Picking The Right Chamfer Cutter Tip Geometry

Posted by

A chamfer cutter, or possibly a chamfer mill, is found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are simple tools which might be used for chamfering or beveling any area inside a wide variety of materials. There are many reasons to chamfer an element, which range from fluid flow and safety, to part aesthetics.

Due to the diversity of needs, tooling manufacturers offer a number of angles and sizes of chamfer cutters, and also different types of chamfer cutter tip geometries. Harvey Tool, for instance, 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 getting a tool with all the exact angle they’re looking for, a customer may need to choose a certain chamfer cutter tip that would are perfect for their operation. Common forms of chamfer cutter tips include pointed, flat end, and end cutting. The following three types of chamfer cutter tip styles, made available from Harvey Tool, each serve an original purpose.

Three Forms of Harvey Tool Chamfer Cutters

Type I: Pointed
This style of chamfer cutter may be the only Harvey Tool option which comes to some sharp point. The pointed tip permits the cutter to do in smaller grooves, slots, and holes, compared to the other two kinds. This style also permits easier programming and touch-offs, since the point can be easily located. It’s because of its tip until this version of the cutter has the longest duration of cut (with all the tool coming to a finished point), compared to the flat end from the other types of chamfer cutters. With a couple flute option, this can be the most simple type of a chamfer cutter made available from Harvey Tool.

Type II: Flat End, Non-End Cutting
Type II chamfer cutters are very similar to the type I style, but feature a finish that’s ground into a flat, non-cutting tip. This flat “tip” removes the pointed the main chamfer, the actual weakest section of the tool. Because of this change in tool geometry, it emerges yet another measurement for a way a lot longer the tool can be whether or not this came to a place. This measurement is termed “distance to theoretical sharp corner,” which will help with the programming in the tool. The benefit of the flat end from the cutter now provides for multiple flutes to exist on the tapered profile with the chamfer cutter. With an increase of flutes, this chamfer has improved tool life and handle. The flat, non-end cutting tip flat does limit its utilization in narrow slots, but an additional advantage can be a lower profile angle with better angular velocity at the tip.

Type III: Flat End, End Cutting
Type III chamfer cutters are a much better and much more advanced form of the kind of II style. The type III boasts a flat end tip with 2 flutes meeting in the center, creating a center cutting-capable version of the type II cutter. The guts cutting geometry of the cutter can help you cut having its flat tip. This cutting allows the chamfer cutter to lightly reduce the top of the a component to the bottom than it, as an alternative to leave material behind when cutting a chamfer. There are numerous situations where blending of your tapered wall and floor is necessary, and that is where these chamfer cutters shine. The tip diameter can also be held to some tight tolerance, which significantly helps with programing it.

To conclude, there can be many suitable cutters to get a single job, and there are many questions you should ask before picking your ideal tool. Selecting the most appropriate angle is dependant on ensuring that the angle on the chamfer cutter matches the angle about the part. You need to be mindful of the way the angles are classified as out, as well. Is the angle an “included angle” or “angle per side?” Could be the angle called off with the vertical or horizontal? Next, the better the shank diameter, the stronger the chamfer and the longer the length of cut, however, interference with walls or fixtures need to be considered. Flute count depends upon material and handle. 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 right kind of chamfer on your job must be abundantly clear.
