A Brief Introduction To Ultrasonic Assisted Machining

Vibration cutting is an advanced manufacturing technology developed in the 1960s. It applies a high-frequency vibration on a conventional cutting tool to make intermittent contact between the tool and the workpiece, thus making a fundamental change in the traditional cutting mode. This change solves the problems inherent in the conventional cutting process, such as vibration during cutting and thermal deformation of the cutting, thereby obtaining an excellent cutting effect.

Ultrasonic vibration cutting can improve the zero-ultrasonic vibration cutting technology. It is a new type of technology that combines the ultrasonic vibration force regularly on the tool to make the tool periodically cut and leave the workpiece. It is a new type combining ultrasonic technology and traditional cutting technology. Cutting technology.

Workpiece surface quality and machining accuracy, can extend tool life, improve cutting efficiency, expand the application range of cutting, can be widely used in car, planing, milling, grinding, thread processing and stainless steel, hardened steel, high speed steel, titanium alloy , high-temperature alloys, chilled cast iron and non-metallic materials such as ceramics, glass, stone, etc.

Ultrasonic vibration cutting principle

Ultrasonic vibration cutting is a special cutting technology that allows the tool to vibrate at high speed in the cutting direction at a frequency of 20-40 KHz.Ultrasonic vibration cutting is microscopically a kind of pulse cutting. In a vibration cycle, the effective cutting time of the tool is very short. During most of the vibration period, the tool and the workpiece chip are completely separated, and the tool and the workpiece chip are intermittently contacted. The cutting heat is greatly reduced, and there is no "knife" phenomenon in ordinary cutting.With this kind of vibration cutting, precision machining can be performed on ordinary machine tools. The geometrical tolerances such as roundness, cylindricity, flatness, parallelism and straightness mainly depend on the accuracy of the machine tool spindle and guide rail, and the maximum can reach near zero error. It is possible to use the car to grind, to drill the hinge, and to mill and grind.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 the curve contour, it can be processed by CNC machine tools, machining centers, etc., which can save high-cost CNC grinding machine purchasing cost.
