The four-machine Tongtai MDV and GT Series of high speed, high accuracy 5-axis trunnion table machining centers is engineered for complex, precise machining of mold, die, aerospace and medical parts. The machines have heavy Meehanite castings, roller-type linear guideways in linear axes, and zero-backlash roller gear mechanisms in tilt and rotary axes to maximize rigidity and precision. Large diameter double-anchored and pre-tensioned ballscrews with least increment input of 0.0001mm/ 0.00001″ produce positioning accuracy of +/- 0.003mm (0.00012″) and repeatability of 0.0025 mm (0.0001″) with scales.
