CBN磨料特性对树脂砂轮磨削性能的影响
Influence of different CBN grains on grinding performance of resin bonded CBN grinding wheel
摘要
Abstract
The compressive fracture strength, toughness index (TI) and thermal toughness index (TTI) data of 6 kinds of different CBN abrasive grains are studied, and these grains are made into resin bonded CBN grinding wheel, respectively.The grinding ratios of different CBN abrasives on different materials, such as cast iron, high speed steel, stainless steel and nitride stainless steel are researched.Results show that at the same condition of wheel binders and production process, grinding ratios of different CBN abrasive grains show the dramatic differences.Grinding ratios of resin bonded CBN wheels for grinding the cast iron and high speed steel are relatively higher, while its grinding ratios for grinding the stainless steel and nitride stainless steel are lower.It is also found that grinding performances of CBN-B1500 and CBN850 abrasive are relatively better for four materials.In conclusion, because of CBN grains in the grinding wheel are fixed by the mechanical insertion force of the resin binder, and so CBN grains with rough surface and moderate compressive fracture strength are better choice.关键词
