Manufacturing of graded grinding wheels for flute grinding

Abstract. In this paper, two different methods for manufacturing of graded grinding wheels for two different metal bonds are presented. One method is based on the use of a mask and manual moulding and the other on a height-adjustable holder for moulding. For this purpose, a brittle and a ductile bronze bond are compared. The graded grinding wheels are fabricated through sintering with Field Assisted Sintering Technology (FAST). An analysis of the grain distribution is used to demonstrate the reproducibility of the manufacturing methodology. For analysis, light microscope images of cross-sections of the abrasive layers are taken. The grain distribution is determined using image processing software and a greyscale method. Finally, the advantages of each method are compared. As a result, both manufacturing methods are evaluated in terms of precision, feasibility and efficiency. From this, a recommendation on the implementation and further development of the methods is derived. This method enables the manufacturing of graded grinding wheels for an effective reduction of wear differences for grinding cemented carbide end mill cutters.
