Soraluce offers its KB-150-W series of T-type horizontal boring machines for multi-face machining of large workpieces weighing as much as 30,000 kg. The combination of linear guiding and hydrostatic systems provides high dynamics while the rigid structure and boring spindle design promotes long-term precision, the company says.
The machine’s cross axis and quill spindle offer high feed forces for increased stock removal. For precision and rigidity, all main machine elements are made of cast iron, and finite element methods are said to minimize vibration problems. A user-friendly configuration enables machine operation beside the work area, easing part setting and measuring operations, the company says. A full enclosure is also available.
Mounted on large, angular contact ball bearings and lubricated with an air-oil system, the 3,000-rpm, 47-hp quill spindle offers thermal stability with the assistance of a cooling system applied to the bearing, gearbox and spindle motor systems. According to the company, this stability, combined with a high power transmission, produces high stock removal capacity and feed force.
The 2,500 × 3,000-mm rotary table uses high-precision, low-friction bearing surfaces for smaller load capacities and hydrostatic bearings for larger load capacities, eliminating surface wear. The table rotates via a dual drive system using a large, external crown gear with helical gearing and a zero-backlash precision gearbox. The hydraulic clamping system allows for a maximum tangential clamping force of 140,000 Nm (103,244 foot-pounds).
