运用弹性力学和材料力学理论,通过理论分析和试验方法研究了HSK工具系统静态和动态的定位精度,给出了夹紧力和刀柄锥度的关系,并进一步指出合适的夹紧力是保证HSK工具系统在高速加工时轴向和径向定位精度的必要条件。分析结果表明:HSK工具系统能在高速情况下保证高精度,是由于实际的轴向夹紧力能保证刀柄的锥面和端面时刻与主轴保持接触。
Using the theory of elasticity and material mechanics, the static and dynamic positioning accuracy of the HSK tool system is studied by theoretical analysis and experimental methods. The relationship between the clamping force and the taper of the shank is given. It is further pointed out that the proper clamping force is to ensure the HSK Necessary conditions for precision axial and radial positioning of tool systems during high speed machining. The analysis results show that the HSK tool system can guarantee high precision under high speed conditions because the actual axial clamping force can ensure that the taper and face of the shank always keep contact with the main shaft.
