Bost Turnmill lathe

Features
Maximum dynamic of the machine.
Oversized structure.
High chip removal rate by means of
high static bending and torsional
stiffness.
Optimized stiffness of the machine by
FEM Finite Element Method system.

This table drive system reduces transmission elements,
achieving a higher accuracy and a belter surface quality,
