium nitride, i-titanium carbonitride, i-titanium aluminium nitride, i-aluminium titanium nitride, i-aluminium oxide, i-chromium nitride, i-zirconium nitride, kunye ne-diamond DLC.
