Cutting temperature and tool wear in minimum quantity lubrication vibration drilling of superalloys

  • 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.
