Daimondi ya 55-degree pa DCMT-21.51 carbide insert ili ndi mpumulo wa 7-degree. Bowo lapakati limakhala ndi sinki imodzi pakati pa 40 ndi 60 madigiri ndi chip breaker yomwe ili mbali imodzi yokha. Ili ndi makulidwe a mainchesi 0.094 (3/32 mainchesi), bwalo lolembedwa (I.C.) la 0.25″ (1/4″), ndi ngodya (mphuno) yotalika mainchesi 0.0156 (1/64″). DCMT21.51 (ANSI) kapena DCMT070204 ndi dzina lomwe laperekedwa kuyika (ISO). Onani tsamba la "Kugwirizana" pa LittleMachineShop.com kuti mupeze mndandanda wazinthu zomwe zimagwirizana ndi kampaniyo. Zowonjezera zitha kugulidwa limodzi. Chifukwa chake palibe chofunikira kuti mugule mitolo khumi yowerengera.

Zoyika za DCMT ndi zowonjezera zomwe zitha kulumikizidwa ku ma DCMT. Zoyika izi nthawi zambiri zimakhala m'mphepete mwa chidacho. Zofunsira zoyikapo zikuphatikiza izi:

Mawonekedwe

Pali mitundu ingapo yamitundu yotheka yoyika DCMT. Zoyikapo zozungulira kapena zozungulira zimagwiritsidwa ntchito ngati mphero ndi ma radius groove, motsatana. Mitundu ina imatha kusinthidwa kuti madera osagwiritsidwa ntchito m'mphepete azitha kugwiritsidwa ntchito mbali ina ya m'mphepete ikatha.

Makona atatu ndi ma trigon onse ndi zitsanzo za mawonekedwe a mbali zitatu. Zoyika mu mawonekedwe a makona atatu zimakhala ndi mawonekedwe a katatu, ndi mbali zitatu zofanana mu utali ndi mfundo zitatu zomwe zimakhala ndi makona a madigiri makumi asanu ndi limodzi iliyonse. Choyikapo cha makona atatu chomwe chimawoneka ngati makona atatu koma chokhala ndi mawonekedwe a katatu. Zitha kutenga mawonekedwe a mbali zopindika kapena zopindika zapakati pambali, zomwe zimapangitsa kuti ma angles ophatikizidwawo athe kupezedwa pa malo oyikapo.

Zithunzi za DCMT

Ma diamondi, mabwalo, makona, ndi rhombic ndi zitsanzo za mawonekedwe okhala ndi mbali zinayi zotchedwa insert. Kuchotsa zakuthupi, ndikuyika kukhala ndi mbali zinayi, ndi ngodya ziwiri zakuthwa zimadziwika kuti cholowetsa diamondi. Nsonga za square cutting zimakhala ndi mbali zinayi zofanana. Zoyikapo zamakona zimakhala ndi mbali zinayi, ndipo ziwiri zimakhala zazitali kuposa mbali ziwiri zina. Grooving ndi ntchito yofala pazoyika izi; kwenikweni kudula m'mphepete ili pamphepete lalifupi la kuikapo. Zolowetsa zomwe zimadziwika kuti rhombic kapena parallelograms zili ndi mbali zinayi ndipo zimapindika mbali zonse zinayi kuti zipereke chilolezo chodulira.

Zolowetsa zimatha kupangidwanso ngati pentagon, yomwe ili ndi mbali zisanu zofanana m'litali, ndi zolowetsa octagonal, zomwe zimakhala ndi mbali zisanu ndi zitatu.

Mitundu yosiyanasiyana ya zoyikapo imatha kusiyanitsa wina ndi mnzake kutengera nsonga za zoyikapo, kuphatikiza pa geometry ya zoyikazo zokha. Choyikapo chokhala ndi "mphuno ya mpira" ya hemispheric yomwe utali wake ndi theka la m'mimba mwake wodula umadziwika kuti mphero ya mphuno. Mtundu wa mphero uwu ndi wabwino kwambiri podula ma semicircles achikazi, grooves, kapena radii. Nthawi zambiri amagwiritsidwa ntchito podulira mphero, mphero ya nsonga ya radius ndi choyikapo chowongoka chokhala ndi nsonga ya mphero m'mbali mwake. Zomwe zimagwirizanitsidwa ndi zodulira mphero, mphero zachamfer zimayenera kuyika mbali kapena malekezero omwe ali ndi malo opindika kunsonga. Gawoli limalola mphero kuti ipange chogwirira ntchito chokhala ndi ma angled odulidwa kapena m'mphepete mwa chamfered. Choyikapo chomwe chimadziwika kuti fupa la galu chimakhala ndi mbali ziwiri zodulira, choyambira chopyapyala, ndipo, monga momwe dzinalo likusonyezera, mbali zonse ziwiri zodulira. Kuyika kwamtunduwu nthawi zambiri kumagwiritsidwa ntchito popanga grooving. Mbali ya nsonga yophatikizidwa imatha kuyambira 35 mpaka 55 madigiri, komanso 75, 80, 85, 90, 108, 120, ndi 135 madigiri.

Zofotokozera

Mwambiri, mukukula kwa sert kumagawidwa molingana ndi bwalo lolembedwa (I.C.), lomwe limadziwikanso kuti bwalo bwalo lomwe limakwanira mkati mwa geometry yoyika. Izi zimagwiritsidwa ntchito poyika zolozera zambiri, kupatula zoyikapo zamakona anayi ndi zina za parallelogram, zomwe zimagwiritsa ntchito kutalika ndi m'lifupi m'malo mwake. Zofunikira zoyikapo za DCMT ndi makulidwe, utali wozungulira (ngati kuli kotheka), ndi ngodya ya chamfer (ngati ikuyenera). Mawu oti "unground," "indexable," "chip breaker," ndi "dished" amagwiritsidwa ntchito mobwerezabwereza kufotokoza mawonekedwe a zoyika za DCMT. Zophatikizidwira zoyikapo zimatha kupindika kapena kukhala opanda bowo.

Zipangizo

Carbide, micro-grain carbides, CBN, ceramic, cermet, cobalt, diamondi PCD, chitsulo chothamanga kwambiri, ndi silicon nitride ndizo zida zomwe zimagwiritsidwa ntchito kwambiri pomanga zoyika za DCMT. Kukana kuvala ndi kuyika moyo kungathe kuonjezedwa pogwiritsa ntchito zokutira. Zopaka pazoyika za DCMT zimaphatikizapo titanium nitride, titanium carbonitride, titanium aluminium nitride, aluminium titanium nitride, aluminium oxide, chromium nitride, zirconium nitride, ndi diamondi DLC.
