TONGTAI MDV551-5AXII
Tongtais MDV and GT Series are high speed, high accuracy 5-Axis trunnion table machining centers. This machine delivers outstanding overall performance and value for the complex machining of mold, die, aerospace, and medical parts. The machines feature strength from a heavy meehanite casting. Precision comes from roller type linear guideways in the linear axes and a unique, no backlash roller gear mechanism in tilt and rotary axes. Large diameter double anchored and pre-tensioned ballscrews along with least increment input of .0001mm/ .00001 allows positioning accuracy of +/-.00012 and repeatability of .0001 (with scales).
At the heart of the machines is the Japanese built trunnion table. Utilizing the unique, patented roller gear drive (as opposed to a worm gear or direct drive), high torque, high speed, and superior clamping capability is accomplished. In fact, no auxiliary clamping system is required as the roller gear drive acts as a gear reducer, simplifying design and eliminating hydraulics to clamp the table.
High speed rotation of 360 degrees in 1.8 seconds on the rotary axis and 120 degrees in 1.8 seconds in the tilt axis reduces cycle time. Since this is a preloaded system with NO BACKLASH, the roller gear drive delivers outstanding accuracy of +/- 7 arc seconds and repeatability of only +/- 2 arc seconds utilizing the standard high accuracy rotary scales. A rotary union to supply hydraulics for fixtures is standard!
