Status: during general overhaul.

The PORĘBA TR series lathe is a universal machine tool intended for both roughing and finishing operations. It is particularly suitable for machining shafts as well as heavy, large-size workpieces.
The offered machine is currently undergoing a general overhaul – the last photo presents its current stage of refurbishment.
