Grinding is a material removal process making use of geometrically nondefined tool edges, or abrasive particles, which is bonded together in the form of a grinding wheel to cut, or machine, a material into shape. The materials used as the abrasive is most commonly aluminium oxide or silicon carbide. These abrasives are normally bonded with a vitrified or resinoid bonding to form the grinding wheel. Grinding wheel applications typically range from wood and soft metal grinding to hard carbide steel and ceramic grinding. There is thus a gap in the variety of available grinding wheels for a multipurpose grinding wheel. This paper will explore the application of tungsten carbide (WC-12wt%Co) as an alternative abrasive material for a grinding wheel and will be bonded with inexpensive resin. Tungsten carbide falls in the cemented carbide family of hard materials, having a high hardness-to-toughness ratio. This is advantageous for the machining of titanium alloys and is the workpiece material. The paper will describe the process of custom manufacturing of the WC-12wt%Co grinding wheels for experimental purposes.
