Abstract: As a kind of precise surface finishing technology, magnetic abrasive finishing has wide application, low cost, high efficiency, good effects, and other advantages. Magnetic induction intensity is one main parameter affecting finishing effect and efficiency of magnetic abrasive finishing. Saturation magnetic induction intensity for different magnetic abrasives is defined through test device designed by ourselves. Affecting rules of saturation magnetic induction intensity is discussed by experiments, which provide basis for parameters selection and practical application of magnetic abrasive finishing.

Abstract: At present, crankshafts are finished mostly by abrasive cloth and manual steel brush, which is not ideal on finishing quality, efficiency, cost and cleanness degree. So a new process, horizontal spindle barrel finishing, is developed. Based on its finishing mechanism, factors and effect affecting finishing uniformity are analyzed by theory and experiment, finishing effect is defined, which provides basis for parameters selection of crankshafts barrel finishing.

Abstract: As a kind of precise surface finishing technology, magnetic abrasive finishing has wide application, low cost, high efficiency, good effects, and other advantages. Finishing clearance is one main parameter affecting finishing effect and efficiency of magnetic abrasive finishing. Affecting rules of finishing clearance and filling volume are discussed by experiments, which provide basis for parameters selection and practical application of magnetic abrasive finishing.

Abstract: At present, crankshafts are finished mostly by abrasive cloth and manual steel brush, which is not ideal on finishing quality, efficiency, cost and cleanness degree. So a new process, horizontal spindle barrel finishing, is developed. By theoretic research and simulation, main factors for finishing effect and uniformity are analyzed. The research indicates that this process is very effective for crankshafts, and has also positive influence on efficiency and auto product line.

Abstract: The magnetic abrasive finishing process of thin sleeve of Al alloy with different diameter is studied based on self-adaptive characteristics. Some technical innovations are done such as fixing smooth magnetic mandrel or slot magnetic mandrel and so on in the workpiece interior for improving the structure style of the working space and characteristic of magnetic field. Experiments on thin sleeve of Al alloy are done and their finishing effects are contrasted. Research results indicate that fixing slot magnetic spindle in the workpiece interior can increase efficiency and improve quality for large thin non-magnetic sleeve.
