Imithambo Yokudrillisa Emhlabeni Emkhulu Ngokuphelele Isivumelwano Esithandekayo Sesilayini

Taizhou Chuang Yuan Machine Tool Co., Ltd. iyasebenza i-Deep Hole Gun Drilling Machines eminyakeni yase-2003 eTaizhou City, Jiangsu Province, China. I-Deep Hole Gun Drilling Machine yethu iyaphakisha izikhumba zokubhala ezinomthwana kusukela ku-2 mm kuya ku-40 mm, ubude bezikhumba kumthwana kuyaphikisana ku-100:1, ububi bokubhala (surface roughness) Ra 0.4–1.6 um, nokuhlela kokubhala (positioning accuracy) yoku-0.01 mm ngasendlini yesi-300 mm. Ispindle speeds iyaphikisana ku-6,000 rpm nesifanayo sesibhali (coolant pressure) sokuphikisana ku-100 bar, ngakho-ke izikhumba ezinde ziyabhala ngomlando wodwa (one pass) ngaphandle kokubhala ngamaphepha (peck drilling). Kwezokwenza i-hydraulic cylinder, abathengi babhala izikhumba zokubhala zezindilinga zokubhala (deep holes) zomdlalo we-800 mm emagqabeni we-45 steel ngomdlalo we-18 minithi ngendawo, okuthintekile ukunciphisa isikhathi sokubhala (cutting cycle time) ngo-35%. Kwezokwenza amafomu (mold making), indawo yezinkampani zokwenza amafomu eJalimane (German tool shop) iyasebenzisa i-Deep Hole Gun Drilling Machine yethu ukwenza amaqhina ombili (water lines) omdlalo we-600 mm emagqabeni we-1.2344 steel noma kufana nokuhlela kokubhala (concentricity) okungaphansi kuka-0.02 mm, okuvula ukubhala kabusha (secondary reaming). Kwezokwenza amaphoyinti esihlangu (medical implant production), umthengi weSwisi ubhala izikhumba zomdlalo we-3 mm ngemagqaba yomdlalo we-120 mm yomthwana we-titanium ngaphandle kokugqibela (no deflection), okuhlela ukubhala (tolerance) ngaphansi kuka-0.015 mm.

Imibuzo Evame Ukubuzwa

Izinto ziziphi okufanele zihlanganise kwi-Deep Hole Gun Drilling Machine yakho?

I-Deep Hole Gun Drilling Machine yethu ihlanganisa i-carbon steel, i-alloy steel, i-stainless steel, i-cast iron, i-aluminum, i-copper, i-titanium, ne-Inconel. Umzekelo, iyahlula izikhumba zesikhumba sezinkampani ze-titanium ezingama-3 mm ngokuphakathi kwezinkampani ezingama-120 mm, nezikhumba ezingama-800 mm kwezinkampani ze-45 steel. Ukukhula okuphezulu kuka-HRC 42 kuyasebenza. Uma izinto ziyinkampani ezinkulu, sizomkonza ukusebenzisa i-gun drills ephakanyisiwe ngokwesibonelo esikhethekileyo nezindlela zokubeka okuthathelwe ngokuhambisana. Aba-engineer bethu bakhuphela izindlela zokuhlula ngokwesithembiso sokuthi uyilungiselela noma yini lezinto nokubhala kwezikhumba.

Ukuchaza ukuthi ubude obuphezulu bokuhlula kunobubanzi bokuhlula kubani?

I-machine iyasebenzisa ububanzi bezikhumba ezingama-2 mm kuya kuma-40 mm, nokulinganisa ubude nobubanzi kuya kuma-100:1. Uma ububanzi bezikhumba bingama-10 mm, ungahlula kuya kuma-1,000 mm ngokuphakathi kwesikhathi esinye. Ukuhlula kwe-coolant okuphezulu kuka-100 bar kuvumela ukususa amaphakathi ne-ukuthi izikhumba zibe yisikhathi esifanayo. Uma ukulinganisa kubheka kakhulu kuma-100:1, singakwenza i-machine ngokwesibonelo ngokusebenzisa isistimu esikhulu yokuhlula kwe-coolant nezikhumba zokugcina esikhululekile.

Uyayikwenza njani ukuthi izikhumba zibe yisikhathi esifanayo nezinhlobo zezikhumba?

Sibayisebenzisa isikhali sesilika esingavamile, amaphepha esibhakabhaka esihlukile, namabholisikrubu esihlukanisiwe ngokuphelele. Isistimu sesilika esikhulu sithintela amaphutha kusasa, futhi i-Siemens CNC isiqinisekisa izivinini zokufaka ngaphakathi kwemilingo yezingu-0.01 mm. Ngokujwayelekile, ubude lwesikhala lusobala ngaphakathi kwemilingo yezingu-0.1 mm ngemilingo yezingu-800 mm, ubude lwesikhala lwesigubhu ngaphakathi kwemilingo yezingu-0.02 mm, futhi ubude lwesikhala lwesifunda kumlingo yezingu-Ra 0.4 kuya kuma-1.6 um. Yonke imishini iphatha isizathu sokuzimisa ngemilingo yezingu-72 ngaphambi kokuthunywa.

Isikhathi sokulethwa kanye newaranti singakanani?

Amamodeli asebenzayo ayathunywa emaswidi e-30 kuya kuma-45 ngemuva kokuthenga; amamodeli athengiswa ngokulinganisa ayathunywa emaswidi e-60 kuya kuma-75. Sinenza umbono wokugcina ngemilingo yezingu-24, ukufaka ngaphansi kwesikhala, nokufundisa ngolinye. Amapharti okusebenza ashiyekile kuyasebenza ngemilingo yezingu-10. Sinenza ukuthola indlela yokubona isimo ngendlela yokuqonda ngokwesistimu se-CNC, ngakho ke izinkinga zonke ziyasolvwa ngaphandle kokufuna ukufika kulesikhala, ngakho ke ukungafiki kulesikhala kucindeze abasebenzi emazwe angu-20.

