BOTOU GIANT TK6916 HORIZONTAL BORING MILLS

Technical Description

The BOTOU GIANT TK6916 is a robust horizontal boring mill designed for high-precision machining. Key technical specifications include a spindle bore diameter of 160 mm (5.12 inches) with an ISO 50 (BT50) taper, capable of a maximum turning speed of 1500 rpm and delivering a maximum torque of 10000 N·m at the boring head. The machine features extensive travel capabilities, including a 8000 mm column longitudinal travel (X-axis) and a 4500 mm boring head vertical travel (Y-axis), complemented by a total spindle and ram travel of 2400 mm (W and Z axes, each 1200 mm). The feedrates for the ram and boring spindle range from 1 to 4000 mm/min, while the X and Y axis travel speeds reach up to 6000 mm/min. Positioning accuracy with linear scales is tight, specified at ±0.025/1000 mm for the X and Y axes, and ±0.03/1000 mm for the Z and W axes. Repetitive positioning accuracy is rated at ±0.015/1000 mm for all axes. Driven by a 51 kW servo main motor and controlled by a CNC system (Siemens/Fanuc), the machine is built to handle heavy-duty tasks, boasting a maximum table load of 40,000 kg and an approximate total weight of 65 tons.
