New Tongtai T51-USA Ultrasonic Machining Center


Tongtai Seiki USA Inc.


Tongtai has released a new ultrasonic machining center—the T51-USA, which can machine hard and brittle materials.

Tongtai has developed a non-contact electrical material elimination supply with ultrasonic machining technologies, according to the company. The advantage of electricity without contact is eliminating oxidation so there is no chance of unstable machining and electric leakage, according to the company. With the ultrasonic machining device, the machining efficiency of the original spindle has been improved from three to five times, the Valley Cottage, N.Y.-based company reports. The material eligible for ultrasonic machining includes aluminum alloy, hardened steel, glass and ceramic materials.

The T51-USA adopts the 0i-MD controller with spindle speeds up to 20,000 rpm. Those are combined with a spindle cooling system that uses recycled coolant to avoid thermal distortion during long-term machining. Also, the direct-drive type spindle connects with the motor by coupling to ensure the best output in horsepower and torque.

Three axes feeding devices adopt FANUC “?” series servo motor and precision level ballscrews and linear guide ways. This allows the rapid traverse to achieve 1890"/min. Moreover, the increase in speed acceleration and deceleration improves machining efficiency, the company reports.
