Muhimman Matsayin Haɓakawa Gefuna akan Madaidaicin Platform Granite

A cikin duniyar metrology da madaidaicin taro, babban abin da aka fi mayar da hankali shine, daidai, akan shimfidar shimfidar dandali na granite. Koyaya, ƙera babban inganci, mai dorewa, da amintaccen farantin ƙasa yana buƙatar kulawa ga gefuna-musamman, al'adar ɗab'a ko zagaye su.

Duk da yake ba ya yin tasiri kai tsaye ga daidaiton ƙananan micron na jirgin sama mai aiki, ƙwanƙolin chamfered wani abu ne mai mahimmanci wanda ke haɓaka tsawon lokacin farantin, yana ba da kariya ga kayan aunawa mai mahimmanci, kuma yana tabbatar da amincin ma'aikacin. Abu ne mai mahimmanci na zamani, ƙwararrun masana'antar granite.

Wajibcin Karya Baki

Me yasa masana'antun da gangan suke cire kaifi, kusurwar 90∘ inda saman aiki ya hadu da gefen gefen granite slab? Yana tafasa ƙasa zuwa manyan dalilai guda uku: karko, aminci, da aiki.

1. Hana Chipping da Lalacewa

Granite yana da wuyar gaske, amma wannan taurin kuma yana sa kaifi, gefen da ba a goyan bayansa ba kuma yana da saukin kamuwa da guntuwa. A cikin masana'anta ko dakin gwaje-gwaje na daidaitawa, motsi yana dawwama. Idan ma'auni mai nauyi, na'ura, ko kayan aiki da gangan ya yi karo da kusurwa mai kaifi, wanda ba a kula da shi ba, tasirin na iya haifar da guntu cikin sauƙi ya karye.

• Kare Zuba Jari: Ƙaƙƙarfan ƙaƙƙarfan (ko mai zagaye/radiused) gefen yana haifar da yanki mai ƙarfi, mai gangare. Wannan “karshen gefen” yadda ya kamata yana rarraba tasirin haɗari a kan wani yanki mai girma, yana rage yawan damuwa da haɗarin guntuwa. Kare gefen yana nufin kare mutuncin tsarin da ƙimar kyawun farantin duka.
• Hana Burrs: Ba kamar ƙarfe ba, granite ba ya haɓaka burrs, amma guntu ko nick na iya ƙirƙirar ƙasa mara daidaituwa wanda zai iya ƙwace tufafin tsaftacewa ko haifar da haɗari. Gefen zagaye yana rage girman waɗannan layukan kuskure.

2. Inganta Tsaron Ma'aikata

Ƙaƙƙarfan nauyi da kaifi, gefuna na dabi'a na babban dutsen dutsen dutse yana haifar da haɗari mai tsanani. Karɓawa, jigilar kaya, har ma da yin aiki kusa da farantin da ba a ɗaure ba yana da haɗari.

• Rigakafin Rauni: Ƙaƙƙarfan ƙaƙƙarfan ƙaƙƙarfan ƙaƙƙarfan dutsen dutsen yana iya yanke ko tarke mai fasaha cikin sauƙi. Watsewar gefen shine farkon ma'aunin aminci, cire yuwuwar rauni yayin saiti, daidaitawa, da amfanin yau da kullun.

3. Inganta Tsawon Aiki

Chamfering taimako a cikin gaba ɗaya amfani da kiyaye farantin. Yana sauƙaƙe motsi mai laushi na sutura da kayan haɗi kuma yana sauƙaƙe aikace-aikacen suturar kariya ko tef ɗin gefen. Tsaftace, gama gari alama ce ta kayan aikin awo na ƙwararru.

Zaɓin Ƙididdigar Dama: R-Radius vs. Chamfer

Lokacin ƙayyadaddun magani na gefen, masana'antun yawanci suna amfani da ƙirar radius, kamar R2 ko R3 (inda 'R' ke tsaye don Radius, lambar kuma ita ce ma'auni a cikin millimeters). Chamfer, ko “bevel,” a fasahance lebur ne, yanke kusurwa, amma galibi ana amfani da sharuddan musaya don nuni ga kowane gefen da ya karye. A madaidaicin granite, radius mai zagaye yawanci ana fifita don mafi girman juriyar guntu.

Fahimtar R2 da R3

Zaɓin ƙayyadaddun bayanai, kamar radius R2 ko R3, shine farkon batun sikeli, ƙayatarwa, da kulawa.

• R2 (Radius 2 mm): Wannan na kowa, dabara, da radius mai aiki, galibi ana amfani da shi akan ƙananan faranti na dubawa sosai. Yana ba da isasshen aminci da kariyar guntu ba tare da kasancewa rinjaye na gani ba.
• R3 (Radius 3 mm): Radius mafi girma kaɗan, R3 yana ba da ingantaccen kariya daga tasiri mai nauyi. Ana ƙididdige shi akai-akai don manyan tebura, kamar waɗanda aka yi amfani da su a ƙarƙashin Injin Aunawa Daidaitawa (CMMs) ko wasu kayan aiki masu nauyi, inda haɗarin tasirin gefen haɗari ya fi girma.

Radius baya bin ƙaƙƙarfan ƙa'idodin masana'antu (kamar maki ASME flatness) amma masana'anta sun zaɓa don ya yi daidai da girman farantin gabaɗaya da yanayin aiki da aka yi niyya. Don babban madaidaicin granite, tabbatar da daidaito, ingantaccen gefen R3 shine saka hannun jari a dorewa na dogon lokaci da amincin bene na kanti.

Daga ƙarshe, ƙaramin daki-daki na gefen R-radius alama ce mai ƙarfi na ƙudurin masana'anta ga ingancin da ya wuce saman shimfidar aiki, yana tabbatar da cewa duk dandamalin yana da ɗorewa, mai aminci, kuma an gina shi don dorewa.
