由于钛合金具有强度高、耐腐蚀性能好、热强性能好的特点,因而它在航天、航空工业中得到日益广泛的使用。但又由于钛合金弹性模量小、导热系数低、化学亲合力强,给切削加工带来了困难。为此,我们对钛合金的钻削进行了切削试验,选择合适的刀具材料,几何参数与最佳切削用量。TC—9钛合金钻削试验在立式钻床Z535上进行,采用组合夹具;电解润滑冷却液,钻头采用φ5、φ8、φ12、φ16四种规格;W_8Cr_4V、W_6Mo_5Cr_4—V_2Al(M_2Al)、W_2Mo_9Cr_4VCo_8(M_(42))等三种材料;分别以三种速度、三种走
Due to its high strength, good corrosion resistance and good heat resistance, titanium alloy is widely used in aerospace and aviation industries. However, due to the small elastic modulus of titanium alloy, low thermal conductivity, chemical affinity, to the cutting process has brought difficulties. To this end, we conducted a cutting test of titanium alloy drilling, select the appropriate tool material, geometric parameters and the best cutting dosage. TC-9 titanium alloy drilling test is carried out on a vertical drilling machine Z535 with a combination of fixtures; Electrolytic lubrication of the coolant, the drill with φ5, φ8, φ12, φ16 four specifications; W_8Cr_4V, W_6Mo_5Cr_4-V_2Al (M_2A1), W_2Mo_9Cr_4VCo_8 (M_ (42)) and other three materials; respectively, three kinds of speed, three kinds go
