Line Boring LB20

The LB Series machines deliver superior accuracy and reliability for successful line boring.

Their base castings are exceptionally heavy to eliminate any possibility of deflection, while the precision machined surfaces and excellent universal fixtures position workpieces securely during operation. Boring bar rotation and feed are fully gear driven. This, combined with the 2 HP drive motor, insures rapid, chatter-free cuts and extended longevity compared with 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.
