Following the success of the UltraTEC A25, A100 and B10 ultrasonic deburring systems, Vollmer UK is launching the new A25S. UltraTEC is part of the Vollmer Group and has won a string of awards for its patented ultrasonic deburring technology that only uses water.

Formed in 2019, UltraTEC offers proprietary technology that utilises an oscillating ultrasonic horn to generate soundwaves and cavitation for cleaning and deburring external and internal edges reliably. The environmentally friendly solution uses water to provide sharp-edged burr-free parts that are often impossible to process via alternative methods.

Suitable for small to medium-sized components, the UltraTEC ultrasonic A25S creates a formation and dissolution/implosion of bubbles in the water that releases intense energy. This energy arrives courtesy of ultra-high oscillation at 20 kHz with an oscillation width of ±80-120 µm, which far exceeds the amplitude of ultrasonic cleaning, cutting and welding technologies.

The new A25S takes the innovation of UltraTEC’s previous models and offers more rigidity, vibration dampening and thermal stability with a welded steel machine base filled with mineral concrete. This base creates a more robust platform, ensuring enhanced machine kinematics, component quality and repeatability.

Improved stiffness and a heavier base are the foundation blocks for a welded steel machine frame that replaces the aluminium version on previous models. The new steel frame also improves operator access and ergonomics, while creating a streamlined and futuristic machine appearance. This structure also incorporates a new PE500 confetti structure insulation that supersedes the previous machine insulation to yield better noise insulation and extend machine life with its water-resistant characteristics.

Hydraulic System Products (HSP) contacted MecWash to upgrade its component cleaning to meet increasing demand and the strict cleanliness requirements of clients. With high standards required from customers in the OEM construction industry, the quality of the wash and dry process was essential to the success of the business.

Alan Atkinson, sales manager at MecWash, says: “We carried out extensive research at HSP to understand the application and the contaminants involved in their hydraulic products. Delivering precision engineered parts manufactured to the highest specifications requires rigorous cleaning of the components.”

The MecWash MWX300 was selected as the most effective machine for HSP’s application, with full ultrasonic cleaning functionality. Ultrasonic wash and rinse capabilities transmit high-frequency sound waves through the wash solution, which destabilises the contamination and facilitates fast and economical cleaning with high process quality.

“The processes that follow include a flood and spray rinse, hot air dry, vacuum dry and ambient air cooling, providing an extremely thorough cleaning and drying process, and a fantastic finish,” says Atkinson.

Stephen Westwood, general manager at HSP, adds: “We considered several manufacturers, but through trials and proving out of the MecWash MWX300’s capabilities, we were impressed with the machine’s excellent cleaning results. This improvement has enabled us to meet or exceed our OEM client’s stringent cleanliness standards. We are delighted with our new machine and value its ability to clean and achieve our customers stringent cleanliness standards.”

Precision and process reliability have characterised automotive engineering for many decades. With the establishment of e-mobility, however, these demands are increasing once again, because many e-motor components require surface finish in the micron range so that no loud running noises occur on gear components.

In this context, the technology of Emag is drawing the attention of many production engineers. Among other things, Emag develops high-performance solutions for gear grinding that offer short chip-to-chip times, intelligent axis concepts, thermal and mechanical stability, and a high degree of user-friendliness.

The company’s solutions for the field of gear profile grinding include the G250 and G160. The G160 is for components up to module three and with a maximum OD of 160 mm (250 mm G250). In this field of application, Emag says it is the fastest machine on the market, made possible by two parallel workpiece tables that move alternately at high speed to the grinding wheel. Thus, while one component is undergoing machining, the internal loading robot inserts a blank into the other spindle or unloads the finished component beforehand.

Notably, the G160 does not have a tangential axis, but instead the existing Y and Z axes generate a ‘virtual’ tangential axis through simultaneous movement. As a result, the distance between the A axis and the tool contact point is very small, which in turn prevents so-called ‘ghost frequencies’ on the part surface.

The possibilities this approach opens up for e-mobility are shown, for example, by an ‘intermediate shaft’ with 21 teeth and a normal module, where manufacturers using the G1160 can achieve a floor-to-floor time of only 33 seconds (including entanglement compensation and proportional dressing time) and a grinding time of just 25 seconds.
