How fast can you machine aluminum?
Given today’s technology, users and manufacturers generally agree that “high-speed” milling is milling with a surface speed between 3,300 and 33,000 sfm. When comparing similar operations with similar machines, aluminum will be cut at a faster speed than ferrous materials.
How do I choose an end mill for aluminum?
For aluminum milling a two- or three-flute end mill works best because this allows for larger flute areas. A core diameter of slightly less than 50 percent of cutter diameter is optimum for the same reason. An open flute design is essential for easy chip movement away from the cutting zone.
Can you mill aluminum?
Milling aluminium appears to be a remarkably easy process. Often, people who are not directly involved in machining aluminium hold misguided views. They believe that it’s enough to take a balanced, sharp, polished tool and rotate it at maximal speed, set at medium feed, and the material will cut like butter.
Can you mill aluminum with a router?
Machining aluminum with a CNC router should be possible with most any CNC router. By matching the material with the appropriate endmill bit and feed rate, you can make cutting aluminum a breeze. Always make sure to read your particular machines instruction manual fully and have a working knowledge of your equipment.
Can you mill aluminum with a drill press?
Since aluminum is a soft metal, it is relatively easy to cut, so using a drill press carefully to do so can allow you to avoid finding a mill or paying to use one to cut simple parts. Aluminum cutting endmills can be made of high-speed steel and come in two basic types, roughing and finish.
What coating is best for cutting aluminum?
The diamond and DLC coatings result in a very smooth chemically inert surface. These coatings have been found to significantly improve tool life when cutting aluminum materials. The diamond coatings were found to be the best performing coatings, but there is a considerable cost related to this type of coating.
How do you calculate the RPM of an end mill?
The following equation is used to calculate spindle speed: rpm = sfm ÷ diameter × 3.82, where diameter is the cutting tool diameter or the part diameter on a lathe in inches, and 3.82 is a constant that comes from an algebraic simplifica-tion of the more complex formula: rpm = (sfm × 12) ÷ (diameter × π).
