Indlela yokugcina i-Aluminiyam ye-CNC yokusika i-Fluid kuBomi beSixhobo esiLide kunye ne-Swarf ecocekileyo

 PFT, Shenzhen

Ukugcina i-aluminiyam eyi-CNC yokusika imo yolwelo ichaphazela ngokuthe ngqo ukunxitywa kwesixhobo kunye nomgangatho we-swarf. Olu phononongo luvavanya iiprothokholi zolawulo lwe-fluid ngokusebenzisa iimvavanyo zomatshini ezilawulwayo kunye nohlalutyo lwe-fluid. Iziphumo zibonisa ukuba ukujongwa kwe-pH okungaguqukiyo (uluhlu ekujoliswe kulo 8.5-9.2), ukugcina ugxininiso phakathi kwe-7-9% usebenzisa i-refractometry, kunye nokuphumeza ukuhluzwa kwezigaba ezimbini (40µm elandelwa yi-10µm) ukwandisa ubomi besixhobo nge-avareji ye-28% kunye nokunciphisa ukunamathela kwe-swarf ngama-73% xa kuthelekiswa nolwelo olungalawulwayo. I-oil tramp skimming rhoqo (> 95% ukususwa ngeveki) ikhusela ukukhula kwebhaktheriya kunye nokungazinzi kwe-emulsion. Ulawulo olusebenzayo lwe-fluid lunciphisa iindleko zezixhobo kunye nexesha lokunciphisa umatshini.

1. Intshayelelo

I-CNC yokwenza i-aluminiyam ifuna ukuchaneka kunye nokusebenza kakuhle. Ulwelo lokusika lubalulekile ekupholiseni, ukuthambisa, kunye nokukhutshwa kwetshiphu. Nangona kunjalo, ukuthotywa kolwelo-okubangelwa kungcoliseko, ukukhula kwebhaktheriya, ukukhukuliseka koxinzelelo, kunye nokuqokelelwa kweoyile yetramp - kukhawulezisa ukunxitywa kwesixhobo kwaye kubeke esichengeni ukususwa kwe-swarf, okukhokelela ekwenyukeni kweendleko kunye nexesha lokuphumla. Ngo-2025, ukugcinwa kakuhle kolwelo kuhlala kungumngeni ongundoqo wokusebenza. Olu phononongo lulinganisa impembelelo yeeprothokholi ezithile zogcino kubomi obude besixhobo kunye neempawu ze-swarf kwimveliso ephezulu ye-aluminium ye-CNC.

2. Iindlela

2.1. Uyilo loMfuniselo kunye noMthombo weDatha
Iimvavanyo zoomatshini ezilawulwayo zenziwa kwiiveki ze-12 kwii-5 ezifanayo ze-CNC mills (Haas VF-2) processing 6061-T6 aluminium. I-semi-synthetic cutting fluid (Brand X) yasetyenziswa kubo bonke oomatshini. Umatshini omnye usebenze njengolawulo ngokulungiswa okusemgangathweni, okusebenzayo (utshintsho lolwelo kuphela xa lubonakalisiwe ngokubonakalayo). Ezinye ezine ziphumeze iprothokholi ecwangcisiweyo:

• Ugxininiso:Ukulinganisa imihla ngemihla usebenzisa i-digital refractometer (i-Atago PAL-1), ilungiswe kwi-8% ± 1% kunye ne-concentrate okanye i-DI yamanzi.

• pH:Ukubekwa esweni yonke imihla kusetyenziswa imitha ye-pH elinganisiweyo (Hanna HI98103), egcinwe phakathi kwe-8.5-9.2 kusetyenziswa izongezo ezivunywe ngumenzi.

• Uhluzo:Uhluzo lwenqanaba elimbini: 40µm ingxowa yokucoca ilandelwa sisihluzo sekhatriji eyi-10µm. Izihlungi zitshintshile ngokusekelwe kukwahlukana koxinzelelo (≥ 5 psi ukwanda).

• Ukususwa kweOli yeTramp:Ukutyibiliza ngebhanti kuqhutywa ngokuqhubekayo; umphezulu we-fluid uhlolwe yonke imihla, ukusebenza kakuhle kwe-skimmer kuqinisekiswe ngeveki (> 95% ekujoliswe kuyo ekususeni).

