Face Milling Machine has sufficient rigidity, high efficiency, easy operation, simple structure and comprehensive performance, etc. Gantry milling machine is applicable to all kinds of large or medium mechanical black or non-ferrous metal part level, vertical surface or inclined groove milling, milling, boring head, can also be boring and drilling, and various improvements according to user needs, and undertake various types Processing and manufacturing. The face milling machine consists of a bed, a table set on the bed and a digital control circuit control system. The jacket of the gantry milling machine bed and the X-axis guide rails, and the gantry milling machine worktable are fixed on the bed. The above-mentioned activities for the installation of the gantry, the gantry also include: gantry carriage, gantry dragging and clamping activities on the X-axis deflector. Z-axis guide, installed in the gantry. Beams, beams are mounted on Z-axis carriages, Z-axis movable carriages are clamped on Z-axis guides, and beams are also held on Y-guides. Milling equipment, gantry milling machine milling equipment installation guide on the Y axis, so that under the control of the gantry CNC circuit control system, X, Y, Z three-axis milling three-dimensional space.
