摘要: A high speed fluid jet nozzle made at least in part of a porous material and configured so that the is surrounded by reservoir containing lubricant fluid. As cutting passes through nozzle, from drawn lubricates surfaces exposed to jet. The invention not only resolves main difficulties prior art relating wear, it expands use applications cutters. By reducing wear possible increase reduce diameter even further than art, allowing much higher precision, deeper cutting, usage on difficult cut such as ceramics. thus provides reliable but yet very simple method for preventing wear.