Ngakho ke le mishini ingakhelwa ngokulinganisa ukufunda kwezindlela zokusebenza ezithile?

Yebo. Sisikwenza ngokulinganisa ubude bakwe-stroke, ispeed yakwe-spindle, upressha we-coolant, isistimu sokholwa, nokufaka izinto. Isibonelo, sizakwenza imishini yokuqala kwe-German yokwenza amaphutha nesibude se-stroke se-600 mm nokunika ukulinganisa kwakho okuphakeme kakhulu kwe-concentricity okungu-0.018 mm. Singakwenzela ukufaka ukulayisha ngokuzenzakalelayo, ukususa amachip, nokukhokha ukubona izintshayelelo. Aba-engineer bethu bahlawula izithombe zakho nezifoto, emva koko bavumela isikhombiso esihambisana nomthwalo wakho wemali nokuthi kufanele kwenziwe ngokushesha.

ukuhlatywa komgca olude ukuhlatywa komgca olude sesitshati isikhole eside ukugqogqa amaphoyinti imishini yokubhala amaphuzu amaningi ukudrillla izihlangothi ezinde

Isistimu Yokuchitha Okuphezulu Kwezihlangothi Ezinde Ku-100:1

Imishini yethu yokubhala izikhumba eziningi iyasebenza ngokusebenzisa isistimu yokuhlanza esinamandla angaphezu kwe-100 bar, okuyisisekelo sokubhala izikhumba eziningi. Umkhawulo wamandla ukususa amaphutha kusikhumba, ukuchitha isihlangothi sokubhala, nokunqoba ukugcina kwezikhumba okukhuthaza ukuphakanyiswa kwesikhumba nokungafanele kokubhala isikhumba. Lokhu kusiza ekubhaleni ngokusha kanye ngezinhlobo zokubhala eziningi zokubhala kusukela ku-100:1, ngoko ke isikhumba sesi-10 mm singafika ku-1 000 mm ngaphandle kokubhala ngokuphakanyiswa. Kukuprodukha kwezinkampani zokusebenzisa amandla, lokhu kusiza ekubhaleni izikhumba zokuphakama kwe-800 mm emagugu e-45 ngamahora angu-18 ngalinye, okunciphisa isikhathi sokusebenza ngo-35%. Kukudala kwezimakhilasi, kusiza ekubhaleni izikhumba zokuchitha amandla zokuphakama kwe-600 mm emagugu e-1.2344 ngokuphakama kwe-0.018 mm. Isistimu iyashiywa ngomphathi wamandla omkhulu, isistimu yokuchitha, nokulungisa umkhawulo wokufolowa, futhi isebenza nezinhlobo zokuhlanza ezisemajini noma zisemaphutha. Isitanki sokuhlanza sibhekene nokusebenza ngokuphambili, futhi isistimu yokususa amaphutha isiqiniseka ukuthi indawo yokusebenza ibe yisikhathi sokusebenza.

Isistraktcha yomshini oyedwa kusiza ekufinyeleleni kwe-0.01 mm

Imishini yokuqondisa izikhumba eziningi yisakhiwe kusuka kwezinkumbulo zokugcina ezingenamaphuzu, okuyinto efuna ukuthi ishwele amandla okuphatha nokubeka ubuhle obukhulu ngokuphatha kwezinkumbulo eziningi. Amaphuzu aqondiswa ngokupheleleyo nokugcina ngokupheleleyo, futhi amaphuzu aqondiswa ngokupheleleyo amabhasikili akhona ukuthi abeke ubuhle obukhulu bokubeka kwizikhumba ngokuphatha kwe-0.01 mm ngasemhlabathini we-300 mm futhi ukubeka kabusha kwe-0.005 mm. Isikhumba sisakhiwe ngokupheleleyo futhi sisebenzisa amaphuzu amahle kakhulu, sifika ku-6,000 rpm ngezinhlobo ezincane zokuphatha. Lokhu kubalulekile kuzo zonke izikhumba eziningi, apho izinhlobo ezincane zokuphatha ziyagcina kwezinhlobo ezinkulu ngokuphatha kwezikhumba eziningi. Umkhakha waseJalimani wasebenzisa leshini ukuthi abeke ubuhle obukhulu bokubeka kwizikhumba eziningi zokuphatha kwe-0.018 mm ngasemhlabathini we-600 mm, futhi umkhakha waseSwisi wasebenzisa leshini ukuthi abeke ubuhle obukhulu bokuphatha kwe-0.012 mm ngasemhlabathini we-3 mm ngokuphatha kwezikhumba eziningi zokuphatha kwe-120 mm zezinkumbulo zokuphatha kwe-titanium. Isithembiso sokubeka kufuna ukuthi ubuhle obukhulu bokubeka kwezikhumba kubekwe ngasemhlabathini we-0.02 mm futhi ubuhle bokubeka kwezikhumba kubekwe ngasemhlabathini we-Ra 0.4 ku-1.6 um, okuthintela ukuthi kungafanele ukusebenzisa izikhumba eziningi zokubeka futhi ukuthintela ukuthi kungafanele ukuthintela izindlela zokubeka ngokupheleleyo. Ishini ngisho yonke iyasebenzisa ukubeka ngokupheleleyo futhi ukubeka ngokupheleleyo ngokuphatha kwe-laser interferometer ngaphambi kokuthunywa.
