TOS WHN-13/4A HORIZONTAL BORING MILL

The TOS WHN-13/4A Horizontal Boring Mill is a robust machine designed for precise machining of large, heavy workpieces, commonly utilized in sectors like energy and heavy machinery. Key technical features include a 5.11-inch (130 mm) spindle with an ISO 50 taper and a speed range up to 4,000 rpm, powered by an approximately 34–37 kW main motor. The machine features an expansive rotary table, dimensioned at 1800 x 1800 mm, capable of handling loads up to 12 tons. Travel specifications include 86.50 inches (2000 – 3500 mm) of longitudinal table travel (X-axis) and 94.40 inches (approximately 2,500 mm) of vertical head travel (Y-axis). The machine utilizes a rigid frame structure to minimize vibration and ensure accuracy. For CNC versions, it often incorporates HEIDENHAIN control systems (such as iTNC 530), a B-axis with 360,000 positions, and an extending ram, allowing the spindle to reach beyond the center of the table for comprehensive multi-sided machining.
