Za Dry Cutting

1. Kodi luso la kudula kowuma ndi chiyani
Ndi kupititsa patsogolo chidziwitso cha chilengedwe padziko lonse lapansi komanso zofunikira zowonjezereka za malamulo ndi malamulo otetezera chilengedwe, zotsatira zoipa za Kudula madzi pa chilengedwe zikuwonekera kwambiri. Malinga ndi ziwerengero, zaka 20 pambuyo pake, mtengo wa Kudula madziwo udzakhala wosakwana 3 % ya mtengo wa workpiece.Pakali pano, m'mabizinesi opangira zokolola zambiri, mtengo wa Kudula madzi, kukonza ndi kubwezeretsanso pamodzi udzawerengera 13% -17% ya mtengo wamtengo wapatali wa workpiece, pamene mtengo wa zida zodula umangotengera 2% -5% ,.Pafupifupi 22% ya ndalama zonse zokhudzana ndi Kudula madzimadzi ndi mtengo wa Kudula mankhwala amadzimadzi.Kudula kowuma ndi mtundu wa njira yopangira makina omwe amagwiritsidwa ntchito poteteza chilengedwe ndi kuchepetsa ndalama popanda kugwiritsa ntchito Kudula madzi mozindikira komanso popanda ozizira.
Kudula kouma sikungosiya kugwiritsa ntchito Kudula madzi, koma kuonetsetsa kuti ntchito yabwino kwambiri, khalidwe lapamwamba la mankhwala, kukhazikika kwa chida chapamwamba ndi kudalirika kwa njira yodulira pamene mukusiya kugwiritsa ntchito Kudula madzi, komwe kumafuna kugwiritsa ntchito zida zodula ndi ntchito zabwino. maofesi othandizira m'malo ntchito Kudula madzimadzi mu kudula miyambo kukwaniritsa kwenikweni youma kudula.2.Makhalidwe aukadaulo wodula wowuma
① Tchipisi ndi zoyera, zopanda kuipitsa, komanso zosavuta kuzibwezeretsanso ndikutaya.② Zipangizo zodulira madzimadzi, kuchira, kusefera ndi ndalama zofananirako zimasungidwa, makina opangira amakhala osavuta ndipo mtengo wodulira umachepa.③ The chida cholekanitsa pakati Kudula madzimadzi ndi tchipisi ndi lolingana zida zamagetsi zasiyidwa.Chida cha makina ndi chophatikizika ndipo chimatenga malo ochepa.④ Sichidzawononga chilengedwe.⑤ Sichidzayambitsa ngozi zachitetezo komanso ngozi zabwino zokhudzana ndi Kudula madzimadzi.
3. Za zida zodulira
① Chidacho chizikhala ndi kukana kutentha kwambiri ndipo chitha kugwira ntchito popanda Kudula madzimadzi.Ma aloyi atsopano olimba, zoumba za polycrystalline, ndi zida za CBN ndizomwe zimakondedwa pazida zodulira zowuma.② Mkangano wapakati pa chip ndi chidacho uyenera kuchepetsedwa momwe kungathekere (njira yothandiza kwambiri ndikuveka chida pamwamba), limodzi ndi ndi chida chabwino chochotsera tchipisi chochepetsera kutentha.③ Zida zodulira zowuma ziyeneranso kukhala zamphamvu komanso zolimba kuposa zida zonyowa zodulira.
4. Zida zothandizira
❖ kuyanika kumachita ngati chotchinga matenthedwe chifukwa ali otsika kwambiri matenthedwe madutsidwe kuposa chida gawo lapansi ndi workpiece zakuthupi.Choncho, zipangizozi zimatenga kutentha kochepa ndipo zimatha kupirira kutentha kwambiri.Kaya mukutembenuza kapena mphero, zida zokutira zimalola magawo apamwamba odulira popanda kuchepetsa zida life.Thinner zokutira zimakhala ndi ntchito yabwino pansi pakusintha kwa kutentha panthawi yodula poyerekeza ndi zokutira zokulirapo.Izi ndichifukwa choti zokutira zoonda zimakhala ndi kupsinjika pang'ono ndipo sizimakonda kusweka.Kudula kowuma kumatha kukulitsa moyo wa zida mpaka 40%, ndichifukwa chake zokutira zakuthupi zimagwiritsidwa ntchito kwambiri kuvala zida zozungulira komanso zoyikapo mphero.
Ma cermetCermets amatha kupirira kutentha kwambiri kuposa ma aloyi olimba, koma alibe mphamvu yolimbana ndi ma alloys olimba, kulimba panthawi yapakati mpaka makina olemera, komanso mphamvu pakuthamanga kotsika komanso kuchuluka kwa chakudya.Komabe, imakhala ndi kutentha kwapamwamba komanso kukana kuvala pansi pa kudula kowuma kothamanga kwambiri, nthawi yayitali, komanso kumaliza kwabwinoko kwa chogwiriracho.Ikagwiritsidwa ntchito pokonza zinthu zofewa komanso zowoneka bwino, imakhalanso ndi kukana kwa chip buildup komanso mawonekedwe abwino a pamwamba.Ma Cermets amakhudzidwa kwambiri ndi kupsinjika komwe kumachitika chifukwa chakusweka ndi chakudya poyerekeza ndi ma aloyi olimba osakutidwa okhala ndi zokutira bwino.Chifukwa chake, imagwiritsidwa ntchito bwino pamapangidwe apamwamba kwambiri komanso malo odulira mosalekeza okhala ndipamwamba kwambiri.
zadothi
Kukhazikika, wokhoza kukonza pa liwiro lalitali kwambiri ndikukhalitsa kwa nthawi yayitali.Aluminium yoyera imatha kupirira kutentha kwambiri, koma mphamvu ndi kulimba kwake ndizochepa kwambiri.Ngati zinthu zogwirira ntchito sizili bwino, ndizosavuta kuswa.Kuphatikizira kusakaniza kwa alumina kapena titaniyamu nitride kumatha kuchepetsa kukhudzika kwa zoumba kuti zisweka, kuwongolera kulimba kwawo, ndikuwongolera kukana kwawo.
CBN toolsCBN ndi chida cholimba kwambiri, chomwe chili choyenera kwambiri pamakina olimba kwambiri kuposa HRC48.Ili ndi kuuma kwambiri kwa kutentha kwambiri - mpaka 2000 ℃, ngakhale imakhala ndi mphamvu zochulukirapo komanso kukana kusweka kuposa mpeni wa Ceramic.

