In microcutting, parts may be small in size, and there are many choices about which tool and processing scheme to use. Due to the various challenges of microcutting (such as small dimensional tolerances, strict quality requirements, difficult to process materials, etc.), it is crucial to choose the right machining method. By optimizing the processing technology of small parts, we can save parts materials, shorten the processing cycle, reduce tool cost, reduce idle time of machine tools and improve the quality of parts processing. As technology continues to advance, it is important to have a reliable tool partner who can provide application support and technical advice in order to help improve the production efficiency of small parts. Often, a good starting point is to identify cutting process improvements based on different industries and machining types.

Manufacturing of electronic and telecommunications products

Due to the increasing functional requirements for parts, electronic products are increasingly manufactured from difficult to process materials, such as mild steel and alloy steel, which is another barrier to processing these parts. Micro turning tools are suitable for processing many electronic components (such as the fine structure of optical disc trays), which usually involve inner turning, grooving, cutting and threading.

Medical device manufacturing

A common feature of many medical devices is that their thread profiles are complex and variable, and they require high dimensional accuracy. The challenge of bone screw processing is often the aspect ratio. The length of the screw is much larger than its diameter, making it more difficult to process because the screw can easily bend during processing. In addition, many bone screws now require larger helical angles and are more difficult to process with single-edge threaded tools.

Threaded cyclone milling (a milling process in which the cutting edge is located in the inner ring of the cutter rather than the outer perimeter) is a more productive machining method. The process is very suitable for CNC scheming, because the distance between the tool and the guide sleeve is short, which is conducive to enhance support and reduce vibration.

Medical bone screws were processed by thread milling process. The threaded cyclone milling cutter ring with the blade mounted on the inner ring rotates around the cylindrical workpiece and processes the thread. The smooth tangential cutting motion can reduce the cutting force and increase the metal cutting rate.

To reduce machining chatter (the biggest problem that can occur with threaded cyclone milling) and to extend tool life, manufacturers should choose threaded cyclone milling rings with blades mounted at unequal intervals. Due to the processing of high strength materials, milling blade to bear a lot of impact, so must choose high hardness of fine grain blade matrix and coated with wear-resistant coating, in order to extend tool life and improve the surface finish.
