Boring bar rotation and feed are fully gear-driven. Combined with the 2 HP drive motor, this ensures rapid, chatter-free cuts and extended longevity compared to belt-drive systems. Speed and feed rates have a wide range of adjustments to match the characteristics of engine block material and the size of the bores. Because of the convenient controls, the operator can keep close watch on the boring process and can easily make speed adjustments if necessary.


A special feature of the LB Series machines is their unusually long spindle travel which allows blocks to be bored with fewer interruptions to reposition the tooling.


Standard Tooling

Base castings are exceptionally heavy to eliminate any possibility of deflection, while the precision machined surfaces and excellent universal fixtures position work pieces securely during operation.
