The Winona Van Norman LB Series Line Boring Machines are engineered to deliver exceptional accuracy, rigidity, and reliability for precision line boring of engine blocks and other critical components. Designed for professional engine rebuilding, remanufacturing, and industrial machine shops, the LB Series restores main bearing bores to exact factory specifications, ensuring proper crankshaft alignment, bearing fitment, and long-lasting engine performance. Its heavy-duty construction and precision engineering provide the stability required to consistently produce accurate, repeatable results across a wide range of automotive, diesel, marine, and industrial applications.

Built for maximum performance, the LB Series features exceptionally heavy cast iron base castings that virtually eliminate deflection during machining, while precision-machined surfaces and versatile universal fixtures securely position workpieces for superior accuracy. The fully gear-driven boring bar rotation and feed system, powered by a robust 2 HP drive motor, delivers smooth, chatter-free cutting with greater durability and lower maintenance than conventional belt-driven designs. Variable speed and feed adjustments allow operators to optimize machining parameters for different engine block materials and bore sizes, while conveniently located controls provide precise operation and continuous monitoring throughout the boring process.

Designed to maximize productivity, the Winona Van Norman LB Series features an extended spindle travel that allows more bores to be machined before repositioning the tooling, reducing setup time and increasing efficiency. Combining rugged construction, precision engineering, and dependable long-term performance, the LB Series delivers the accuracy, repeatability, and reliability professional machine shops rely on for superior line boring results every day.
