Picking The Right Chamfer Cutter Tip Geometry
A chamfer cutter, or possibly a chamfer mill, can be found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are pretty straight forward tools which are useful for chamfering or beveling any part within a wide selection of materials. There are many reasons to chamfer an element, including fluid flow and safety, to part aesthetics.
Due to the diversity of needs, tooling manufacturers offer many different angles and sizes of chamfer cutters, as well as a variety of chamfer cutter tip geometries. Harvey Tool, as an illustration, offers 21 different angles per side, including 15° to 80°, flute counts of two to six, and shank diameters starting at 1/8” as much as One inch.
After getting a tool with all the exact angle they’re searching for, a customer might have to pick a certain chamfer cutter tip that will be perfect for their operation. Common types of chamfer cutter tips include pointed, flat end, and end cutting. The next three kinds of chamfer cutter tip styles, made available from 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 a sharp point. The pointed tip allows the cutter to complete in smaller grooves, slots, and holes, relative to another two kinds. This style also enables easier programming and touch-offs, since the point can be located. It’s due to its tip that version of the cutter has the longest length of cut (with the tool coming to a finished point), compared to the flat end in the other kinds of chamfer cutters. With a couple flute option, this can be the most simple version 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 a conclusion that’s ground right down to a set, non-cutting tip. This flat “tip” removes the pointed area of the chamfer, which is weakest the main tool. For that reason alteration of tool geometry, this tool is offered yet another measurement for how considerably longer the tool will be when it stumbled on a spot. This measurement is known as “distance to theoretical sharp corner,” which will help with all the programming from the tool. The benefit of the flat end in the cutter now provides for multiple flutes to exist for the tapered profile with the chamfer cutter. With additional 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 an additional benefit 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 and much more advanced version of the kind of II style. The sort III boasts a flat end tip with 2 flutes meeting at the center, setting up a center cutting-capable type of the type II cutter. The guts cutting geometry on this cutter can help you cut using its flat tip. This cutting allows the chamfer cutter to lightly reduce the top a component towards the bottom from it, as opposed to leave material behind when cutting a chamfer. There are lots of situations where blending of the tapered wall and floor should be used, and that is where these chamfer cutters shine. The end diameter is additionally held to a tight tolerance, which significantly aids in programing it.
To conclude, there can be many suitable cutters to get a single job, and there are many questions you should ask prior to picking your ideal tool. Choosing the right angle comes down to making sure that the angle on the chamfer cutter matches the angle about the part. You need to use caution of how the angles are known as out, as well. Could be the angle an “included angle” or “angle per side?” Will be the angle cancelled with the vertical or horizontal? Next, the better the shank diameter, the stronger the chamfer and the longer the length of cut, but now, interference with walls or fixtures need to be considered. Flute count is dependant on material and finish. Softer materials usually want less flutes for better chip evacuation, while more flutes will help with finish. After addressing all these considerations, the best design of chamfer to your job should be abundantly clear.
