Tungsten Carbide vs High-Speed Steel: ʻO ka hōʻike hope loa o nā lako Quill wili

Ma ke kahua o ka wili pololei ʻana, ʻo ke koho ʻana i nā mea quill e pili pono ana i ka maikaʻi a me ka maikaʻi o ka mīkini. ʻO Carbide a me ke kila kiʻekiʻe (HSS), ma ke ʻano he ʻelua mau mea nui, hōʻike kēlā me kēia i nā hiʻohiʻona hana kūʻokoʻa, e hana ana i kahi "hōʻike hope loa."

Hoʻohālikelike Hana Mea 

ʻO Tungsten carbide, i haku mua ʻia me ka tungsten carbide me ka cobalt e like me ka mea hoʻopili, loaʻa ka paʻakikī o HRA 88-93, kahi modulus elastic a hiki i 600 GPa, a me ka ikaika compressive ma mua o 4,000 MPa. I ka hoʻohālikelike ʻana, loaʻa i ka HSS ka paʻakikī o HRC 63-67, kahi modulus elastic ma kahi o 200 GPa, a me ka ikaika compressive ma kahi o 2,500 MPa. Hāʻawi kēia mau mea waiwai i ka carbide i mea maikaʻi i ka rigidity a me ka pale ʻana.

Hana Hoʻohana Hoʻomaʻamaʻa 

I nā noi me nā lākiō lōʻihi-a-diameter i ʻoi aku ma mua o 4: 1, hōʻike nā quills grinding carbide i nā pono hiki ʻole ke hoʻololi. ʻO kā lākou modulus elastic kiʻekiʻe e hōʻoia ʻia, ma lalo o nā kūlana haʻahaʻa like, ʻo ka deflection he hapakolu wale nō o ka HSS. He mea koʻikoʻi kēia no ka wili hohonu a me ka pololei o ka wili cylindrical kūloko. Hōʻike nā hoʻokolohua hoʻomaʻamaʻa inā ʻoi aku ka hohonu o ka mīkini ma mua o 150 mm, hiki i nā quills carbide ke mālama i nā hewa pōʻai i loko o 0.005 mm, ʻoiai ʻo HSS quills e hōʻike pinepine i nā deviations ma mua o 0.02 mm.

ʻIkepili waiwai 

ʻOiai ʻo ke kumukūʻai kūʻai mua o nā quills wili huila carbide he 3-5 mau manawa kiʻekiʻe ma mua o ko HSS huila quills, ʻo ko lākou ola lawelawe he 10-15 mau manawa lōʻihi. No ka laʻana, i loko o kahi laina hana ʻāpana kaʻa, hoʻololi i ka carbide quills i hoʻolōʻihi i nā manawa hoʻololi mea hana mai 8 mau hola a 120 mau hola a hoʻemi i ka helu kīnā o ka huahana mai 3% a 0.5%. Ke noʻonoʻo nei i ka manawa haʻahaʻa, nā koina hana, a me nā kumukūʻai ʻōpala, hāʻawi ʻo carbide i ʻoi aku ka maikaʻi o ka hoʻokele waiwai holoʻokoʻa.

Nā Manaʻo Manaʻo Hoʻohana 

ʻO ka HSS grinding quills e paʻa mau ana i nā pono ma kekahi mau wahi:  

1. Ma ka liʻiliʻi, kiʻekiʻe-variability hana, kahi haʻahaʻa kumu hoʻokomo koʻikoʻi.  

2. I ka hana ʻana i kekahi mau mea paʻakikī e pili ana i ka lihi kūkulu ʻia, hāʻawi ʻo HSS i nā waiwai anti-adhesion ʻoi aku ka maikaʻi.  

3. No ka paʻakikī paʻakikī wili palapala noi, HSS mea maʻalahi i ka mīkini i kūikawā ano.

Nā ʻano hoʻomohala e hiki mai ana  

Me ka puka ʻana mai o nā carbide nano-grained a me nā mea hana gradient, hoʻomau ka hana o ka carbide. Eia nō naʻe, mālama ʻo HSS i kona hoʻokūkū ma nā ʻano kikoʻī ma o ka ʻenehana pauka metallurgy a me nā kaʻina hana hoʻopili kiʻekiʻe. E noho pū ana nā mea ʻelua a hoʻomohala like no ka wā e hiki mai ana, akā e hoʻomau ka hoʻoikaika ʻana o ka carbide i ka mīkini kikoʻī kiʻekiʻe.

Pono e noʻonoʻo pono i nā pono mīkini, ka nui o ka hana ʻana, a me ka hoʻolālā kālā ke koho ʻana i ka mea pono wili. No ka hana ʻana i kēia wā, e ʻimi ana i ka pololei a me ka pono, ʻo ka carbide ka mea ʻoi aku ka maikaʻi o ka hoʻopukapuka.
