1993 YANG MV5A VERTICAL MACHINING CENTERS

Technical Description

The 1993 YANG MV5A is a 3-axis vertical machining center manufactured by Yang Iron Works of Taiwan, designed for heavy-duty milling of large workpieces including dies, molds, and structural components. Built on a Meehanite cast iron frame, the MV5A features a substantial 70.9 x 32.3 inch working table and generous axis travels suitable for large-envelope work. The machine incorporates a high-torque BT50 spindle with a maximum speed of 3,500 RPM, optimized for heavy-material removal in steel and cast iron rather than high-speed aluminum finishing. A 30-station automatic tool changer enables complex multi-operation setups without manual intervention. The machine’s robust column and saddle construction minimize deflection under aggressive cutting loads, and the counterbalanced spindle head contributes to smooth, vibration-damped Z-axis motion. Chip management and fully enclosed guarding are standard features to support production-floor cleanliness. The YANG MV5A was well regarded in its era for its rigidity and build quality, making it competitive with European and Japanese machines in the large-frame VMC segment. Its CNC control, typically a Fanuc derivative, provides standard conversational programming and DNC capability. Despite its age, well-maintained units remain productive for toolroom, prototype, and low-volume production applications requiring large part capacity and heavy cuts.
