In the past, high-speed cutting focused on high spindle speeds ranging from 8,000 to 100,000 rpm. Many applications are experimentally driven by the machine tool and the aerospace industry, and early high-speed cutting primarily used these aspects. However, in the workshop practice, the spindle speed during high-speed cutting is always kept in a very low range.
High-speed cutting is not a new thing. It has been in many industries such as mold manufacturing for decades. As a process, it used to be seen as a small tool for high-spindle speed machines. However, today, high-speed cutting has a wider range of applications. In the 1990s, the development of high-speed cutting focused on the overall concept, including the creation of machine tools with a spindle speed of 200,000 rpm. High spindle speeds and high feed rates are highly valued. Research institutes have shown that high speeds can have serious consequences and high risks when tool or machine tool parts do not match the application. The main factors to consider are: cutting force, surface texture, metal removal rate, tool life and safety. These studies demonstrate the importance of optimizing high-speed cutting factors for successful high-speed cutting.
Thanks to the research and development of machine tool builders, software developers, cutting tool manufacturers and research institutes, high-speed cutting (HSM) now has a wider application space. Most importantly, the actual process of high-speed cutting has not only stayed in theory, but has been applied to all aspects of the shop. The development of innovative milling tools makes high-speed cutting a more practical and profitable method in the mold manufacturing industry. Any cutting process rule, including high-speed cutting, is as effective as the machining capabilities of machine tools, software, and cutting tools. In many years of practical applications, the development of tools in high-speed cutting has moved toward higher performance. Milling is a key part of the high-speed cutting process, and its innovations have influenced the performance of milling cutters in many tooling applications. In high-speed cutting, speed is a keyword that represents the spindle speed, cutting speed or feed rate. High-speed cutting can be achieved by optimizing the milling process with high cutting speed or high feed rate.
New developments in aluminum die milling When it comes to high-speed cutting and indexable tools, safe blade fixing is a top priority. Increasingly high milling machine spindle speeds and table feeds (especially when performing aluminum cutting) result in high centrifugal forces and the resulting large load on the blade mounting components. The finite element method for analyzing load distribution is particularly valuable when developing satisfactory solutions and finding working models for indexable tools for high-speed cutting faster, and it can be used to design optimal cooling. The liquid channel and outlet structure help the chip evacuation in an optimal way. This has resulted in a new generation of high speed cutting tools for aluminum alloy cutting.
The CoroMill790 indexable end mill is an example of a tool for machining aluminum alloys at high speeds. This type of end mill is mainly used in high-speed machining processes such as cavity cutting, edge cutting, slot milling, and profiling in mold manufacturing. The fixing of the blade is realized by a specially developed blade-tool body interface. The serrated contact surface design of the bottom surface of the insert groove and the back of the blade not only maximizes the safety in high-speed milling, but also ensures the machining accuracy. The blade is evenly stressed, making the processing smoother and safer, and prolonging the tool life. The above design greatly enhances the cutting quality and improves the processing capacity.
The CoroMill790 end mill serrated contact surface design can also be widely used in face milling cutters used in aluminum machining, especially cast aluminum parts such as molds, engine blocks, gearbox housings, etc. From semi-finishing to super-finishing, the cutting speed is increased to 8000m/min. The positive rake angle of the CoroMill790 end mill can be made of cemented carbide, polycrystalline diamond (PCD) or cubic boron nitride (CBN). This design makes the milling cutter widely suitable for aluminum alloy cutting and even cast iron cutting. The high-tech CoroMill790 end mill structure is not complicated, its blade axial adjustment is simple and convenient, and it also has the advantages of cutting force balance, wide application field and precise machining allowance.
