A chamfer cutter, or possibly a chamfer mill, is 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 kind in the wide variety of materials. A lot of to chamfer an element, starting from fluid flow and safety, to part aesthetics.
Due to the diversity of needs, tooling manufacturers offer many different angles and sizes of chamfer cutters, as well as several types of chamfer cutter tip geometries. Harvey Tool, for example, offers 21 different angles per side, including 15° to 80°, flute counts of 2 to 6, and shank diameters starting at 1/8” around 1 “.
After locating a tool using the exact angle they’re seeking, a customer may need to choose a certain chamfer cutter tip that could be perfect for their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. The following three varieties 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 brand of chamfer cutter is the only Harvey Tool option that comes to a sharp point. The pointed tip permits the cutter to perform in smaller grooves, slots, and holes, in accordance with the opposite two sorts. This style also allows for easier programming and touch-offs, considering that the point can easily be located. It’s due to its tip that version of the cutter has got the longest duration of cut (with the tool creating any finished point), when compared to the flat end with the other sorts of chamfer cutters. With only a 2 flute option, this can be the easiest type of a chamfer cutter made available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are incredibly similar to the type I style, but feature a stop that’s ground right down to an appartment, non-cutting tip. This flat “tip” removes the pointed area of the chamfer, the actual weakest the main tool. Due to this alteration of tool geometry, it is given an additional measurement for the way considerably longer the tool can be whether or not this found an area. This measurement is termed “distance to theoretical sharp corner,” which will help together with the programming from the tool. The advantage of the flat end from the cutter now enables multiple flutes to exist on the tapered profile in 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 an additional benefit can be a lower profile angle with better angular velocity at the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are an improved and more advanced version of the kind of II style. The sort III has a flat end tip with 2 flutes meeting at the center, setting up a center cutting-capable version of the kind II cutter. The guts cutting geometry of this cutter enables us to cut featuring its flat tip. This cutting permits the chamfer cutter to lightly reduce the top of the an element towards the bottom of it, instead of leave material behind when cutting a chamfer. There are several situations where blending of the tapered wall and floor is required, and that is where these chamfer cutters shine. The tip diameter can be held to some tight tolerance, which significantly supports programing it.
In summary, there could be many suitable cutters for any single job, and there are many questions you have to ask before picking your ideal tool. Choosing the right angle relies on being sure that the angle about the chamfer cutter matches the angle on the part. You should be mindful of precisely how the angles are classified as out, too. May be the angle an “included angle” or “angle per side?” Could be the angle called off in the vertical or horizontal? Next, the better the shank diameter, the stronger the chamfer along with the longer along cut, the good news is, interference with walls or fixtures have to be considered. Flute count relies on material and finished. 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 proper style of chamfer on your job must be abundantly clear.
