Choosing The Proper Chamfer Cutter Tip Geometry

A chamfer cutter, or a chamfer mill, is available at any machine shop, assembly floor, or hobbyist’s garage. These cutters are pretty straight forward tools that are useful for chamfering or beveling any area within a wide selection of materials. Many reasons exist to chamfer an element, ranging from fluid flow and safety, to part aesthetics.

Because of the diversity of needs, tooling manufacturers offer numerous angles and sizes of chamfer cutters, and also a variety 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, and shank diameters starting at 1/8” around 1 “.

After getting a tool using the exact angle they’re searching for, a client may have to go with a certain chamfer cutter tip that would best suit their operation. Common forms of chamfer cutter tips include pointed, flat end, and end cutting. The next three varieties of chamfer cutter tip styles, offered by Harvey Tool, each serve a distinctive purpose.

Three Forms of Harvey Tool Chamfer Cutters

Type I: Pointed
This brand of chamfer cutter could be the only Harvey Tool option which comes to some sharp point. The pointed tip permits the cutter to complete in smaller grooves, slots, and holes, compared to another 2 types. This style also provides for easier programming and touch-offs, because the point can be simply located. It’s because of its tip until this sort of the cutter has the longest amount of cut (together with the tool earning any finished point), when compared to flat end with the other chamfer cutters. With only a 2 flute option, this can be the easiest type of a chamfer cutter provided by Harvey Tool.

Type II: Flat End, Non-End Cutting
Type II chamfer cutters are incredibly exactly like the type I style, but feature a conclusion that’s ground as a result of an appartment, non-cutting tip. This flat “tip” removes the pointed section of the chamfer, which is the weakest section of the tool. Because of this difference in tool geometry, this tool is given one more measurement for the way much longer the tool would be whether or not this stumbled on a point. This measurement is known as “distance to theoretical sharp corner,” which assists with the programming from the tool. The advantage of the flat end in the cutter now enables multiple flutes to exist on the tapered profile in the chamfer cutter. With an increase of flutes, this chamfer has improved tool life and take care of. The flat, non-end cutting tip flat does limit its used in narrow slots, but another advantage is really a lower profile angle with better angular velocity with the tip.

Type III: Flat End, End Cutting
Type III chamfer cutters are an improved plus more advanced form of the sort II style. The type III has a flat end tip with 2 flutes meeting in the center, creating a center cutting-capable form of the sort II cutter. The very center cutting geometry with this cutter makes it possible to cut having its flat tip. This cutting allows the chamfer cutter to lightly cut into the top of the an important part to the bottom from it, rather than leave material behind when cutting a chamfer. There are many situations where blending of an tapered wall and floor is necessary, which is where these chamfer cutters shine. The end diameter is additionally held into a tight tolerance, which significantly supports programing it.

To conclude, there can be many suitable cutters for a single job, and there are many questions you need to ask just before picking your ideal tool. Choosing the right angle depends upon ensuring the angle on the chamfer cutter matches the angle around the part. You need to be mindful of the way the angles are called out, as well. Could be the angle an “included angle” or “angle per side?” May be the angle cancelled of the vertical or horizontal? Next, the better the shank diameter, the stronger the chamfer and the longer along cut, the good news is, interference with walls or fixtures should be considered. Flute count depends upon material and finish. Softer materials have a tendency to want less flutes for better chip evacuation, while more flutes will help with finish. After addressing these considerations, the best type of chamfer to your job must be abundantly clear.
