Available from Absolute Machine Tools, Tongtai’s TT51-USA ultrasonic machining center is designed to machine aluminum alloy, hardened steel, glass and ceramic materials. According to the company, the machine features a user-friendly operator interface as well as increased precision.
A non-contact electrical material elimination supply with ultrasonic machining technologies is available for hard and brittle materials. According to the company, a benefit of electricity without contact is eliminating oxidation so there is no chance of unstable machining and electric leakage. With the ultrasonic machining device, the machining efficiency of the original spindle has been improved from three to five times, the company says.
The T51-USA adopts the 0i-MD controller with spindle speeds ranging to 20,000 rpm. Those are combined with a spindle cooling system that uses recycled coolant to avoid thermal distortion during long-term machining. Furthermore, the direct-drive type spindle connects with the motor by coupling to ensure maximum output in horsepower and torque.
Three axes feeding devices adopt FANUC “α” series servo motor and precision level ballscrews and linear guide ways. This enables the rapid traverse to achieve 1,890 ipm. Moreover, the increase in speed acceleration and deceleration improves machining efficiency.
