A chamfer cutter, or a chamfer mill, are available at any machine shop, assembly floor, or hobbyist’s garage. These cutters are quite obvious tools which can be employed for chamfering or beveling any section inside a wide selection of materials. Many reasons exist to chamfer an important part, ranging from fluid flow and safety, to part aesthetics.
Due to diversity of needs, tooling manufacturers offer a number of angles and sizes of chamfer cutters, and also several types of chamfer cutter tip geometries. Harvey Tool, for example, offers 21 different angles per side, ranging from 15° to 80°, flute counts of 2 in order to six, and shank diameters starting at 1/8” approximately One inch.
After obtaining a tool with all the exact angle they’re trying to find, a person might have to select a certain chamfer cutter tip that will be perfect for their operation. Common forms of chamfer cutter tips include pointed, flat end, and end cutting. These three kinds of chamfer cutter tip styles, offered by Harvey Tool, each serve an original purpose.
Three Kinds of Harvey Tool Chamfer Cutters
Type I: Pointed
This form of chamfer cutter could be the only Harvey Tool option links to some sharp point. The pointed tip allows the cutter to execute in smaller grooves, slots, and holes, when compared with one other two types. This style also enables easier programming and touch-offs, because the point can be simply located. It’s due to its tip until this version of the cutter has the longest amount of cut (with all the tool earning any finished point), when compared to the flat end in the other types of chamfer cutters. With a couple of flute option, here is the most straightforward type of a chamfer cutter offered by Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are extremely just like the type I style, but feature a finish that’s ground as a result of a set, non-cutting tip. This flat “tip” removes the pointed area of the chamfer, which is the weakest section of the tool. For that reason change in tool geometry, it is given yet another measurement based on how much longer the tool will be if it came to a point. This measurement is termed “distance to theoretical sharp corner,” that helps using the programming in the tool. The benefit of the flat end with the cutter now allows for multiple flutes to exist on the tapered profile of the chamfer cutter. With an increase of flutes, this chamfer has improved tool life and finished. The flat, non-end cutting tip flat does limit its utilization in narrow slots, but an additional benefit can be a lower profile angle with better angular velocity on the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are a greater plus more advanced type of the type II style. The type III boasts a flat end tip with 2 flutes meeting at the center, developing a center cutting-capable sort of the type II cutter. The center cutting geometry of the cutter assists you to cut using its flat tip. This cutting permits the chamfer cutter to lightly cut into the top of the a part towards the bottom of computer, as an alternative to leave material behind when cutting a chamfer. There are several situations where blending of your tapered wall and floor is required, and this is where these chamfer cutters shine. The end diameter is additionally held with a tight tolerance, which significantly supports programing it.
To summarize, there could be many suitable cutters for the single job, and you will find many questions you need to ask prior to picking your ideal tool. Selecting the best angle relies on making sure that the angle on the chamfer cutter matches the angle about the part. One needs to use caution of the way the angles these are known as out, also. May be the angle an “included angle” or “angle per side?” Is the angle called off from the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer and the longer the length of cut, however, interference with walls or fixtures must be considered. Flute count relies on material and finish. Softer materials usually want less flutes for much better chip evacuation, while more flutes will be finish. After addressing each one of these considerations, the best style of chamfer for your job should be abundantly clear.
