The experiments of high speed milling of titanium alloy were conducted under different cooling and lubricating modes , i . e . dry milling , flood coolant , oil mist with nitrogen gas , cryogenic nitrogen gas jet , and cryogenic nitrogen gas jet with minimal quantities of lubricant 在干铣削、浇注切削液、常温氮气油雾、低温氮气射流和低温氮气射流结合微量润滑等冷却润滑条件下进行了钛合金的高速铣削对比试验。
Continue to invest usd $ 450 , 000 to buy mazak ( 12000r . p . m ) cnc high speed milling machine from japan and a agie wire cutting machine from switerland , electric discharge machine , and drilling electric machine . the initial model is processed and manufactured in the single factory uniformly 高速铣床及瑞士制造agie线切割,细孔放电机,亚特精密放电机,初步建构出模具零件在单一工厂内一贯化加工完成之蓝图。
It has been pointed out that for the application of cryogenic nitrogen gas jet in high speed milling of titanium alloy , unless the chipping and fracture caused by thermal cracks take place , the reduced temperature of cryogenic nitrogen gas will prolong the tool life 指出在低温氮气射流条件下高速铣削钛合金时,只要热裂纹的形成与扩展未引起刀具的崩刃及刀面的剥落,进一步降低低温氮气的温度将提高刀具的使用寿命。
Abstract : the significance of the high speed cutting technology is described . the application and advantagies in the electrode manufacture , cavity machining of quench - hardening material and prototyping are introduced . the requirement to the high speed milling machine is pointed out 文摘:叙述了高速切削技术的意义,并介绍了它在电极制造、淬硬材料型腔的直接加工及样件的快速成型中的应用及优点,并简要说明对高速铣床的要求。
As a result , the spiral cutting contact points " tracks are successfully created on the surface of the blade for 4 or 5 axis high speed milling , it is shown that the spiral cutting contact points " tracks generated by both methods can satisfy the calculation of the cutter location with perfect simulation results 最终在叶片表面构造了适合四、五坐标联动机床高速加工的螺旋切触点轨迹。经实例验证,本文所规划的螺旋加工切触点轨迹能够满足刀位点的计算,并取得了良好的仿真效果。
