Structural form

This machine tool features two sets of mobile units, consisting of a slide, column, headstock, and control system, arranged on a common bed guideway. Each unit features a single-column layout with a side-mounted headstock, a movable siding pillow, and a horizontal spindle arrangement. The square siding pillow moves horizontally within the enclosed square hole of the headstock. A high-precision CNC rotary table is located on the right side, and accessory magazines are positioned appropriately between the two columns, accommodating two headstocks.


Purpose

Primarily used in the machinery industry for heavy-duty cutting and rough and fine machining of various materials, including ferrous and nonferrous metals and steel castings, it can perform boring, milling, drilling, reaming, rigid tapping, annular grooving, and thread milling. A milling cutter can be mounted on the spindle end, enabling machining of workpiece cavities, inner cavity sides, inner cavity holes, and large end face seams. It features high rigidity, high precision, high torque, a wide speed range, high load capacity, multifunctionality, high transmission efficiency, stable and reliable operation, and excellent operability.
