Gundfrilling/Milling System

TBT Division/Nagel Precision Inc. (Ann Arbor, MI) has introduced the Gundrilling/Milling-Center VARIOFLEX MD 30.

TBT Division/Nagel Precision Inc. (Ann Arbor, MI) has introduced the Gundrilling/Milling-Center VARIOFLEX MD 30. Specifically designed for the tool and mold industry, the center features a large working range and highest machine rigidity in all working directions. It used a rocking lever system which TBT has developed over the last year. The machine is the world’s first gundrilling machine that allows drilling of compound-angles in only one fixation. With this unique concept, moldmakers can significantly reduce their set-up time and operational cost. The machine combines both gundrilling and deep hole drilling with conventional machining (milling, counter boring and threading). With its capacity to drill diameters over two inches, the machine is ideal for machining even the largest molds. Machine capabilities include compound drilling of angles, combination of gundrilling and conventional machining in one axis, parallel-kinematics for optimal flexibility and accuracy and reduction of positioning times, double-sided bearings for the milling spindle for increased rigidity, drill spindle can reach virtually any position on a mold, allowing true 3-D machining, and automatic changeover between gundrilling and conventional machining is possible.
