An end mill is a type of milling cutter used in industrial milling applications. The main factors which make it unique from a drill bit is its application, geometry and manufacture. A drill bit can only cut in the axial direction while an end mill can cut in radial direction.
Solid carbide end mills are a class of end mills that use their side cutting flute edges to machine materials. They are widely used to combat edge wear when machining materials such as aluminum, brass, phenolics, etc.
The above information is just a basic introduction to carbide end mills. Before you buy your own, you need to study what type of carbide end mill fits your criteria for application and that’s why we’re here to assist you.
1. Machining Material Considerations
It is important for one to scrutinize the material using the end mill. For example, the functionality of 1018 carbon steel and D2 tool steel cannot be performed using the same approach since the two are quite different from each other in their machining qualities.
Harder materials particularly those made out of strong alloys usually require end mills with more flutes to make lighter cuts. However, when it comes to low-silicon aluminum, high speeds and feeds are used to defend the chips from evacuating the mill flutes. It should also be noticed that the helix angle of an end mill is crucial to the machining process. The angle can be adjusted to achieve the shearing angle for machining materials of different densities.
Coating is the most important factor when you need to protect your carbide end mills from catching rust or preventing it from wear and tear. When buying your ideal end mill, you should always choose the coatings which are resistant to harsh weather conditions and increased temperatures. Most industries use titanium nitride, titanium aluminum nitride and titanium carbon nitride for coating purposes.
Titanium nitride offers smooth lubrication while titanium carbon nitride is widely used in high-speed steel end mills. Titanium aluminum nitride is mainly used where heat dissipation is required.
If you know the function of your end mill well, it will be much easier for you to buy a carbide end mill. You can do this by getting an end mill with at least two or three flutes. As the general rule says, lesser the flutes on an end mill, deeper the cut that can be engraved on a workpiece.
If your application process requires side milling operations, a number of end mills attached to a fourth tooth can be put to operation before removing the metal. The number of teeth depends upon the nature of your job which in turn is dependent upon radial and axial depth of the cut.
As we all know, quality should never be compromised. Quality carbide end mills tend to last longer possessing better durability to save you from maintenance issues which is costly. We would advise you to go for UKO carbide end mills which offer best quality end mills at an affordable price.
