Choosing The Appropriate Chamfer Cutter Tip Geometry
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 which can be employed for chamfering or beveling any kind in a wide selection of materials. Many reasons exist to chamfer an element, ranging from fluid flow and safety, to part aesthetics.
Due to the diversity of needs, tooling manufacturers offer numerous angles and sizes of chamfer cutters, as well as several types of chamfer cutter tip geometries. Harvey Tool, for instance, offers 21 different angles per side, which range from 15° to 80°, flute counts of two in order to six, and shank diameters starting at 1/8” as much as 1 “.
After locating a tool together with the exact angle they’re seeking, a person might have to pick a certain chamfer cutter tip that will are perfect for their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. The next three kinds of chamfer cutter tip styles, available from Harvey Tool, each serve a distinctive purpose.
Three Kinds of Harvey Tool Chamfer Cutters
Type I: Pointed
This kind of chamfer cutter will be the only Harvey Tool option links to a sharp point. The pointed tip permits the cutter to execute in smaller grooves, slots, and holes, compared to the opposite two sorts. This style also permits easier programming and touch-offs, since the point can be easily located. It’s because of its tip that this form of the cutter contains the longest amount of cut (together with the tool creating any finished point), in comparison to the flat end with the other chamfer cutters. With a couple of flute option, this can be the easiest sort of a chamfer cutter available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are extremely exactly like the type I style, but feature a stop that’s ground into an appartment, non-cutting tip. This flat “tip” removes the pointed area of the chamfer, the actual weakest the main tool. For that reason alteration of tool geometry, this tool emerges one more measurement based on how considerably longer the tool could be whether or not this came to a spot. This measurement is called “distance to theoretical sharp corner,” which helps with all the programming in the tool. The main benefit of the flat end of the cutter now enables multiple flutes to exist about the tapered profile from the chamfer cutter. With an increase of flutes, this chamfer has improved tool life and take care of. The flat, non-end cutting tip flat does limit its use within narrow slots, but an additional advantage is a lower profile angle with better angular velocity at the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are a greater plus more advanced type of the kind of II style. The kind III has a flat end tip with 2 flutes meeting in the center, creating a center cutting-capable version of the kind of II cutter. The center cutting geometry on this cutter can help you cut featuring its flat tip. This cutting allows the chamfer cutter to lightly reduce the top a component to the bottom of it, as an alternative to leave material behind when cutting a chamfer. There are many situations where blending of the tapered wall and floor is necessary, which is where these chamfer cutters shine. The end diameter can be held to some tight tolerance, which significantly is great for programing it.
In conclusion, there may be many suitable cutters to get a single job, and you will find many questions you need to ask ahead of picking your ideal tool. Deciding on the best angle relies on ensuring that the angle about the chamfer cutter matches the angle about the part. One needs to be aware of how the angles are classified as out, also. Is the angle an “included angle” or “angle per side?” May be the angle called off in the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer along with the longer the duration of cut, but now, interference with walls or fixtures need to be considered. Flute count comes down to material and finished. Softer materials have a tendency to 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 your job needs to be abundantly clear.
