A chamfer cutter, or even a chamfer mill, is available at any machine shop, assembly floor, or hobbyist’s garage. These cutters are quite obvious tools that are useful for chamfering or beveling any section in the wide selection of materials. Many reasons exist to chamfer a part, ranging from fluid flow and safety, to part aesthetics.
As a result of diversity of needs, tooling manufacturers offer a number of angles and sizes of chamfer cutters, and also various kinds of chamfer cutter tip geometries. Harvey Tool, as an illustration, offers 21 different angles per side, which range from 15° to 80°, flute counts of 2 to 6, and shank diameters starting at 1/8” around 1 inch.
After locating a tool using the exact angle they’re looking for, a person may have to select a certain chamfer cutter tip that might best suit their operation. Common varieties of chamfer cutter tips include pointed, flat end, and end cutting. The next three types of chamfer cutter tip styles, provided by Harvey Tool, each serve a distinctive purpose.
Three Kinds of Harvey Tool Chamfer Cutters
Type I: Pointed
This brand of chamfer cutter will be the only Harvey Tool option that comes with a sharp point. The pointed tip enables the cutter to perform in smaller grooves, slots, and holes, relative to another 2 types. This style also allows for easier programming and touch-offs, considering that the point can be easily located. It’s due to the tip until this version of the cutter has got the longest length of cut (using the tool coming to a finished point), when compared to flat end from the other kinds of chamfer cutters. With a two flute option, here is the most basic version of a chamfer cutter 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 finish that’s ground right down to a set, non-cutting tip. This flat “tip” removes the pointed the main chamfer, the actual weakest the main tool. Due to this alteration of tool geometry, this tool is given yet another measurement based on how for a long time the tool will be when it located a point. This measurement is called “distance to theoretical sharp corner,” which assists with all the programming with the tool. The advantage of the flat end from the cutter now enables multiple flutes to exist around the tapered profile of the chamfer cutter. With more 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 can be a lower profile angle with better angular velocity with the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are an improved and more advanced type of the sort II style. The type III boasts a flat end tip with 2 flutes meeting in the center, setting up a center cutting-capable type of the kind II cutter. The very center cutting geometry with this cutter can help you cut with its flat tip. This cutting allows the chamfer cutter to lightly reduce the top of a part on the bottom of computer, rather than leave material behind when cutting a chamfer. There are many situations where blending of an tapered wall and floor is needed, and this is where these chamfer cutters shine. The tip diameter is additionally held into a tight tolerance, which significantly aids in programing it.
To conclude, there may be many suitable cutters to get a single job, and there are many questions you should ask just before picking your ideal tool. Choosing the right angle comes down to being sure that the angle around the chamfer cutter matches the angle for the part. One should use caution of methods the angles are called out, as well. May be the angle an “included angle” or “angle per side?” Will be the angle called off from the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer and the longer the duration of cut, however, interference with walls or fixtures have to be considered. Flute count relies on material and handle. Softer materials often want less flutes for better chip evacuation, while more flutes will help with finish. After addressing each one of these considerations, the proper design of chamfer for your job needs to be abundantly clear.
