The new Tongtai HS-22 high-speed, high-precision, slant-bed turning center, distributed by Absolute Machine Tools, can be equipped with an optional automatic part loading/unloading system. It functions from the end of the machine rather than a gantry system that operates from the top of the machine. Swap time is 4.8 sec., and a 14-pallet work stocker enables unattended machining.
The turning center offers a swing-over-bed diameter and standard turning diameter of 8.66 in. Maximum cross-travel is 6.1 in. (X axis), and maximum longitudinal travel is 8.66 in. (Z axis). Maximum turning length is 7.87 in.
Precision box ways and large servomotors provide a rigid, compact structure. The headstock, tailstock, turret, and saddle all are mounted on a one-piece, 30-degree slant bed to help ensure precision and thermal stability. The coolant tank is separate from the machine base to prevent heat transfer from the coolant to the machine casting.
