Using fixed abrasive ultra-precision grinding technology is currently a hot research

Single crystal sapphire has a series of excellent performance, Mohs hardness up to 9, in the military and civilian fields with a wide range of uses. Because of its hardness, the traditional processing methods planarization (grinding + polishing) exist processing efficiency is low, difficult to automate, environmental pollution and other shortcomings, therefore, domestic and foreign experts and scholars has been committed to how to achieve efficient monocrystalline sapphire substrate, no damage the surface of the ultra-precision machining  Diamond blade . Among them, the use of fixed abrasive ultra-precision grinding technology is currently a hot research and has achieved remarkable results, but the traditional diamond grinding wheel inevitably will produce single-crystal sapphire  synthetic diamond  surface damage, you need to follow the chemical mechanical polishing to remove the damaged layer, but reduces the processing efficiency of the substrate. For these problems, in order to efficiently process non-destructive  grinding wheel  sapphire substrate made ​​of soft abrasive grinding wheel using a single crystal sapphire processing method using abrasive wheel, additives and the sapphire single crystal solid-phase chemical reactions between and soft abrasives mechanical friction to achieve single-crystal sapphire substrate, ultra-smooth, low damage grinding.
