Picking The Proper 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 simple tools which can be utilized for chamfering or beveling any section inside a wide selection of materials. Many reasons exist to chamfer an important part, ranging 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, as well as a variety of chamfer cutter tip geometries. Harvey Tool, as an example, offers 21 different angles per side, including 15° to 80°, flute counts of 2 to 6, and shank diameters starting at 1/8” as much as 1 inch.

After locating a tool with all the exact angle they’re looking for, a client may need to pick a certain chamfer cutter tip that could be perfect for their operation. Common types of chamfer cutter tips include pointed, flat end, and end cutting. The subsequent three types of chamfer cutter tip styles, provided by Harvey Tool, each serve a unique purpose.

Three Varieties of Harvey Tool Chamfer Cutters

Type I: Pointed
This style of chamfer cutter may be the only Harvey Tool option which will come to a sharp point. The pointed tip allows the cutter to complete in smaller grooves, slots, and holes, in accordance with the opposite two kinds. This style also permits easier programming and touch-offs, since the point can be simply located. It’s because tip this form of the cutter has got the longest amount of cut (with the tool earning any finished point), in comparison to the flat end in the other chamfer cutters. With a 2 flute option, this is the most simple version 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 right down to a flat, non-cutting tip. This flat “tip” removes the pointed area of the chamfer, the actual weakest area of the tool. Due to this alternation in tool geometry, this tool is offered a different measurement for a way much longer the tool could be if it found a point. This measurement is called “distance to theoretical sharp corner,” which assists with all the programming from the tool. The benefit of the flat end with the cutter now provides for multiple flutes to exist for the tapered profile from the chamfer cutter. With an increase of 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 benefit is often 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 kind of II style. The type III boasts a flat end tip with 2 flutes meeting at the center, setting up a center cutting-capable sort of the type II cutter. The center cutting geometry with this cutter can help you cut having its flat tip. This cutting permits the chamfer cutter to lightly reduce the top of a part to the bottom from it, instead of leave material behind when cutting a chamfer. There are several situations where blending of your tapered wall and floor is needed, which is where these chamfer cutters shine. The top diameter is additionally held to a tight tolerance, which significantly helps with programing it.

To summarize, there can be many suitable cutters for a single job, and you will find many questions you must ask just before picking your ideal tool. Choosing the right angle comes down to ensuring the angle for the chamfer cutter matches the angle around the part. One should be cautious of methods the angles these are known as out, at the same time. Could be the angle an “included angle” or “angle per side?” Could be the angle cancelled of the vertical or horizontal? Next, the larger the shank diameter, the stronger the chamfer along with the longer along cut, however, interference with walls or fixtures must be considered. Flute count relies on material and handle. Softer materials tend to want less flutes for much better chip evacuation, while more flutes will help with finish. After addressing all these considerations, the best kind of chamfer on your job should be abundantly clear.
