Choosing The Appropriate Chamfer Cutter Tip Geometry
A chamfer cutter, or a chamfer mill, is available at any machine shop, assembly floor, or hobbyist’s garage. These cutters are simple tools which are utilized for chamfering or beveling any area in a wide selection of materials. A lot of to chamfer a component, starting from fluid flow and safety, to part aesthetics.
Because of the diversity of needs, tooling manufacturers offer a number of angles and sizes of chamfer cutters, and also various kinds 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 two to six, and shank diameters starting at 1/8” around 1 “.
After finding a tool with all the exact angle they’re seeking, a client may need to select a certain chamfer cutter tip that will be perfect for their operation. Common kinds of chamfer cutter tips include pointed, flat end, and end cutting. The following 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 form of chamfer cutter is the only Harvey Tool option that comes to a sharp point. The pointed tip permits the cutter to do in smaller grooves, slots, and holes, in accordance with one other 2 types. This style also permits easier programming and touch-offs, since point can be simply located. It’s due to the tip this sort of the cutter has got the longest amount of cut (with the tool creating any finished point), when compared to the flat end of the other types of chamfer cutters. With only a couple flute option, this is actually the easiest sort of a chamfer cutter made available from Harvey Tool.
Type II: Flat End, Non-End Cutting
Type II chamfer cutters have become similar to the type I style, but feature an end that’s ground right down to an appartment, non-cutting tip. This flat “tip” removes the pointed section of the chamfer, the weakest section of the tool. For that reason change in tool geometry, this tool is offered yet another measurement for how considerably longer the tool could be if it located an area. This measurement is known as “distance to theoretical sharp corner,” which helps with the programming from the tool. The advantage of the flat end with the cutter now enables multiple flutes to exist on the tapered profile with the chamfer cutter. With an increase of flutes, this chamfer has improved tool life and finish. The flat, non-end cutting tip flat does limit its utilization in narrow slots, but an additional benefit can be a lower profile angle with better angular velocity at the tip.
Type III: Flat End, End Cutting
Type III chamfer cutters are a greater and more advanced form of the kind of II style. The sort III boasts a flat end tip with 2 flutes meeting at the center, setting up a center cutting-capable sort of the type II cutter. The guts cutting geometry with this cutter enables us to cut with its flat tip. This cutting permits the chamfer cutter to lightly reduce the top of a part on the bottom of it, instead of leave material behind when cutting a chamfer. There are numerous situations where blending of the tapered wall and floor should be used, and this is where these chamfer cutters shine. The tip diameter is also held with a tight tolerance, which significantly aids in programing it.
To summarize, there might be many suitable cutters for a single job, and you will find many questions you should ask just before picking your ideal tool. Choosing the right angle relies on ensuring the angle for the chamfer cutter matches the angle on the part. One needs to be cautious of methods the angles are called out, as well. May be the angle an “included angle” or “angle per side?” Could be the angle cancelled of the vertical or horizontal? Next, the larger the shank diameter, the stronger the chamfer along with the longer the duration of cut, however, interference with walls or fixtures should be considered. Flute count depends upon material and handle. Softer materials have a tendency to want less flutes for much better chip evacuation, while more flutes will help with finish. After addressing each of these considerations, the right kind of chamfer to your job needs to be abundantly clear.
