A chamfer cutter, or possibly 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 used for chamfering or beveling any part within a wide variety of materials. Many reasons exist for to chamfer an important part, including fluid flow and safety, to part aesthetics.
As a result of 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, starting from 15° to 80°, flute counts of two to 6, and shank diameters starting at 1/8” around 1 inch.
After obtaining a tool using the exact angle they’re seeking, a person may need to choose a certain chamfer cutter tip that will are perfect for their operation. Common varieties of chamfer cutter tips include pointed, flat end, and end cutting. The next three forms of chamfer cutter tip styles, provided by Harvey Tool, each serve an original purpose.
Three Types of Harvey Tool Chamfer Cutters
Type I: Pointed
This style of chamfer cutter could be the only Harvey Tool option that comes into a sharp point. The pointed tip permits the cutter to complete in smaller grooves, slots, and holes, in accordance with the opposite two types. This style also enables easier programming and touch-offs, considering that the point can be easily located. It’s because of its tip until this sort of the cutter contains the longest amount of cut (together with the tool earning any finished point), in comparison to the flat end from the other sorts of chamfer cutters. With a couple flute option, this is the most straightforward version of a chamfer cutter available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are extremely like the type I style, but feature a stop that’s ground as a result of an appartment, non-cutting tip. This flat “tip” removes the pointed part of the chamfer, which is weakest part of the tool. Because of this difference in tool geometry, this tool emerges yet another measurement for how much longer the tool will be when it came to a place. This measurement is known as “distance to theoretical sharp corner,” which assists together with the programming from the tool. The advantage of the flat end of the cutter now provides for multiple flutes to exist on the tapered profile in the chamfer cutter. With increased 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 advantage is really a lower profile angle with better angular velocity on the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are a greater and more advanced sort of the kind of II style. The kind of III has a flat end tip with 2 flutes meeting in the center, making a center cutting-capable sort of the kind II cutter. The middle cutting geometry on this cutter enables us to cut with its flat tip. This cutting enables the chamfer cutter to lightly cut into the very top of an element to the bottom of it, as an alternative to leave material behind when cutting a chamfer. There are numerous situations where blending of the tapered wall and floor is required, and that is where these chamfer cutters shine. The end diameter can also be held to some tight tolerance, which significantly supports programing it.
To conclude, there may be many suitable cutters for any single job, and you will find many questions you should ask ahead of picking your ideal tool. Choosing the right angle is dependant on ensuring the angle around the chamfer cutter matches the angle for the part. You need to use caution of precisely how the angles these are known as out, also. Will be the angle an “included angle” or “angle per side?” May be the angle cancelled with the vertical or horizontal? Next, the better the shank diameter, the stronger the chamfer and the longer the duration of cut, but now, interference with walls or fixtures have to be considered. Flute count comes down to material and take care of. Softer materials often want less flutes for much better chip evacuation, while more flutes will be finish. After addressing all these considerations, the best design of chamfer on your job must be abundantly clear.
