A large, robust machine tool configuration designed for heavy-duty material removal and precise machining of sizable workpieces. This configuration typically features a stationary workpiece mounted on a rotary table, while the cutting tool, held by a vertically oriented spindle, moves along multiple axes. A common application involves enlarging existing holes with high accuracy, or creating precisely sized bores in large castings or forgings.
The inherent rigidity and power of this machine configuration makes it invaluable for industries requiring high precision and efficient material removal in large-scale components. Sectors like aerospace, energy, and heavy equipment manufacturing benefit from its ability to produce complex parts with tight tolerances. Its development represents a significant advancement in machining capabilities, enabling the creation of larger, more intricate, and more precise components than previously possible with conventional milling or turning methods. This has had a profound impact on manufacturing efficiency and the overall advancement of engineered systems.
