The KMTC TK6916 is a robust Horizontal Boring Mill controlled by a CNC system (Siemens/Fanuc options), designed for large-scale precision machining. Key specifications include a large 6.28-inch (Ф160 mm) spindle bore diameter with an ISO 50 (BT50) taper, capable of a maximum turning speed of 1,500 RPM. This machine offers substantial travel capacity, with the column longitudinal travel (X-axis) reaching 313.00 inches (8000 mm) and the boring head vertical travel (Y-axis) up to 116.93 inches (4500 mm). The boring spindle (W-axis) and ram (Z-axis) each have 1200 mm of travel, combining for a total Z/W travel of 2400 mm, with the ram section measuring 480 x 520 mm. Feedrates for the ram and boring spindle range from 1 to 4000 mm/min, while travel speeds for the X and Y axes go up to 6000 mm/min. Positioning accuracy is maintained with linear scales, achieving ±0.025/1000 mm on the X and Y axes. The machine delivers a maximum torque of 10000 N·m at the boring head and is powered by a 51 kW main servo motor. Furthermore, it boasts a substantial weight capacity of 40,000 kg (40 tons) on the rotary table, making it suitable for machining very heavy workpieces.
