Choosing The Right Chamfer Cutter Tip Geometry

A chamfer cutter, or a chamfer mill, is found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are pretty straight forward tools that are utilized for chamfering or beveling any area in a wide variety of materials. Many reasons exist for to chamfer a component, starting from fluid flow and safety, to part aesthetics.

Due to diversity of needs, tooling manufacturers offer a variety of angles and sizes of chamfer cutters, and also 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 in order to six, and shank diameters starting at 1/8” around 1 “.

After obtaining a tool together with the exact angle they’re searching for, a customer might have to select a certain chamfer cutter tip that could are perfect for their operation. Common forms of chamfer cutter tips include pointed, flat end, and end cutting. The following three kinds of chamfer cutter tip styles, made available from Harvey Tool, each serve an original purpose.

Three Varieties of Harvey Tool Chamfer Cutters

Type I: Pointed
This brand of chamfer cutter may be the only Harvey Tool option which comes to a sharp point. The pointed tip allows the cutter to execute in smaller grooves, slots, and holes, compared to one other 2 types. This style also enables easier programming and touch-offs, since the point can be easily located. It’s because of its tip until this version of the cutter has the longest amount of cut (with all the tool creating any finished point), compared to the flat end in the other kinds of chamfer cutters. With a couple flute option, here is the most straightforward form of a chamfer cutter offered by Harvey Tool.

Type II: Flat End, Non-End Cutting
Type II chamfer cutters are incredibly like the type I style, but feature a stop that’s ground down to a set, non-cutting tip. This flat “tip” removes the pointed the main chamfer, the actual weakest area of the tool. For that reason change in tool geometry, it emerges yet another measurement based on how considerably longer the tool could be whether or not this located a spot. This measurement is known as “distance to theoretical sharp corner,” that helps with all the programming in the tool. The benefit of the flat end of the cutter now allows for multiple flutes to exist around the tapered profile in 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 use within narrow slots, but an additional advantage can be a lower profile angle with better angular velocity on the tip.

Type III: Flat End, End Cutting
Type III chamfer cutters are a better and much more advanced sort of the kind of II style. The sort III boasts a flat end tip with 2 flutes meeting at the center, developing a center cutting-capable sort of the type II cutter. The very center cutting geometry of this cutter enables us to cut with its flat tip. This cutting enables the chamfer cutter to lightly reduce the top of a component to the bottom of computer, as an alternative to leave material behind when cutting a chamfer. There are lots of situations where blending of an tapered wall and floor is needed, and this is where these chamfer cutters shine. The tip diameter can be held with a tight tolerance, which significantly supports programing it.

To summarize, there can be many suitable cutters for the single job, and there are many questions you must ask before picking your ideal tool. Deciding on the best angle comes down to ensuring the angle on the chamfer cutter matches the angle about the part. You need to use caution of methods the angles are called out, as well. Could be the angle an “included angle” or “angle per side?” Will be the angle called off with the vertical or horizontal? Next, the greater the shank diameter, the stronger the chamfer along with the longer the size of cut, the good news is, interference with walls or fixtures must be considered. Flute count relies on material and handle. Softer materials often want less flutes for better chip evacuation, while more flutes will help with finish. After addressing each one of these considerations, the best type of chamfer on your job should be abundantly clear.
