A chamfer cutter, or even a chamfer mill, is found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are pretty straight forward tools which are employed for chamfering or beveling any area inside a wide range of materials. Many reasons exist to chamfer an element, starting from 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 as well as various kinds of chamfer cutter tip geometries. Harvey Tool, for example, offers 21 different angles per side, starting from 15° to 80°, flute counts of two in order to six, and shank diameters starting at 1/8” around 1 inch.
After obtaining a tool using the exact angle they’re searching for, a customer may need to select a certain chamfer cutter tip that might are perfect for their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. These three kinds of chamfer cutter tip styles, available from Harvey Tool, each serve a distinctive purpose.
Three Varieties of Harvey Tool Chamfer Cutters
Type I: Pointed
This style of chamfer cutter could be the only Harvey Tool option links with a sharp point. The pointed tip allows the cutter to do in smaller grooves, slots, and holes, compared to one other two sorts. This style also provides for easier programming and touch-offs, since point can be located. It’s because of its tip this version of the cutter has the longest duration of cut (using the tool coming to a finished point), in comparison to the flat end from the other chamfer cutters. With only a couple flute option, this can be the easiest sort of a chamfer cutter available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are very just like the type I style, but feature a stop that’s ground into a designated, non-cutting tip. This flat “tip” removes the pointed part of the chamfer, the weakest section of the tool. For that reason alteration of tool geometry, it is given one more measurement for the way much longer the tool could be whether or not this located a place. This measurement is recognized as “distance to theoretical sharp corner,” that helps with the programming from the tool. The main advantage of the flat end of the cutter now enables multiple flutes to exist on the tapered profile with the chamfer cutter. With increased 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 is really a lower profile angle with better angular velocity with the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are a greater and more advanced sort of the type II style. The sort III boasts a flat end tip with 2 flutes meeting in the center, creating a center cutting-capable type of the sort II cutter. The guts cutting geometry of the cutter makes it possible to cut with its flat tip. This cutting permits the chamfer cutter to lightly reduce the very top of an important part to the bottom than it, as an alternative to leave material behind when cutting a chamfer. There are many situations where blending of the tapered wall and floor is necessary, which is where these chamfer cutters shine. The end diameter is also held to a tight tolerance, which significantly aids in programing it.
In conclusion, there can be many suitable cutters for a single job, and there are many questions you must ask ahead of picking your ideal tool. Selecting the most appropriate angle is dependant on ensuring the angle on the chamfer cutter matches the angle about the part. You need to be mindful of methods the angles are known as out, too. Could be the angle an “included angle” or “angle per side?” May be the angle cancelled from the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer and the longer the duration of cut, the good news is, interference with walls or fixtures should be considered. Flute count relies on material and finish. Softer materials tend to want less flutes for much better chip evacuation, while more flutes will be finish. After addressing all these considerations, the proper design of chamfer on your job must be abundantly clear.
