DIA/CBN Grinding Wheel Dressing and Sharpening Methods

Product Applications / By

For proper use of diamond/CBN grinding wheels, shaping and sharpening are necessary during initial installation or when the surface of the wheel is deformed. 1. Mild steel grinding and shaping – sharpening method 在砂輪的外周用油性筆進行標記，讓S45C等生材與之整體接觸（至油性筆記號消失），然後進行正常研磨，直至外周跳動消失。本方法在整形的同時也完成了修銳，因此可以此狀態進入正式作業。·請使用1180m/min的轉速，比通常轉速稍慢些。（參考：通常為1700～2000m/min左右）·如果轉速不能降低，請將切入量降至1mm左右嘗試。·進給速度采用30mm/min（每分鐘30毫米），近似於靜止的低速進給。 2.WA (White Corundum) or GC (Green Silicon Carbide) Oil Stone Grinding and Sharpening Method (For Surface Grinder)

Benefits of adding nanodiamond powder to lubricating oil

Product Applications / By

The addition of nanodiamond powder to lubricating oil significantly improves product quality and extends the lifespan of transportation tools, while saving materials. It reduces friction by 20%–40% and wear on friction surfaces by 30%–40%. In metal lubricants, nanodiamond powder can reduce wear by 1.7 to 2.0 times and shorten the break-in period by 1.5 to 2.4 times. Modified black and gray powder composites in plastics enhance thermal oxidation properties and crystallinity, though tensile and impact strength are affected by the filler content. The addition of nanodiamond gray powder to epoxy resin increases fracture strength by 2 to 2.5 times.
