易变形结构铝制滑槽精加工技术

Easy Deformation Structure of Aluminum Alloy Spout Stool Finishing Technology

目前,国内类似结构的导轨、滑槽加工技术虽然较为成熟,但铝质燕尾槽加工无同行业经验借鉴。针对易变形结构铝制滑槽精加工过程中机械加工变形量大、燕尾槽加工效率低和废品率高的特点,将易变形铝质燕尾槽结构加工由插车插制结合人工刮研的方法,改为利用加工中心数控铣燕尾槽及利用慢走丝线切割燕尾槽。通过调整工艺参数,优化刀具设计,设计装卡方式,改进滑槽加工方法,满足了其几何公差及表面粗糙度要求,达到了控制机械加工变形,提高产品生产效率和合格率的目的。

The similarly domestic processing technology of guide chute is more mature, but the processing dovetail groove aluminium currently does not have the same industry experience, for the easy deformation structure aluminum chute finishing process of CMC with large deformation, the low dovetail groove processing efficiency and the characteristics of high reject rate, it will easily let the deformed aluminum structure of dovetail groove processing by inserting system accept ante instead of using CNC milling machining center dovetail groove and the dovetail groove binding wire cutting method of artificial scraping. By adjusting the process parameters, the optimization of cutting tool design and the design of clamping way, the improvement of chute processing method, it can control the machine with deformation to meet the various requirements of form and position tolerance, and improve the production efficiency and the qualification rate of products the purpose of roughness.
