Selecting The Right Chamfer Cutter Tip Geometry

Posted by

A chamfer cutter, or possibly a chamfer mill, are available at any machine shop, assembly floor, or hobbyist’s garage. These cutters are quite obvious tools which can be utilized for chamfering or beveling any kind within a wide variety of materials. There are many reasons to chamfer a component, including 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, as an illustration, 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” up to 1 “.

After finding a tool with all the exact angle they’re looking for, an individual might have to pick a certain chamfer cutter tip that could work best with their operation. Common forms of chamfer cutter tips include pointed, flat end, and end cutting. The next three kinds of chamfer cutter tip styles, offered by Harvey Tool, each serve a distinctive purpose.

Three Varieties of Harvey Tool Chamfer Cutters

Type I: Pointed
This style of chamfer cutter could be the only Harvey Tool option which will come with a sharp point. The pointed tip permits the cutter to complete in smaller grooves, slots, and holes, compared to one other 2 types. This style also enables easier programming and touch-offs, since point can be simply located. It’s because tip that version of the cutter has got the longest length of cut (with the tool coming to a finished point), compared to the flat end from the other kinds of chamfer cutters. With only a couple of flute option, this can be the most straightforward sort of a chamfer cutter provided by Harvey Tool.

Type II: Flat End, Non-End Cutting
Type II chamfer cutters are extremely just like the type I style, but feature a stop that’s ground as a result of a set, non-cutting tip. This flat “tip” removes the pointed area of the chamfer, which is weakest area of the tool. Because of this alternation in tool geometry, it emerged one more measurement for a way considerably longer the tool will be whether it stumbled on a place. This measurement is termed “distance to theoretical sharp corner,” which helps using the programming of the tool. The advantage of the flat end from the cutter now enables multiple flutes to exist around the tapered profile of the chamfer cutter. With additional flutes, this chamfer has improved tool life and finish. The flat, non-end cutting tip flat does limit its used in narrow slots, but an additional benefit is a lower profile angle with better angular velocity on the tip.

Type III: Flat End, End Cutting
Type III chamfer cutters are a greater and much more advanced version of the kind II style. The type III features a flat end tip with 2 flutes meeting in the center, developing a center cutting-capable type of the type II cutter. The middle cutting geometry with this cutter can help you cut featuring its flat tip. This cutting permits the chamfer cutter to lightly reduce the top of a part towards the bottom of computer, instead of leave material behind when cutting a chamfer. There are numerous situations where blending of an tapered wall and floor is needed, which is where these chamfer cutters shine. The top diameter is also held with a tight tolerance, which significantly is great for programing it.

To summarize, there could be many suitable cutters for the single job, and you will find many questions you must ask just before picking your ideal tool. Selecting the most appropriate angle comes down to ensuring that the angle about the chamfer cutter matches the angle for the part. One should be cautious of methods the angles are known as out, also. Could 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 along cut, the good news is, interference with walls or fixtures need to be considered. Flute count depends upon material and finish. Softer materials usually want less flutes for better chip evacuation, while more flutes will be finish. After addressing all these considerations, the correct kind of chamfer for the job should be abundantly clear.
