Road Milling Tools Good Processing Performance And Safety
- Oct 31, 2017 -

In the actual process of titanium alloy will encounter a lot of factors must be considered. Based on this, the titanium alloy milling process and the main processing methods for a long time is different. Two new Road Milling Tools solutions and applications continue to evolve and offer new possibilities for titanium milling. Compared with many other materials, the potential for successful processing of titanium alloy is much smaller and the processing performance is different. Due to the relatively large change in machinability of the titanium alloy, this affects the machining method and the selection of the tool and the machining process, but with the processing of any other alloy, the need for more careful planning - from the machine to select the machine for the details of the cutting To program. Although the characteristics of the parts in the aerospace industry are quite similar, the size and shape vary, so the choice of machine tools, fixtures, coolants, tools, machining methods and cutting parameters is not the same. Due to the limited space of the magazine, the flexibility (flexibility) of the process is the primary condition. For the production efficiency and ability, the type of tool holder and the adjustment of the tool are the key factors.

As roughing and finishing processes must be planned according to different parameters, titanium alloy milling associated with different applications is also possible for indexable and overall carbide cutting tools. The size and shape to be machined and the appropriate tool type are the first determinants. The indexable tool removes the material from the highest efficiency and is now considered the first choice for roughing, and it is unrivaled in large and flat surface finishing. The overall carbide cutting tool is widely used in semi-finishing and finishing processes. When the radius of the indexable blade tool, the size of the cavity and the slot is too small, the overall carbide tool is also an ideal solution.

The programming data for the parameters of the part to be machined is the basis for selecting the dedicated Road Milling Tools. Since the maximum metal removal rate should be balanced with the economic tool life, based on this, other tool variables can be determined. For titanium alloys, the basic factors of the tool include the use of carbide material, the cutting edge is sharp and strong, and has a relatively large positive rake angle. These elements can meet the special heat resistance and chemical requirements of titanium alloys. In the case of grooved and tool materials, indexable blade technology has undergone a long process of development, and it is becoming a cost-effective solution to replace a large number of existing carbide cutting tools, even for medium and large Tool.

Radial milling is ideal for titanium processing. However, the large radial depth of cut will greatly shorten the life of the tool, and the large axial cutting depth of the cutting temperature has little effect, so it will not affect the tool life in the same way. Therefore, the use of dense pitch milling cutter, while using 30% of the radial depth of cut and the specific application of the maximum allowable axial depth is the best way to effectively remove titanium alloy material.

As a result, the long edge cutter is suitable for many titanium alloy parts of the side of the rough and fine milling. The long helical edge of the long edge cutter is well suited for large radial milling in titanium processing. Indexable blade Long edge tool consists of multiple rows of blades, which are the same as the continuous grinding of the overall carbide cutting edge. At present, from the bottom of the tool along the outer circumference of the array of indexable inserts have reached the titanium alloy to achieve good processing performance and safety limits. Large-size chip flutes that can achieve efficient chip removal are required and combined with efficient front rains and sharp blades to form an indexable long edge cutter that achieves excellent machining performance.

For titanium milling, the stable clamping of the cutting insert is critical, and even during roughing, any movement of the cutting insert causes uneven wear and puts the cutting edge at risk. A slight wear will cause the cutting edge to become blunt during the titanium alloy cutting process, thereby accelerating wear and causing damage to the tool. For a row of closely fixed continuous blades, the axial support of the insert is particularly difficult, resulting in excessive reliance on the blade screws. Therefore, in the use of long blade cutter, the best way to obtain outstanding performance is a strong interface between the blade and the blade body. The blade holder must have a definite support and locking device, taking into account the axial force and the rotational force.
