Abstract: It is difficult to remove for burr, especially for micro-hole burr, so the vibration grinding process is put forward and adopted to remove burrs. The mechanism of vibration grinding deburring is analyzed, and the experiments of micro-hole deburring are done with the technology of vibration grinding. From the results of the experiments, the conclusion can be draw that this technology can remove the burrs effectively. The vibration grinding process has the features of simple process system, low cost, easy operating. The Vibration grinding process technology method can also be used to remove burrs of other machining process. It has more application value in practice.

Abstract: In modern manufacturing industry, there are a great deal of micro inclined holes, which is a difficult problem to machining. A novel micro inclined hole drilling method, step vibration drilling, is adopted. The experiments are carried that 45 degrees inclined hole is drilled into the 45 steel workpiece with Φ0.5mm carbide drill bit. The notable result was obtained with the method of step vibration drilling for drilling 45 degrees inclined holes on 45 steel, which break the restriction of drill jig. The new approach is put forward for micro inclined hole.
