Ultrasonic vibration milling and compounding: Hard and brittle materials (glass, ceramic, carbide, etc.)

Hard and brittle materials such as glass, ceramics and cemented carbide are difficult to process with traditional methods. However, when high-frequency vibration is applied by conventional milling, drilling, and grinding, that is, a combination of ultrasonic technology and cutting technology, the processing efficiency is greatly improved. DMG’s DMS series ultrasonic processing machines in Germany use a spindle converter to convert the electrical high frequency signal of the ultrasonic generator into 20KHz mechanical vibration motion (longitudinal motion). The vibration amplitude is then amplified and controlled by a pressure regulator, and the vibration is transmitted to a milling cutter, drill bit, or grindstone made of diamond particles by a patented Sauer conical tool holder. The tool undergoes continuous tapping of 20,000 times / sec on the surface of the workpiece during the machining process, separating the surface material of the part into fine particles. Not only is its processing efficiency five times higher than conventional methods, but its surface roughness can reach Ra <0.2 μm. There are two types of DMS series ultrasonic processing machines, 3-axis linkage control and 5-axis linkage control. Spindle speed is 20 to 6000r / min, and tool magazines and automatic tool changers are also available. Therefore, it is a machine tool that has both ultrasonic processing functions and multi-process combined processing such as drilling, milling, and grinding.

KangDing offers the DMG ULTRASONIC 20linear Ultrasonic Vibration Machining Center in Germany. It can be used for ultrasonic vibration milling of all gear materials, hard steel, brittle materials, ceramics, glass and cemented carbide.

In traditional machining processes, the dullness of the cutter increases cutting forces and causes deep damage to the surface of the material. The treatment of carbide or brittle materials is no longer economical. Ultrasonic vibration processing machine technology can solve such problems.

Carbide machining and high speed milling in one machine, unique drive design, X, Y, Z axes are driven by linear motors. All axes are equipped with a 5-axis mechanical design with absolute measurement system, highest dynamic performance, highest accuracy, and compact gantry construction.
