In micro machining, the size of parts may be very small, and there are many choices for which tool and machining scheme to use. Due to various challenges in micro machining (such as small dimensional tolerance, strict quality requirements, difficult to machine materials, etc.), it is very important to choose the right machining method. By optimizing the processing technology of small parts, we can save the materials of parts, shorten the processing cycle, reduce the cost of cutting tools, reduce the idle time of machine tools and improve the processing quality of parts. With the continuous progress of technology, in order to help improve the production efficiency of small parts, it is very important to have a reliable tool partner who can provide application support and technical consultation. Generally, it is a good starting point to determine the improvement of cutting technology according to different industries and machining types.

Manufacturing of electronic and telecommunication products
Due to the increasing requirements for the functions of components, electronic products are increasingly made of hard to process materials (such as low carbon steel and alloy steel), which has become another obstacle to the processing of these components. The micro turning tool is suitable for processing many electronic parts (such as the fine structure of the disc tray), which usually involves internal turning, grooving, cutting and threading.
Medical device manufacturing
One of the common characteristics of many medical devices is that their thread profiles are complex and changeable, and they require high dimensional accuracy. The challenge in the processing of the screws is often the large aspect ratio. The length of the screw is much larger than its diameter, which makes it more difficult to process, because the screw is easy to bend in the process of processing. In addition, many bone screws now require larger screw angle, and it is more difficult to use single edge thread cutter for processing.
Whirlwind milling (a milling process in which the cutting edge is located in the inner ring rather than the outer ring of the milling cutter) is a more productive method. This technology is very suitable for CNC machine, because the distance between the tool and guide sleeve is short, which is beneficial to enhance the support and reduce the vibration.
The screw of medical bone was processed by the technology of whirlwind milling. The whirlwind milling cutter ring with the blade installed in the inner ring rotates around the cylindrical workpiece and processes the thread. The smooth tangential cutting movement can reduce the cutting force and improve the metal removal rate.
In order to reduce the machining chatter (the biggest problem that may occur in the thread whirlwind milling) and extend the tool life, the manufacturer shall select the thread whirlwind milling cutter ring with the blade installed at unequal distance. Because it is a high-strength material to be processed, the milling insert must bear great impact, so it is necessary to select the fine grain blade matrix with high hardness and apply wear-resistant coating to prolong the tool life and improve the surface finish.
