The machine tool includes both BTA Deep hole drill (internal metal chip removal) and gun drill (external metal chip removal). Through one-time drilling, the machining accuracy and surface roughness that can only be guaranteed by drilling, expanding and reaming processes can be achieved. The mutual conversion between BTA and gun drill drilling is realized by replacing the corresponding components.
The machine tool has three independent drilling systems. The three drilling systems drill at the same time, and advance and retreat at the same time. It has high processing efficiency.
