Ball milling is a key step in the processing of tungsten carbide parts. It ensures a good distribution of the different powders and reduces the crystallite size in the nanometer range by "mechanical alloying". The study of the influence of the rotation speed and the milling medium on the sinterability of the WCCo composite is important.

Introduction Ball milling is generally known as a method to mix, blend, shape and reduce particle sizes. It can also be used as a mechanical synthesis method to produce materials that are milled to extremely fine powders. Several factors, like milling temperature, type of mill, milling speed etc. need to be considered when using ball milling as a synthesis method.

Tungsten can be cut with an abrasive cutoff wheel or ground through with the corner of a grinding wheel. Do not cut the electrodes with a wire cutter or break them by bending. This may result in unseen fractures at the cut ends, which can cause an erratic arc. Tungsten electrodes usually come with blunt ends that need to be sharpened before use.
