In this article, we consider conical mills that have a design feature – the shape of a cone. Also, have a small diameter of the tip of the cutter. This distinguishes them from other types of cutters. This mill is mainly made from tungsten carbide. Due to the taper of the cutting portion such cutters have a relatively high rigidity in the cutting process, which allows to achieve high precision and durability.on
When working with conical cutters for CNC machines it is important to accurately prescribe the geometrical parameters of the tip of the cutter. This allows to achieve very high levels of shape of the machined surface, because the main task of such tools is the acquisition of 3D surfaces. Also, this tool allows you to perform machining to a depth substantially exceeding the diameter of the shank. Why using it may not apply to those. the process of rough processing, which significantly reduces the cost of production. This interesting feature also allows you to reduce the Park of machine tools, vsledsvii its versatility, i.e. it can be used as a small slaboroslyh machines and powerful machining centers.
the type of the bevel cutter in academic sources refer to the end mills. Throughout the structure are often solid, due to the high loads during the cutting process. The core they have evenly thickened towards the endstop, and the depth of the groove decreases.
face geometry are
Spherical cutters with conical cutting part are only even number of teeth. This is due to the geometry peremychka the end. The gun nose cutters cut S shaped gun nose that allows you to provide a minimal cutting in the center of the cutter.
Mill end field may work with axial and longitudinal flow that also must be considered when designing a technical treatment process.
When the axial feed milling cutter with spherical end presetsa in detail and working teeth at the end. Her work in this case is similar to conventional drill bits. When working with longitudinal feed of the conical cutter moves perpendicular to its axis and cutting teeth arranged on the lateral surface of the cutting part.
Bevel cutter sold in stores with angles of sharpening the cutting part of the 15, 36, 60, 90 degrees. The choice of angle depends mostly on the geometry requirements of the received part and its hardness. so with the increase in angle increases the hardness of the material which can be processed by this mill.
If You for example need to the hole, for example with an angle of 60 degrees, it is better to use the cutter with the same angle just imagine.
Front and rear angle on the cutting tool, you need to choose the same considerations as that of the conventional cutters.
the harder the material, the lower corner of the front and more rear. optimal for hard materials (stainless steel, titanium alloys and the like) to use a cutter with a rake angle of the rear 3-6 and 10-12 degrees. for soft materials (e.g. aluminum) or materials with drain chips it is best to use the cutter with rake angle 8-10 degrees and a clearance angle of 15 -20 degrees. And of course cutters with extra coverage have significantly better durability, allowing them to be used largely without regard to the angles of cut.
For example, some variants of conical cutters
let’s start with the carbide conical ball mills.
Mill solid carbide tapered ball double threaded.
This kind of mill is used for operations involving treating deep reliefs (where roughing is missing). High strength mill having a small diameter of the tip contributes to the cone shape.
Usually, for the manufacture of such cutters use tungsten carbide with a hardness of 55 HRC. The working surface of the cutter may have a diameter of 0.2 — 8 mm.
K2QXР — cutter solid carbide tapered ball 2, the lead having a covering.
This bevel cutter is perfect for processing wood, plastic, MDF. And also, these cutters can handle 3D objects.
Is a conical ball carbide double cutter. This conical cutter is treated with deep reliefs (roughing missing). High strength mill having a small diameter of the tip contributes to the cone shape. To manufacture these cutters in carbide of tungsten is added a hardening impurities.
in General, these mills can be divided into three types. Accordingly, the division according to the principle of alloy grades, which are intended for operation «processing» of materials with hardness:
— up to 45 HRC;
— 55 HRC;
— 60 HRC.
This mill is processing wood, MDF, plastic and inviscid metals.
Conical carbide double ball end mill, the hardness of which is 92 HRC. Durable and long lasting. At the moment, these qualities ensure a leading position among the conical cutters. Due to the high hardness alloy cutter can boast of excellent wear resistance and durability. For example, despite the long use of the cutter, as the cutting edge remains good — it’s sharp.
Coating that reduces friction, as well as, precise edge shape, prevent Nagorniy processed material. The submission is recommended to apply 0.025 — 0.075 mm per tooth.
as for the types of works that you can accomplish such a conical cutter, it may be noted that it is possible to treat deep reliefs (roughing missing) wood (any sort), and derivative materials. High strength mill having a small diameter of the tip contributes to the cone shape. Due to this configuration, it is possible to produce work with a large clip.
Tapered end mills K2LXJ also found its use.
Is of the double end carbide conical cutter.
This mill processed deep reliefs (roughing missing). High strength mill having a small diameter of the tip contributes to the cone shape.
This mill is processing: wood, polycarbonate, chipboard, ABC.
Is a conical carbide cutter.
This cutter helps you to receive the inclined end face of the part, without involving 3D modeling.
This mill is processing wood, chipboard and MDF.
cone Mills are very efficient and at the same time, the cost is quite acceptable. So that you can safely buy these cutters for workshops and enterprises.
