Ubuchwepheshe obulula bokucutshungulwa kwama-bearings wukuncibilikisa-ukusakaza-i-annealing-rough machining-quenching, ukushisa-ukuqeda. Ukuqina kocwecwe lokusebenza ngemva kokucisha kanye nokushisa kuvamise ukuba ngaphezu kwe-HRC45. Ezingxenyeni zensimbi ezinokuqina okuphezulu, amathuluzi okusika endabuko (amathuluzi okusika i-carbide namathuluzi okusika i-ceramic) awasakwazi ukuhlangabezana nezidingo zokucubungula. Ukusebenza kwamathuluzi e-carbide enosimende ngeke kuchazwe ngokuningiliziwe lapha. Njengamanje, izinto ezisetshenziswayo ezilungele ukucubungula izingxenye zensimbi ezinobulukhuni be-carbide zifaka amathuluzi e-ceramic namathuluzi we-cubic boron nitride. Amathuluzi e-Ceramic aziwa kahle ukuthi ane-brittle futhi awakwazi ukuphendulwa ngamamajini amakhulu. Ukusika izikhawu akuvunyelwe. Uma i-deformation ye-workpiece ngemuva kokwelashwa kokushisa incane, ubuso bubushelelezi, futhi i-margin incane, kufanelekile ukukhetha amathuluzi e-ceramic.

Ngokusho kwezingxenye zokusebenza ezihlukene, ubulukhuni, kanye nemvume, khetha amamaki ethuluzi le-carbide afanelekile kanye nemingcele yokusika. Uhlelo lumi kanje:

(1) Umzila womjaho we-carbide ophendulwe kahle, ubuso bokuphela, ubulukhuni HRC47-55, isibonelelo

Umphumela wokucubungula: Impilo yethuluzi le-carbide enosimende iphindwe izikhathi ezingu-7 kuneyamathuluzi e-ceramic, futhi ukuhwaqeka kwendawo kulawulwa phakathi kuka-Ra0.6-1.0.

(2) Iqedile ukuphendukela kusiyingi sangaphandle esithwele i-carbide, ubuso bokuphela, ubulukhuni HRC47-55, ubulukhuni besiteshi HRC55-62; imajini ≥ 2mm

Umthelela wokucubungula: Ithuluzi le-Carbide linempilo ende yethuluzi futhi lingangena esikhundleni sokugaya okumahhadlahhadla, futhi ubuhwaqane obungaphezulu bufinyelela ku-Ra0.4.

(3) Indilinga yangaphandle ye-metallurgical carbide ejike kahle kanye nembobo engaphakathi, ubulukhuni HRC62:

Umthelela wokucubungula: Uma uqhathaniswa namathuluzi okusika angaphandle, unokuphila kwesevisi ende futhi ukugoqa kwendawo kungaphakathi kwe-Ra0.8.
