Description
Technical Field
The utility model relates to a grinding machine technical field, a titanium oxide photocatalyst auxiliary metal bond superhard grinding wheel device of dressing on line that specifically says so.
Background
The super-hard abrasive grinding wheel is a main tool for grinding semiconductor materials, ceramics and super-hard alloys. The metal bond grinding wheel has the advantages of high strength, high hardness, good contour retentivity of the grinding wheel and the like, and is widely applied to ultra-precise grinding of hard and brittle materials which are difficult to process. The metal bond has the characteristics of large holding force on abrasive particles, good wear resistance and the like, so that the dressing of the metal bond superhard grinding wheel is difficult. As the grinding process progresses, the friction between the grinding wheel and the workpiece generates a large amount of heat, most of which stays on the surface of the grinding wheel and the workpiece. When the holding force of the grinding wheel binder to the abrasive particles is larger, the passivated abrasive particles are not easy to fall off, and the efficiency of the grinding wheel for processing the workpiece is lowered; the reduced grinding ability of the grinding wheel also results in a reduced surface quality of the machined workpiece. Dressing of the grinding wheel is therefore critical for the grinding process.
At present, the dressing method of the super-hard abrasive grinding wheel mainly adopts the traditional mechanical dressing method, such as diamond roller dressing, diamond pen dressing, elastic dressing, free abrasive grinding wheel dressing and the like. In order to further improve the accuracy and efficiency of grinding, the requirements for dressing accuracy of the grinding wheel have also begun to increase. Novel trimming methods such as electric spark trimming, electrolytic trimming, ultrasonic trimming, laser trimming and the like are also proposed. With electrolytic trimming techniques being the most typical. Generally, the thickness of the oxide film generated by electrolysis in the electrolytic dressing grinding process is from tens of micrometers to hundreds of micrometers, and a part of abrasive grains are separated from the grinding wheel before the workpiece is not machined (worn), so that the ineffective loss of the grinding wheel is increased. In addition, due to the nonlinearity of the electrolytic finishing process, the grinding force is unstable due to the damage of the insulating layer on the surface of the grinding wheel in the grinding process; when the electrolytic current is small, the formation and destruction processes of the oxide layer are long, and the grinding force is unstable. When the current is larger, the excessive dressing of the grinding wheel is caused, and the loss is overlarge. Meanwhile, a special electrolysis power supply and an electrode system are needed, the equipment is complex, and the use cost is high.
