Introduced the RCF brand, a sustainable initiative committed to complete recycling, in pursuit of the goal of zero waste.

Initially, high energy use in production leads to substantial carbon emissions, resulting in increased carbon taxes on the final products. Secondly, the recycling technology for carbon fiber composite materials is still in its developmental stages, resulting in high-value carbon fibers being treated as waste after a single use and leading to an avoidable depletion of resources.

The “recycled carbon fiber plastic pellets” created by Thermolysis using Compounding technology are well-suited for the injection process. This results in notable enhancements in the mechanical and electrical properties of the finished injection products.

When you're choosing a cutting insert, you need to remember that not everything about it is immediately apparent. Without testing an insert on the job, it's hard to tell which is good and which is not. Choosing a cheap insert just because it looks similar to another may increase machining costs in the future. If you're unsure what type of tile to choose, it's a good idea to consult specialists in this tool. There are also some basic rules to help you narrow down your choice. Most manufacturers give their tiles numbers that tell you about their properties. To find the tiles you need, start by analyzing the catalog. Finally, if your tile isn't cutting as it should, there are some things you can look at to find a solution to the problem. Looking at the edge of the wafer through a magnifying glass may reveal the cause of the faulty cutting. If you notice that the edge is heavily worn or a bit bent, it's a sign that the tile is too soft, and you should choose a harder one. If, on the other hand, the edge of the insert is missing pieces, you should probably choose an insert that is less hard but more flexible. With the above information, you can make decisions that will improve the efficiency of your machining process and reduce its cost.

It is worth remembering that the selection of the right cutting insert depends on the machined material type, cutting speed, depth of cut, and other factors. A suitably qualified CNC operator or metalworking engineer can advise on the best type of cutting insert for a particular job.

Through Thermolysis’ distinctive equipment and technology, they have successfully achieved the recycling and reuse of carbon fibers. This accomplishment not only significantly diminishes the production of carbon fiber waste but also lowers carbon emissions.

Turning inserts are one of the most versatile types of cutting inserts. They are used in various turning processes, such as:

The next step is to identify the material to be machined. Different materials, such as steel, aluminum, titanium, or plastics, have different properties and require the right cutting inserts.

The insert shape and size should be selected according to the type of machining and the CNC machine. Cutting inserts come in many shapes, such as squares, diamonds, triangles, and circle. The shape and size of the insert affect the machining quality and life of the insert.

Multi-tool cutting tools are made of carbide. They are used for processing various metals and alloys. The material they are made is durable and resistant to high temperatures. They are often coated with additional layers to increase their performance and durability. The types of these tools depend on the shape (e.g., square, triangular) and are available in different sizes (according to ISO standards). Depending on needs, they can be reversed to utilize all cutting edges. When they are CVD coated, they are used for milling, turning steel in difficult conditions (NTP - 35), or machining gray cast iron (NTK - 25). PVD-coated inserts are used for notching classic and stainless steel (N-435) or machining these steels and surface-hardened materials (N-250).

Even after your initial insert selection, you should analyze its use in practice. CNC machining is a process of continuous improvement and optimization. Run tests, collect data, and adjust your choice based on results. You may find that different inserts are best for the different applications or machining conditions you perform.

What do they mean in practice? The seven mandatory symbols tell about the shape of the tile, the angle of inclination, and other basic characteristics of the tile. Each symbol is a letter or number that uniquely identifies a particular insert. Special tables according to DIN4983 show what each letter in the code means. Additional information about the manufacturer is written after a special character. Depending on the company, these can tell you about the edge width, edge angle, cutting material, or chip breaker shape. You can find more detailed information regarding each ISO -> here.

Cutting inserts are divided into different types. This division specifically relates to the material they are made, its shape, dimensions, and applications. The most common are turning inserts, groove-turning inserts, inserts for cutting hard materials, and thread-turning inserts. In addition, cutting inserts are available in many colors, which helps identify them.

This year, Thermolysis is back in Paris, unveiling their new brand RCF and showcasing an array of eco-friendly products crafted from recycled materials, emphasizing their commitment to complete recycling.They hope that Thermolysis’ commitment to environmental sustainability will garner greater recognition from customers, while also showcasing to the international community the dynamism of Taiwanese companies in the realms of environmental protection and innovation.

In CNC (Computer Numerical Control), there are many cutting inserts, each with its specific application in machining different materials. Below are some common types:

According to statistics, the production of one ton of newly manufactured carbon fiber typically leads to approximately 20-40 tons of CO2 emissions. In 2023, Thermolysis enlisted Germany’s TÜV Rheinland for ISO 14067 carbon footprint standard certification. The results indicate that the carbon emissions for each kilogram of its “recycled carbon fiber” total only 5.047 kilograms of carbon dioxide equivalent. In comparison to the production of new materials, Thermolysis’ recycled carbon fiber demonstrates a carbon emission level merely one-fifth that of new materials.

Introduced the RCF brand, a sustainable initiative committed to complete recycling, in pursuit of the goal of zero waste.

Cutting insert designations are essential for their proper selection in a specific cutting process. These markings follow the ISO standard and contain information on the insert's shape, dimensions, type, and cutting angles. For example, the designation "CNMG 120408" says that the inserts have a diamond shape, 80 degrees of angle, a diameter of 12.7 mm, and a thickness of 4.76 mm.

Their product line expands to include intermediate products like “recycled carbon fiber prepregs,” “recycled carbon fiber thermoplastic laminates,” and “recycled carbon fiber pipes.”

When discussing the geometry of a cutting insert, most toolmakers immediately focus on macro-geometry or the physical shape of the insert. However, more and more attention is being paid to a fast-growing area of research, namely optimizing the micro-geometry of an insert's cutting edge. At the macro level, insert geometry optimization mainly focuses on creating the most effective shape for chip control. Different insert shapes and angles can produce the best results for breaking and removing chips from the cutting area depending on the workpiece material and machining method. Designing and optimizing insert macro geometries is already a fairly advanced area of technology, well mastered by most major cutting tool manufacturers. In practice, however, it is only in recent years that technology has advanced to the point where microscopic insert geometry can be controlled. Using advanced machining techniques, it is possible to create round, oval, or beveled cutting edges on the cutting surface of an insert and even introduce fine chamfers or grooves. Through various innovative technologies, it is possible to smooth and accurately measure the blade at the microscopic level, significantly improving the life and stability of the blade machining. Further technological advances can be expected to further develop this field and bring even more significant results.

The insert material is one of the most important factors to consider. Cutting inserts can be made of various materials, such as carbide, ceramic, polycrystalline diamond (PCD). The choice of insert material should depend on the workpiece material and performance requirements.
