A chamfer cutter, or possibly a chamfer mill, is available 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 section inside a wide selection of materials. There are many reasons 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 also a variety of chamfer cutter tip geometries. Harvey Tool, as an illustration, offers 21 different angles per side, starting from 15° to 80°, flute counts of two to, and shank diameters starting at 1/8” up to 1 “.
After finding a tool using the exact angle they’re trying to find, an individual might have to pick 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. The following three varieties of chamfer cutter tip styles, provided by Harvey Tool, each serve an exceptional purpose.
Three Kinds of Harvey Tool Chamfer Cutters
Type I: Pointed
This brand of chamfer cutter will be the only Harvey Tool option which will come into a sharp point. The pointed tip enables the cutter to complete in smaller grooves, slots, and holes, compared to the opposite two types. This style also enables easier programming and touch-offs, since the point can be easily located. It’s due to the tip until this sort of the cutter contains the longest period of cut (with the tool coming to a finished point), when compared to flat end in the other chamfer cutters. Just a 2 flute option, here is the most simple form of a chamfer cutter made available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are extremely just like the type I style, but feature an end that’s ground into a flat, non-cutting tip. This flat “tip” removes the pointed the main chamfer, the actual weakest the main tool. Because of this change in tool geometry, it is offered an additional measurement for a way for a long time the tool will be whether or not this found a spot. This measurement is called “distance to theoretical sharp corner,” which helps with all the programming in the tool. The main benefit of the flat end with the cutter now enables multiple flutes to exist around the tapered profile in the chamfer cutter. With increased flutes, this chamfer has improved tool life and take care of. The flat, non-end cutting tip flat does limit its use within narrow slots, but an additional advantage is a lower profile angle with better angular velocity with the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are an improved and much more advanced form of the kind II style. The type III features a flat end tip with 2 flutes meeting at the center, developing a center cutting-capable version of the type II cutter. The middle cutting geometry on this cutter can help you cut using its flat tip. This cutting allows the chamfer cutter to lightly reduce the top of a component to the bottom of it, as opposed to leave material behind when cutting a chamfer. There are lots of situations where blending of an tapered wall and floor should be used, and this is where these chamfer cutters shine. The top diameter can also be held with a tight tolerance, which significantly supports programing it.
In summary, there may be many suitable cutters for the single job, and you will find many questions you need to ask before picking your ideal tool. Choosing the right angle comes down to ensuring that the angle about the chamfer cutter matches the angle on the part. You should use caution of precisely how the angles are known as out, as well. Could be the angle an “included angle” or “angle per side?” Could be the angle cancelled from the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer along with the longer the duration of cut, the good news is, interference with walls or fixtures need to be considered. Flute count depends upon material and finished. Softer materials often want less flutes for much better chip evacuation, while more flutes will help with finish. After addressing each of these considerations, the best design of chamfer to your job ought to be abundantly clear.
