Picking The Proper Chamfer Cutter Tip Geometry
A chamfer cutter, or perhaps a chamfer mill, is available at any machine shop, assembly floor, or hobbyist’s garage. These cutters are simple tools which can be useful for chamfering or beveling any kind within a wide range of materials. A lot of to chamfer an important part, starting from fluid flow and safety, to part aesthetics.
Because of the diversity of needs, tooling manufacturers offer a variety of angles and sizes of chamfer cutters, and as well as 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 2 to six, and shank diameters starting at 1/8” around 1 inch.
After obtaining a tool together with the exact angle they’re searching for, a client may have to pick a certain chamfer cutter tip that would be perfect for their operation. Common forms of chamfer cutter tips include pointed, flat end, and end cutting. The next three kinds of chamfer cutter tip styles, available from Harvey Tool, each serve an exceptional purpose.
Three Varieties of Harvey Tool Chamfer Cutters
Type I: Pointed
This style of chamfer cutter will be the only Harvey Tool option that comes to a sharp point. The pointed tip enables the cutter to do in smaller grooves, slots, and holes, compared to another two sorts. This style also provides for easier programming and touch-offs, because the point can be located. It’s due to the tip that this sort of the cutter has the longest period of cut (together with the tool coming to a finished point), in comparison to the flat end in the other types of chamfer cutters. With simply a 2 flute option, this can be the most basic type of a chamfer cutter offered by Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are extremely exactly like the type I style, but feature a conclusion that’s ground down to a designated, non-cutting tip. This flat “tip” removes the pointed section of the chamfer, the actual weakest the main tool. Because of this alteration of tool geometry, it is given one more measurement based on how for a long time the tool can be if it located an area. This measurement is recognized as “distance to theoretical sharp corner,” which will help with the programming of the tool. The benefit of the flat end in the cutter now allows for multiple flutes to exist about the tapered profile in 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 another advantage is a lower profile angle with better angular velocity with the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are a much better and more advanced sort of the kind II style. The sort III possesses a flat end tip with 2 flutes meeting at the center, setting up a center cutting-capable version of the type II cutter. The very center cutting geometry of the cutter assists you to cut featuring its flat tip. This cutting allows the chamfer cutter to lightly cut into the top an important part for the bottom of computer, rather than leave material behind when cutting a chamfer. There are lots of situations where blending of your tapered wall and floor is required, which is where these chamfer cutters shine. The tip diameter can be held into a tight tolerance, which significantly is great for programing it.
To conclude, 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. Deciding on the best angle comes down to ensuring the angle around the chamfer cutter matches the angle around the part. You should be cautious of how the angles are classified as out, at the same time. May be the angle an “included angle” or “angle per side?” May be the angle called off from the vertical or horizontal? Next, the better the shank diameter, the stronger the chamfer as well as the longer the length of cut, however, interference with walls or fixtures have to be considered. Flute count depends upon material and handle. Softer materials often want less flutes for much better chip evacuation, while more flutes will be finish. After addressing each of these considerations, the right design of chamfer on your job must be abundantly clear.