• Make-up Fluid:Kuphela i-fluid exutywe ngaphambili (kwi-8% yoxinaniso) esetyenziselwa ukunyusa.

2.2. Ukuqokelelwa kwedatha kunye neZixhobo

• Isinxibo sesixhobo:I-Flank wear (i-VBmax) ilinganiswe kwiindawo eziphambili zokusika ze-3-flute carbide end mills (Ø12mm) kusetyenziswa i-microscope yomenzi wesixhobo (Mitutoyo TM-505) emva kweendawo ezingama-25. Izixhobo zitshintshwe kwi-VBmax = 0.3mm.

• Uhlalutyo lwe-Swarf:I-swarf iqokelelwa emva kwebhetshi nganye. "Ukunamathela" kulinganiswe kwisikali se-1 (i-free-flowing, eyomileyo) ukuya kwi-5 (i-clumped, i-greasy) ngabaqhubi aba-3 abazimeleyo. Amanqaku angumndilili arekhodiweyo. Ukuhanjiswa kobungakanani beChip kuhlalutywa ngamaxesha athile.

• Imeko yolwelo:Iisampulu zamanzi zeveki ezihlalutywa yilebhu ezimeleyo yokubala ibhaktheriya (CFU / mL), umxholo weoli ye-tramp (%), kunye nokuqinisekiswa kwe-concentration / pH.

• Ixesha lokuphumla koomatshini:Irekhodishelwe utshintsho lwezixhobo, iijam ezinxulumene neswarf, kunye nemisebenzi yokugcinwa kwamanzi.

3. Iziphumo & Uhlalutyo

3.1. Tool Life Extension
Izixhobo ezisebenza phantsi kweprothokholi yolungiso olucwangcisiweyo bezisoloko zifikelela kumanani aphezulu ngaphambi kokuba zifune ukutshintshwa. Umyinge wobomi besixhobo unyuke nge-28% (ukusuka kwi-175 inxalenye / isixhobo ekulawuleni ukuya kwi-224 inxalenye / isixhobo phantsi kweprotocol). Umzobo 1 ubonisa uthelekiso oluqhubekayo lweflank.

3.2. UkuPhuculwa koMgangatho weSwarf
Iireyithingi zokuncamathela kwe-Swarf zibonise ukuhla okumangalisayo phantsi kweprotocol elawulwayo, i-avareji ye-1.8 xa kuthelekiswa ne-4.1 yolawulo (ukunciphisa i-73%). Ulwelo olulawulwayo luvelise i-drier, ii-chips zegranular ezingaphezulu (Umfanekiso wesi-2), uphucula kakhulu ukukhutshwa kunye nokunciphisa i-jam yomatshini. Ixesha lokuphumla elinxulumene nemiba ye-swarf lehle ngama-65%.

3.3. Ukuzinza kolwelo
Uhlalutyo lwaseLab luqinisekise ukusebenza kweprothokholi:

• Amanani ebhaktheriya ahlala engaphantsi kwe-10³ CFU/mL kwiinkqubo ezilawulwayo, ngelixa ulawulo ludlule kwi-10⁶ CFU/mL ngeveki yesi-6.

• Umxholo weoli ye-tramp i-avareji <0.5% kwi-fluid elawulwayo vs.> 3% kulawulo.

• Ugxininiso kunye ne-pH yahlala izinzile phakathi kweenkalo ekujoliswe kuzo kumanzi alawulwayo, ngelixa ulawulo lubonise ukukhukuliseka okubonakalayo (ugxininiso lwehla ukuya kwi-5%, i-pH ewela kwi-7.8).

4. Ingxoxo

4.1. Iinkqubo zokuqhuba iziphumo
Uphuculo luvela ngokuthe ngqo kumanyathelo olondolozo:

• Ukugxila okuZinzileyo kunye ne-pH:Ukuqinisekisa ukuthambisa okungaguqukiyo kunye nokuthintela ukubola, ukunciphisa ngokuthe ngqo ukuguga kunye nokunxiba kweekhemikhali kwizixhobo. I-pH ezinzileyo ithintele ukuchithwa kwe-emulsifiers, ukugcina ingqibelelo yamanzi kunye nokuthintela "ukumuncu" okwandisa ukunamathela kwi-swarf.

