Maitiro ekuchengeta Aluminium CNC Yekucheka Fluid Yehurefu Chishandiso Hupenyu uye Yakachena Swarf

 PFT, Shenzhen

Kuchengeta yakakwana aluminium CNC yekucheka mamiriro emvura inokonzeresa kupfeka kwechishandiso uye swarf mhando. Ichi chidzidzo chinoongorora fluid manejimendi maprotocol kuburikidza nekudzora machining miedzo uye kuongororwa kwemvura. Mhedzisiro inoratidza kuti kunoenderana pH yekutarisa (chinangwa chiyero 8.5-9.2), kuchengetedza kutarisisa pakati pe7-9% uchishandisa refractometry, uye kuita mbiri-nhanho kusefa (40µm inoteverwa ne10µm) inowedzera hupenyu hwematurusi neavhareji ye28% uye kuderedza swarf kunamira ne73% zvichienzaniswa nemvura isingadzorwe. Nguva dzose tramp mafuta skimming (> 95% kubviswa kwevhiki nevhiki) inodzivirira kukura kwebhakitiriya uye kusagadzikana kwemulsion. Kushanda kwemvura manejimendi kunoderedza mutengo wekushandisa uye kuderera kwemuchina.

1. Nhanganyaya

CNC machining yealuminium inoda kunyatsoita uye kunyatsoshanda. Kucheka zvinwiwa zvakakosha pakutonhodza, kuzora, uye kubvisa chip. Nekudaro, kushatisa kwemvura - kunokonzerwa nekusvibiswa, kukura kwebhakitiriya, kudonhedza, uye kuunganidzwa kwemafuta - inomhanyisa kupfeka kwezvishandiso uye kukanganisa kubviswa kweswafi, zvichikonzera kuwedzera kwemitengo uye kuderera. Pakazosvika 2025, kugadzirisa kugadzirisa kwemvura kunoramba kuri dambudziko rekushanda. Ichi chidzidzo chinoyera kukanganiswa kweiyo chaiyo yekuchengetedza mapuroteni pahurefu hwechishandiso uye swarf hunhu mune yakakwira-vhoriyamu aluminium CNC kugadzirwa.

2. Nzira

2.1. Yekuedza Dhizaini & Dhata Source
Kudzora machining bvunzo kwakaitwa kwemavhiki gumi nemaviri pane mashanu akafanana CNC mills (Haas VF-2) kugadzirisa 6061-T6 aluminium. Semi-synthetic yekucheka fluid (Brand X) yakashandiswa pamichina yese. Muchina mumwe wakashanda sekutonga neyakajairwa, reactive gadziriso (fluid inoshanduka chete kana ichioneka yakaderedzwa). Vamwe vana vakaita chirongwa chakarongeka:

• Concentration:Kuyerwa zuva nezuva uchishandisa digital refractometer (Atago PAL-1), yakagadziridzwa kusvika 8% ± 1% ine concentrate kana DI mvura.

• pH:Inotariswa zuva nezuva uchishandisa yakaribrated pH mita (Hanna HI98103), inochengetwa pakati pe8.5-9.2 uchishandisa mugadziri-akatenderwa ekuwedzera.

• Sefa:Dual-stage filtration: 40µm bhegi sefa inoteverwa ne10µm cartridge filter. Mafirita akashandurwa zvichienderana nekudzvanywa kusiyanisa (≥ 5 psi kuwedzera).

• Tramp Oiri Kubviswa:Bhandi skimmer yakashanda nguva dzose; mvura yemvura yakatariswa zuva nezuva, skimmer inoshanda yakasimbiswa vhiki nevhiki (> 95% yekubvisa chinangwa).

• Make-up Fluid:Chete pre-yakasanganiswa fluid (pa 8% concentration) inoshandiswa pakuwedzera-ups.

2.2. Kuunganidza Data & Zvishandiso

• Tool Wear:Flank wear (VBmax) yakayerwa pamakona ekutanga e3-flute carbide end mill (Ø12mm) uchishandisa maikorosikopu yemuchina (Mitutoyo TM-505) mushure mezvikamu makumi maviri neshanu zvega zvega. Zvishandiso zvakatsiviwa paVBmax = 0.3mm.

• Swarf Analysis:Swarf inounganidzwa mushure mebatch yega yega. "Kunamira" kwakayerwa pachiyero che 1 (chisina-kuyerera, chakaoma) kusvika pa5 (clumped, greasy) ne3 vanozvimiririra vanoshanda. Avhareji yezvibodzwa zvakarekodhwa. Kugovera saizi yechip kunoongororwa nguva nenguva.

• Fluid Condition:Weekly fluid samples akaongororwa neakazvimiririra lab yebhakitiriya kuverenga (CFU/mL), tramp mafuta emukati (%), uye concentration/pH verification.

• Machine Downtime:Yakarekodhwa nokuda kwechinjo dzematurusi, jamu dzine chekuita neswarf, uye mabasa ekugadzirisa mvura.

3. Migumisiro & Analysis

3.1. Chishandiso Hupenyu Kuwedzera
Zvishandiso zvinoshanda pasi peiyo yakarongwa yekuchengetedza protocol zvakagara zvichisvika kune yakakwira zvikamu zvisati zvada kutsiviwa. Ivhareji yehupenyu hwekushandisa yakawedzera ne 28% (kubva pazvikamu zve 175 / chigadziro mukutonga kusvika kune zvikamu zve224 / chishandiso pasi peprotocol). Mufananidzo 1 unoratidza kufambira mberi kwekupfeka kweflank kuenzanisa.

