What is ultrasonic machining?
ultrasonic machining is a grinding method that uses abrasive liquid rather than direct contact with the tool. Most grinding processes include a working tool that direct contact with a working piece to make the material irritate away. In ultrasonic machining, the liquid filled with abrasive material through their livelihood and the working tool vibrates against abrasives. Abrasive materials affect the working piece and remove the material. Since the tool does not directly affect the working piece, the pressure and tool materials used in ultrasound often differ very much from the materials used in more common machining techniques. This material called porridge is a mixture of free flowing liquid and one or more types of solid abrasive. The liquid part of the porridge is generally water. For some benzene tasks, glycerol or oil may be used instead, but an increase in liquid viscosity often leads to a slower process.
because abrasives used in ultrasonic machine tools must be heavier than machiningMaterial is a common wide range of abrasive. Basic abrasives are often silicon carbide or boron carbide, mostly due to their hardness and low costs. Occasionally diamond dust is used to work with the most difficult materials.
The working tool used in ultrasound differs from the tool used in the standard process. The tool is often made of softer material with high plasticity. This allows Abrasiv to influence the tool, but not damages it as the material is processed. These tools are often too soft for standard machining tasks; They would deform as soon as they touch the work.
The process of machining the piece ultrasonic looks similar to the normal process, but in fact it is quite different. The porridge flows through the working area and creates a connection between the intermediate production and the working tool. The tool vibrates that causes Abrasiva to bounce back and forth between piece and blockmay. Since the instrument deforms, it absorbs the impacts of abrasives while the work develops small cracks. The cracks eventually cause small pieces to fall apart until the machined surface of the work does not match the shape of the work tool.
The most common reason to use ultrasonic machining is when the workpiece is very fragile. On a fragile substance, it causes a standard machine bucket and breakage process. This will generally lead to a destroyed final product. Ultrasonic machining uses thousands of minor impacts and very low pressure to remove the material from the fabric. This rarely leads to a break, even in very fragile materials.
