1. What is the Ultrasonic Impact Hammer Equipment used for?
It is an ultrasonic impact treatment (UIT) machine designed to relieve residual stress, improve surface properties, and perform chamfering/surface treatment on steel and other metal components.
2. How does ultrasonic impact treatment work?
The device delivers high-frequency (20 kHz) ultrasonic impacts via tungsten needles to the metal surface, producing controlled plastic deformation that induces beneficial compressive residual stresses and improves fatigue resistance.
3. Which materials can be treated with this machine?
It is suitable for steel and most metal components. Compatibility with coated or delicate surfaces should be verified and tested before full-scale use.
4. What are the main specifications of the machine?
Key specs: machine type — chamfering machine; weight — 16 kg; brand — DOWELL; ultrasonic frequency — 20 kHz; ultrasonic timer — 0.01–9.99 s; needle size — 3 mm; needle material — tungsten steel; number of needles — 4; digital ultrasonic generator with automatic frequency tracking; power amplitude adjustable 50%–100%.
5. What does the ultrasonic timer range (0.01–9.99 seconds) control?
The timer controls the duration of each ultrasonic impact pulse applied to the surface, allowing precise control of treatment time per impact cycle to achieve desired stress-relief effects.
6. What is automatic frequency tracking and why is it important?
Automatic frequency tracking enables the generator to continuously adjust to the resonant frequency of the tool and load, ensuring stable, efficient operation and consistent impact performance without manual tuning.
7. What is the needle configuration and material?
The unit uses four tungsten steel needles, each 3 mm in size. Tungsten steel provides high hardness and wear resistance for consistent impact performance.
8. How portable is the machine?
At 16 kg and a compact design, the machine is lightweight and easy to handle for transport and use across job sites, though safe handling practices should be followed.
9. Can this machine replace thermal stress-relief or shot peening?
Ultrasonic impact treatment is an alternative to thermal stress relief and shot peening in many applications. UIT provides localized compressive stresses with minimal heat and distortion and can complement or replace other methods depending on the part, specifications, and required outcomes. Evaluate per application and applicable standards.
10. What safety precautions should operators take?
Use appropriate PPE (safety glasses, hearing protection, gloves), secure the workpiece, avoid direct contact with the working tip during operation, ensure proper grounding of equipment, and follow manufacturer safety instructions and local regulations.
11. How should the machine and needles be maintained?
Regularly clean the tool and generator, inspect needles for wear or deformation, replace worn needles promptly, verify proper operation of automatic frequency tracking, and follow the manufacturer's maintenance schedule and recommendations.
12. How often should needles be replaced?
Replacement frequency depends on usage, material treated, and impact conditions. Inspect needles before and after shifts; replace them when there is noticeable wear, deformation, or reduced performance to maintain consistent results.
13. Is this equipment environmentally friendly?
Yes — the machine is described as eco-friendly: ultrasonic impact treatment is low-emission, typically consumes less energy than thermal processes, and causes minimal material waste or heat-related distortion.
14. Where can I get technical support, consumables, or warranty information?
For technical support, spare needles/consumables, and warranty details, contact the supplier or DOWELL directly. They can provide service options, recommended spare parts, and official documentation.
