• Electric discharge machine

At Beads Co., Ltd., we achieve the processing of brittle materials such as high-hardness ceramics and glass using ultrasonic processing machines. An ultrasonic processing machine converts high-frequency electrical signals generated by an ultrasonic oscillator into mechanical vibrations through an internal spindle. This vibrational power is transmitted to a tool holder closely attached to the spindle, causing a diamond tool at the tip to move up and down at a high frequency (approximately 20,000 times per second). Through this vibrational motion, the diamond particles strike the work surface, crushing the material into fine pieces and performing the machining process. Ultrasonic processing machines are equipped with forward-looking processing technology, enabling not only the machining of advanced materials but also the development of new markets and the pursuit of high productivity. They can directly process ceramics, reinforced glass, and composite materials with excellent properties such as wear resistance, corrosion resistance, heat resistance, and lightweight characteristics.

Our company specializes in high-aspect-ratio deep hole processing (blind and through holes) and grinding, as well as machining (2D to 3D) of high-hardness brittle materials such as ceramics, glass, and cemented carbide using ultrasonic rotary processing machines. We use water as the cutting fluid, which is environmentally friendly. Additionally, the low contact pressure and low heat generation protect both the workpiece and the tool. 【Features】 - Drilling (minimum diameter Φ0.3mm), grinding (flat, outer circumference, shapes), and milling (3D shape processing, pocket processing, groove processing) are possible. - The use of diamond tools allows for the processing of high-hardness materials. - Since only vertical vibrations are applied, it is less likely to cause cracks in the horizontal direction. - 5-face/5-axis machining is also possible. *For more details, please download the PDF or feel free to contact us.
