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 can be utilized for chamfering or beveling any kind in the wide variety of materials. There are many reasons to chamfer a part, starting from fluid flow and safety, to part aesthetics.
As a result of diversity of needs, tooling manufacturers offer a variety of angles and sizes of chamfer cutters, and also 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” approximately 1 inch.
After obtaining a tool with all the exact angle they’re looking for, a client may need to pick a certain chamfer cutter tip that would be 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, provided by Harvey Tool, each serve a distinctive purpose.
Three Kinds of Harvey Tool Chamfer Cutters
Type I: Pointed
This style of chamfer cutter could be the only Harvey Tool option links into a sharp point. The pointed tip permits the cutter to execute in smaller grooves, slots, and holes, relative to the other two kinds. This style also provides for easier programming and touch-offs, since the point can easily be located. It’s because of its tip this version of the cutter gets the longest period of cut (using the tool creating any finished point), when compared to the flat end from the other sorts of chamfer cutters. With simply a couple flute option, this can be the easiest type of a chamfer cutter available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters have become exactly like the type I style, but feature a stop that’s ground as a result of a designated, non-cutting tip. This flat “tip” removes the pointed part of the chamfer, the weakest area of the tool. Due to this change in tool geometry, this tool is offered one more measurement for how a lot longer the tool could be when it located a point. This measurement is called “distance to theoretical sharp corner,” that helps with the programming of the tool. The benefit of the flat end with the cutter now allows for multiple flutes to exist around the tapered profile in 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 in 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 a much better plus more advanced form of the sort II style. The kind III has a flat end tip with 2 flutes meeting in the center, setting up a center cutting-capable version of the sort II cutter. The center cutting geometry of the cutter can help you cut using its flat tip. This cutting allows the chamfer cutter to lightly reduce the top a component towards the bottom of computer, as opposed to leave material behind when cutting a chamfer. There are lots of situations where blending of the tapered wall and floor should be used, and this is where these chamfer cutters shine. The top diameter is additionally held to some tight tolerance, which significantly aids in programing it.
To summarize, there may be many suitable cutters to get a single job, and you will find many questions you must ask ahead of picking your ideal tool. Selecting the best angle comes down to ensuring that the angle around the chamfer cutter matches the angle on the part. You should be cautious of precisely how the angles are known as out, too. May be the angle an “included angle” or “angle per side?” May be the angle cancelled from the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer and the longer the length of cut, the good news is, interference with walls or fixtures should be considered. Flute count relies on material and take care of. Softer materials often want less flutes for better chip evacuation, while more flutes will help with finish. After addressing each of these considerations, the proper kind of chamfer for the job should be abundantly clear.
