Compared with machine tools that cover tens of square meters or even hundreds of square meters, the tools are particularly inconspicuous in the manufacturing process, but it is these “small body†tools that often play the most amazing “big roleâ€. Productivity improvements and cost reductions require strong integration, and the first and foremost condition is the need for a suitable tool that can be adapted to a variety of processing environments (machine tools and materials).
Seco Tools is committed to developing high-efficiency cutting tools and providing low-cost machining solutions. Recently, Seco officially launched the Feedmax N-channel drill bit for aluminum alloy processing applications, further expanding the application range of the drill bit and helping the rapid development of the aerospace manufacturing industry.
Since the fourth quarter of 2009, Seco has become a Tier 1 supplier approved by Airbus France. The Feedmax N-channel drill bit is widely used by Airbus, which means that the technology of Seco's aluminum alloy drilling processing has been recognized and praised by Airbus.
The Feedmax drill has a unique N-slot design and DLC-like diamond coating technology. It exhibits excellent performance when drilling low-silicon aluminum alloys, and is especially suitable for aluminum alloy processing in the aerospace industry. Its use in the processing of aluminum alloys has increased significantly, so this series of products will make a significant contribution to further improving the processing of these materials. The N-slot drill can greatly improve machining efficiency while maintaining good accuracy throughout the life cycle.
The N-slot is slightly different from our existing M- and T-slots for aerospace applications. The N-slot can be used to keep heat to a minimum to achieve good tool life and hole quality, as reflected in the following features:
1. Cutting edge grinding. Processing these viscous materials requires a very sharp cutting edge. This is why we use only 0.01-0.02 mm edge grinding along the entire cutting edge.
2. Cone main rear corner. For the same reason, the design of the main relief is increased from a standard 10° to 12° to reduce contact with the workpiece material.
3, the blade is narrow. This unique N-slot design has a 40% narrower edge than conventional drills, which reduces the frictional heat generated between the hole and the drill during the cutting process to prevent the built-up edge of the heat from sticking to the drill bit. On the land, the quality and precision of the hole are fully guaranteed.
4. Inverted cone (axial back angle). The inverted cone (axial back angle) is 0.5 mm/100 mm, which is twice the size of the standard hole, which also reduces direct contact between the drilling and the hole surface.
5. DLC coating. This is not a diamond coating in the conventional sense. It is a low-friction coating that is designed to improve chip evacuation, which is the key to success. The main advantage is that it has the characteristics of “non-blockingâ€, which is an important issue for the processing of many aluminum alloy materials. It not only improves the chip removal capacity, but also improves the process problems that are difficult to solve in the drilling process of aluminum alloy materials. .
6. Optimize the flutes. It is very important to provide good chip evacuation. To achieve this, the flutes are designed to be wider and deeper, allowing a greater amount of chips to be discharged unimpeded.
In the drilling process, it is entirely possible to greatly increase the cutting speed if necessary. But we believe that a more moderate speed is the best for tool life and reduces the amount of heat that accumulates around the land and reduces the risk of the material sticking to the bit. By optimizing the feed per revolution, you can get a better chip shape, so the effect of chip removal is better. However, when an application has a very high cooling pressure, a higher feed per revolution can be used.
In order to process holes larger than the nominal diameter, all Seco's Feedmax drills have a diameter tolerance of m7. This ensures that the resulting hole is larger than the nominal aperture. Processing these very soft materials produces lower cutting forces, and the bore diameters typically reach H8 tolerances. However, due to some factors affecting the aperture, such as cooling pressure and coolant concentration, application stability, cutting parameters, workpiece material, etc., the resulting aperture tolerance will reach IT8 to IT9.
The development of our N-slot type is slightly different from the common process. A customer of Seco has developed a series of problems during dry drilling of aluminum alloys, including chip sticking and chip clogging, while the N-slot design provides a good solution for customers, which means we always do our best. To meet the needs of customers, to provide customers with the best solution.
In order to find the best solution for this type of material, we tried many different groove shapes, different cutting edge designs and a large number of coatings. The results show that the new N-groove bit is most suitable for the processing of wing components, mainly solving the problems of dry drilling of aluminum alloy: the material naturally adheres to the drill bit (edge ​​belt), destroying the surface roughness and A built-up edge occurs on the cutting edge.
However, due to the N-slot design and DLC coating, we tried to solve the problem of air cooling and chip evacuation for our customers. In the end, we got a remarkable result: 3600 holes were machined, the diameter deviation was 0.01mm, the surface roughness was within Ra 1.0, and there is still the possibility of continuing drilling because the cutting edge is still in perfect condition.
After machining 3,600 holes, the cutting edge is still in perfect condition
Seco's Feedmax is one of the most productive drill bits in the solid carbide drill market. As emerging modern processing continues to be the focus of attention, we will offer our customers a number of cost-saving solutions: combining higher productivity, longer tool life and better application safety.
