Soraluce’s KB-150-WR T-type horizontal boring machine provides high efficiency and durability for multi-face machining of large workpieces. The machines cast iron elements and linear roller guideways combined with a hydrostatic damping system provides high dynamics for improved performance. Three complete cooling systems for the bearings, gearbox and spindle motor provide high thermal stability to the machine’s 150-mm-diameter quill. The rigid, 3,000-rpm quill spindle is mounted with large angular contact bearings lubricated with an air-oil system. The spindle design is matched to an oversized ram to enable efficient machining in extended reach applications. The machine offers 787-ipm rapid rates, high axis feed forces, a 5.9" quill with 31.5" of travel, and a large ram with 40" of stroke.

A variety of rotary tables are available to meet specific part weight requirements. These tables rotate on high-precision bearing and low-friction surfaces for smaller load capacities and hydrostatic bearings for larger load capacities. The dual-drive system uses a large external crown gear with a helical gearing/zero-backlash precision gearbox for table rotation. A hydraulic clamping system provides for a maximum tangential clamping force of 140,000 Nm (103,200 foot-pounds).

    Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
