ʻO ka hoʻohana mua ʻana o ka High Speed ​​​​hoʻomākaukau e hoʻomau i ka hui ʻana i nā mea ʻoki like ʻole: drills, tap, processing cutters, device bits, hobbling (gear) cutters, saw sharp edges, planer, and jointer edges, switch bits, a pēlā aku. ., ʻoiai ʻo ka hoʻohana ʻana no nā kuʻi a me ke kīkē ʻana e hoʻonui ana ka bakeke.

Ua loaʻa i ka hoʻomākaukau wikiwiki kahi niche i nā mea hana lima maikaʻi kahi ko lākou lōʻihi lōʻihi me ka paʻakikī kiʻekiʻe i hui pū ʻia me ke kūʻē ʻana i kahi wahi kiʻekiʻe i ʻoki ʻia i kūpono no nā noi haʻahaʻa haʻahaʻa e pono ai kahi kikoʻoi aku, e like me nā lāʻau, etch, luna mokulele lima, a me nā lau kīhini. a me na pahi pelu mai Damaseko.

He mau amalgams ka hana wikiwiki e loaʻa ai ko lākou mau waiwai mai kekahi mau metala hoʻohuihui i hoʻopili ʻia i ke kila kalapona, e like me ka tungsten a me ka molybdenum, a i ʻole mai ka hui ʻana o nā mea ʻelua, i kekahi manawa me nā pūhui ʻokoʻa.Loaʻa iā lākou kahi kūlana i loko o ka ʻāpana hui nui Fe - C - X kahi e kuhikuhi ai ʻo X i ka chromium, tungsten, molybdenum, vanadium a i ʻole cobalt.Hiki ke hoʻohana ʻia ka ʻāpana X no ka hapa nui ma luna o 7 pākēneka, a me ka 0.60 pākēneka kalapona.

ʻO nā papa ʻano Tungsten (e laʻa me T1, T15) i ka ʻōnaehana helu hui (UNS) ua hāʻawi ʻia i nā helu ma ka hale T120xx, ʻoiai ʻo molybdenum (eg M2, M48) a me T113xx aia ma waena o nā ʻano alanui.Hōʻike nā helu ASTM i 7 mau ʻano tungsten a me 17 ʻano molybdenum.

ʻO ka hoʻonui ʻana ma kahi o 10% o ka tungsten a me ka molybdenum e hoʻonui i ka paʻakikī a me ka paʻa o ka High Speed ​​e hoʻomākaukau a mālama i kēlā mau waiwai i nā wela kiʻekiʻe i hana ʻia i ka wā e ʻoki ai i nā metala.

Pehea e hiki ai ke noho paakiki?

Ke noʻonoʻo ʻoe i kahi mea ʻoki HSS, e noʻonoʻo i ka wela.ʻO ka liʻiliʻi o ka mehana āu e hana ai (i loko o ka hāmeʻa), ʻoi aku ka lōʻihi o ka huki ʻana o kahi mea kani.I ka wā e wela ai ʻoe i ka HSS, lawe ʻoe iā ia i kahi mahana kikoʻī (i kēia manawa a kapa ʻia ʻo ka wela kiʻekiʻe) no ka manawa i koho mua ʻia.Hāʻawi kēia i ka HSS i kona paʻakikī paʻa, akā naʻe, nāwaliwali loa.A laila lawe ʻo ia i kahi mahana e "hoʻohaʻahaʻa a huki paha" iā ia.Hana ʻia kēia ma mua o hoʻokahi manawa.Lawe kēia i ka paʻakikī i kahi āu e pono ai a hāʻawi i ka HSS sturdiness (ʻo ka paʻakikī a me ka ikaika e mālama ʻia e ka composite i loko o ka mea).ʻAʻole pono e ʻoi aku ka mahana o ka Tempering i ka hoʻohana ʻana a i ʻole ka hoʻonani ʻana i ka hāmeʻa a i ʻole e paʻakikī (hoʻomaha).E ʻokoʻa kēia mai nā kikoʻī ʻelua (Rc) i kahi ʻaoʻao piha.He wehewehe koʻikoʻi kēia o ka HSS maikaʻi loa.
