When working with aluminum die castings and mold blanks, it is unavoidable that the tools used in the CNC processing process will become worn over time. It is only possible to discard tools that have become excessively worn, thereby extending the tool's service life while simultaneously reducing the cost of aluminum alloy die casting in a covert manner. The coating technology will be implemented for the current cutting tools in order to increase the service life of the cutting tools while also s...
