Isantya esiphezulu vs. High-Efficiency Milling for Aluminium Heat Sinks

Njengoko imfuno yehlabathi yezisombululo eziphezulu ze-thermal ikhula, abavelisiubuso boxinzelelo lokwandisaisinki yobushushu bealuminiyamimveliso.Ukugaya ngesantya esiphezulu semveli ilawula ishishini, kodwa iindlela ezisakhulayo zobuchule obuphezulu zithembisa iinzuzo zemveliso. Olu pho nonongo lulinganisa ukurhweba phakathi kwezi ndlela zisebenzisa idatha ye-machining yomhlaba wangempela, ukujongana nomsantsa obalulekileyo kuphando olusetyenzisiweyo lwamacandelo okupholisa i-elektroniki.

Indlela yokusebenza

1.Uyilo loMfuniselo

●Umsebenzi:Iibhloko ze-aluminium ze-6061-T6 (150×100×25 mm)

●Izixhobo:I-6mm ye-carbide end Mills (3-flute, i-ZrN-coated)

●Lawula iinguqu:

I-HSM: 12,000-25,000 RPM, umthwalo we-chip oqhubekayo

I-HEM: 8,000–15,000 RPM ngothethathethwano oluguquguqukayo (50–80%)

2. Ukuqokelelwa kwedatha

● Uburhabaxa bomphezulu: Mitutoyo SJ-410 iprofilometer (imilinganiselo emi-5/isixhobo sokusebenza)

● Ukunxiba kwesixhobo: I-Keyence VHX-7000 imakroskopu yedijithali (ukunxiba kweflanki >0.3mm = ukusilela)

● Izinga lokuvelisa: Ukulandelela ixesha lokujikeleza kunye ne-Siemens 840D CNC logs

Iziphumo & Uhlalutyo

1.Umgangatho womphezulu

● Indlela: HSM HEM

● Eyona RPM: 18,000 12,000

●Ra (μm):0.4 0.7

Ukugqiba okuphezulu kwe-HSM (iphe<0.05) ihambelana nokucuthwa kokwakhiwa kwe-edge edge kwizantya eziphakamileyo.

2.Ubomi besixhobo

● Izixhobo ze-HSM aziphumelelanga kwi-1,200 yeemitha zomgca xa kuthelekiswa ne-HEM's 1,800 yeemitha

● I-Adhesive wear ilawula ukungaphumeleli kwe-HSM, ngelixa i-HEM ibonisa iipatheni ezinqabileyo

Ingxoxo

1.Iimpembelelo Eziluncedo

●Ngezicelo ezichanekileyo:I-HSM ihlala ikhethwa nangona iindleko eziphezulu zezixhobo

●Ukuveliswa kwevolumu ephezulu:I-HEM ye-15% yexesha lomjikelo okhawulezayo uqinisekisa ukupolisha emva komatshini

2.Imida

● Kungabandakanyi iimeko ze-5-axis machining

● Uvavanyo olulinganiselwe kwizixhobo ze-6mm; iidayimitha ezinkulu zinokutshintsha iziphumo

Ukuqukumbela

I-HSM inikezela ukugqiba okuphezulu komphezulu kwiisinki zobushushu beprimiyamu, ngelixa i-HEM igqwesa kwimveliso yobuninzi. Uphando lwexesha elizayo kufuneka luphonononge iindlela ezixubeneyo ezidibanisa ukupasa kokugqiba kwe-HSM kunye ne-HEM roughing.
