Технология распиливания твердых и сверхтвердых кристаллов при сообщении заготовке вынужденных колебаний

Abstract

The traditional method of mechanical sawing has certain drawbacks connected with low productivity of the process and insufficiently high quality of table surfaces of sawn workpieces. In research the industrial sawing unit applied to separate diamond is used. This unit is equipped with special vibrotransmission which transfers periodic circular two- dimensional movement to a workpiece. It is experimentally proved that it is possible to significantly raise intensity of

272 sawing of the workpiece and to provide significant decrease in roughness values of the parameter Ra of the processed surface in comparison with the values received in traditional operating conditions by transferring periodic two- dimensional circular movement to the workpiece with a trajectory similar to an ellipse.
