It is recommended to perform rough machining before quenching because heat generation can affect quenching. In general, finishing machining does not generate enough heat to affect quenching.
This reduction in temperature considerably increases the life of the tool. It is also economical in energy consumption to machine aluminum; the power required to machine aluminum is two to five times lower than that required for machining steel alloys. All aluminum alloys are machinable. However, it is possible that the machining operation modifies the quenching of the workpiece.
Cutting is done using a high-pressure water jet or a water-based mixture and an abrasive substance. Abrasive water jet cutting cuts hard and thick materials. When the material is sensitive to high temperatures, this type of cutting is recommended. This process is used in the mining industry, Engineering Fabrication Perth and the aerospace industry.
