At present, crankshafts are finished mostly by abrasive cloth and manual steel brush, which is not ideal on finishing quality, efficiency and cost, especially cleanness degree does not meet design and use request. So horizontal spindle barrel finishing has been developed. Based on its finishing theory, process characteristics are key factors affecting the finishing effect, especially finishing uniformity. Process characteristics of motion parameters, finishing depth, finishing time, etc. are analyzed, and reasonable parameters are defined. Finally, finishing effects are verified. It provides basis for industry application of this process.

As a kind of precise surface finishing technology, magnetic abrasive finishing has wide application, low cost, high efficiency, good effects, and other advantages. Magnetic abrasive performance is one main factor affecting finishing effect and efficiency of magnetic abrasive finishing. By experiments, process and parameters of hot pressing sintering preparation are defined, its micro-structure and finishing performance are researched. The results show that magnetic abrasives prepared by hot pressing sintering process has good finishing performance, long service life, adaptability, and can effectively improve surface quality.
