A chamfer cutter, or even a chamfer mill, can be 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. There are many reasons to chamfer an important part, including fluid flow and safety, to part aesthetics.
Because of the diversity of needs, tooling manufacturers offer numerous angles and sizes of chamfer cutters, and as well as different types of chamfer cutter tip geometries. Harvey Tool, as an example, offers 21 different angles per side, which range from 15° to 80°, flute counts of 2 to six, and shank diameters starting at 1/8” around One inch.
After finding a tool together with the exact angle they’re searching for, a customer might have to choose a certain chamfer cutter tip that will best suit their operation. Common varieties of chamfer cutter tips include pointed, flat end, and end cutting. The following three kinds of chamfer cutter tip styles, made available from Harvey Tool, each serve a unique purpose.
Three Types of Harvey Tool Chamfer Cutters
Type I: Pointed
This kind of chamfer cutter will be the only Harvey Tool option which comes to some sharp point. The pointed tip enables the cutter to perform in smaller grooves, slots, and holes, in accordance with one other two types. This style also allows for easier programming and touch-offs, because the point can be easily located. It’s because of its tip that this form of the cutter has the longest duration of cut (with the tool creating any finished point), when compared to flat end of the other chamfer cutters. With only a 2 flute option, here is the most straightforward sort of a chamfer cutter provided by Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are incredibly just like the type I style, but feature a conclusion that’s ground right down to a designated, non-cutting tip. This flat “tip” removes the pointed part of the chamfer, which is weakest area of the tool. For that reason change in tool geometry, this tool is given one more measurement based on how a lot longer the tool could be if it stumbled on a place. This measurement is called “distance to theoretical sharp corner,” that helps together with the programming in the tool. The main advantage of the flat end of the cutter now permits multiple flutes to exist for the tapered profile of the chamfer cutter. With more flutes, this chamfer has improved tool life and take care of. The flat, non-end cutting tip flat does limit its use within narrow slots, but an additional is a lower profile angle with better angular velocity with the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are a better and more advanced form of the sort II style. The kind of III possesses a flat end tip with 2 flutes meeting at the center, setting up a center cutting-capable form of the sort II cutter. The very center cutting geometry of this cutter makes it possible to cut with its flat tip. This cutting enables the chamfer cutter to lightly cut into the top of a part for the bottom from it, as an alternative to leave material behind when cutting a chamfer. There are numerous situations where blending of your tapered wall and floor is needed, and that is where these chamfer cutters shine. The tip diameter is also held into a tight tolerance, which significantly supports programing it.
In summary, there could be many suitable cutters to get a single job, and there are many questions you have to ask just before picking your ideal tool. Deciding on the best angle is dependant on ensuring that the angle around the chamfer cutter matches the angle on the part. One should be aware of how the angles are called out, too. May be the angle an “included angle” or “angle per side?” Will be the angle cancelled of the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer and the longer the size of cut, but now, interference with walls or fixtures should be considered. Flute count is dependant on material and finished. Softer materials often want less flutes for much better chip evacuation, while more flutes will be finish. After addressing each one of these considerations, the proper kind of chamfer on your job must be abundantly clear.