3.2. Swarf Quality Kuvandudza
Swarf stickiness ratings yakaratidza kuderera kunoshamisa pasi peprotocol yakagadziriswa, inosvika 1.8 kana ichienzaniswa ne4.1 yekutonga (73% kuderedza). Mvura inogadziriswa inogadzirwa yakaoma, yakawanda granular machipisi (Mufananidzo 2), inovandudza zvakanyanya kubuda uye kuderedza jamu yemuchina. Nguva yekuzorora ine chekuita nenyaya dzeswarf yakadzikira ne65%.

3.3. Fluid Kugadzikana
Ongororo yeLab yakasimbisa kushanda kweprotocol:

• Huwandu hwehutachiona hwakaramba huri pazasi 10³ CFU/mL mumasisitimu akatarisirwa, nepo kutonga kwakapfuura 10⁶ CFU/mL nevhiki 6.

• Tramp oiri yemukati yakaenzana <0.5% mune yakagadziriswa fluid vs.> 3% mukutonga.

• Concentration uye pH yakaramba yakagadzikana mukati mezvinangwa zvemvura inogadziriswa, nepo kutonga kwakaratidza kudonha kwakakosha (concentration inodonha kusvika 5%, pH inowira ku7.8).

4. Kukurukurirana

4.1. Mechanism Driving Results
Iko kunatsiridza kunobva zvakananga kubva kune zviito zvekugadzirisa:

• Yakagadzika Concentration & pH:Ive nechokwadi chakafanana lubricity uye corrosion inhibition, inodzikisa zvakananga abrasive uye makemikari kupfeka pamaturusi. Yakagadzika pH yakadzivirira kuparara kwema emulsifiers, kuchengetedza kutendeseka kwemvura uye kudzivirira iyo "souring" inowedzera swarf adhesion.

• Kusefa Kunobudirira:Kubviswa kweakatsetseka simbi particles (swarf fines) yakaderedzwa abrasive kupfeka pamidziyo uye workpieces. Mvura yekuchenesa yaiyererawo zvinobudirira pakutonhodza uye kuwacha machipisi.

• Tramp Oiri Kudzora:Tramp mafuta (kubva munzira lube, hydraulic fluid) inovhiringidza emulsions, inoderedza kutonhora kwakanaka, uye inopa chikafu chekudya kwebhakitiriya. Kubviswa kwayo kwaive kwakakosha kudzivirira rancidity uye kuchengetedza kugadzikana kwemvura, zvichibatsira zvakanyanya kune yakachena swarf.

• Bacterial Suppression:Kuchengeta kutarisisa, pH, uye kubvisa tramp mafuta ane nzara mabhakitiriya, kudzivirira maasidhi uye slime zvavanogadzira izvo zvinosvibisa kuita kwemvura, corrode maturusi, uye kukonzera kunhuhwirira kwakashata / kunamira swarf.

4.2. Kuganhurirwa & Zvinoshanda Zvinoreva
Ichi chidzidzo chakanangana neiyo chaiyo fluid (semi-synthetic) uye aruminiyamu alloy (6061-T6) pasi peanodzorwa asi echokwadi ekugadzira mamiriro. Mibairo inogona kusiana zvishoma nemvura dzakasiyana, alloys, kana machining paramita (semuenzaniso, yakanyanya-kumhanya machining). Nekudaro, iwo musimboti misimboti yekutarisa kudzora, pH yekutarisa, kusefa, uye tramp kubviswa kwemafuta anoshanda pasi rose.

• Mutengo Wekushandisa:Inoda kudyara muzvishandiso zvekutarisa (refractometer, pH mita), mafirita masisitimu, uye skimmers.

• Basa:Inoda kurangwa zuva nezuva cheki uye kugadziriswa nevashandisi.

• ROI:Iyo yakaratidza 28% yekuwedzera muhupenyu hwematurusi uye 65% kuderedzwa kweiyo swarf-inoenderana nenguva inopa kudzoka kwakajeka pakudyara, kugadzirisa mutengo wechirongwa chekugadzirisa uye midziyo yekugadzirisa mvura. Kudzikira mvura yekurasa frequency (nekuda kwehupenyu hurefu hwe sump) kumwe kuponesa.

5. Mhedziso

Kuchengeta aruminiyamu CNC yekucheka mvura haisi sarudzo yekushanda kwakaringana; inzira yakakosha yekushandisa. Ichi chidzidzo chinoratidza kuti chirongwa chakarongeka chinotarisa kutariswa kwemazuva ese uye pH yekutarisa (zvinangwa: 7-9%, pH 8.5-9.2), dual-stage filtration (40µm + 10µm), uye nehukasha kubviswa kwemafuta emutramp (> 95%) inopa zvakakosha, zvinoyerwa mabhenefiti:

1. Hupenyu Hwekushandisa hwakawedzerwa:Avhareji yekuwedzera ye28%, ichidzikisa zvakananga mutengo wekushandisa.

2. Cleaner Swarf:73% kuderedzwa kwekunamatira, zvakanyanya kuvandudza chip evacuation uye kuderedza muchina jams / downtime (65% kuderedza).

3. Yakagadzikana Fluid:Yakadzvinyirirwa kukura kwebhakitiriya uye kuchengetedza emulsion kutendeseka.

Mafekitari anofanirwa kukoshesa kuita zvirongwa zvekutonga kwemvura. Tsvagiridzo yeramangwana inogona kuongorora mabatiro emamwe ekuwedzera mapakeji pasi peiyi protocol kana kubatanidzwa kweautomated real-time fluid yekutarisa masisitimu.
