Yadda za a zabi carbide saw ruwa?

Siminti carbide saw ruwa ya ƙunshi sigogi da yawa kamar nau'in alloy cutter head, kayan tushe, diamita, adadin hakora, kauri, siffar haƙori, kusurwa, diamita na rami, da sauransu. Waɗannan sigogi sun ƙayyade. da sarrafa ikon da yankan yi na saw ruwa. Lokacin zabar igiyar gani, ya zama dole a zaɓi daidai gwargwado bisa ga nau'in, kauri, saurin sawing, jagorar sawing, saurin ciyarwa da faɗin sawing na kayan aikin.

(1) Zaɓin nau'ikan siminti na siminti

Abubuwan da aka saba amfani da su na simintin carbide sune tungsten-cobalt (lambar YG) da tungsten-titanium (lambar YT). Saboda kyakkyawan tasirin juriya na tungsten da cobalt carbides, an fi amfani da su a cikin masana'antar sarrafa itace. Samfuran da aka saba amfani da su wajen sarrafa itace sune YG8-YG15. Lamba bayan YG yana nuna yawan adadin cobalt. Tare da haɓakar abun ciki na cobalt, tasirin tasiri da ƙarfin juzu'i na gami yana inganta, amma taurin da juriya sun ragu. Zaɓi bisa ga ainihin halin da ake ciki.

(2) Zaɓin substrate

1.65Mn spring karfe yana da kyau elasticity da plasticity, tattali abu, mai kyau zafi magani taurare-ikon, low dumama zafin jiki, sauki nakasawa, kuma za a iya amfani da saw ruwan wukake tare da kananan yankan bukatun.

2. Carbon kayan aiki karfe yana da babban carbon abun ciki da kuma high thermal watsin, amma ta taurin da lalacewa juriya sauke sharply a 200℃-250 ℃ zafin jiki, da zafi magani nakasawa ne babba, da hardenability ne matalauta, da tempering lokaci ne mai tsawo da kuma sauki crack. Kera kayan tattalin arziki don yankan kayan aikin kamar T8A, T10A, T12A, da sauransu.

3. Idan aka kwatanta da carbon kayan aiki karfe, gami kayan aiki karfe yana da kyau zafi juriya, sa juriya, da kuma kyau handling yi.

4. Ƙarfe na kayan aiki mai sauri yana da kyau mai ƙarfi, ƙarfin ƙarfi da ƙarfi, da ƙarancin ƙarancin zafi. Karfe ne mai ƙarfi mai ƙarfi, kuma kwanciyar hankalin sa na thermoplastic ya dace da kera manyan ƙwanƙolin ƙwanƙwasa-baƙi.

(3) Zaɓin diamita

A diamita na saw ruwa yana da alaka da sawing kayan aiki da kuma kauri daga cikin sawing workpiece. Matsakaicin diamita na katako yana da ƙananan, kuma saurin yankan yana da ƙananan ƙananan; mafi girman diamita na katako na katako, mafi girma da buƙatun buƙatun katako da kayan aikin katako, kuma mafi girman ingancin sawing. Ana zaɓin diamita na waje na ganga bisa ga nau'ikan ma'aunin madauwari daban-daban kuma ana amfani da tsintsiya mai tsayi iri ɗaya.

Matsakaicin daidaitattun sassa sune: 110MM (inci 4), 150MM (inci 6), 180MM (inci 7), 200MM (inci 8), 230MM (inci 9), 250MM (inci 10), 300MM (inci 12), 350MM. ( inci 14), 400MM (inci 16), 450MM (inci 18), 500MM (inci 20), da sauransu. Ƙarƙashin tsagi na ƙasa na madaidaicin ma'aunin gani an tsara su don zama 120MM.

(4) Zaɓin adadin hakora

Gabaɗaya magana, yawancin hakora suna da yawa, ana iya yanke gefuna da yawa a cikin lokaci ɗaya, kuma mafi kyawun aikin yankan shine. Duk da haka, yawan adadin yankan hakora, ana buƙatar ƙarin siminti na siminti, kuma farashin simintin yana da yawa, amma haƙoran suna da yawa. , Adadin kwakwalwan kwamfuta tsakanin hakora ya zama karami, wanda yake da sauƙi don sa igiyar gani don zafi; Bugu da kari, akwai da yawa gani hakora, kuma idan adadin abinci ba daidai ba daidai ba, yankan adadin kowane hakori kadan ne sosai, wanda zai kara tsananta gogayya tsakanin yankan gefe da workpiece da kuma shafi rayuwar sabis na yanke. baki. . Yawanci tazarar haƙori shine 15-25mm, kuma ya kamata a zaɓi adadin hakora masu dacewa bisa ga kayan da za a yi.

(5) Zaɓin kauri

A kauri daga cikin saw ruwa A ka'idar, muna fatan cewa sirara da saw ruwa, mafi alhẽri, saw kabu a zahiri wani irin amfani. Abubuwan da ake amfani da su na alloy saw ruwa tushe da kuma tsarin masana'antu na katako na katako suna ƙayyade kauri na katako. Idan kauri yana da bakin ciki sosai, igiyar gani yana da sauƙin girgiza lokacin aiki, wanda ke shafar tasirin yanke. Lokacin zabar kauri na katako, ya kamata a yi la'akari da kwanciyar hankali na katako da kayan da za a yi. Kauri da ake buƙata don wasu kayan aiki na musamman shima takamaiman ne, kuma yakamata a yi amfani da shi bisa ga buƙatun kayan aiki, kamar ƙwanƙolin zato, tsintsiya madaurin ruwa, da sauransu.
