The feeding section of the CNC boring machine can be equipped with an automatic feeder, while the receiving section can install short part and long part receivers to enable the "one-person, multiple-machines" processing mode, allowing one operator to manage multiple machines, thus saving human resources for the factory. The boring machine can be fitted with various additional facilities such as an automatic chip conveyor, high-pressure oil pump, and mist collector to form a flexible production line for automated processing. The CNC boring machine is suitable for precision composite processing of various high-precision, multi-batch, and complex-shaped shaft parts used in industries such as automotive, motorcycle, communication, refrigeration, optics, home appliances, microelectronics, electronics, and watches.
