To explain the behavior of ultrasonic cavities, I have explained that at 20 KHz, a shock wave is generated outward from the central core of the cavity in about 1/40,000 of a second (positive shock wave), and in the next 1/40,000 of a second a shock wave is generated toward the central core (negative shock…続きを読む
Cleaning after buffing has been a challenge in the cleaning industry for 40 years, and removal methods have changed over time. In the past, solvents were often used, but now alkaline cleaners are often used. When using alkaline water-soluble cleaning agents, the temperature should be set to 35°C to 55°C and ultrasonic irradiation should be…続きを読む
I would like to ask a question to the customer. If you can remove burrs and polish without media, using only ultrasonic waves and water, and if you can guarantee the best cleaning quality, and if the product comes out dry, would you still continue to use existing barrel finishing methods? As in the past,…続きを読む
Barrel finishing, widely used in industry, is an old traditional process in which a workpiece and abrasive (called media) are placed in a drum-shaped container, and then an auxiliary agent (compound) is added, followed by water, and the container is rotated or vibrated to polish the surface. The workpiece and abrasive stones rub against each…続きを読む
There are five main types of barrel finishing: fluid, rotary, centrifugal, vibratory, and magnetic. In some cases, solids are added without water, in which case it is called dry barrel, and when water is added to the medium, it is called wet barrel. In this section, we will discuss the mainstream wet type and rotary…続きを読む
Comparison of ultrasonic barrels and existing barrel finishing Ultrasonic barrels have major disadvantages. The major disadvantages are described below. 1, No tradition. This is a major problem. According to my research, there are more than 200 deburring machine manufacturers in Europe and the U.S. In the EU, as far as I can see from their…続きを読む
