A special purpose large lathe with two sets of headstock and tool post was designed exclusively to turn turbine discs. After finish turning one side of the disc using one headstock, the other headstock approaches, chucks and moves to its home position to turn the other side of the disc, where time consuming rechucking job is drastically reduced.

Precision finishing of Cylinder Liner Bore

A special purpose large lathe with a long square boring bar and a tool holder for fine finishing of cylinder liner bore.
