A chamfer cutter, or even a chamfer mill, can be 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 section within a wide variety of materials. Many reasons exist to chamfer an important part, including fluid flow and safety, to part aesthetics.
As a result of diversity of needs, tooling manufacturers offer a number of angles and sizes of chamfer cutters, and as well as different types of chamfer cutter tip geometries. Harvey Tool, as an example, offers 21 different angles per side, starting from 15° to 80°, flute counts of two to six, and shank diameters starting at 1/8” around 1 “.
After getting a tool together with the exact angle they’re looking for, a person may have to select a certain chamfer cutter tip that could are perfect for their operation. Common types of chamfer cutter tips include pointed, flat end, and end cutting. These three kinds of chamfer cutter tip styles, offered by Harvey Tool, each serve an original purpose.
Three Types of Harvey Tool Chamfer Cutters
Type I: Pointed
This kind of chamfer cutter may be the only Harvey Tool option which will come into a sharp point. The pointed tip allows the cutter to complete in smaller grooves, slots, and holes, in accordance with the other two kinds. This style also permits easier programming and touch-offs, because the point can be easily located. It’s due to the tip this sort of the cutter has the longest amount of cut (with the tool creating any finished point), compared to the flat end with the other chamfer cutters. With simply a 2 flute option, this is the easiest version of a chamfer cutter available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters are very exactly like the type I style, but feature an end that’s ground down to a designated, non-cutting tip. This flat “tip” removes the pointed the main chamfer, which is weakest area of the tool. Because of this alteration of tool geometry, it emerges an additional measurement for the way much longer the tool will be when it found a place. This measurement is termed “distance to theoretical sharp corner,” that helps with the programming in the tool. The main benefit of the flat end of the cutter now provides for multiple flutes to exist around the tapered profile of the chamfer cutter. With additional flutes, this chamfer has improved tool life and take care of. The flat, non-end cutting tip flat does limit its used in narrow slots, but an additional benefit is often 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 more advanced version of the kind of II style. The sort III possesses a flat end tip with 2 flutes meeting in the center, creating a center cutting-capable form of the type II cutter. The very center cutting geometry on this cutter makes it possible to cut with its flat tip. This cutting permits the chamfer cutter to lightly cut into the very top of an element towards the bottom of it, as opposed 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 tip diameter can be held with a tight tolerance, which significantly is great for programing it.
To conclude, there could be many suitable cutters to get a single job, and there are many questions you have to ask before picking your ideal tool. Choosing the right angle depends upon making sure that the angle on the chamfer cutter matches the angle for the part. One needs to be cautious of the way the angles are called out, too. Is the angle an “included angle” or “angle per side?” Will be the angle called off in the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer and also the longer along cut, these days, interference with walls or fixtures need to be considered. Flute count comes down to material and finish. Softer materials tend to want less flutes for better chip evacuation, while more flutes will help with finish. After addressing these considerations, the correct design of chamfer for your job must be abundantly clear.
