超声珩磨钢质薄壁缸套的试验设计研究

Experiment and Design of Steel Thin Wall Cylinder Liner of Ultrasonic Honing and Its Research

采用纵向振动立式超声珩磨装置,分别在MB4215Z型半自动珩磨机和M4215型珩磨机上,对钢制薄壁缸套基体进行三因素、四水平正交试验,研究了超声珩磨油石的特性,包括超硬磨料、粒度、结合剂等对表面粗糙度、尺寸精度、圆度和珩磨效率等的影响及影响程度。结果表明,超声珩磨可以有效地解决钢制薄壁缸套的珩磨加工难题,为珩磨加工软钢提供了理论依据,对实际生产具有一定的指导作用。

This paper uses longitudinal vertical ultrasonic vibration honing device, respectively in MB42ISZ type semi-automatic honing machine and M4215 type honing machine to do three factors and four levels orthogonal test for steel thin wall cylinder liner and studies the characteristics of the ultrasonic honing oilstone, including super hard abrasive, grain size and binder on the surface roughness, dimensional accuracy, roundness, and the influence on honing efficiency. Results show that ultrasonic honing can be used to effectively solve the steel thin wall cylinder honing processing problems and a theoretical basis is provided for honing processing mild steel. This gives a certain guiding role to the actual production.
