【摘要】 从分析优质合金钢的薄壁件质量不合格的原因入手,结合难加工材料的高速切削机理,改进工艺流程,提出利用陶瓷刀具实现大型薄壁件高速切削的可行性,澄清了利用陶瓷刀具加工的几个误区,并对切削过程中的注意事项及切削参数的选择提出一些建议。实际使用表明在中型机床上利用陶瓷刀具可以实现大型薄壁件的高速切削,实现以车代磨,从而降低了生产成本,提高了生产效率,满足了产品的质量要求。更多还原

【Abstract】 Analyze the reasons of the sub-quality of advanced alloy steel thin-wall workpiece, considering the mechanism in high-speed cutting of the difficult-to-cut materials, improve the process and give the feasibility of high-speed cutting of large dimension thin-wall workpiece use ceramic tool, clarify some misunderstandings about it, and give some suggestions on the key points and the selection of parameters in cutting process. It is true in fact to use ceramic tools in cutting large dimension thin-wall workpiece in high speed on middle-sized machine tool,and substitute the grinding by cutting , it can reduce the cost , improve the productivity, and ensure the quality.更多还原
