Basic performance of machine tool:

This machine tool is a special deep hole drilling machine with high efficiency, high precision and high automation. The external chip drilling method (gun drilling method) is adopted. Through one continuous drilling, the processing accuracy and surface roughness can be achieved by the general drilling, expanding and reaming processes. This machine tool is controlled by digital control system, which not only has single action function, but also has automatic cycle function. Therefore, it can be suitable for small batch processing, especially for mass production processing requirements. It can drill through holes, and can also process blind or stepped holes.
