高速空气涡轮机主轴中使用的微型切削工具的效率取决于转子的旋转速度。转子表面上的高压变化导致转子减速，这严重限制了高速转子（HSS）的可靠性和耐用性，以支持微加工发展领域的新发展。提出了多种主轴设计，并使用CFX软件对每种设计进行了数值模拟。结果表明，转子，进口和出口的几何形状的变化影响转子上的压力分布显着。根据CFX结果获得的转子表面上的最低压力变化确定最佳设计。以非常高的速度旋转转子为机械微加工的发展提供了一个新的方向。
The efficiency of microcutting tools that are used in high-speed air turbine spindles depends on the rotational speed of the rotor. A high-pressure variation on the surface of the rotor causes the rotor to retard and this severely limits the reliability and durability of High-Speed Spindles (HSSs) to support new developments in the developing area of micromachining. A variety of spindle designs were proposed and numerical simulations were carried out for each design using CFX software. The results revealed that changes in the rotor, inlet and outlet geometries affect the pressure distribution on the rotor significantly. The optimum design was identified based on the lowest pressure variation on the rotor surface obtained from the CFX results. Spinning the rotor at very high speeds provides a new direction in the development of mechanical micromachining.
