Features of milling composite materials

  • April 3, 2017

Construction is a constantly developing area of ​​human activity. Manifestations of this continuous process are observed not only in the birth of new areas of architecture, but also in the use of new technologies and, accordingly, unknown or not highly known materials. For example, some hundred years ago, polyvinyl chloride was a material, the scope of which was an uncertain thing, despite excellent physical qualities. And about the process as the milling of PVC and no one could think. The same applies to the use of composite materials, the emergence of which history attributes almost to the times of ancient Egypt. Today, composites are one of the most popular facing materials.

What are composite materials

A composite is a special material artificially created by connecting various substances. As a result, a completely new material is obtained, consisting of several components, where one is the basis, and the rest serve as its filling, making the material stronger and tougher. In many respects, composite materials are much superior to the original ones used in their creation. Including, one of the largest advantages of composites is their ease while maintaining.

Due to the high indicator of the strength, external attractiveness and the absence of any special requirements for leaving, the aluminum composite is in particular demand.

Firstly, thanks to new technologies, this material has ceased to be a prerogative of high-tech style exclusively. Today this type of composite is produced in a wide variety of colors, from yellow to silver. In addition, the texture of the material is now not limited only to glossy smoothness. Well, as for the forms, then there is no need to speak here.

Aluminum – durable material that has very useful qualities for building: moisture – and frost resistance, low thermal conductivity. Aluminum does not know what corrosion is and is not familiar with the processes of oxidation. The life of such a material is from 35 to 50 years. That is why it is used not only as facing material, but also for the manufacture of sandwich panels.

Stages of production of elements from composite

The first stage is the manufacture of the workpiece of the set parameters.

Then, in the blanks, by means of milling, recesses are formed for connecting with other structural elements (grooves).

The next step is to process the compound elements.

In conclusion, the products are bent along the milling line and special rivets are installed at the corners of the finished product, the purpose of which is to strengthen the structure.

Features of groove processing

To process the grooves, you need to choose which of the milling to a greater extent corresponds to the requests: vertical or disk. The workpiece should be pre -placed and placed on the work surface, crushing a special guide tire.

Then a milling cutter with a finger cutter is attached to it, equipped with the device with the possibility of installing the depth of the cutter. Having set the values, you need to make a control pass and measure the distance from the place of recess to the edge. Using the received data, adjustments are made. If their need is absent, you can continue processing.

Typically, mills of vertical milling machines include mills for processing grooves of various shapes, as well as several copy rollers that limit the depth of entry.

It happens that work with a video independently made under the material is much more productive.

The disk milling cutter is not in the set of copy rollers, they are purchased separately, but they are more productive equipment. Given that vertical milling mills still requires the manufacture of some types of rollers, it is worth considering which of the mechanisms is more profitable for this particular production.

However, if you need milling composite from aluminum by pattern crooked or working with small sizes, you still can not do without finger mills.

At the construction sites for the milling process, you need to be extremely demanding, since it is precisely to the panels created in the construction of the panels that a particularly large number of claims are presented. The most important condition for the manufacture of quality products is to comply with the established parameters (in particular, the preservation of a protective polymer layer with a thickness of 0.3 mm) and the removal of chips. Non -compliance with these requirements leads to the appearance of cracks when bending the product.

Rules for processing aluminum composites

Aluminum composites are quite difficult to process materials that require special knowledge. In many ways, work with composites facilitates the use of CNC machines. The accuracy of these machines significantly expands the possibilities regarding the use of composite materials, making it possible to create products of the most diverse form and configuration.

According to the standards for aluminum composite panels, it is recommended to leave a polymer layer 0.3 – 0.4 mm under the groove, regardless of the thickness of the product.

At the construction sites for the milling process, you need to be extremely demanding, since it is precisely to the panels created in the construction of the panels that a particularly large number of claims are presented. The most important thing in the manufacture of quality products is the observance of parameters (in particular, the preservation of a protective polymer layer with a thickness of 0.3 mm) and the removal of the chips. Non -compliance with these requirements leads to the appearance of cracks when bending the product.

Thanks to the CNC machine, the processing process of composites has been greatly facilitated, and the quality of the products has improved. In addition, performance has increased and the amount of marriage has decreased.

True, despite this, sometimes the opposite happens – work with the material gives unexpected results in the form of deformations in preparation for the installation process. There can be only two reasons for this: poor -quality material or deviation from technology. The latter can be avoided if step by step follow the recommendations and norms, as well as observe all the stages provided for by the characteristics of production.
