ACCUT TK6913 HORIZONTAL BORING MILLS

Technical Description

The ACCUT TK6913 is a robust horizontal boring mill designed for high-precision machining, featuring a main boring spindle diameter of 130 mm (5.12 inches) with an ISO 50 taper. It is powered by a 46.9 HP motor, achieving spindle speeds up to 2,000 RPM (or 0.5–1500 r/min depending on source data). The machine offers extensive travel capabilities, including an X-horizontal column travel of 472.44 inches and a Y-vertical head travel of 78.74 inches. The Z-spindle travel is 70.87 inches, complemented by a 700 mm Z-axis ram and a 1000 mm W-axis boring bar travel, totaling 1800 mm. The TK6913 is equipped with a large 2000 x 2000 mm table capable of handling loads up to 35,000 kg. Precision is ensured by a positioning accuracy of 0.01 mm across the X, Y, and Z axes, utilizing features like hydrostatic guideways on major axes and a backlash-free double pinion ballscrew drive. The machine is controlled via a highly flexible CNC system, with options including Siemens (802D sl / 840 sl), Fanuc (0i), or FAGOR. The machine structure is heavy-duty cast iron, weighing approximately 35 tons.
