摘要
针对钛合金磨削加工中容易造成工件烧伤及加工质量不易保证的难题,提出了一种新的高效冷却技术———低温气动喷雾射流冲击冷却技术,并依据此思想开发出一套低温气动喷雾射流冲击冷却系统,将其应用于钛合金的磨削加工中。试验结果表明,相对于低温冷风和常规浇注冷却,低温气动喷雾射流冲击冷却具有明显的冷却优势,它可将磨削温度和工件表面粗糙度控制在较低的水平。
To solve the problems of workpiece--burn in grinding of titanium alloys, a new high efficiency cooling technology--cryogenic pneumatic mist jet impinging cooling technology （CPMJI） was offered. It can greatly enhance heat transfer in the grinding zone. The effect of CPMJI on grinding performance of Ti-6A1-4V was analyzed to compare with cold air and conventional flood cooling method. The experimental results indicate that good effects experienced with CPMJI are achieved, especially in higher depth of cut.
