From a microscopic perspective, ultrasonic milling is a type of pulse milling. During a vibration cycle, the effective milling time of the tool is very short, with the tool separating from the workpiece and chips for more than 80% of the time. The intermittent contact between the tool and the workpiece, as well as the chips, reduces the friction on the tool, greatly reduces the heat generated, significantly reduces the milling force, avoids the "letting go" phenomenon in ordinary milling, and does not produce chip lumps. By using this type of ultrasonic milling, precision machining can be carried out on ordinary machine tools. The form and position tolerances such as roundness, cylindricity, flatness, parallelism, straightness, etc. are mainly determined by the accuracy of the machine tool spindle and guide rail, which can reach close to *, making it possible to replace grinding with turning, hinge with drilling, and grinding with milling. Compared with high-speed hard milling, it does not require high machine rigidity and does not damage the metallographic structure of the workpiece surface. In the precision machining of curved contour parts, CNC lathes, machining centers, etc. can be used for contour machining, which can save the high cost of purchasing CNC grinding machines. Ultrasonic turning is widely used in mechanical machining.

advantage

1. AdoptNon contact rotating ultrasonic knife handle,Brushless non-contact power transmission, high transmission efficiency.

2. The ultrasonic milling force is small, about 1/3-1/10 of the milling force of ordinary cutting tools.

3. Ultrasonic turning has high machining accuracy, which mainly depends on the precision of the machine tool used. The shape and position tolerances of the machined workpiece can almost approach the relevant precision of the machine tool.

4. The ultrasonic milling temperature is low, and the workpiece remains at room temperature.

5. No accumulation of debris, minimal deformation of the workpiece, and no burrs.

6. Ultrasonic milling has low surface roughness, which can approach the theoretical roughness value and reach Ra0.2 or below.

7. The "rigidity" of parts processed by ultrasound is equivalent to an increase in workpiece rigidity compared to ordinary milling.

8. The ultrasonic machining process is stable and can effectively eliminate chatter.

9. The cooling and lubrication effects of ultrasonic milling fluid are improved.

10. The durability of cutting tools has increased several times to tens of times.

11. The surface subjected to ultrasonic processing is in a state of compressive stress, which improves the fatigue, wear resistance, and corrosion resistance of the parts.

The surface of the workpiece after ultrasonic turning exhibits a rainbow effect.

application

Due to the many advantages of ultrasonic milling, it can be widely used for milling various difficult to machine materials in aviation, aerospace, military and other fields.
