A chamfer cutter, or a chamfer mill, can be found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are pretty straight forward tools which are utilized for chamfering or beveling any part within a wide array of materials. Many reasons exist to chamfer a component, ranging from fluid flow and safety, to part aesthetics.
Due to the diversity of needs, tooling manufacturers offer a number of angles and sizes of chamfer cutters, as well as different types of chamfer cutter tip geometries. Harvey Tool, for instance, offers 21 different angles per side, starting from 15° to 80°, flute counts of 2 to six, and shank diameters starting at 1/8” approximately 1 “.
After obtaining a tool with all the exact angle they’re looking for, an individual may have to go with a certain chamfer cutter tip that could are perfect for their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. The following three types of chamfer cutter tip styles, made available from Harvey Tool, each serve a distinctive purpose.
Three Forms of Harvey Tool Chamfer Cutters
Type I: Pointed
This style of chamfer cutter may be the only Harvey Tool option which comes to a sharp point. The pointed tip permits the cutter to do in smaller grooves, slots, and holes, relative to another two types. This style also enables easier programming and touch-offs, since the point can be located. It’s due to its tip that form of the cutter contains the longest duration of cut (with the tool coming to a finished point), when compared to the flat end from the other types of chamfer cutters. With a two flute option, this is actually the easiest version of a chamfer cutter made available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters have become similar to the type I style, but feature an end that’s ground right down to a flat, non-cutting tip. This flat “tip” removes the pointed section of the chamfer, the weakest part of the tool. Due to this change in tool geometry, this tool is given a different measurement for how a lot longer the tool will be whether or not this stumbled on a point. This measurement is known as “distance to theoretical sharp corner,” which assists together with the programming of the tool. The benefit of the flat end from the cutter now provides for multiple flutes to exist around the tapered profile in the chamfer cutter. With an increase of flutes, this chamfer has improved tool life and finish. The flat, non-end cutting tip flat does limit its use within narrow slots, but an additional can be a lower profile angle with better angular velocity with the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are an improved plus more advanced sort of the kind II style. The sort III boasts a flat end tip with 2 flutes meeting at the center, creating a center cutting-capable type of the sort II cutter. The guts cutting geometry with this cutter makes it possible to cut using its flat tip. This cutting enables the chamfer cutter to lightly reduce the top of the an important part towards the bottom of it, as opposed to leave material behind when cutting a chamfer. There are numerous situations where blending of an tapered wall and floor should be used, which is where these chamfer cutters shine. The tip diameter is also held to some tight tolerance, which significantly is great for programing it.
To summarize, there can be many suitable cutters for any single job, and there are many questions you have to ask just before picking your ideal tool. Choosing the right angle relies on ensuring that the angle for the chamfer cutter matches the angle for the part. You need to be cautious of precisely how the angles are classified as out, too. May be the angle an “included angle” or “angle per side?” Will be the angle called off of 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 need to be considered. Flute count relies on material and finished. Softer materials often want less flutes for better chip evacuation, while more flutes will be finish. After addressing each of these considerations, the proper style of chamfer to your job must be abundantly clear.
