Constructed from resin sand and wood mold castings, the machine bed’s rational structure provides a robust foundation, ensuring overall machine stability and smooth column movement. High-quality, imported ground hard-toothed racks are installed, driven by two pre-loaded gears to guarantee X-axis precision.

Made from high-quality cast iron (resin sand, wood mold casting), this sliding carriage connects to the bed via two wide guide rails (one main positioning rail, two auxiliary rails), ensuring the stability and linearity of column movement.

A double-layer frame structure of high-quality cast iron provides exceptional rigidity for headstock movement. Inlaid balance weight guide rails within the column ensure stable counterweight movement, contributing to the machine's high precision. Pre-loaded precision double-nut ball screws, driven by servo motors, manage the headstock's vertical travel along two ground guide rails.

A box-type structure cast from high-quality resin sand and wood molds, housing the main spindle components.

Ensures precise positioning at any angle. The rotary axis uses double-row cylindrical roller bearings with a central unloading device at the upper part. The rotary feed mechanism employs an AC servo motor driving a large gear ring via a backlash-eliminating reducer and double gears, automatically removing transmission gaps for high accuracy. Hydraulic floating clamping ensures reliability and stable oil film thickness during processing.

Features an operator's cabin that moves synchronously with the headstock, housing the machine control unit for convenient operation.

A hydraulic proportional valve is located at the top of the headstock housing for positioning accuracy compensation of the square ram's transverse movement; this system effectively prevents and automatically compensates for any drooping of the square ram as it extends. A pre-loaded double-nut ball screw, installed directly below the headstock body, drives the square ram.

The square ram is made of QT60-3 ductile iron material, utilizing resin sand and wood mold casting techniques. Its large cross-section effectively ensures the square ram's strength. The top of the square ram is equipped with hydraulic tie rods controlled by a proportional valve, effectively preventing the square ram from drooping and deforming when extended. Internally, the square ram is equipped with the milling spindle and the movable boring spindle (boring bar).

Features two independent hydraulic systems. A small station on the headstock's rear manages the spindle tool clamping mechanism and main drive gear shifting. A larger station, typically in the machine foundation, supplies static pressure oil, lubricating oil, and spindle cooling oil for all axes. The entire machine's hydraulic system oil is enclosed, with all oil returning to the main hydraulic station tank.
