Traditional processing methods commonly used to lower the tool larger processing speed, and in general, the larger the design of the tool itself is not adapted to perform more complex processing. In order to be processed using a micro-tools, conventional machine must operate at low speed, and miniature tools brittle and easy to break. Because of the larger tool with a larger mass, and therefore the force on the chip with a certain spring effect; on the contrary, the smaller the larger the tool due to the brittle and easier breakage. Chip poor is one of the main tools of damage. In fact, due to poor micro-chip and damage the tool cutting parameters than using unreasonable damaged miniature tools more. In order to minimize the possibility of damage to the tool, you must make rapid discharge of the chips from the cutting area. Mini tool when machining requires a high spindle speed, and in order to achieve the desired spindle speed fast chip removal even higher. Define the size and processing speed of the tool: The tool includes a miniature diameter 0.250 "(6.35mm) following such a small diameter cutters and drill tool for complex, fine processing is essential, and the use of high-speed spindle for optimum processing results. There is no exact definition of high-speed cutting and absolute parameters, but one of the available spindle speed reference is defined in 25000r / min or more can be called high-speed cutting. improve the efficiency of micro-tooling to optimize the design of three related elements include miniature tools, the use of coolant low viscosity and high-speed cutting technology.
