Development of Melamine-Bonded Diamond Wheels with High Porosity for Smooth and Mirror Finishing of Die Materials

摘要: Abstract Diamond wheels with fine grains and pore structures were newly developed for smoothing mirror-polishing of die materials. bonded firmly by melamine resin to prevent the decrease machining efficiency due grain sinking within bond Also, highly foamed increase flexibility wheel, induce active self-dressing increasing contact pressure between wheel work surfaces. It was confirmed that equal a conventional PVA-bonded could be achieved porosity over 75 %. it swarf loading prevented completely excellent grinding performance assisted derived
