R4.7 Hemisphere diamond grinding head spiral groove design, glass fiber drilling, reaming and trimming

Diamond tools

Glass fiber is a high-performance inorganic non-metallic material with a wide variety of advantages such as good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. However, its disadvantages are brittleness and poor wear resistance. Hard alloy drill bits or diamond grinding heads can be used to drill holes on glass fibers. Hard alloy drill bits break materials by the impact load generated by drilling pressure and self rotation, while diamond sand is a type of silicon dioxide crystal, which is an industrial polishing agent. The finished product has round inner holes and smooth and delicate inner walls. The glass fiber produced by using a round head diamond sand grinding head is of high quality and accurate size, supporting customization.
