Horizontal Boring Machine Handles Large Workpieces with Thermal Stability

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).
