Choosing The Right Chamfer Cutter Tip Geometry
A chamfer cutter, or even 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 area within a wide variety of materials. Many reasons exist to chamfer an element, starting from fluid flow and safety, to part aesthetics.
Due to the diversity of needs, tooling manufacturers offer many different angles and sizes of chamfer cutters, and also several 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 two to 6, and shank diameters starting at 1/8” around 1 inch.
After finding a tool using the exact angle they’re seeking, a client might have to select a certain chamfer cutter tip that will are perfect for their operation. Common kinds 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 Types of Harvey Tool Chamfer Cutters
Type I: Pointed
This form of chamfer cutter could be the only Harvey Tool option links into a sharp point. The pointed tip allows the cutter to perform in smaller grooves, slots, and holes, compared to the other two kinds. 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 gets the longest period of cut (using the tool coming to a finished point), when compared to flat end with the other chamfer cutters. Just a couple flute option, this can be the easiest sort of a chamfer cutter made available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are extremely similar to the type I style, but feature an end that’s ground as a result of a flat, non-cutting tip. This flat “tip” removes the pointed section of the chamfer, which is the weakest the main tool. Due to this alternation in tool geometry, this tool emerged a different measurement based on how for a long time the tool will be whether it stumbled on a point. This measurement is recognized as “distance to theoretical sharp corner,” that helps together with the programming of the tool. The benefit of the flat end of the cutter now enables multiple flutes to exist around the tapered profile with the chamfer cutter. With more flutes, this chamfer has improved tool life and finished. The flat, non-end cutting tip flat does limit its use in narrow slots, but another advantage can be a lower profile angle with better angular velocity in the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are an improved plus much 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 form of the kind II cutter. The very center cutting geometry on this cutter enables us to cut using its flat tip. This cutting allows the chamfer cutter to lightly cut into the top a part for the bottom of computer, as an alternative to leave material behind when cutting a chamfer. There are numerous situations where blending of your tapered wall and floor is required, and this is where these chamfer cutters shine. The top diameter is also held to some tight tolerance, which significantly aids in programing it.
In summary, there could be many suitable cutters to get a single job, and you will find many questions you should ask just before picking your ideal tool. Selecting the most appropriate angle relies on ensuring the angle around the chamfer cutter matches the angle for the part. You should be mindful of methods the angles are classified as out, too. May be the angle an “included angle” or “angle per side?” Will be the angle called off with the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer along with the longer along cut, the good news is, interference with walls or fixtures must be considered. Flute count comes down to material and handle. Softer materials often want less flutes for much better chip evacuation, while more flutes will help with finish. After addressing these considerations, the proper design of chamfer for your job needs to be abundantly clear.
