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
Hyaluronic acid, which helps keep skin young, is an organic ultra-high polymer with a molecular weight of 2~3 million or more. Because of its large molecular structure, even if it is applied to the skin, it does not penetrate the dermis and cannot be expected to eliminate fine lines and wrinkles or restore moisture. Therefore,…続きを読む
In the chip fabrication process of MLCC multilayer ceramic capacitors, internal electrode paste is applied to dielectric sheets, which are then stacked, and pressure is applied to the stacked items to form a single unit. Next, the stacked dielectric blocks are cut into chip sizes of 1.0 mm x 0.5 mm or 1.6 mm x…続きを読む
