Introduction:
Ultrasonic vibration cutting is a special cutting technology that makes the tool vibrate at a high speed in the cutting direction at a frequency of 20-40KHz. Ultrasonic vibration cutting is a kind of pulse cutting from a microscopic perspective. In a vibration cycle, the effective cutting time of the tool is very short. The tool is completely separated from the workpiece chip during most of the time in a vibration cycle, and the tool is in intermittent contact with the workpiece chip. , The cutting heat is greatly reduced, and there is no "giving knife" phenomenon during ordinary cutting.
With this kind of vibration cutting, precision machining can be performed on ordinary machine tools. The form and position tolerances such as roundness, cylindricity, flatness, parallelism, and straightness mainly depend on the accuracy of the machine tool spindle and guide rails, and can reach a maximum of zero errors. It makes it possible to replace grinding with a car, replacing hinge with a drill, and grinding with a milling. Compared with high-speed hard cutting, it does not require excessive machine rigidity and does not damage the surface structure of the workpiece. In the finishing of curved contour parts, it can be contoured with the help of CNC lathes, machining centers, etc., which can save expensive CNC grinding machines Acquisition costs. Ultrasonic vibration cutting is used for the finishing of various parts that are difficult to grind and require high surface quality and accuracy. It has great advantages. The ultrasonic vibration cutting device is composed of an ultrasonic generator, a transducer, a horn, and a cutter. The high-frequency electrical signals emitted by the ultrasonic generator are converted into high-frequency mechanical vibration by the transducer, and the horn The amplitude of the vibration is amplified and applied to the prop. Generally, the component composed of the transducer and the horn is called an acoustic vibratior.
Application:
1. Processing of difficult-to-cut materials: stainless steel, hardened steel, high-speed steel, titanium alloy, high-temperature alloy, cold-hardened cast iron, and non-metal materials such as ceramics, glass, stone, etc., which are difficult to process due to mechanical, physical, and chemical characteristics, such as Using ultrasonic vibration cutting can make it easier.
2. Cutting of difficult-to-machine parts: such as slender shaft parts that are easy to bend and deform, small-diameter deep holes, thin-wall parts, thin-disk parts and small-diameter precision threads, as well as complex shapes, high machining accuracy and surface quality requirements Components.
3. High precision, high surface quality workpiece cutting.
4. Difficult chip removal and chip breaking.
Fourth, the application of ultrasonic vibration chip: widely used in aviation, aerospace, military and other fields.
