BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a subtle vortex polishing apparatus, particularly to a subtle vortex polishing apparatus in which the fluid abrasive in the receiving unit forms the eddy friction for polishing the workpiece and the deburring, polishing, chamfering for the workpiece can be finished in one time. Thereby, the grinding effect of the inner and outer surfaces of the workpiece enhances, and this invention can be thus used in processing small, bored, cracked, cambered complex surfaces, achieving the effects of easy operation, single-sided or multi-surface processing at the same time, increase in the processing rate, significant reduce in labor intensity, reduced processing costs and improved productivity.
2. Description of Related Art
Omori et al., Japan Patent in 2002, disclosed non-metal bonded grinders, an electrolytic dressing grinding method and apparatus therefore, which use the abrasive and carbon-containing non-metal composite having the abrasive for electrolysis, reaching good yield and good processing effect.
Even though the grinders and electrolytic dressing grinding are used to grind the workpiece to be polished in the above processing method to improve the surface roughness, difficult shapes such as small, bored, cracked, arc, complex surfaces etc. on the workpiece to polished still needs more powerful technology to remove with enhanced feed efficiency.
VKGorana et al in 2004, International Journal of Machine Tool & Technology, Vol. 44, pp. 201-211, discussed the influence of the extrusion pressure, abrasive concentration, particle size for abrasive flow machining on the material removal amount, surface roughness, cutting force and actuating abrasive grain density. These processing parameters includes: the abrasive particle size, abrasive type and concentration of the mixing ratio, processing time, and workpiece material. Such an approach utilizes the pressure by the abrasive generates the reciprocation directly on the workpiece, removing the material from the workpiece and improving the surface roughness. However, for precision transmission mechanism, such as small, bored, split, cambered, complex surfaces, the material removal capacity is limited and the feed efficiency and surface roughness still need to be improved.
Another VKJain et al, International Journal of Machine Tool & Manufacture, Vol. 44, pp. 1019-1029, 2004, disclosed a combination of abrasive in electromagnetic rheological fine polishing for surface processing, and discussed the influence of different abrasive configuration on surface roughness and material removal. In subsequent development, rotating magnetic poles are used to drive magnetic abrasive to rotate to explore the influence of shape and rotating speed of the magnetic poles on surface roughness and material removal. In processing the surfaces with complex shapes such as helical surface, the improvement in material removal and surface accuracy is limited,
For this reason, the inventors has studied and proceeded in-depth discussion, and actively seek approaches for many years engaged in the research and experiences of related industries and manufacturing. After long-term research and efforts in development, the inventors has finally the successfully developed this invention ‘a subtle vortex polishing apparatus’ which overcomes the shortages in the prior art.
