Mills conical

In this article we consider the types of cutters which have their specific features. Namely, we will focus on cone spiral cutters and the cutters «corn».

Cutter tapered spiral

first, we’ll look at the cutter cone spiral. If to speak about where they most often apply, it is mainly these mills process high 3D relief, where, of course, roughing missing. Surface quality is very good — smaller roughness contributes to the shape of the cutter. If for any works using the cutter cone of the spiral, then, of course, for carving they will be very helpful.

Depth of the relief and the density of the workpiece material play an important role in the selection of the cutter diameter. For example, if we want the depth of the relief is about 10-15 millimeters, the conical helical cutter must have a shank diameter of 4 mm. It is possible to tell, this mill is very much needed in production. In awe of her and carvers who work on the machines hobby-level (where great depth is not obtained if not do pre-roughing).

tapered helical Cutters, with shank diameter 6 mm — are the most popular type of cutters. Relief depth can reach up to 25 millimeters. Such cutters running almost all the carvings in the furniture industry.

milling Cutter conical shank 8 mm is used in cases if you need deep relief.

with regard to design features, for example, has a large strength in the mills cone due to the cone shape. But for diameter as spheres and small angle cone — processing has been made possible for any difficult terrain.

For the manufacture of helical cone mills typically use tungsten carbide, deposition of ALTiN or ТiSiN. The cutter has a hardness of 55 HRC.

Mill «corn»

so the mill «corn», because the work surface resembles a ear of corn got its name. Most often, such a cutter should be used for treatment of plywood. Mill «corn» have cutting edges on end parts, in addition, also possess many of the cutting projections, which has a side surface of the cutting tool. All these features described above allow mills «corn» to work not only with end face but also the side. Heterogeneous cutting plywood without exfoliation fibers create a surface that is ribbed respiratornoi.

as for the diameter, which has the working part of the cutters, it may be different with the diameter of the shank. For example, the working part of the cutter has a diameter of less than 3,175 mm, and the shank under the collet 3,175 millimeters. If you use mill «corn», with a diameter of 0.8 mm, it is very convenient to handle thin veneer. Especially useful if you want curly cut. As for the tree — cutter is unsuitable for processing due to the limitations of angles, diameters. So, the mill with the diameter of the working part 6 mm has a radius of curvature of the internal corners when cutting must be not less than 3 millimetres.

Also, the mill «corn» intended for the removal of a large layer of metal. And of course, the primary processing — milling metal. Perfect for grooving and shoulder milling.

in summary we can say that the above-described cutters are quite efficient, and most importantly, very efficient, considering its versatility. And if you need to handle: textolite, plywood, fiberglass, metal – mill «corn» useful for this operation. Well, the cutter helical cone mainly applies to 3D objects.
