000 Summary 10 CBN and diamond are growing as abrasives of choice for all forms of manufacturing. The flexibility of vitrified bonds is the catalyst behind this rapid market growth and acceptance. Newgrinding process Q' the grinding wheel is deflected away from the workpiece. The deflection makes it difficult to control workpiece size to a high order of accuracy since there is a difference between the programmed infeed position and the actual infeed position. In order to achieve the correct workpiece size and roundness

If the wheel was deflected during grinding it will relax back to parallel during spark-out and grind those places that were tending to taper. So increasing the spark-out period a second or two is often a fast and easy solution for correcting this sort of taper problem. Solution # 4: Retract and Regrind:Jan 01