CBN ili ndi kutsika kwamafuta otsika komanso kulimba kwamphamvu kwambiri, ndipo imatha kupirira kutentha komwe kumapangidwa ndi liwiro lalikulu komanso ngodya yoyipa.Chifukwa cha kutentha kwakukulu m'dera locheka, zinthu zogwirira ntchito zimafewetsa, zomwe zimathandiza kupanga tchipisi.
Pankhani ya zowuma zowuma zowuma, zida za CBN zimagwiritsidwa ntchito m'malo opera chifukwa cha kuthekera kwawo kukwaniritsa zolondola kwambiri komanso kumaliza pamwamba.Zida za CBN ndi zida za ceramic ndizoyenera kutembenuza mowumitsa komanso mphero yothamanga kwambiri.

Polycrystalline diamondi, monga chida cholimba kwambiri chodulira, sichimva kuvala.Kuwotchera magawo a PCD pamasamba olimba a aloyi kumatha kukulitsa mphamvu zawo komanso kukana, ndipo moyo wawo wa zida umaposa 100 kuposa wa masamba olimba a aloyi.
Komabe, kuyanjana kwa PCD kwa chitsulo mu Ferrous kumapangitsa chida chamtunduwu kuti chizitha kukonza zinthu zopanda chitsulo.Kuphatikiza apo, PCD silingathe kupirira kutentha kwambiri m'dera lodulira lopitilira 600 ℃, chifukwa chake, silingathe kudula zida zolimba kwambiri komanso ductility.
Zida za PCD ndizofunikira makamaka pokonza zitsulo zopanda chitsulo, makamaka ma aloyi apamwamba a silicon aluminiyamu omwe amakangana kwambiri.Kugwiritsa ntchito nsonga zakuthwa ndi ngodya zazikuluzikulu kuti mudulire bwino zida izi, kuchepetsa kuthamanga kwa chip ndikumanga kwa chip.
