A chamfer cutter, or a chamfer mill, are available at any machine shop, assembly floor, or hobbyist’s garage. These cutters are quite obvious tools which might be utilized for chamfering or beveling any section in a wide variety of materials. There are many reasons to chamfer an important part, which range from fluid flow and safety, to part aesthetics.
Due to diversity of needs, tooling manufacturers offer a number of angles and sizes of chamfer cutters, and as well as different types of chamfer cutter tip geometries. Harvey Tool, as an illustration, offers 21 different angles per side, including 15° to 80°, flute counts of 2 in order to six, and shank diameters starting at 1/8” around 1 inch.
After getting a tool together with the exact angle they’re seeking, a client might have to go with a certain chamfer cutter tip that could best suit their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. The following three varieties of chamfer cutter tip styles, provided by Harvey Tool, each serve an exceptional purpose.
Three Varieties of Harvey Tool Chamfer Cutters
Type I: Pointed
This style of chamfer cutter will be the only Harvey Tool option which comes to a sharp point. The pointed tip enables the cutter to do in smaller grooves, slots, and holes, when compared with the opposite 2 types. This style also allows for easier programming and touch-offs, considering that the point can be easily located. It’s due to its tip until this type of the cutter has the longest amount of cut (using the tool coming to a finished point), in comparison to the flat end in the other sorts of chamfer cutters. With simply a 2 flute option, this is actually the most simple version of a chamfer cutter provided by Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are extremely just like the type I style, but feature a conclusion that’s ground into a designated, non-cutting tip. This flat “tip” removes the pointed section of the chamfer, the weakest section of the tool. Because of this difference in tool geometry, this tool emerges yet another measurement for the way much longer the tool could be if it came to a spot. This measurement is termed “distance to theoretical sharp corner,” that helps together with the programming with the tool. The main benefit of the flat end from the cutter now allows for multiple flutes to exist for the tapered profile with the chamfer cutter. With an increase of flutes, this chamfer has improved tool life and handle. The flat, non-end cutting tip flat does limit its use in narrow slots, but an additional benefit is a lower profile angle with better angular velocity on the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are a greater plus much more advanced version of the type II style. The kind of III possesses a flat end tip with 2 flutes meeting at the center, creating a center cutting-capable type of the type II cutter. The center cutting geometry of the cutter can help you cut featuring its flat tip. This cutting enables the chamfer cutter to lightly reduce the very top of a component towards the bottom of it, as an alternative to leave material behind when cutting a chamfer. There are lots of situations where blending of your tapered wall and floor should be used, and that is where these chamfer cutters shine. The end diameter is additionally held to some tight tolerance, which significantly is great for programing it.
In conclusion, there can be many suitable cutters for a single job, and there are many questions you need to ask ahead of picking your ideal tool. Deciding on the best angle relies on making sure that the angle on the chamfer cutter matches the angle around the part. One should be cautious of the way the angles are called out, too. Will be the angle an “included angle” or “angle per side?” Will be the angle cancelled of the vertical or horizontal? Next, the better the shank diameter, the stronger the chamfer and the longer the duration of cut, however, interference with walls or fixtures must be considered. Flute count depends upon material and take care of. Softer materials usually want less flutes for better chip evacuation, while more flutes will help with finish. After addressing each one of these considerations, the right type of chamfer for your job ought to be abundantly clear.
