Since the founding of the company, ultrasonic tooling systems have been at the core of our competence. Building on ultrasonic assisted tooling systems, such as the cutting-edge UTS2, we enable direct diamond turning of stainless steel. Moreover, the 100 kHz ultrasonic system UTS2 from son-x has been continuously improved since its inception, making it the most successful and technologically advanced system of its kind. In addition, other products based on ultrasonic assistance have been established, such as a rotating ultrasonic system for grinding and milling. We offer our expertise to develop and commercialize ultrasonic systems tailored to specific demands.


The Ultrasonic Tooling System

Ultrasonic assisted tooling systems, such as the 100 kHz ultrasonic system UTS2 from son-x, enable direct ultra-precision machining of stainless steel with no geometric restrictions. Achieving a surface quality Ra of around 1 nm and a dimensional accuracy PV of 100 nm is feasible. The UTS2 operates at a unique frequency of 100 kHz, combining maximum efficiency with precision. With this innovative process, steel alloys, invar, and some types of glass can be cut directly using single crystal diamond tools. The classic application lies in optical mould manufacturing for injection or glass moulding.

Spindle System

Processing with ultrasonic assistance offers outstanding advantages in grinding, milling, and drilling of difficult-to-process materials (glass, ceramic, composites…). To achieve this, son-x offers complete spindle systems, including ultrasonic tool holders, designed to enhance existing production environments. The ultrasonic vibration is realized with specially developed ultrasonic actuators, tailored for respective machining tasks, thereby boosting productivity and quality.

Amplitude +-10 µm

Applications Ceramics, CFRP

Spindle Speed 30.000 rpm or higher

Tool interface HSK or other

System Engineering

Ultrasonic assistance is a promising approach to enhance the performance of machining processes. Like in diamond turning or grinding of difficult-to-cut materials, in many cases it is the superposition by ultrasonic motion which enables the manufacturing process. son-x offers custom made solutions for ultrasonic machining applications for all fields of engineering. Starting with a detailed analysis of the problem to be solved, son-x covers the entire chain from the design to ready-to-use prototype systems and the commercial production of them.
