Selecting The Right Chamfer Cutter Tip Geometry

A chamfer cutter, or perhaps a chamfer mill, can be found at any machine shop, assembly floor, or hobbyist’s garage. These cutters are simple tools which are employed for chamfering or beveling any area within a wide selection of materials. Many reasons exist to chamfer an element, including fluid flow and safety, to part aesthetics.

After obtaining a tool using the exact angle they’re seeking, a client may have to select 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 types of chamfer cutter tip styles, offered by Harvey Tool, each serve a unique purpose.

Three Forms of Harvey Tool Chamfer Cutters

Type I: Pointed
This kind of chamfer cutter could be the only Harvey Tool option that comes with a sharp point. The pointed tip permits the cutter to perform in smaller grooves, slots, and holes, compared to the other two sorts. This style also permits easier programming and touch-offs, considering that the point can be simply located. It’s due to the tip that this form of the cutter contains the longest period of cut (together with the tool coming to a finished point), when compared to flat end with the other kinds of chamfer cutters. With only a couple of flute option, this is actually the most simple version of a chamfer cutter made available from Harvey Tool.

Type II: Flat End, Non-End Cutting
Type II chamfer cutters are extremely like the type I style, but feature an end that’s ground into a flat, non-cutting tip. This flat “tip” removes the pointed part of the chamfer, which is the weakest part of the tool. Due to this alternation in tool geometry, this tool is offered yet another measurement for the way a lot longer the tool can be whether or not this located a spot. This measurement is called “distance to theoretical sharp corner,” which assists with the programming from the tool. The benefit of the flat end in the cutter now allows for multiple flutes to exist about the tapered profile from the chamfer cutter. With increased flutes, this chamfer has improved tool life and take care of. The flat, non-end cutting tip flat does limit its use 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 greater plus much more advanced type of the sort II style. The kind III boasts a flat end tip with 2 flutes meeting in the center, creating a center cutting-capable form of the kind II cutter. The center cutting geometry on this cutter can help you cut having its flat tip. This cutting enables the chamfer cutter to lightly reduce the top of the an important part on the bottom than it, as opposed to leave material behind when cutting a chamfer. There are many situations where blending of a tapered wall and floor should be used, and that is where these chamfer cutters shine. The top diameter is additionally held into a tight tolerance, which significantly supports programing it.

To conclude, there may be many suitable cutters for a single job, and you will find many questions you must ask prior to picking your ideal tool. Selecting the most appropriate angle comes down to being sure that the angle about the chamfer cutter matches the angle for the part. One needs to use caution of precisely how the angles are classified as out, also. Could be the angle an “included angle” or “angle per side?” Is the angle cancelled in the vertical or horizontal? Next, the better the shank diameter, the stronger the chamfer as well as the longer the size of cut, however, interference with walls or fixtures have to be considered. Flute count is dependant on material and finished. Softer materials tend to want less flutes for better chip evacuation, while more flutes will help with finish. After addressing these considerations, the correct type of chamfer to your job should be abundantly clear.
