The Winona Van Norman LB Series Line Boring Machines are built to deliver exceptional accuracy, rigidity, and dependability for precision line boring applications. Engineered for professional engine rebuilding, remanufacturing, and high-production machine shops, the LB Series restores main bearing bores to precise factory specifications, ensuring proper crankshaft alignment, bearing fit, and long-term engine reliability. Designed to handle automotive, diesel, marine, and industrial engine blocks, these machines provide the precision required for today’s demanding machining applications.

Constructed with exceptionally heavy cast iron base castings, the LB Series virtually eliminates machine deflection for superior accuracy throughout the boring process. Precision-machined surfaces and versatile universal fixtures securely position engine blocks, while the fully gear-driven boring bar rotation and feed system, powered by a robust 2 HP motor, delivers smooth, chatter-free cutting with greater durability than conventional belt-driven designs. Variable speed and feed controls allow operators to optimize machining performance for different block materials and bore sizes, while conveniently located controls provide complete visibility and easy adjustments during operation.

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 shop efficiency. Combining heavy-duty construction, precision engineering, and reliable long-term performance, the LB Series provides the accuracy, repeatability, and durability professional machine shops rely on to consistently produce superior line boring results.
