Choosing The Right Chamfer Cutter Tip Geometry
A chamfer cutter, or even a chamfer mill, are available at any machine shop, assembly floor, or hobbyist’s garage. These cutters are quite obvious tools that are employed for chamfering or beveling any part in a wide range of materials. A lot of to chamfer a component, ranging from fluid flow and safety, to part aesthetics.
Due to diversity of needs, tooling manufacturers offer a number of angles and sizes of chamfer cutters, and 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 to six, and shank diameters starting at 1/8” up to 1 “.
After locating a tool with the exact angle they’re searching for, a person might have to go with a certain chamfer cutter tip that will work best with their operation. Common forms 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 an exceptional purpose.
Three Forms of Harvey Tool Chamfer Cutters
Type I: Pointed
This form of chamfer cutter could be the only Harvey Tool option links into a sharp point. The pointed tip enables the cutter to do in smaller grooves, slots, and holes, relative to one other two kinds. This style also enables easier programming and touch-offs, since point can be located. It’s because of its tip that form of the cutter has the longest amount of cut (using the tool earning any finished point), when compared to flat end in the other kinds of chamfer cutters. With only a couple of flute option, this can be the most simple sort of a chamfer cutter offered by Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters have become exactly like the type I style, but feature an end that’s ground right down to a flat, non-cutting tip. This flat “tip” removes the pointed area of the chamfer, which is weakest part of the tool. Because of this change in tool geometry, it emerged an additional measurement for how much longer the tool can be if it found an area. This measurement is termed “distance to theoretical sharp corner,” that helps with all the programming of the tool. The advantage of the flat end from the cutter now provides for multiple flutes to exist on the tapered profile from the chamfer cutter. With an increase of flutes, this chamfer has improved tool life and finish. The flat, non-end cutting tip flat does limit its use within narrow slots, but an additional advantage is often a lower profile angle with better angular velocity on the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are an improved plus more advanced form of the kind of II style. The kind of III features a flat end tip with 2 flutes meeting at the center, developing a center cutting-capable sort of the kind of II cutter. The very center cutting geometry of the cutter makes it possible to cut featuring its flat tip. This cutting enables the chamfer cutter to lightly reduce the top an important part to the bottom from it, as opposed to leave material behind when cutting a chamfer. There are numerous situations where blending of your tapered wall and floor is needed, and that is where these chamfer cutters shine. The tip diameter is additionally held with a tight tolerance, which significantly aids in programing it.
In conclusion, there might be many suitable cutters for a single job, and there are many questions you need to ask ahead of picking your ideal tool. Selecting the most appropriate angle is dependant on ensuring that the angle around the chamfer cutter matches the angle on the part. One needs to be mindful of precisely how the angles are called out, at the same time. May be the angle an “included angle” or “angle per side?” Could be the angle called off from the vertical or horizontal? Next, the better the shank diameter, the stronger the chamfer and the longer the size of cut, but now, interference with walls or fixtures have to be considered. Flute count comes down to material and finish. Softer materials often want less flutes for better chip evacuation, while more flutes will be finish. After addressing these considerations, the best type of chamfer on your job needs to be abundantly clear.
