3. B\u00f6lme kafas\u0131<\/p>

NC indeksleme kafas\u0131, NC freze makinesinin ve i\u015fleme merkezinin ortak bir aksesuar\u0131d\u0131r. \u0130\u015flevi, NC tak\u0131m tezgah\u0131n\u0131n belirtilen i\u015fleme s\u00fcrecini tamamlamas\u0131n\u0131 sa\u011flamak i\u00e7in kontrol cihaz\u0131n\u0131n sinyaline veya talimat\u0131na g\u00f6re d\u00f6ner indeksleme veya s\u00fcrekli d\u00f6ner besleme hareketi yapmakt\u0131r.

Aynalar\u0131 se\u00e7mek i\u00e7in en alakal\u0131 fakt\u00f6rler nelerdir?<\/strong><\/h2>

\"\"<\/figure>

1. Mil y\u00fck kapasitesi<\/p>

The maximum allowable weight of the lathe spindle is based on the bearing load capacity. If the weight of the chuck and workpiece combination is too large, the bearing may be overloaded. For those machining tasks with danger beyond the limit, this danger may determine people’s choice of workpiece fixture. The weight of jaw chuck is often larger than that of the same spring chuck. Therefore, the spring chuck is the appropriate choice when the weight needs to be controlled.<\/p>

2. Mil h\u0131z\u0131<\/p>

Yayl\u0131 pens, iki ana nedenden dolay\u0131 \u00e7ok y\u00fcksek i\u015f mili h\u0131zlar\u0131nda tornalama i\u00e7in genellikle daha iyi bir se\u00e7imdir:<\/p>

Bunun bir nedeni aynan\u0131n kalitesiyle ilgilidir. \u00c7eneli aynan\u0131n ve yayl\u0131 bilezi\u011fin ayn\u0131 i\u015f mili g\u00fcc\u00fcyle \u00e7al\u0131\u015ft\u0131r\u0131ld\u0131\u011f\u0131 varsay\u0131ld\u0131\u011f\u0131nda, daha a\u011f\u0131r \u00e7eneli aynan\u0131n gereken h\u0131za ula\u015fmas\u0131 daha uzun s\u00fcrer. Uzun bir h\u0131zlanma s\u00fcresi, \u00e7al\u0131\u015fma d\u00f6ng\u00fcs\u00fcn\u00fc uzatacak ve \u00fcretkenli\u011fi azaltacakt\u0131r.<\/p>

Di\u011fer bir neden de merkezka\u00e7 kuvveti ile ilgilidir, \u00e7\u00fcnk\u00fc RPM'nin kare de\u011feri ile artar, bu nedenle y\u00fcksek h\u0131zl\u0131 kesme durumunda bu de\u011fer \u00e7ok \u00f6nemlidir. \u00d6rne\u011fin, i\u015f mili h\u0131z\u0131n\u0131 iki kat\u0131na \u00e7\u0131kar\u0131rsan\u0131z, merkezka\u00e7 kuvveti orijinalin d\u00f6rt kat\u0131 olacakt\u0131r. Bu kuvvet, ayna \u00e7enelerini merkezden uza\u011fa do\u011fru \u00e7eker ve \u00e7o\u011fu zaman kenetleme kuvvetini azalt\u0131r. Bununla birlikte, yayl\u0131 pens ile merkezka\u00e7 kuvveti belirgin bir etkiye neden olmaz. Bu nedenle, s\u0131k\u0131\u015ft\u0131rma kuvveti t\u00fcm i\u015flem h\u0131z\u0131 aral\u0131\u011f\u0131nda daha kararl\u0131 olacakt\u0131r.<\/p>

3. \u0130\u015fleme i\u015flemi<\/p>

Yayl\u0131 halka, yaln\u0131zca se\u00e7ilen temas alan\u0131nda de\u011fil, par\u00e7an\u0131n t\u00fcm \u00e7evresine s\u0131k\u0131\u015ft\u0131rma kuvveti uygular. Bu nedenle, ikincil i\u015fleme projeleri i\u00e7in \u00f6zellikle \u00f6nemli olan iyi bir e\u015f merkezlilik elde edilebilir. \u0130kincil i\u015fleme, birincil i\u015fleme ile ilgili do\u011frulu\u011fu dikkate almal\u0131d\u0131r, \u00e7\u00fcnk\u00fc \u00e7eneli ayna birincil i\u015fleme i\u00e7in kullan\u0131ld\u0131\u011f\u0131nda bile yayl\u0131 pensin do\u011fru s\u0131kma kabiliyeti g\u00fc\u00e7l\u00fcd\u00fcr, Yayl\u0131 pens ikincil i\u015fleme i\u00e7in de kullan\u0131labilir. \u0130\u00e7i bo\u015f yumu\u015fak \u00e7eneli ayna, 0,0006 ila 0,0012 in\u00e7 aral\u0131\u011f\u0131nda TIR (toplam okuma) tekrarlama do\u011frulu\u011fu elde edebilirken, yayl\u0131 pensin tipik tekrarlama do\u011frulu\u011fu 0,0005 in\u00e7 TIR veya daha iyidir. \u0130kincil i\u015fleme hassasiyetini daha da iyile\u015ftirmek i\u00e7in yayl\u0131 halkan\u0131n e\u015fmerkezlili\u011fi kurulum s\u0131ras\u0131nda da ayarlanabilir.<\/p>

