About Dry Cutting

1. Chii chinonzi dry cutting technology
Nekuvandudzwa kweruzivo rwezvakatipoteredza pasi rose uye nekuwedzera kuomesera zvinodiwa nemitemo nemirairo yekuchengetedzwa kwezvakatipoteredza, kuipa kweKucheka mvura yemvura pane zvakatipoteredza kuri kuramba kuchioneka. Maererano nenhamba, makore makumi maviri gare gare, mutengo weKucheka mvura inenge isingasviki 3. % yemutengo weiyo workpiece.Parizvino, mumabhizinesi ekugadzira kugadzirwa kwepamusoro, mutengo weKucheka mvura yekupa, kugadzirisa uye kudzokorodza pamwe chete ichaverengera 13% -17% yemutengo wekugadzira weiyo workpiece, nepo mutengo wekucheka maturusi uchingoverengera 2% -5% ,.Inenge 22% yemari yose ine chokuita neKucheka mvura inodhura yeKucheka mishonga yemvura.Dry cutting imhando ye machining nzira inoshandiswa kuchengetedza zvakatipoteredza uye kuderedza mari pasina kushandisa Cutting fluid uchiziva uye pasina inotonhorera.
Dry yekucheka haisi kungorega kushandisa Kucheka mvura, asi kuve nechokwadi chekushanda kwepamusoro, kugadzirwa kwepamusoro, kusimba kwechigadzirwa chepamusoro uye kuvimbika kwekucheka kwekucheka paunenge uchimira kushandisa Cutting fluid, iyo inoda kushandiswa kwekucheka zvishandiso nekushanda kwakanaka.Machine zvishandiso uye zvivako zvekubatsira zvinotsiva basa reKucheka mvura mukucheka kwechinyakare kuti uwane kucheka kwechokwadi kwakaoma.2.Hunhu hwekuoma kutema tekinoroji
① Machipisi akachena, haana kusvibiswa, uye ari nyore kudzokorodza nekurasa. kupatsanura mudziyo pakati Kucheka mvura uye machipisi uye inoenderana midziyo yemagetsi inosiiwa.Chishandiso chemuchina chakabatana muchimiro uye chinotora nzvimbo shoma.④ Hachizokonzeresa kusvibiswa kwezvakatipoteredza.⑤ Hachizokonzeresa tsaona dzekuchengetedza uye tsaona dzemhando ine chekuita neKucheka mvura.
3. Nezvekucheka zvishandiso
① Chishandiso chinova chakanyanya kupisa tembiricha kuramba uye chinogona kushanda pasina Kucheka mvura.New hard alloys, polycrystalline ceramics, uye CBN zvinhu ndizvo zvinofarirwa zvekucheka maturusi akaoma.② Iko friction coefficient pakati pechip nechombo inofanira kudzikiswa zvakanyanya sezvinobvira (nzira inonyanya kushanda ndeyekupfekedza mudziyo wepamusoro), uchiperekedzwa. nechakanaka chekubvisa chekushandisa chimiro chekudzikisa kuunganidzwa kwekupisa. ③ Maturusi ekucheka akaomeswa anofanirawo kuva nesimba rakakwirira uye kusimba kwekuita kupfuura maturusi ekucheka akanyorova.
4. Tool zvinhu
Coating materialsKupfeka kunoshanda sechivharo chekupisa nekuti ine yakadzikira kupisa conductivity pane chishandiso substrate uye workpiece zvinhu.Naizvozvo, maturusi aya anotora kupisa kushoma uye anogona kumira tembiricha yepamusoro yekucheka.Zvingave mukutenderedza kana kugaya, maturusi akavharidzirwa anobvumira yakakwirira yekucheka paramita pasina kudzikisa chishandiso life.Thinner coatings ine zvirinani kuita pasi pekuchinja kwetembiricha panguva yekucheka kwekubata zvichienzaniswa nekukora machira.Izvi zvinodaro nekuti machira akatetepa ane kuderera kwekunetseka uye haanyanyi kutsemuka.Kucheka kwakaoma kunogona kuwedzera hupenyu hwezvishandiso kusvika ku40%, ndosaka machira emuviri achiwanzo shandiswa kupfekedza maturusi edenderedzwa nekuisa milling.
cermetCermets inogona kumira tembiricha yekucheka yakakwira kupfuura yakajairwa ma alloys akaomeswa, asi inoshaya kupikisa kweakaoma alloys, kuomarara panguva yepakati kusvika kune inorema machining, uye simba panguva yakaderera yekumhanya uye yakakwirira mareti ekudya.Nekudaro, ine zvirinani yakakwirira-tembiricha uye inopfeka kuramba pasi peyakanyanya-kumhanya yakaoma yekucheka, kureba kwenguva, uye nani pamusoro pekupedzisira kweyakagadziriswa workpiece.Kana ichishandiswa kugadzira zvakapfava uye viscous zvinhu, zvakare ine yakanaka kuramba kune chip kuvaka uye yakanaka yepamusoro mhando.Cermets inonyanya kunetseka kushushikana kunokonzerwa nekutyoka uye chikafu kana ichienzaniswa neasina kuvharwa maaloyi akaomarara ane machira ari nani.Naizvozvo, inonyanya kushandiswa kune yakakwiriraprecision workpieces uye inoenderera kucheka mamiriro ane yepamusoro yepamusoro mhando.
Ceramics
Kugadzikana, inokwanisa kugadzirisa pahupamhi hwekucheka uye inogara kwenguva yakareba.Pure alumina inogona kumira tembiricha yakanyanya, asi kusimba kwayo nekuomarara kwakadzikira.Kana mamiriro ekushanda asina kunaka, zviri nyore kuputsa.Kuwedzera musanganiswa wealumina kana titanium nitride kunogona kuderedza kunzwisiswa kweceramics kuti iparare, kunatsiridza kusimba kwavo, uye kunatsiridza kupikisa kwavo.
CBN zvishandisoCBN chinhu chakaomesesa chekushandisa, icho chakanyanya kukodzera kugadzira michina nekuoma kwakakwira kupfuura HRC48.Iyo ine yakanyanya kunaka tembiricha kuomarara - kusvika 2000 ℃, kunyangwe iine yakakwira simba rekuita uye inopwanya kuramba kupfuura Ceramic banga.

