Txheej txheem ntawm Sintered NdFeB Magnets

Cov txheej txheem tsim khoom:
Cov khoom hnyav → Melting & Sawb Casting → Hydrogen Decrepitation → Dav Hlau Milling → Aligning & Nias → Sintering & Annealing → Material Test → Machining → Surface Treatment → Product Inspection → Magnetizing → Packing & Shipping

 

Post processing:
Sab nrauv ntawm cov hlau nplaum feem ntau ua tiav los ntawm qhov tsis muaj qhov sib tsoo (cylindrical hlau nplaum) los yog lub ntsej muag grinder (square hlau nplaum), kom cov hlau nplaum ntxhib muaj qhov tsis tu ncua sab nrauv thiab ncav cuag qhov loj me;

 

Cov txheej txheem txiav yog siv lub pob zeb diamond sab hauv lub voj voog hlais lossis lub tshuab txiav hlau los txiav cov hlau nplaum ua tiav rau hauv cov duab thiab qhov loj me ze rau cov khoom tiav;

 

Cov txheej txheem kev sib tsoo zoo yog siv lub ntsej muag grinder, ob lub tog sib tsoo lossis lwm cov khoom sib tsoo los ua cov hlau nplaum txiav kom tau raws li qhov yuav tsum tau ua ntawm cov khoom tiav;

 

Chamfering yog txheej txheem pretreatment ua ntej electroplating, txhawm rau txo qhov tsis sib xws ntawm cov txheej txheem los ntawm cov ntsiab lus tseem ceeb tam sim no nyob rau ntawm ntug ntawm cov hlau nplaum thaum lub sij hawm electroplating txheej txheem. Vim yog qhov me me thiab cov duab sib txawv ntawm ib txwm sintered Neodymium tiav cov hlau nplaum, cov txheej txheem dawb dov yog qhov tsim nyog tshaj plaws rau cov khoom loj chamfering. Dawb tumbling thiab tiav technologies muaj xws li: vibration tumbling, eddy tam sim no tumbling, centrifugal tumbling, spindle tumbling thiab lwm txoj kev. Ntawm lawv, lub vibratory chim sib tsoo muaj ntau lawm efficiency thiab ceev chamfering ceev, thiab tau dav siv los ntawm sintered Nd-Fe-B hlau nplaum ua manufacturers;

 

Electroplating yog tsim los tiv thaiv txheej txheej ntawm cov hlau nplaum, uas feem ntau ua tiav los ntawm kev plating dawb, thiab rau cov hlau nplaum loj, khib plating yog siv. Cov txheej txheem ntawm sintered Nd-Fe-B hlau nplaum yog muab faib ua Ni plating, Zn plating, phosphating, electrophoresis, alloy plating, composite plating, thiab lwm yam nyob ntawm seb qhov kev siv ib puag ncig thiab cov tsos ntawm cov hlau nplaum.

Ntxiv rau electroplating, txheej tiv thaiv nto ntawm sintered NdFeB hlau nplaum kuj muaj lub cev vapor deposition (PVD) txoj kev. Lub cev vapor deposition muab faib ua peb hom: evaporation plating, sputtering plating, thiab ion plating, uas tuaj yeem tsim Al, Zn, Cr thiab lwm yam txheej; Tshuaj vapor deposition (CVD) tuaj yeem tsim nitride thiab carbide coatings ntawm Ti, Cr, thiab lwm yam. Tsis tas li ntawd, sintered NdFeB hlau nplaum tseem tuaj yeem tau txais ntau yam kev tiv thaiv saum npoo los ntawm kev siv tshuaj lom neeg, electroless plating, kub dipping, thermal spraying thiab lwm yam.

 

Cov txheej txheem tshuaj xyuas thiab kev sim yog txhawm rau kuaj ntau yam ntsuas tau teev tseg los ntawm cov khoom xws li qhov loj thiab cov duab kam rau ua, lub xeev zoo li, txheej corrosion kuj, thiab cov khoom sib nqus ntawm cov hlau nplaum tiav.
