摘要

摘要: 为了解决高温合金钻削温度高、刀具磨损快的问题,采用微量润滑的振动钻削加工方法,从换热机制角度对振动钻削的降温机理进行分析,并进行振动钻削和普通钻削对比实验.结果表明:微量润滑普通钻削的最高测量温度达到了110℃且温度随钻削深度、钻孔个数的增加而升高,而振动钻削的测量温度为55℃左右且随削深度、钻孔个数的增加增长缓慢;普通钻削刀具磨损量达到0.5 mm且随钻孔个数的增加磨损加剧,振动钻削刀具磨损量只有0.22 mm且磨损量增加缓慢.

Abstract: Processing method of minimum quantity lubrication (MQL) vibration drilling was used to solve difficulty of high cutting temperature and rapid tool wear in drilling of superalloys. Cooling mechanism in vibration drilling was analyzed from the point of heat transfer mechanism and comparative experiments between traditional drilling and vibration drilling were carried out. The results show that the cutting temperature in MQL traditional drilling reaches 110℃ and increases with the drilling depth and the number of holes, while the cutting temperature in MQL vibration drilling is only about 55℃ and changes slowly with the drilling depth and the number of holes; Tool wear in MQL traditional drilling reaches to 0.5 mm and significantly increases with the number of holes, while tool wear in MQL vibration drilling is only 0.22 mm and slowly increases with the number of holes.