4. \u0130\u015f par\u00e7as\u0131 boyutu<\/p>

Yayl\u0131 pensler, \u00e7ap\u0131 3 in\u00e7ten k\u00fc\u00e7\u00fck i\u015f par\u00e7alar\u0131 i\u00e7in idealdir. Yayl\u0131 pens, i\u015f par\u00e7as\u0131n\u0131n uzunlu\u011funu s\u0131n\u0131rlar. \u00d6zellikle yayl\u0131 pens, uzunlu\u011fu \u00e7eneli aynadan daha uzun oldu\u011fu i\u00e7in tak\u0131m tezgah\u0131n\u0131n eksenel (Z ekseni) hareket aral\u0131\u011f\u0131n\u0131 s\u0131n\u0131rlar. \u0130\u015f par\u00e7as\u0131n\u0131n i\u015fleme uzunlu\u011fu, tak\u0131m tezgah\u0131n\u0131n neredeyse t\u00fcm mevcut strokuna ihtiya\u00e7 duydu\u011funda, \u00e7eneli ayna muhtemelen kullan\u0131l\u0131r.<\/p>

5. Parti boyutunun i\u015flenmesi<\/p>

Yayl\u0131 pensler, b\u00fcy\u00fck ve k\u00fc\u00e7\u00fck toplu i\u015fleme g\u00f6revleri i\u00e7in uygundur.<\/p>

K\u00fc\u00e7\u00fck parti ve \u00e7oklu g\u00f6revlerin i\u015fleme durumlar\u0131nda, yayl\u0131 aynan\u0131n avantajlar\u0131 \u00fcr\u00fcn d\u00f6n\u00fc\u015ft\u00fcrme s\u00fcresi ile ilgilidir. Standart \u00e7eneli aynan\u0131n \u00e7ene de\u011fi\u015fimi yakla\u015f\u0131k 15 ila 20 dakika s\u00fcrer, h\u0131zl\u0131 de\u011fi\u015ftirme i\u00e7in \u00f6zel olarak kullan\u0131lan \u00e7eneli ayna 1 dakika, h\u0131zl\u0131 de\u011fi\u015ftirme yayl\u0131 aynan\u0131n ayna de\u011fi\u015fimi ise sadece 15 ila 20 saniye s\u00fcrer. \u00dcr\u00fcn s\u0131k s\u0131k de\u011fi\u015fti\u011finde, zamandan \u00f6nemli \u00f6l\u00e7\u00fcde tasarruf edilir.<\/p>

\u0130\u015fleme partisi b\u00fcy\u00fck oldu\u011funda, kaydedilen kenetleme s\u00fcresi de toplanabilir. Yayl\u0131 aynan\u0131n a\u00e7\u0131lma ve kapanma s\u00fcresi, \u00e7eneli aynan\u0131nkinden daha k\u0131sad\u0131r. \u0130\u015fleme d\u00f6ng\u00fcs\u00fc s\u00fcresi, bir i\u015f par\u00e7as\u0131ndan sonraki i\u015f par\u00e7as\u0131na kadar kesilmeyen s\u00fcreyi azaltarak azalt\u0131labilir.<\/p>

6. \u0130\u015f par\u00e7as\u0131 boyut aral\u0131\u011f\u0131<\/p>

Bu nedenle yayl\u0131 pensler se\u00e7im i\u00e7in uygundur. Ancak, tutarl\u0131 \u00e7ap \u00f6l\u00e7\u00fcmlerinin olmamas\u0131, mutlaka yayl\u0131 penslerin kullan\u0131lmas\u0131na engel te\u015fkil etmez.

Therefore, NC High-speed machining process can be generally divided into: rough machining – semi finishing – corner cleaning – finishing and so on. For parts with high precision requirements, it is sometimes necessary to carry out secondary and semi finishing, and then finish machining. After rough machining, the parts can be cooled naturally to eliminate the internal stress caused by rough machining and reduce deformation. The allowance left after rough machining shall be greater than the deformation, generally 1 ~ 2mm. During finish machining, the finished surface of parts shall maintain a uniform machining allowance, generally 0.2 ~ 0.5mm, so that the tool is in a stable state in the machining process, which can greatly reduce the cutting deformation, obtain good surface machining quality and ensure the accuracy of products.<\/p>
