M7 Kiekie Kiekie Mea Paahana Steel Poe Bar

Ma ke ʻano he ʻāpana o nā kila mea hana, loaʻa nā ʻāpana HSS i nā hiʻohiʻona kūpono e hana ʻia i nā mea hana. ʻO ka manawa pinepine, ʻo ka HSS Steel Rod he ʻāpana o nā ʻāpana drill a i ʻole nā ​​​​lau ʻike mana. ʻO ka hoʻomohala ʻana i nā kila mea hana e hoʻomaikaʻi ai i nā hemahema o ke kila kalapona. Hiki ke hoʻohana ʻia kēia mau ʻāpana i nā mahana kiʻekiʻe e like me ke kila kalapona, me ka nalowale ʻole o ko lākou mau ʻano paʻakikī. ʻO ia ke kumu e hiki ai ke hoʻohana ʻia ka High Speed ​​Steel Round Bar e ʻoki ʻoi aku ka wikiwiki i ka hoʻohālikelike ʻana i nā kila kalapona maʻamau, e loaʻa ana ka inoa - High speed steel. ʻO ka mea maʻamau, ʻoi aku ka ʻoi aku o ka paʻakikī o kekahi alloy High Speed ​​Steel Square Bar ma luna o 60 Rockwell. ʻO ka hoʻohui kemika o kekahi o kēia mau alloys e loaʻa i nā mea e like me tungsten a me Vanadium. Ua kūpono kēia mau mea ʻelua i nā noi kahi mea koʻikoʻi ke kūʻē i ka ʻaʻahu a me ka abrasion. ʻO kēia ke kumu no ka hoʻonui ʻana o ka tungsten a me ka vanadium i ka paʻakikī o ka M2 High Speed ​​​​Steel Rod, no laila e pale ai i nā mana o waho e hana i nā abrasions aʻo ka mālama ʻana i ka alloy mai ka luhi mua.
