Litšobotsi tsa elektrode ea rona ea graphite

Litšobotsi tsa ronaelectrode ea graphite:

1. Litheko tse tsitsitseng le tse utloahalang:

Theko ea thepa ea graphite e hloka feela 15% ea molumo o tšoanang oa elektrode ea koporo.Hona joale, graphite e fetohile boitsebiso bo tummeng bakeng sa likopo tsa EDM, tse nang le litšenyehelo tse tlaase le tse tsitsitseng haholoanyane ha li bapisoa le lisebelisoa tsa graphite.

1. Ho seha habonolo le ho sebetsa
2. 4. Boima bo bobebe le bo fokolang
3. Boima ba graphite hangata ke 1.7-1.9g / cm3 (koporo ke makhetlo a 4-5 ho feta a graphite).Ha ho bapisoa le li-electrode tsa koporo, li-electrode tsa graphite li tla fokotsa mojaro oa mochini nakong ea ts'ebetso ena.E loketse ho feta ho sebelisa hlobo e kholo.
4. 5. Ts'ebetso e ntle ea ho itšeha
5. Ha ho bapisoa le lisebelisoa tsa tšepe, molumo oa graphite o etselitsoe ho ba tlaase.E na le ts'ebetso e ntle ea ts'ebetso ea mochini.
6. 6. Phello ea ho kopanya
7. Enke ea lehlohlojane e ka kopanngoa ka sekhomaretsi, e bolokang nako le litšenyehelo tsa thepa.
8. 7. Ho hanyetsa ho phahameng
9. The resistivity (ER) e etsa qeto ea ho hanyetsa ha thepa ho phalla ha hona joale.A tlaase resistivity bolela conductivity.

Graphite e na le thepa e ntle ea ho sebetsa ka mochini.Lebelo la machining la li-electrode tsa graphite le phahame ka makhetlo a 2-3 ho feta li-electrode tsa koporo.Ka nako e ts'oanang, ha ho hlokahale hore u tšoenyehe ka li-burrs ka mor'a ho sebetsa ha graphite.

3. Coefficient e tlase ea ho atolosa mocheso

Sebaka se qhibilihang sa koporo ke 1080 ℃, ha CTE ea graphite e le 1/30 feela ea koporo ho 3650 ℃.E na le ts'ebetso e tsitsitseng haholo esita le ka mocheso o futhumetseng.Esita le ts'ebetsong ea li-electrode tsa platinum, li-electrode tsa graphite li na le melemo e mengata.
