Aluminum Milling

Trace-A-Matic specializes in CNC milling of aluminum parts and assemblies using state-of-the-art CNC mills, 5-axis machining centers, and high-speed cutting tools. Years of experience provide expert knowledge of cutting a wide range of aluminum alloys, their characteristics, and how the aluminum material group reacts when machined. Tool selection, cutting pass depths, mill/lathe feed and speed, chip control, and high-pressure coolant are critical in controlling heat generation, which can cause part movement and tool deflection during the machining process. This level of skill ensures world-class precision machining that meets or exceeds the most demanding tolerances. The innovative Trace-A-Matic team is always available to review your machining parts and guide you during the design process. Our goal is 100% customer satisfaction, providing AS 9100/ISO 9001:2015 certified quality machining resulting in timely turnaround and on-time delivery.

Aluminum Milling

Al Melting Point

  • High strength to weight ratio
  • Excellent machinability
  • Excellent corrosion resistance
  • 2000 series contains copper agent and is heat treatable
  • 5000 series has magnesium agent and is non-heat treatable
  • 6000 series contains silicon and magnesium agent and is heat treatable - aluminum 6061 being common
  • 7000 series contains zinc agent and is heat treatable - aluminum 7075 and 7050 being common

Trace-A-Matic is highly skilled in using cutting-edge milling machines to perform high-speed machining of aluminum milled parts and assemblies. The proper machining tools, cutting speeds and feed rates, radial engagement, chip removal rates, depth of cut, and cutting force are essential to reduce heat, tool deflection, and prolong tool life. Resulting in high-quality, precision machined parts to the desired surface finish. Aluminum CNC milling is an excellent choice for rapid prototyping.

In metalworking, the selection of tools for aluminum play a pivotal role in achieving optimal results, particularly in aluminum applications. Flute end mills, designed with various configurations such as corner radius and higher helix angles, are indispensable for machining aluminum due to their ability to enhance chip evacuation and minimize tool deflection. The choice of tool material becomes crucial when dealing with aluminum, cast, and wrought varieties. Zirconium nitrides, known for their exceptional wear resistance, are often preferred for their longevity and efficiency in material removal rates. Moreover, tools engineered explicitly for aluminum applications feature specialized coatings and geometries tailored to mitigate built-up edges and improve surface finish. By leveraging these advancements in tooling technology, we achieve higher productivity and precision in aluminum CNC machining processes.
