Description

Technical Field

[0001] The utility model relates to the field of parts processing equipment, and more specifically, it relates to a square rail type boring and milling head used for closed cavity processing. Background Art

[0002] In the process of parts production and processing, parts with closed cavities are generally encountered. When processing closed cavity parts, the inside of the closed cavity parts is often processed by boring and milling. The milling cutter is installed on the boring and milling head, and the milling cutter is driven to rotate by the boring and milling head to mill the inside of the part, so that the inside of the part reaches the desired shape. The existing boring and milling head can generally only drive the milling cutter to rotate to mill the inside of the part. During the milling process, a large amount of metal debris will be generated. If the metal debris is not discharged in time, it will affect the subsequent processing of the part and the processing accuracy of the part, thereby affecting the production of the part. In addition, the length of the rotating shaft of the milling cutter installed in the existing boring and milling head is fixed and cannot be adjusted, so that the length that the milling cutter can penetrate into the inside of the part is limited, which makes it inconvenient to process some parts with deeper interiors, affecting the applicability of the boring and milling head.
