We have had a very good experience in using high-porous vitrified CBN wheels for grinding Inconel. These wheels do not clog and grind a way cooler. Contact me for more detailes. gurinovich@abrazive.spb.ru
Our company has developed and tested a technology for inducing variable and controllable pores into vitrified CBN wheels. We will have editorial article on our new technology in the Industrial Diamond Review magazine. Test results and technical papers are available. Write to me at...
I believe there is no corelation between the grade of the bond and machanical scales like Rockwell and Knoop. The grade of the wheel reflects how strong the bond holds abrasive grains and not how hard a material it is. Two methods are used to test the grade of the vitrified bond wiht CBN...
What wheel have you been using? What is the spec? Is such short whel life caused by frequebt dressings? How many workpieces can you grind between two dressings?
I would suggest to try a extra-high-porous vitrified cbn wheel. There was an article on those wheels in the European Tool and Mould...