• Uhluzo olusebenzayo:Ukususwa kweengqungquthela zetsimbi ezintle (iintlawulo ze-swarf) ezincitshisiweyo zokugqoka izixhobo kunye nezixhobo zokusebenza. Ulwelo lwesicoci nalo luqukuqela ngokusebenzayo ngakumbi ukupholisa kunye nokuhlamba iitshiphu.

• Ulawulo lweoyile yeTramp:I-oyile ye-tramp (ukusuka kwi-lube, i-hydraulic fluid) iphazamisa i-emulsions, inciphisa ukusebenza kakuhle kokupholisa, kwaye inika umthombo wokutya kwiibhaktheriya. Ukususwa kwayo kwakubalulekile ekuthinteleni uburhalarhume kunye nokugcina uzinzo lwamanzi, igalelo elibalulekileyo kwi-swarf ecocekileyo.

• Uxinzelelo lwebhaktheriya:Ukugcina ugxininiso, i-pH, kunye nokususa iibhaktheriya ezilambisa ioyile, ukuthintela iiasidi kunye ne-slime abayivelisayo ethoba ukusebenza kolwelo, izixhobo zokubola, kwaye ibangele ivumba elibi / i-swarf encangathi.

4.2. Unyino kunye neempembelelo eziSebenzayo
Olu pho nonongo lugxininise kulwelo oluthile (i-semi-synthetic) kunye ne-aluminium alloy (6061-T6) phantsi kweemeko zokuvelisa ezilawulwayo kodwa ezinokwenyani. Iziphumo zinokwahluka kancinane ngolwelo olwahlukileyo, ialloyi, okanye iiparamitha zomatshini (umz., umatshini onesantya esiphezulu kakhulu). Nangona kunjalo, imigaqo ephambili yolawulo lokuxinana, ukubeka iliso kwe-pH, ukuhluzwa, kunye nokususwa kweoyile yetramp iyasebenza kwihlabathi liphela.

• Iindleko zokuphumeza:Ifuna utyalo-mali kwizixhobo zokubeka iliso (i-refractometer, imitha ye-pH), iinkqubo zokuhluza, kunye ne-skimmers.

• Umsebenzi:Ifuna ukuhlolwa kwemihla ngemihla kunye nohlengahlengiso ngabaqhubi.

• I-ROI:Ukunyuka okubonakalisiweyo kwe-28% kubomi besixhobo kunye ne-65% yokunciphisa ixesha lokuphumla elinxulumene ne-swarf linika imbuyekezo ecacileyo kutyalo-mali, ukulinganisa iindleko zenkqubo yokulondoloza kunye nezixhobo zokulawula ulwelo. Ukwehliswa kwamaza okulahlwa kolwelo (ngenxa yobomi obude be-sump) lugcino olongezelelweyo.

5. Isiphelo

Ukugcina i-aluminium ye-CNC yokusika i-fluid ayikhethi ukuba isebenze ngokufanelekileyo; yindlela yokusebenza ebalulekileyo. Olu phononongo lubonisa ukuba iprotocol ecwangcisiweyo egxile kugxininiso lwemihla ngemihla kunye nokujongwa kwe-pH (izinto ekujoliswe kuzo: 7-9%, pH 8.5-9.2), ukuhluzwa kwamanqanaba amabini (40µm + 10µm), kunye nokususwa kwe-oyile yetramp enobundlongondlongo (>95%) kuzisa iinzuzo ezibalulekileyo, ezinokulinganiswa:

1. Ubomi besixhobo esandisiweyo:Ukunyuka komyinge wama-28%, ukunciphisa ngokuthe ngqo iindleko zezixhobo.

2. Isicoci seSwarf:I-73% yokunciphisa ukunamathela, ukuphucula kakhulu ukukhutshwa kwe-chip kunye nokunciphisa i-jams yomatshini / ixesha lokuphumla (ukunciphisa i-65%).

3. Ulwelo oluzinzileyo:Ukukhula kwebhaktheriya kunye nokugcina ingqibelelo ye-emulsion.

Iifektri kufuneka zibeke phambili ukuphunyezwa kweenkqubo zolawulo olululo. Uphando lwexesha elizayo lunokuphonononga impembelelo yeepakethe ezithile ezongezelelweyo phantsi kwale protocol okanye ukuhlanganiswa kweenkqubo zokujonga ulwelo oluzenzekelayo lwexesha lokwenyani.