CBN ine yakaderera thermal conductivity uye yakakwirira yekumanikidza simba, uye inokwanisa kumira nekupisa kwekucheka kunogadzirwa nekumhanya kukuru kwekucheka uye negative rake angle.Nekuda kwekushisa kwakanyanya munzvimbo yekucheka, iyo workpiece inopfava, iyo inobatsira kuumba machipisi.
Panyaya yekuoma kutendeuka kwakaomeswa maworkpieces, maturusi eCBN anowanzo shandiswa kutsiva maitiro ekukuya nekuda kwekugona kwavo kuwana kurongeka kwepamusoro uye kupera kwepamusoro.Zvishandiso zveCBN uye maturusi eceramic akakodzera kuomesa kutendeuka uye kumhanyisa-kumhanya.

Polycrystalline dhaimani, seyakaomesesa yekucheka mudziyo wemidziyo, haipfeki.Welding PCD zvimedu pane yakaoma alloy blades inogona kuwedzera simba radzo uye kukanganiswa kwemaitiro, uye hupenyu hwavo hwematurusi hunopeta ka100 kupfuura hwemashizha akaoma alloy.
Nekudaro, kuwirirana kwePCD kwesimbi muFerrous kunoita kuti rudzi urwu rwechishandiso rungokwanisa kugadzira zvisiri-ferrous zvinhu.Uye zvakare, PCD haigone kumira tembiricha yakakwira munzvimbo yekucheka inopfuura 600 ℃, saka, haigone kucheka zvinhu zvine kuoma kwakanyanya uye ductility.
Zvishandiso zvePCD zvinonyanya kukodzera kugadzirisa simbi dzisina-ferrous, kunyanya yakakwira silicon aruminiyamu alloys ane friction yakasimba.Kushandisa inopinza yekucheka mipendero uye hombe rake angles kucheka zvakanaka zvinhu izvi, kuderedza kucheka kudzvanywa uye chip kuvaka.
