Milling Aluminum Milling Machining Parts Manufacturing
Efficiency and cost-effectiveness in CNC milling can be achieved through various strategies,
primarily centered on designing parts that are "Simple" and adhere to "Standard" specifications.
When you design parts with straightforward features that can be manufactured using
standard-sized tools, you enhance the likelihood of successful outcomes.
While complexity has its place in certain situations, it typically results in longer lead times and
increased costs.
For example, a part with intricate features may pose manageable challenges when crafted from
aluminum but may become considerably more complex and costly when produced from plastic,
especially in mass production scenarios.
In summary, prioritize simplicity and standardization in your designs whenever possible.
While there may be instances where complexity or specialized materials are warranted,
be mindful that they can significantly impact the milling process in terms of intensity and cost.
Product Details
In custom milling projects, CNC machine shops can work with a variety of metals and plastics,
provided they are suitable for machining.
The prevalent choice for precision CNC machining is aluminum alloys, prized for their natural
corrosion resistance.
Aluminum stands out as a favored material for CNC milling machine prototypes, thanks to its
combination of strength and machinability, enabling the precise fabrication of intricate features
in a single prototype.
Among aluminum alloys, the 6000 series is the most frequently encountered in milling machine
shops. Stainless steel alloys are another common choice due to their resistance to corrosion
and wear. Additionally, carbon steel, titanium, and nylon—a chemically resistant, robust,
durable thermoplastic—are materials often employed in CNC milling projects.
