Bayan zaɓin abin yanka, mutane da yawa ba sa bayyana akan saita saurin yankan, saurin juyawa da zurfin yankan.Wannan yana da haɗari sosai, zai haifar da raguwa mai yankewa, kayan narke ko ƙonewa.Akwai hanyar lissafi?Amsar ita ce eh!
1. The yankan gudun:
Gudun yankan yana nufin saurin saurin da aka zaɓa akan kayan aiki dangane da madaidaicin ma'auni akan workpiece.
Vc=πDN/1000
Gudun yankan Vc, Raka'a: m/min
N- saurin jujjuyawa, Raka'a: r/min
D- Cutter diamita, Raka'a: mm
Gudun yankan yana shafar abubuwa kamar kayan aiki, kayan aikin aiki, tsaurin kayan aikin injin, da yanke ruwa.Yawancin lokaci ana amfani da ƙananan saurin yankan don na'ura mai wuya ko ductile karafa, wanda ke da karfi yankan amma zai iya rage kayan aiki da kuma tsawaita rayuwar kayan aiki.Ana amfani da saurin yankan mafi girma sau da yawa don injin kayan laushi don samun kyakkyawan ƙarewar ƙasa.Hakanan za'a iya amfani da saurin yankan mafi girma a ƙaramin diamita abin yanka wanda ake amfani da shi don yin ƙananan yankan akan kayan aiki na kayan aiki ko daidaitattun abubuwan da aka gyara.Misali, niƙa gudun high-gudun karfe abun yanka ne 91 ~ 244m / min ga aluminum, da kuma 20 ~ 40m / min ga tagulla.
2. The yankan ciyar gudun:
Gudun ciyarwa wani abu ne mai mahimmanci daidai daidai wanda ke ƙayyade aikin mashin ɗin lafiya da inganci.Yana nufin kusancin tafiye-tafiye tsakanin kayan aiki da kayan aiki.Don masu yankan hakora masu yawa, tun da kowane haƙori yana shiga cikin aikin yankan, kauri na aikin da za a yanke ya dogara da ƙimar abinci.Kauri daga cikin yanke zai iya rinjayar rayuwar mai yankan niƙa. Don haka yawan abincin da ya wuce kima zai iya haifar da raguwa ko kayan aiki ya karye.
Vf = Fz *Z* N
Gudun ciyarwar Vf, Raka'a mm/min
Fz-feed alkawari, Raka'a mm/r
Z-Yanke hakora
N-Cutter jujjuya saurin gudu, Raka'a r/min
Daga dabarar da ke sama, kawai muna buƙatar sanin haɗin ciyarwa (yanke adadin) kowane haƙori da saurin juyawa wanda zai iya haifar da saurin ciyarwa.A wasu kalmomi, sanin aikin ciyarwa da saurin ciyar da haƙori, ana iya ƙididdige saurin juyawa cikin sauƙi.
Misali, babban abin yankan karfen niƙa mai sauri, lokacin da diamita mai yankan shine 6 mm, ciyarwar kowane haƙori:
Aluminum 0.051;Tagulla 0.051;Karfe 0.025;Bakin Karfe 0.025
3. Zurfin yankan:
Abu na uku shine zurfin yanke.An iyakance shi ta hanyar yankan adadin kayan aikin aiki, ƙarfin juyawa na CNC, mai yankewa da rigidity na kayan aikin injin.Gabaɗaya, zurfin yankan ƙarshen niƙa na ƙarfe bai kamata ya wuce rabin diamita na abin yanka ba.Don yankan ƙarfe mai laushi, zurfin yankan zai iya zama mafi girma.Ƙarshen niƙa dole ne ya kasance mai kaifi kuma yayi aiki da hankali tare da ƙarshen niƙa chuck, kuma tare da ɗan wuce gona da iri sosai lokacin da aka shigar da kayan aikin.
Xiamen Ruicheng Industrial Design Co., Ltd yana da kwarewa mai yawa akan CNC, jin kyauta don isa gare mu idan kuna da buƙata!
