The Tongtai MDV-551-5AX 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 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 positiong accuracy of +/-.00012″ and repeatability of .00004″.
Along with precision comes speed. Rapid traverse rates of 1575″/min in all axes reduce non-cutting times. Powerful servo motors are direct coupled to the large diameter ballscrews. The Z axis produces 2,640 lbs of thrust. A precision, powerful, 30HP, 12,000 RPM integral spindle provides both low end torque and high speed finishing ability. The spindle is available in both 40 taper or HSK-63A. 18,000 and 24,000 RPM spindles are also available.
At the heart of the machine is the Japanese built trunnion table. Utilizing and 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 or +/- 3 arc seconds and repeatability of 1 arc second. A rotary union to supply hydraulics for fixtures is standard!
Excellent ergonomics also make this machine easy on the operator. The spindle center to the front of the machine is only 17.5″ for easy reach to both the tool and the table. The table height is only 43.3″ from the floor.
The standard 30 tool ATC is high speed, changing tools in only 0.9 seconds!
An impressive list of standard features includes a heavy duty 30 tool TC that is mounted to the machine for easy maintenance, a chip removal system consisting a coolant jet wash that forces chips into a caterpillar type conveyor at the right side of the machine, a high volume 200 gallon coolant system, and a full machine enclosure (including the top) to contain chips and coolant. Your choice of Fanuc controls provides the ideal combination for all types of application. The Fanuc 18iM-B is standard for most job shop and high speed 3-D applications, using the machine in a 4 + 1 axis mode where the 5th axis is positioning only. The Fanuc 18iM-B5 is available for applications requiring simultaneous 5 axis contouring. Both controls feature the new Alpha I servo system with 1,000,000 pulse encoders. Heidenhain TNC-i530 is also available.
