A chamfer cutter, or perhaps a chamfer mill, can be found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are quite obvious tools which can be used for chamfering or beveling any part inside a wide array of materials. There are many reasons to chamfer an element, ranging from fluid flow and safety, to part aesthetics.
Due to diversity of needs, tooling manufacturers offer many different angles and sizes of chamfer cutters, and also various kinds of chamfer cutter tip geometries. Harvey Tool, for example, offers 21 different angles per side, including 15° to 80°, flute counts of 2 in order to six, and shank diameters starting at 1/8” approximately 1 “.
After finding a tool with all the exact angle they’re searching for, a customer may have to choose a certain chamfer cutter tip that might be perfect for their operation. Common forms of chamfer cutter tips include pointed, flat end, and end cutting. These three forms of chamfer cutter tip styles, offered by Harvey Tool, each serve an exceptional purpose.
Three Varieties of Harvey Tool Chamfer Cutters
Type I: Pointed
This brand of chamfer cutter could be the only Harvey Tool option which comes to some sharp point. The pointed tip allows the cutter to complete in smaller grooves, slots, and holes, relative to one other 2 types. This style also permits easier programming and touch-offs, because the point can be simply located. It’s because of its tip this version of the cutter contains the longest duration of cut (with all the tool coming to a finished point), compared to the flat end from the other types of chamfer cutters. With a two flute option, here is the most straightforward form of a chamfer cutter available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters have become exactly like the type I style, but feature an end that’s ground down to a set, non-cutting tip. This flat “tip” removes the pointed area of the chamfer, the actual weakest section of the tool. Due to this alternation in tool geometry, this tool emerged yet another measurement for a way considerably longer the tool will be if it located a place. This measurement is known as “distance to theoretical sharp corner,” which helps using the programming from the tool. The main advantage of the flat end from the cutter now enables multiple flutes to exist on the tapered profile with the chamfer cutter. With increased flutes, this chamfer has improved tool life and finished. The flat, non-end cutting tip flat does limit its used in narrow slots, but an additional advantage is often a lower profile angle with better angular velocity at the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are a better plus more advanced type of the sort II style. The kind of III has a flat end tip with 2 flutes meeting at the center, making a center cutting-capable type of the type II cutter. The center cutting geometry on this cutter can help you cut using its flat tip. This cutting permits the chamfer cutter to lightly reduce the top an element towards the bottom of computer, as opposed to leave material behind when cutting a chamfer. There are several situations where blending of the tapered wall and floor should be used, which is where these chamfer cutters shine. The top diameter can also be held with a tight tolerance, which significantly aids in programing it.
To conclude, there can be many suitable cutters for the single job, and there are many questions you must ask ahead of picking your ideal tool. Selecting the most appropriate angle comes down to being sure that the angle about the chamfer cutter matches the angle around the part. One needs to be mindful of how the angles these are known as out, also. Will be the angle an “included angle” or “angle per side?” Could be the angle cancelled with the vertical or horizontal? Next, the larger the shank diameter, the stronger the chamfer along with the longer the length of cut, however, 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 help with finish. After addressing each one of these considerations, the best type of chamfer on your job must be abundantly clear.
