Rotary-type Ultrasonic-assisted Machining Center



Tongtai's brand new iVU-5 is a rotary-type ultrasonic-assisted machining center that operates as a dual function vertical machining center combined with rotary ultrasonic-assisted machining of advanced materials.

Typical applications for this system include microhole drilling and machining of glass, sapphire, silicon carbide, quartz, ceramic, hardened steel, high nickel alloys and non-ferrous materials. Any material that is softer than the cutting tool can be ultrasonic-assisted. Rotary ultrasonic machining combines high-speed spindle rotation with high frequency vertical vibration of the cutting tool. The diamond tool impacts the material with high contact speed, reducing cutting force and producing ultra-fine finishes while improving cutting efficiency three to five times faster than conventional machining, the company reported.

The Tongtai iVU offers X, Y, Z-axes travels of 500 mm (20") x 400 mm (15.7") x 350 mm (13.8"). It features a Meehanite cast iron frame and roller type linear slideways for rigidity and fast, precise movement. The 25 mm (1") diameter ball screws are class 3 with a double nut pre-loaded design allowing a standard rapid traverse rate of 1,890 IPM in all axes with acceleration of 1.2G. The iVU-5 is equipped with a 30-tool arm type automatic tool changing (ATC) system. The fast, high-speed arm type ATC changes tools in .8 seconds and 1.3 seconds chip-to-chip time. The 3 HP, 20,000 RPM direct drive spindle comes standard in dual contact BIG Plus 30 taper (BBT-30). A spindle chiller is standard.

For ultrasonic operation, the Tongtai iVU-5 comes standard with automatic frequency search and lock via M-codes. The auto tuning range is from 15-45 kHz. Amplitude range is 1 - 10 microns. The machine has a wide range of standard features for successful ultrasonic machining and long machine life.

The 3-axis machine is equipped with Siemens 828D control with 10.4" TFT with ShopMill and Advanced Surface. The 5-axis version is equipped with Siemens 840D control with 17" IPC, the Sinumerik MDynamics Technology package for 5-axis milling and ShopMill.
