- 摘要:
- 为了改善PVD (Physical Vapor Deposition)涂层阶梯杆的表面质量，实验中采用磁粒研磨的方法对阶梯杆进行磨削加工，并对实验参数进行优化，得出最佳磨削加工参数。结果表明，优化后的实验参数为：磁性磨粒的粒径大小为250 μm，车床主轴转速为750 r/min，加工间隙为3 mm。用优化后的参数对阶梯杆进行磨削加工40 min，阶梯杆表面粗糙度从原始的Ra 1.35 μm降低到Ra 0.26 μm，阶梯杆表面光洁度有明显提高。
- Abstract:
- In order to improve the surface quality of the step rod coated with PVD (Physical Vapor Deposition), the magnetic abrasive finishing was used to grind the step rod in the experiment, and the experimental parameters were optimized to obtain the optimal grinding parameters. The results showed that the optimized experimental parameters were as follows: the particle size of magnetic abrasive particles was 250 ?m, the spindle speed of lathe was 750 r/min, and the machining gap was 3 mm. After the optimized parameters were used to grind the step rod for 40 min, the surface roughness of the step rod was reduced from Ra 1.35 ?m to Ra 0.26 ?m, and the surface finish of the stepped rod was obviously improved.
