Choosing The Best Chamfer Cutter Tip Geometry

Posted by

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 might be used for chamfering or beveling any section in a wide variety of materials. Many reasons exist to chamfer an important part, ranging from fluid flow and safety, to part aesthetics.

Due to diversity of needs, tooling manufacturers offer a variety of angles and sizes of chamfer cutters, and as well as several types 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” approximately 1 inch.

After finding a tool with the exact angle they’re searching for, a customer may have to select a certain chamfer cutter tip that would best suit their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. The following three types of chamfer cutter tip styles, offered by Harvey Tool, each serve a distinctive purpose.

Three Varieties of Harvey Tool Chamfer Cutters

Type I: Pointed
This form of chamfer cutter may be the only Harvey Tool option that comes to some sharp point. The pointed tip permits the cutter to do in smaller grooves, slots, and holes, when compared with another two sorts. This style also enables easier programming and touch-offs, because the point can be easily located. It’s due to the tip until this sort of the cutter has the longest length of cut (together with the tool creating any finished point), in comparison to the flat end with the other types of chamfer cutters. With only a couple of flute option, here is the most basic sort of a chamfer cutter provided by Harvey Tool.

Type II: Flat End, Non-End Cutting
Type II chamfer cutters are very like the type I style, but feature a finish that’s ground as a result of an appartment, non-cutting tip. This flat “tip” removes the pointed section of the chamfer, the actual weakest the main tool. For this reason difference in tool geometry, it emerges a different measurement based on how much longer the tool can be if it located a place. This measurement is called “distance to theoretical sharp corner,” that helps with all the programming with the tool. The benefit of the flat end of the cutter now permits multiple flutes to exist for the tapered profile with the chamfer cutter. With additional flutes, this chamfer has improved tool life and handle. The flat, non-end cutting tip flat does limit its use in narrow slots, but an additional can be a lower profile angle with better angular velocity on the tip.

Type III: Flat End, End Cutting
Type III chamfer cutters are a better plus much more advanced type of the kind 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 II cutter. The guts cutting geometry of the cutter assists you to cut having its flat tip. This cutting allows the chamfer cutter to lightly reduce the top of the a part towards the bottom of it, instead of leave material behind when cutting a chamfer. There are numerous situations where blending of an tapered wall and floor is required, which is where these chamfer cutters shine. The tip diameter is also held to some tight tolerance, which significantly is great for programing it.

To conclude, there could be many suitable cutters for a single job, and you will find many questions you must ask just before picking your ideal tool. Deciding on the best angle is dependant on ensuring the angle about the chamfer cutter matches the angle for the part. You need to use caution of how the angles are classified as out, too. Will be the angle an “included angle” or “angle per side?” Could be the angle called off of the vertical or horizontal? Next, the larger the shank diameter, the stronger the chamfer and also the longer the duration of cut, but now, interference with walls or fixtures need to be considered. Flute count comes down to material and handle. Softer materials tend to want less flutes for better chip evacuation, while more flutes will help with finish. After addressing these considerations, the correct style of chamfer on your job must be abundantly clear.
