Aluminum

More sensitive aluminum alloys should be dried and stored after machining to prevent discoloration issues.

*Tool breakage can result from insufficient lubrication properties of the cutting fluid in use. Consider switching to a cutting fluid with better lubrication properties.

*Check if the machine's nozzle is properly aligned with the cutting tool's machining position to ensure even lubrication.

* Evaluating machining conditions, such as machine flushing pressure, tool durability, cutting fluid lubrication, and most importantly, machining parameters, is essential to accurately identify the causes of tool breakage.
