主轴是机床的重要部件之一，主轴的热性能和动态性能直接影响机床的加工精度和生产效率。本研究探讨碳纤维强化塑料（CFRP）应用于主轴对机床主轴性能的影响。CFRP和钢主轴具有相同的几何形状，开发公平的比较。开发的轴和主轴单元的热性能和动态性能进行了评估和比较。实验和仿真结果表明，CFRP主轴提高了主轴的轴向热位移和动刚度。轴向热位移减小到钢主轴的1/3。依从性也降至1/2。为了保证CFRP主轴的热稳定性，轴承周围的热位移分布设计是一个重要的问题。
Spindle is one of the most important component of machine tools because spindle’s performance including thermal property and dynamic property greatly influences the accuracy and productivity in machining process. This study investigates the effect of the application of carbon fiber reinforced plastic (CFRP) to the spindle shaft on the performance of machine tool spindles. CFRP and steel spindle shafts with the same geometry were developed for fair comparison. Thermal and dynamic properties of the developed shaft and spindle unit were evaluated and compared. The experimental and simulation results showed that the CFRP spindle shaft improved the axial thermal displacement and dynamic stiffness. The axial thermal displacement was decreased to 1/3 of that of the steel spindle. The compliance was also decreased to 1/2. The design of the thermal displacement distribution around the bearing should be an important issue in the CFRP spindle for the thermal stability of the dynamic property.
