In the design of a machine, you can choose one of the two ideas. You can create a strong power of large machine tools, it can be used to drive a large spindle machining large tools. Drive large tools need strong power, which means that the quality must be heavier big motor. On the other hand, you can also manufacture a lightweight machine designed for micro tools. Miniature tool for high-speed cutting tools designed to withstand the cutting forces need a smaller, so the design should focus on speed and agility, without the need for using a large motor. In order to achieve high-speed machining of micro tool, the three elements (miniature tools, cooling and high-speed cutting) of each element are equally important, the lack of any one part, it is impossible to achieve high efficiency, high reliability and high flexibility processing. Conversely, if the three elements of the perfect combination, can achieve amazing processing speed and a high level of processing quality. Its processing advantages do not stop there, it also completely abolished as deburring, oil and other subsequent secondary operations. Previous 123 Next Dress on a conventional high-speed spindle CNC machine tools, it is difficult to expect high standards required for high-speed cutting. Only specifically for high-speed cutting tool design and manufacture of miniature machines to meet the stringent requirements of such processing. Advantages of using a micro tool for high-speed machining, including: cutting force is small, easy to damage the tool, low processing temperature, surface finish, cancel subsequent deburring, degreasing operations and tool vibration and so on. Up to 60000r / min spindle speed so that the processing speed is much faster than in the past, while the workpiece quality has also been improved. Today, the kind of a work in a growing, while shrinking the size of the workpiece. Trends in the manufacturing process of miniaturization requires manufacturers must make the appropriate changes.
