You are most probably aware of the high prices for PCD tools. PCD instruments are only manufactured for specific aluminium machining, whereas different devices are incompatible. It is feasible to utilize PCD devices in high-rate production, meaning PCD instruments can handle incredibly high speeds. Selecting PCD tools for finishing close-tolerance elements will offer the most satisfactory results, due to the immunity of PCD tools to aluminium welding, which is a very critical problem where aluminium chips weld to the cutting boundary. The impaired grade of the finished surface will bring another situation where the surface will not able to hold hard tolerances and these all are outcomes of chip welding issues.
