Picking The Appropriate Chamfer Cutter Tip Geometry

A chamfer cutter, or a chamfer mill, can be found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are pretty straight forward tools which can be used for chamfering or beveling any kind within a wide range of materials. There are many reasons to chamfer a part, starting from fluid flow and safety, to part aesthetics.

After getting a tool together with the exact angle they’re looking for, a customer may have to choose a certain chamfer cutter tip that would work best with their operation. Common types of chamfer cutter tips include pointed, flat end, and end cutting. These three varieties 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 form of chamfer cutter could be the only Harvey Tool option links with a sharp point. The pointed tip allows the cutter to execute in smaller grooves, slots, and holes, when compared with the opposite two sorts. This style also permits easier programming and touch-offs, because the point can be located. It’s because of its tip that version of the cutter has the longest duration of cut (using the tool creating any finished point), when compared to flat end with the other kinds of chamfer cutters. Just a 2 flute option, this can be the most simple type of a chamfer cutter provided by Harvey Tool.

Type II: Flat End, Non-End Cutting
Type II chamfer cutters have become similar to the type I style, but feature a stop that’s ground down to a set, non-cutting tip. This flat “tip” removes the pointed the main chamfer, which is weakest area of the tool. Because of this difference in tool geometry, it emerges yet another measurement for the way a lot longer the tool will be whether or not this came to a place. This measurement is recognized as “distance to theoretical sharp corner,” that helps with the programming of the tool. The benefit of the flat end from the cutter now enables multiple flutes to exist around the tapered profile with 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 an additional advantage is really a lower profile angle with better angular velocity on the tip.

Type III: Flat End, End Cutting
Type III chamfer cutters are a greater plus more advanced form of the type II style. The kind of III has a flat end tip with 2 flutes meeting in the center, creating a center cutting-capable type of the type II cutter. The very center cutting geometry of the cutter assists you to cut using its flat tip. This cutting enables the chamfer cutter to lightly cut into the top of a component to the bottom of it, instead of leave material behind when cutting a chamfer. There are many situations where blending of a tapered wall and floor is necessary, and this is where these chamfer cutters shine. The tip diameter can also be held into a tight tolerance, which significantly helps with programing it.

To summarize, there can be many suitable cutters for the single job, and you will find many questions you should ask prior to picking your ideal tool. Deciding on the best angle is dependant on ensuring the angle for the chamfer cutter matches the angle on the part. You should be aware of precisely how the angles are classified as out, too. May be the angle an “included angle” or “angle per side?” Could be the angle called off with the vertical or horizontal? Next, the larger 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 finished. Softer materials have a tendency to want less flutes for better chip evacuation, while more flutes will be finish. After addressing all these considerations, the right design of chamfer on your job should be abundantly clear.
