Picking The Right Chamfer Cutter Tip Geometry

Posted by

A chamfer cutter, or even a chamfer mill, is available at any machine shop, assembly floor, or hobbyist’s garage. These cutters are quite obvious tools that are useful for chamfering or beveling any kind inside a wide variety of materials. Many reasons exist for to chamfer an important 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 different types of chamfer cutter tip geometries. Harvey Tool, as an illustration, offers 21 different angles per side, which range from 15° to 80°, flute counts of 2 in order to six, and shank diameters starting at 1/8” approximately 1 “.

After finding a tool with all the exact angle they’re trying to find, a client may need to choose a certain chamfer cutter tip that could work best with their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. The next three types of chamfer cutter tip styles, provided by Harvey Tool, each serve an original purpose.

Three Types of Harvey Tool Chamfer Cutters

Type I: Pointed
This style of chamfer cutter is the only Harvey Tool option which comes with a sharp point. The pointed tip permits the cutter to perform in smaller grooves, slots, and holes, when compared with one other two sorts. This style also allows for easier programming and touch-offs, considering that the point can be located. It’s due to its tip until this sort of the cutter has got the longest length of cut (together with the tool earning any finished point), when compared to the flat end in the other kinds of chamfer cutters. With only a couple of flute option, this is actually 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 extremely just like the type I style, but feature a conclusion that’s ground as a result of a set, non-cutting tip. This flat “tip” removes the pointed the main chamfer, the weakest part of the tool. For that reason change in tool geometry, this tool is offered one more measurement for how for a long time the tool can be whether or not this located a point. This measurement is called “distance to theoretical sharp corner,” which helps with all the programming with the tool. The benefit of the flat end of the cutter now allows for multiple flutes to exist on the tapered profile with 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 can be a lower profile angle with better angular velocity in the tip.

Type III: Flat End, End Cutting
Type III chamfer cutters are a better plus much more advanced type of the sort II style. The sort III boasts a flat end tip with 2 flutes meeting at the center, setting up a center cutting-capable form of the kind II cutter. The guts cutting geometry of this cutter can help you cut with its flat tip. This cutting allows the chamfer cutter to lightly cut into the very top of a part towards the bottom than it, instead of leave material behind when cutting a chamfer. There are many situations where blending of an tapered wall and floor is needed, and this is where these chamfer cutters shine. The tip diameter can be held to some tight tolerance, which significantly helps with programing it.

In conclusion, there can be many suitable cutters for any single job, and there are many questions you should ask prior to picking your ideal tool. Selecting the most appropriate angle comes down to making sure that the angle for the chamfer cutter matches the angle around the part. You should be aware of the way the angles are called out, too. May be the angle an “included angle” or “angle per side?” Will be the angle called off in the vertical or horizontal? Next, the better the shank diameter, the stronger the chamfer and also the longer the size of cut, the good news is, interference with walls or fixtures must be considered. Flute count relies on material and finish. Softer materials tend to want less flutes for better chip evacuation, while more flutes will be finish. After addressing each of these considerations, the proper type of chamfer for the job needs to be abundantly clear.
