New abrasive waterjet machining systems are being developed that extend the operating range of abrasive waterjets. However, entry into the market of these new machining systems is dependent on factors that are not immediately obvious. The paper looks at the infrastructure needed to commercialise fine and micro abrasive waterjets. In particular the paper discusses how the quality control, packaging and distribution of abrasive becomes increasingly important as abrasive waterjet diameters are reduced. Reasons are given as to why abrasive waterjet equipment manufacturers need to develop proprietary abrasive delivery systems.
