2003 HERMLE B300 VERTICAL MACHINING CENTERS

Technical Description

The 2003 Hermle B300 is a 5-axis vertical machining center manufactured by Berthold Hermle AG of Germany, a specialist in high-precision simultaneous 5-axis machining. The B 300 U employs a swiveling rotary table design—with a rotary table diameter of 11 inches—that provides full 5-axis simultaneous contouring capability for complex aerospace, medical, and mold-making components. The machine offers an X-axis travel of 31.5 inches, Y-axis travel of 23.6 inches, and Z-axis travel of 19.7 inches, accommodating a range of workpiece sizes within the 5-axis envelope. The high-speed spindle delivers up to 15,000 RPM with approximately 25.5 HP, enabling productive material removal in aluminum, steel, titanium, and Inconel. The Heidenhain iTNC 530 CNC control provides full simultaneous 5-axis contouring, high-speed machining cycles, and integrated tool management, with a conversational programming interface well-regarded for its ease of use and capability in complex 5-axis work. Hermle's characteristic trunnion-table architecture places the workpiece at the center of machine rotation, minimizing the axis moment arm and maximizing rigidity during simultaneous 5-axis cuts. The machine's robust cast-iron structure and precision spindle bearing system support the tight tolerances required for aerospace and precision die-mold applications. Weighing approximately 18,739 pounds, the B 300 U represents Hermle's commitment to combining high-precision machining capability with long-term mechanical stability.
