重庆钢铁厂生产的501高速钢(W_6M_5Cr_4V_2Al),近年来在我厂生产的刃具中应用越来越广泛。这种高速钢比普通高速钢(W_(18)Cr_4V)具有更好的切削性能和较高的耐用度,而价格与普通高速钢相近。去年12月我厂为美囪试制的立铣刀,由501钢整体制造。经美方试验:用美方生产的立铣刀(W_(18)Cr_4V)加工某产品需耗费10把刀8个小时,而用我厂生产的立铣刀加工同一产品,只耗费2把刀3个小时,工效与刀具寿命都大大提高。但由于这种材料经 Chongqing Steel Plant production of 501 high-speed steel (W_6M_5Cr_4V_2Al), in recent years in our factory production of cutting tools used in more and more extensive. The high-speed steel has better cutting performance and higher durability than ordinary high-speed steel (W_ (18) Cr_4V), and the price is similar to ordinary high-speed steel. Last year in December I plant for the trial of the United States Endmill cutter, the overall manufacture of 501 steel. The U.S. test shows that using a U.S.-made end mill (W_ (18) Cr_4V) would cost 10 knives for 8 hours and using the same mill produced by our mill would cost 2 knives and 3 knives Hours, work efficiency and tool life are greatly increased. But because of this material
