1. Processing of high performance parts
In the production of auto parts, the development of automotive engines to higher performance has also promoted the development of materials in a more difficult process. For example, valve seats for intake and exhaust valves are increasingly made of special alloys. Other engine parts are also beginning to use high density graphite cast iron (CGI). The demand for ever-increasing cast iron parts has also had a major impact, as new cast irons are more difficult to machine than aging-treated cast iron. Practice has proved that the use of CBN tools is the best solution for such challenges in the automotive industry.
However, in the aerospace industry, the use of complex tools may be an excellent opportunity to increase productivity. The new aircraft design will place higher demands on titanium alloys, including titanium alloy composite parts. Because of the so large demand, the processing shop cannot use existing processing techniques to meet this demand. In order to increase production capacity, many processing plants will have to increase their production speed to speed up the processing of parts. If used properly, diamond tools and diamond coatings allow these plants to process titanium parts at higher speeds.
2. Drilling of composite materials
Another application of diamond tools in the aerospace industry may have surpassed the theoretical "metalworking" because it involves composite materials, and parts made from such materials have begun to replace some metal parts more and more. Precision Dormer, a specialist in drilling, has found that the processing of composite materials is also a critical area, and the use of diamond tools and other high-performance tools can greatly increase productivity.
Mr. Gary Kirchoff is the product manager for the company and is responsible for the production of composite-related tools. He cautioned that not every drilling process has the rigidity, stability and low radial runout necessary to get the diamond tool working properly. The company continues to develop bit designs for a wide range of composite processing equipment, ranging from manual feed drilling units to the most complex CNC machines.
However, when diamond coated tools or PCD tools are applied to the drilling of composite materials, the increase in cost and productivity is also surprising. Because carbide carbide tools are fast in the processing of abrasive composites, the life of diamond tools is several times higher than the former. Its processing speed is so high that it can save a lot of time for each part that needs to be machined with many apertures. In fact, the same diamond tool can continue to drill certain metal materials, allowing diamond tools to efficiently process composite/aluminum alloy components or composite/titanium laminates.
However, not every metal or material is suitable for making PCD, CBN or diamond coated tools. In addition to composite materials for aerospace applications, other suitable materials include titanium, aluminum and hard steel. Of course, the machine tools used must also be very suitable, because such tools require higher speeds. Machines with lower speeds may not be able to exploit the potential of such tools. At the same time, there is a certain requirement for the rigidity of the machine tool, although its rigidity requirements are not as high as many people think. In recent years, the toughness of these tool materials has been considerably improved.
In addition, diamond tools and their associated tooling products are particularly suitable for long-term machining and high volume production. The reason is very simple, because the life of the tool is greatly improved. The tool's service life can be as long as this, so the shop can make the most of the tool's effective life for cutting.
Figure 7 With the modular tool, the shop does not need to set too many positions in the tool center of the machining center.
So how do users know if their processing shop has already made a profit? Mr. Graham said that a processing example of titanium in the aerospace industry can give us some inspiration. Simply put, it can be compared with the needs faced by the workshop to see where the production capacity of the workshop is limited. In the process of machining parts, you must be able to adapt to more ordering requirements or achieve higher throughput. By increasing the speed, you can achieve these productivity targets with CBN and PCD tools without having to purchase new machines. .
