Cutting Tungsten

Tungsten is hard and sensitive to notches, and it is difficult to cut, requiring the use of cemented carbide tools. In order to prevent cutting cracks, the workpiece is often heated above the plasticity-brittle transition temperature for cutting, and the cutting operation procedures must be strictly controlled. The grinding of tungsten needs to be lightly ground with a specific type of grinding wheel, and it needs to be cooled, otherwise cracks will occur. Tungsten sheets with a thickness of 0.2 mm or more must be pre-heated before punching and shearing. Sheets with a thickness of more than a certain thickness cannot be cut and often need to be cut with a grinding wheel.
