The Winona Van Norman LB Series Line Boring Machines are engineered to provide unmatched precision, rigidity, and reliability for restoring main bearing bores to factory specifications. Designed for professional engine rebuilding, remanufacturing, and industrial machine shops, the LB Series delivers the accuracy required to ensure proper crankshaft alignment, bearing fit, and overall engine performance. Its heavy-duty construction and precision machining capabilities make it the ideal solution for automotive, diesel, marine, and industrial engine applications where tight tolerances are essential.

Built for superior machining performance, the LB Series features exceptionally heavy cast iron base castings that virtually eliminate deflection during operation, ensuring consistent accuracy throughout every boring cycle. Precision-machined surfaces and versatile universal fixtures securely position engine blocks for maximum stability, while the fully gear-driven boring bar rotation and feed system, powered by a robust 2 HP motor, provides smooth, chatter-free cutting and greater long-term durability than conventional belt-driven machines. Variable speed and feed controls allow operators to optimize machining parameters for different engine materials and bore sizes, giving complete control over every operation.

Designed to maximize productivity, the Winona Van Norman LB Series incorporates an extended spindle travel that allows multiple bores to be machined with fewer interruptions for tooling repositioning, reducing setup time and increasing shop efficiency. Combining rugged construction, precision engineering, and dependable long-term performance, the LB Series delivers the repeatable accuracy, reliability, and productivity professional machine shops rely on for high-quality line boring results every day.
