Specification :

This series heavy duty lathes adopt 1.100MM wide rectangular induction hardened and ground bed guide ways , so of excellent stability, high rigidity, and with maximum bearing of 16 tons between centers. The main spindle is of precision roller bearings 3-point supporting structure. Saddle guide ways with Teflon belt coated .Rotating tailstock quill structure to minimize friction and heat generation.

These machines are suitable for various turning works, such as turning of external and internal cylindrical surfaces, end faces, and turning of metric or inch threads , modular threads and diametrical pitch threads.etc. Motorized short taper turning could be done by the top slide independently, and long taper’ s motorized turning could be done by top slide combined with longitudinal feed further more, these machines can also carry out drilling, trepanning and boring processes.etc.
