A chamfer cutter, or even a chamfer mill, is available at any machine shop, assembly floor, or hobbyist’s garage. These cutters are pretty straight forward tools which are utilized for chamfering or beveling any part within a wide array of materials. Many reasons exist for to chamfer a component, which range from fluid flow and safety, to part aesthetics.
Due to the diversity of needs, tooling manufacturers offer numerous angles and sizes of chamfer cutters, as well as different types of chamfer cutter tip geometries. Harvey Tool, as an 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” around 1 inch.
After obtaining a tool with the exact angle they’re trying to find, a client may have to pick a certain chamfer cutter tip that might are perfect for their operation. Common forms of chamfer cutter tips include pointed, flat end, and end cutting. The next three varieties of chamfer cutter tip styles, made available from Harvey Tool, each serve a unique purpose.
Three Forms of Harvey Tool Chamfer Cutters
Type I: Pointed
This brand of chamfer cutter could be the only Harvey Tool option which will come to a sharp point. The pointed tip allows the cutter to execute in smaller grooves, slots, and holes, in accordance with the opposite two kinds. This style also provides for easier programming and touch-offs, because the point can be simply located. It’s because tip that type of the cutter has got the longest period of cut (with all the tool creating any finished point), when compared to the flat end of the other types of chamfer cutters. With simply a two flute option, this is the most simple form of a chamfer cutter offered by Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are very exactly like the type I style, but feature a conclusion that’s ground into a designated, non-cutting tip. This flat “tip” removes the pointed section of the chamfer, the weakest section of the tool. Because of this alteration of tool geometry, this tool emerged one more measurement for the way a lot longer the tool can be when it located a place. This measurement is termed “distance to theoretical sharp corner,” which will help together with the programming from the tool. The main advantage of the flat end with the cutter now allows for multiple flutes to exist about the tapered profile of the chamfer cutter. With additional flutes, this chamfer has improved tool life and finish. The flat, non-end cutting tip flat does limit its use within narrow slots, but another advantage is often a lower profile angle with better angular velocity at the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are a greater and more advanced sort of the sort II style. The type III possesses a flat end tip with 2 flutes meeting at the center, developing a center cutting-capable type of the kind of II cutter. The very center cutting geometry of this cutter makes it possible to cut featuring its flat tip. This cutting permits the chamfer cutter to lightly cut into the top an important part towards the bottom from it, instead of leave material behind when cutting a chamfer. There are many situations where blending of a tapered wall and floor should be used, and that is where these chamfer cutters shine. The tip diameter is also held to a tight tolerance, which significantly supports programing it.
To summarize, there can be many suitable cutters for the single job, and there are many questions you have to ask just before picking your ideal tool. Deciding on the best angle relies on making sure that the angle around the chamfer cutter matches the angle on the part. You should use caution of the way the angles are classified as out, too. Could be the angle an “included angle” or “angle per side?” Is the angle cancelled from the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer as well as the longer along cut, these days, interference with walls or fixtures need to be considered. Flute count comes down to material and finish. Softer materials usually want less flutes for much better chip evacuation, while more flutes will help with finish. After addressing each of these considerations, the proper type of chamfer for the job needs to be abundantly clear.
