Basic structure and characteristics of ultrasonic cutting knife
Ultrasonic cutting machine is a type of equipment that uses wave energy for cutting and processing. Its biggest feature is that it does not use cutting edges. Or, instead of the traditional edge. Traditional cutting is the use of a knife with a sharp edge that presses against the material being cut. This pressure is concentrated on the edge of the blade, the pressure is very much greater than the shear strength of the material being cut, the molecular bond of the material is pulled apart and it is severed. Because the material is rigidly pulled by a strong pressure, the edge of the cutting tool should be very sharp, and the material itself must withstand relatively large pressure. The soft and elastic materials have a poor cutting effect and are more difficult for the viscous material.
The basic structure is an ultrasonic transducer, horn, cutter (tool head), and drive power. Ultrasonic driving power converts mains into high-frequency, high-voltage alternating current and loses it to the ultrasonic transducer. Ultrasonic transducers are actually equivalent to an energy conversion device that converts input electrical energy into mechanical energy, ie ultrasonic waves. This is manifested in the back and forth movement of the transducer in the longitudinal direction. The frequency of the telescopic movement is equivalent to the frequency of the high frequency AC current supplied by the driving power supply. The role of the horn is to fix the entire ultrasonic vibration system, and the second is to amplify the output amplitude of the transducer. The cutting knife (tool head) on the one hand further amplifies the amplitude and focuses the ultrasound. On the other hand, an ultrasonic wave is output, and the ultrasonic energy is concentratedly input to the cut portion of the material to be cut by using a similar edge of the cutting blade. This part is instantly softened and melted under the action of huge ultrasonic energy, and its strength is greatly reduced. At this point, as long as a small cutting force is applied, the purpose of cutting the material can be achieved. Similar to conventional cutting, the basic components required are the cutting knife and the cutting board. The ultrasonic cutting machine also has two basic structures. Depending on the position of the ultrasonic application, we might as well divide it into an ultrasonic cutter cutter and an ultrasonic cutter cutter. Ultrasonic cutter cutting machine directly loads ultrasonic energy into the cutter, and the cutter becomes a cutter with ultrasonic wave. When cutting materials, the material is mainly softened and melted by the ultrasonic energy, and the edge of the cutting knife can only play the role of cutting positioning, ultrasonic energy output, and separating material. This kind of cutting method is suitable for the cutting of materials such as thick, thick, long and inconveniently arranged cutting boards. Ultrasonic cutting machine is suitable for: raw rubber slitting, tube cutting, frozen meat, candy, chocolate cutting, printed circuit board, industrial, jewellery industry, plastics processing, food processing, printing industry, automobile industry, such as mixing machine output Natural fiber segmentation (subdivision of fine lines), synthetic fiber digging (multi-layer circuit cutting), plastic shell processing, thin synthetic resin varnish (suitable for large areas) All types of paper and base film Origin (China) or hand-held Cutting machine and so on.
The three-point wood drill is a variant of the twist drill, because the conventional twist drill is easy to deviate when drilling on a flat processing surface. When drilling metal, a pilot hole is usually drilled to locate the Drill Bit. But when doing woodworking, we can have a more convenient choice. The straight tip of the three-point woodworking drill is nailed into the wood like an awl to ensure that the drill will not slip.
Wood Working Bits are cutting tools used to remove material to create different kinds of holes in wood materials. In order to create holes drill bits are usually attached to a drill, which powers them to cut through the objects.
Wood working drill Machining accuracy is good, and drilling out of the hole cleanliness is good, small burr,
