Inkqubo yokwenziwa kweTungsten Carbide yokuSila iiQuills: Ukusuka kwiPowder ukuya kwisixhobo esichanekileyo.

I-Tungsten carbide quill quills zizixhobo ezibalulekileyo kwintsimi yokugaya okuphezulu, kwaye ukusebenza kwabo okungaqhelekanga kubangelwa iinkqubo ezibalaseleyo zokuvelisa. Uhambo olusuka kwi-micron-level powder ukuya kwisixhobo esichanekileyo lubandakanya uchungechunge lweNkqubo elawulwa ngokucokisekileyo.

Ukwahlulahlula kwezinto ezikrwada kunye noKuxutywa

Ukuveliswa kuqala ngomgubo we-tungsten carbide okhethiweyo kunye ne-cobalt powder. I-Cobalt isebenza njengesigaba se-binder, kwaye umxholo wayo uchaphazela ngokuthe ngqo ukuqina kwemveliso yokugqibela kunye nokuqina. Ngokuqhelekileyo, umxholo we-cobalt usuka kwi-6% ukuya kwi-12%, ulungelelaniswa ngokuchanekileyo ngokweemfuno ezithile zesicelo. Ezi powders-level-level powders zimanzi-zixutywe kwii-mills zebhola ukuze kuqinisekiswe ukuhanjiswa okufanayo kwinqanaba le-molecular.

Inkqubo yokuqulunqa

I-slurry edibeneyo i-spray-yomiswe kwiigranules ezihamba ngokukhululekileyo. Emva koko, itekhnoloji yokucinezela ye-isostatic echanekileyo echanekileyo isetyenziselwe ukucinezela izinto kuxinzelelo lwe-200-300 MPa. Ngeli nqanaba, ubume bejometri esisiseko se-carbide shaft yokugaya yenziwe, kodwa amandla ahlala ephantsi, efuna ukuqhutyelwa phambili.

Inkqubo yeSintering

I-Sintering yinkqubo engundoqo yenkqubo yokuvelisa. Kwiindawo zokutshiza ze-vacuum sintering, iqondo lokushisa lilawulwa ngokuchanekileyo ngaphezu kwendawo yokunyibilika kwe-cobalt (ngokuqhelekileyo i-1400-1500 ° C). Ngesi sigaba, isigaba se-cobalt siyanyibilika kwaye simanzise amasuntswana e-tungsten carbide, enze ibhondi exineneyo ye-metallurgical ngokusebenzisa i-liquid phase sintering. Ulawulo oluchanekileyo lwejiko lokufudumeza kunye nexesha lokubamba kubalulekile ukuqinisekisa ukuxinana okupheleleyo kunye nokukhula okuziinkozo okulawulwayo.

Precision Machining

Ibha yokusila ye-carbide engenanto ingena kwinqanaba lomatshini elichanekileyo, elibalulekileyo ekuqinisekiseni ukuba i-quill yokusila iyahlangabezana neemfuno zokusetyenziswa. I-Benchmark machining yenziwa kuqala kusetyenziswa izisiyi ze-cylindrical ezichaneke kakhulu ezinamavili okusila idayimani ukuseka i-axis yereferensi echanekileyo, enokunyamezelwa kobukhulu obulawulwa ngaphakathi kwe-± 0.01 mm.

Iinkqubo zokusila ezichanekileyo zibandakanya:

1. Ukusetyenzwa kwe-shank yesixhobo: Ukusebenzisa izigridi ezichanekileyo eziphezulu ezinamavili edayimani, okubandakanya ukugawula okurhabaxa, ukugqiba isiqingatha, kunye nokugqiba. Ukugaya ngokukrakra kususa izinto ezigqithisileyo, ukugqiba i-semi-finishing kufeza iimfuno ze-dimensional, kwaye ukugqiba kuqinisekisa uburhabaxa bomhlaba Ra ≤ 0.2 μm. Ukunyamezela i-angle yeTaper yeHSK, CAPTO, kunye nolunye ujongano kufuneka lube ngaphakathi ±30”.

2. Ukusetyenzwa komngxuma opholisayo: Ukusebenzisa izixhobo zokugrumba umngxuma onzulu ngeteknoloji yokomba imipu. Ukuqinisekisa umgangatho wodonga lomngxuma, isantya sokutya (ngokuqhelekileyo i-50-100 mm/min) kunye noxinzelelo lokupholisa (10-15 MPa) kufuneka ilawulwe ngokuchanekileyo. Ukuchaneka kwedayamitha yomngxuma kufuneka kufikelele kwibakala le-H7, ngempazamo yokuqina engagqithiyo kwi-0.02/100 mm.

3. I-Dynamic balancing: Ukusebenzisa oomatshini bokulinganisa abakhethekileyo ukulungelelanisa ukuhanjiswa kobuninzi ngokususa izinto eziphathekayo. Iimfuno ziquka ukufezekisa i-G2.5 ibakala lokulinganisela kunye ne-residual unbalance ngaphantsi kwe-1 g · mm / kg kwisantya esiphezulu sokusebenza.

Ukuhlolwa koMgangatho

Ukuhlolwa kokugqibela kubandakanya ukulungelelanisa oomatshini bokulinganisa imilinganiselo yejometri, i-laser interferometers kwifom kunye nokunyamezela isikhundla, ukulinganisa oomatshini bokuvavanya ukulinganisa okuguquguqukayo, kunye neemicroscopes zetsimbi zohlalutyo lwesakhiwo sezinto eziphathekayo. Kuphela ziimveliso ezidlula lonke uvavanyo olungqongqo ezinokuziswa.

Iyonke inkqubo yokuvelisa idibanisa itekhnoloji eninzi kubandakanya isinyithi somgubo, umatshini ochanekileyo, kunye nonyango lobushushu. Ulawulo oluchanekileyo kwinqanaba ngalinye ngokudibeneyo ligalelo ekusebenzeni okungaqhelekanga kwee-tungsten carbide quill quills. Ngokukodwa kwisigaba sokuchaneka kwe-machining, ukusetyenziswa okubanzi kweteknoloji ye-ultra-hard tool, iteknoloji yokulinganisa ngokuchanekileyo, kunye neteknoloji yokulawula ngokuzenzekelayo iqinisekisa ukuchaneka kokuveliswa kwe-micron-level.

Inkampani yaseZhuzhou iBetter Tungsten Carbide inokubonelela ngekhwalithi ephezulu, ukuchaneka kwe-tungsten carbide quills grind. Linda umfowunelwa wakho.
