The new 100 kHz ultrasonic system UTS2 from son-x GmbH enables direct ultra-precision machining of steel with no geometric restrictions. The UTS2 operates at a unique frequency of 100 kHz, so that maximum efficiency is combined with precision. With the innovative process, steel alloys and some types of glass can be manufactured with the highest quality (Ra <3nm, PV <200 µm). The classic application is the optical mold.
The UTS2 works with the principle of ultrasonic-assisted machining. In this case, the diamond tool is set into a linear oscillatory motion in the cutting direction at a frequency of 100 000 Hz.
The high-frequency vibration of the tool causes a repeated separation of the cutting tool and the material. The contact time between diamond and material is only about 2 µs per cycle and overall 20% of the total processing time. The cyclical tool contact is repeated 100 000 times per second.
A large number of positive effects are achieved using this technology, e.g. improved cooling conditions and the interception of chemical wear reactions. This significantly reduces the wear of the diamond and enables the direct cutting of stainless steel.
