TONGTAI GT-630 (5 Axis Machining Center)

The Tongtai GT-630 is a high speed, high accuracy 5 axis trunnion table machining center. This machine delivers outstanding overall performance and value for the complex machining of mold, die, aerospace, and medical parts. The machine features strength from a heavy meehanite casting. Precision comes from large roller type linear guideways in the linear axes and a unique, no backlash direct drive torque motor system in the 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). 40,000 lb. machine weight ensure stability and rigidity.

At the heart of the machine is the direct drive torque motor trunnion table. The tilt / rotary table utilizes high torque, high speed, direct drive torque motors and hydraulic clamping. High speed rotation of 50 RPM on the rotary axis and 30 RPM in the tilt axis reduces cycle time. Since this is torque motor system with NO BACKLASH, the table delivers outstanding accuracy of +/- 5 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!
