A chamfer cutter, or possibly a chamfer mill, is found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are pretty straight forward tools which might be used for chamfering or beveling any kind in a wide variety of materials. There are many reasons to chamfer an element, which range from fluid flow and safety, to part aesthetics.
Because of the diversity of needs, tooling manufacturers offer many different angles and sizes of chamfer cutters, as well as different types of chamfer cutter tip geometries. Harvey Tool, for example, offers 21 different angles per side, ranging from 15° to 80°, flute counts of two to six, and shank diameters starting at 1/8” up to 1 “.
After finding a tool together with the exact angle they’re looking for, a person may need to go with a certain chamfer cutter tip that might be perfect for their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. The following three types of chamfer cutter tip styles, provided by Harvey Tool, each serve an original purpose.
Three Kinds of Harvey Tool Chamfer Cutters
Type I: Pointed
This style of chamfer cutter will be the only Harvey Tool option links with a sharp point. The pointed tip permits the cutter to perform in smaller grooves, slots, and holes, in accordance with the opposite 2 types. This style also permits easier programming and touch-offs, since the point can be simply located. It’s because of its tip that this form of the cutter contains the longest length of cut (together with the tool creating any finished point), in comparison to the flat end from the other sorts of chamfer cutters. Just a two flute option, here is the most simple sort of a chamfer cutter provided by Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are very like the type I style, but feature an end that’s ground down to a set, non-cutting tip. This flat “tip” removes the pointed area of the chamfer, the actual weakest area of the tool. For this reason change in tool geometry, it is given an additional measurement for how much longer the tool can be whether or not this stumbled on a point. This measurement is called “distance to theoretical sharp corner,” which helps together with the programming from the tool. The main advantage of the flat end of the cutter now enables multiple flutes to exist on the tapered profile of the chamfer cutter. With additional flutes, this chamfer has improved tool life and handle. The flat, non-end cutting tip flat does limit its used in narrow slots, but an additional is often a lower profile angle with better angular velocity in the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are a greater and more advanced version of the type II style. The sort III has a flat end tip with 2 flutes meeting in the center, creating a center cutting-capable version of the kind of II cutter. The center cutting geometry of the cutter enables us to cut using its flat tip. This cutting enables the chamfer cutter to lightly reduce the very top of a component to the bottom than it, instead of leave material behind when cutting a chamfer. There are several situations where blending of the tapered wall and floor is required, which is where these chamfer cutters shine. The tip diameter can be held to some tight tolerance, which significantly is great for programing it.
To summarize, there might be many suitable cutters for the single job, and you will find many questions you should ask before picking your ideal tool. Choosing the right angle is dependant on ensuring the angle on the chamfer cutter matches the angle on the part. You should use caution of precisely how the angles are classified as out, as well. Will be the angle an “included angle” or “angle per side?” Could be the angle cancelled of the vertical or horizontal? Next, the better the shank diameter, the stronger the chamfer and the longer along cut, but now, interference with walls or fixtures should be considered. Flute count comes down to material and take care of. Softer materials tend to want less flutes for much better chip evacuation, while more flutes will be finish. After addressing these considerations, the proper style of chamfer for your job should be abundantly clear.
