Zaɓin Adadin Reaming
⑴ Reaming allowance Reaming allowing shine zurfin yanke da aka tanada don reaming. Yawanci, alawus ɗin reaming ya fi ƙanƙanta fiye da alawus ɗin reaming ko gundura. Izinin reaming da yawa zai ƙara matsa lamba kuma yana lalata reamer, yana haifar da rashin ƙarfi na saman da aka sarrafa. Lokacin da gefe ya yi girma sosai, za a iya raba madaidaicin maɗaukaki da ƙaƙƙarfan hinge don tabbatar da buƙatun fasaha.
A daya bangaren kuma, idan alawus din billet din ya yi kadan, reamer din zai kare da wuri kuma ba za a iya yanke shi yadda ya kamata ba, kuma rashin karfin saman shima ba zai yi kyau ba. Gabaɗaya, izinin reaming shine 0.1 ~ 0.25mm, kuma don manyan ramukan diamita, izinin ba zai iya zama sama da 0.3mm ba.
Akwai ƙwarewar da ke ba da shawarar adana kauri na 1 ~ 3% na diamita na reamer azaman izinin reaming (ƙimar diamita). Misali, ya fi dacewa don ƙara Φ20 reamer tare da diamita na kusan Φ19.6: 20- (20*2/100) = 19.6 Ana ba da izinin reaming yawanci don kayan wuya da wasu kayan sararin samaniya.
(2) Yawan ciyarwa na reaming Adadin ciyarwar ya fi na hakowa girma, yawanci sau 2 ~ 3 nasa. Dalilin mafi girman ƙimar ciyarwa shine sanya reamer ya yanke kayan a maimakon kayan da aka lalata. Koyaya, ƙarancin darajar Ra na reaming yana ƙaruwa tare da haɓaka ƙimar abinci. Idan adadin ciyarwar ya yi ƙanƙanta, juzu'in radial zai ƙaru, kuma reamer ɗin zai ƙare da sauri, yana haifar da rawar jiki da girgiza saman ramin.

Standard karfe reamer sarrafa karfe sassa, don samun surface roughness Ra0.63, da ciyar kudi kada ya wuce 0.5mm/r, domin jefa baƙin ƙarfe sassa, shi za a iya ƙara zuwa 0.85mm/r.
⑶ Gudun tsintsiya madaurinki ɗaya da adadin yawan reaming Duk abubuwa suna da tasiri akan tarkacen saman ramin ramin, wanda daga cikinsu saurin reaming yana da babban tasiri. Idan ana amfani da reamer na karfe don reaming, mafi kyawun rashin ƙarfi Ra0.63; m , Don matsakaicin matsakaici na carbon karfe workpieces, reaming gudun kada ya wuce 5m / min, saboda gina-up gefen ba sauki faruwa a wannan lokaci, da kuma gudun ba high; a lokacin da ake reaming simintin ƙarfe, saboda guntu sun kakkarye zuwa granular, ba za a tara gefen gefen. Gefuna, don haka gudun za a iya ƙara zuwa 8 ~ 10m / min. Gabaɗaya, ana iya zaɓar saurin igiya na reaming azaman 2/3 na saurin hakowa akan abu ɗaya.
Misali, idan saurin igiya na hakowa shine 500r/min, yana da kyau a saita saurin sandal din reaming a 2/3 nasa: 500*0.660=330r/min
Abin da ake kira reamer yana da ban sha'awa. Kyakkyawar ban sha'awa yawanci yana da gefe ɗaya na 0.03-0.1 da saurin 300-1000. Yawan ciyarwar yana tsakanin 30-100, dangane da ko ana kiransa wuka.
