A chamfer cutter, or possibly a chamfer mill, is found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are quite obvious tools which might be useful for chamfering or beveling any section inside a wide array of materials. Many reasons exist to chamfer an important part, which range from fluid flow and safety, to part aesthetics.
Due to diversity of needs, tooling manufacturers offer many different angles and sizes of chamfer cutters, and as well as different types of chamfer cutter tip geometries. Harvey Tool, for instance, offers 21 different angles per side, including 15° to 80°, flute counts of two to six, and shank diameters starting at 1/8” up to 1 “.
After locating a tool using the exact angle they’re seeking, a client might have to select a certain chamfer cutter tip that might be perfect for their operation. Common types of chamfer cutter tips include pointed, flat end, and end cutting. The subsequent three forms of chamfer cutter tip styles, provided by Harvey Tool, each serve a unique purpose.
Three Forms of Harvey Tool Chamfer Cutters
Type I: Pointed
This style of chamfer cutter will be the only Harvey Tool option that comes with a sharp point. The pointed tip permits the cutter to execute in smaller grooves, slots, and holes, when compared with the opposite two types. This style also permits easier programming and touch-offs, since the point can easily be located. It’s due to the tip this version of the cutter has got the longest amount of cut (together with the tool earning any finished point), compared to the flat end in the other types of chamfer cutters. With a couple flute option, here is the easiest type of a chamfer cutter made available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are incredibly like the type I style, but feature a conclusion that’s ground right down to a set, non-cutting tip. This flat “tip” removes the pointed part of the chamfer, which is the weakest part of the tool. For that reason difference in tool geometry, it emerged yet another measurement for the way a lot longer the tool will be whether or not this located a place. This measurement is recognized as “distance to theoretical sharp corner,” which will help with all the programming from the tool. The main advantage of the flat end from the cutter now provides for multiple flutes to exist around the tapered profile with the chamfer cutter. With increased flutes, this chamfer has improved tool life and finish. The flat, non-end cutting tip flat does limit its use within narrow slots, but an additional benefit is a lower profile angle with better angular velocity at the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are a much better plus more advanced form of the kind of II style. The sort III features a flat end tip with 2 flutes meeting at the center, creating a center cutting-capable version of the sort II cutter. The middle cutting geometry of this cutter makes it possible to cut using its flat tip. This cutting enables the chamfer cutter to lightly cut into the top an element to the bottom of computer, as opposed to leave material behind when cutting a chamfer. There are several situations where blending of a tapered wall and floor is needed, and that is where these chamfer cutters shine. The end diameter can also be held with a tight tolerance, which significantly is great for programing it.
In conclusion, there might be many suitable cutters to get a single job, and you will find many questions you have to ask before picking your ideal tool. Choosing the right angle relies on making sure that the angle about the chamfer cutter matches the angle for the part. You should be aware of how the angles are classified as out, also. Will be the angle an “included angle” or “angle per side?” Will be the angle cancelled with the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer and the longer the duration of cut, but now, interference with walls or fixtures need to be considered. Flute count relies on material and finish. Softer materials usually want less flutes for better chip evacuation, while more flutes will help with finish. After addressing each of these considerations, the proper style of chamfer on your job ought to be abundantly clear.
