The machine structure comprises worktable, base, column, beam, and vertical tool rest. All cast iron components utilize HT250 material with resin sand casting process, followed by stress relief annealing and artificial/vibration aging treatments to ensure dimensional stability and eliminate casting defects.

Powered by a main motor with 16-speed gearbox transmission. All gears are hardened and precision ground to ensure transmission accuracy, efficiency, and reduced noise and vibration.

Integrated casting design with worktable and base. Guide surfaces feature aluminum alloy inserts with pressure oil injection forming dynamic pressure rails, providing exceptional load capacity and rotational precision.

Vertical movement along column with integrated tool feed drive mechanism, beam clamping system, and hydraulic components. Automatic lubrication pump ensures proper rail surface lubrication.

Z-axis driven by servo motor through planetary reducer for increased torque. Electromagnetic clutch switching enables complex machining operations with axis interlocking.

Comprehensive hydraulic system includes worktable dynamic pressure, main drive transmission, beam clamping, and tool rest balance systems. Ensures machine lubrication, rail stability, and system reliability.
