Over the years, drilling and attack center companies are exploring an ultrasonic vibration cutting mode (drilling and tapping machine) with a wide range of applications and reasonable processes, including research on the adaptability of machine tools. With the smooth resolution of these problems, it is expected that the micro-deep hole machining with smaller diameter will be better realized in the future, and the machining accuracy will be higher. High-speed and high-precision hole machining In addition to precision machining of the hole by CNC cutting method (drilling and tapping machine), the hole can be processed with high precision by boring and reaming. With the high speed of the machining center spindle, the boring tool can be used to perform high-speed precision machining of the hole. Cutting operations centered on milling tools are entering a high-speed, high-precision machining period. In the drilling operation of the drilling and attack center, high-speed steel twist drills are still widely used, but the gap between the processing precision and processing efficiency of the enterprises has gradually widened. NINGBO ZHENHAI BOLANG METAL PRODUCT FACTORY has relevant cnc equipment for small industrial CNC machine tools.
