It is just a cylindrical piece of metal from which manufacturers cut the flute. The shank is the part of the tool that does not have an edge. It runs from the tip of the bit all the way to the shank. The flute is the section of the bit that contains the cutting edge. Selecting Standard 1: Geometry End mills comprise a shank, neck, flute, and edge. Here’s everything you need to know about end mill standards for aluminum: Therefore, choosing end mill with the correct geometry, coatings, flutes, and angles, is essential. Because of this, a friction-induced fusion between the end mill and material can occur, destroying both the piece being milled and the equipment. Compared to steel, aluminum has a much lower melting point. The main challenge in machining aluminum milling is heating. Making incorrect choices could dramatically increase production costs and affect the quality of the finished product. However, if you are looking to mill thousands of items per week, then your choice of bit matters considerably. It is highly heat-resistant and offers superior machinability compared to cast.įollow our guide to find your right end mill for aluminum is so easy If you are looking to machine aluminum as a one-off, making the right end mill selection doesn’t matter a great deal. Wrought aluminum is a purer metal, making it less abrasive. It costs less to produce and contains significant quantities of other elements, including magnesium and silicone. Cast aluminum offers higher flexibility and lower tensile strength. Aluminum is suitable for advanced milling techniques of the kind found in most factories.Ģ Types of Industrial Aluminum There are two general types of industrial aluminum: cast and wrought. Not only is the metal abundant in the Earth’s crust, but it is also extremely light and flexible, making it ideal for numerous applications across industries.įurthermore, manufacturers love the metal because it is easy to machine. In this guide, we take a look at aluminum as a material, and then how to select a suitable end mill for drilling into it.Īluminum Material Profile Aluminum is one of the most machined materials on the planet. In most cases, you have a range of options that will fit the bill. The good news is that there isn’t usually one right answer unless you are doing very specialist work. And because of this, it can be hard to know which to choose for your application. Manufacturers make hundreds of different types of end mills for aluminum machining.
