1. Heavy duty lathes adopt 1100mm wide rectangular induction hardened and ground bed guide-ways;
2. Excellent stability, high rigidity, and with maximun bearing of 12 tons between centers;
3. The main spindle is precision roller bearings, 3-point supporting structure;
4. Rotating tailstock quill structure to minimize friction and heat generation;
5. Suitable for various turning works, such as turning of external and internal cylindrical surfaces, end faces, turning of mertic or inch threads, modular threads and diametrical pitch threads, etc.;
6. Motorized short taper turning could be done by the top slide independently, and long taper motorized turning could be done by top slide combined with longitudinal feed.
