Short description

• Series 69 CNC floor-type boring mills (TK69 series) designed for heavy workpieces and integrated milling/boring operations.
• Guide options: roller-sliding hybrid; high-speed imported roller linear guides; closed hydrostatic guide structure with multi-pump system (structural variants available).
• CNC rotary table: load capacity 20 t–200 t; table sizes from 2 m × 2 m to 5 m × 10 m; supports arbitrary indexing and simultaneous multi-axis linking.
• Available tool magazine capacities and spindle diameters to match machining needs (model-dependent).
