A chamfer cutter, or even a chamfer mill, is found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are quite obvious tools which might be used for chamfering or beveling any part inside a 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 a number of angles and sizes of chamfer cutters, and as well as several types of chamfer cutter tip geometries. Harvey Tool, as an example, offers 21 different angles per side, which range from 15° to 80°, flute counts of 2 to six, and shank diameters starting at 1/8” around 1 inch.
After getting a tool with the exact angle they’re searching for, a client may need to choose a certain chamfer cutter tip that could best suit their operation. Common forms of chamfer cutter tips include pointed, flat end, and end cutting. The next three varieties of chamfer cutter tip styles, available from Harvey Tool, each serve an exceptional purpose.
Three Types of Harvey Tool Chamfer Cutters
Type I: Pointed
This form of chamfer cutter will be the only Harvey Tool option that comes to some sharp point. The pointed tip permits the cutter to complete 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 this sort of the cutter has got the longest amount of cut (together with the tool creating any finished point), in comparison to the flat end in the other kinds of chamfer cutters. Just a 2 flute option, here is the easiest version of a chamfer cutter available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are incredibly like the type I style, but feature an end that’s ground into a flat, non-cutting tip. This flat “tip” removes the pointed part of the chamfer, the weakest part of the tool. Due to this alternation in tool geometry, this tool is offered a different measurement for the way considerably longer the tool could be when it found a point. This measurement is recognized as “distance to theoretical sharp corner,” which assists together with the programming in the tool. The main advantage of the flat end from the cutter now enables multiple flutes to exist for the tapered profile of the chamfer cutter. With an increase of flutes, this chamfer has improved tool life and handle. The flat, non-end cutting tip flat does limit its use within narrow slots, but an additional benefit is a lower profile angle with better angular velocity in the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are an improved plus much more advanced form of the kind of II style. The type III boasts a flat end tip with 2 flutes meeting in the center, creating a center cutting-capable form of the kind II cutter. The very center cutting geometry on this cutter enables us to cut featuring its flat tip. This cutting allows the chamfer cutter to lightly reduce the top of an important part on the bottom of it, as an alternative to leave material behind when cutting a chamfer. There are lots of situations where blending of a tapered wall and floor is needed, which is where these chamfer cutters shine. The end diameter can also be held into a tight tolerance, which significantly helps with programing it.
To conclude, there may be many suitable cutters to get a single job, and you will find many questions you must ask ahead of picking your ideal tool. Selecting the best angle comes down to ensuring the angle around the chamfer cutter matches the angle around the part. One needs to be cautious of methods the angles are called out, at the same time. May be the angle an “included angle” or “angle per side?” Is the angle called off from the vertical or horizontal? Next, the larger the shank diameter, the stronger the chamfer as well as the longer along cut, however, interference with walls or fixtures have to be considered. Flute count depends upon material and handle. Softer materials have a tendency to want less flutes for better chip evacuation, while more flutes will help with finish. After addressing these considerations, the proper style of chamfer for your job needs to be abundantly clear.
