A chamfer cutter, or possibly a chamfer mill, are available at any machine shop, assembly floor, or hobbyist’s garage. These cutters are simple tools that are utilized for chamfering or beveling any part in the wide array of materials. There are many reasons to chamfer an element, including 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 various kinds 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 six, and shank diameters starting at 1/8” up to 1 “.
After obtaining a tool with the exact angle they’re looking for, a client might have to select a certain chamfer cutter tip that will work best with their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. The following three forms of chamfer cutter tip styles, provided by Harvey Tool, each serve an exceptional purpose.
Three Kinds of Harvey Tool Chamfer Cutters
Type I: Pointed
This form of chamfer cutter is the only Harvey Tool option links into a sharp point. The pointed tip enables the cutter to execute in smaller grooves, slots, and holes, in accordance with the other two types. This style also enables easier programming and touch-offs, because the point can be simply located. It’s due to the tip that version of the cutter contains the longest amount of cut (together with the tool creating any finished point), when compared to the flat end of the other chamfer cutters. With only a couple flute option, this can be the most straightforward version of a chamfer cutter made available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are incredibly exactly like the type I style, but feature a conclusion that’s ground into a set, non-cutting tip. This flat “tip” removes the pointed area of the chamfer, the weakest area of the tool. Because of this alteration of tool geometry, this tool emerges yet another measurement based on how for a long time the tool will be whether or not this stumbled on a place. This measurement is called “distance to theoretical sharp corner,” which assists using the programming in the tool. The advantage of the flat end with the cutter now allows for multiple flutes to exist for the tapered profile of 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 used in narrow slots, but another advantage 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 better and more advanced type of the sort II style. The kind III boasts a flat end tip with 2 flutes meeting in the center, developing a center cutting-capable sort of the type II cutter. The center cutting geometry of the cutter makes it possible to cut having its flat tip. This cutting permits the chamfer cutter to lightly cut into the top of the a component towards 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 this is where these chamfer cutters shine. The end diameter can be held to some tight tolerance, which significantly helps with programing it.
In conclusion, there might be many suitable cutters to get a single job, and you will find many questions you need to ask prior to picking your ideal tool. Selecting the best angle comes down to ensuring the angle for the chamfer cutter matches the angle on the part. One needs to be cautious of how the angles are classified as out, also. Will be the angle an “included angle” or “angle per side?” Will be the angle called off from the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer as well as the longer the length of cut, these days, interference with walls or fixtures must be considered. Flute count comes down to material and finished. Softer materials tend to want less flutes for better chip evacuation, while more flutes will be finish. After addressing each of these considerations, the correct style of chamfer on your job must be abundantly clear.
