Application of ultrasonic vibration and milling composite machining center

Hard and brittle materials such as glass, ceramics, and cemented carbide are difficult to process using traditional processing methods. However, if high-frequency vibration motion is added to the traditional milling, drilling, and grinding processes, ultrasonic technology Combined with cutting processing technology, the processing efficiency will be significantly improved. The DMS series ultrasonic processing machine tools of the German DMG company use the converter on the spindle to convert the electrical high-frequency signal of the ultrasonic generator into 20KHz mechanical vibration motion (longitudinal motion), and then the voltage regulator amplifies and controls the vibration amplitude. Then through the patented Sauer conical tool holder, all the vibrations are transmitted to the milling cutter, drill bit or grinding wheel made of diamond particles, so that the tool continuously hits the workpiece surface 20,000 times/second during the processing, and the surface of the part is The material separates out in the form of tiny particles. Not only is its processing efficiency 5 times higher than traditional methods, but the surface roughness can also reach Ra<0.2μm. DMS series ultrasonic processing machine tools have two types: 3-axis linkage control and 5-axis linkage control. The spindle speed is 20~6000r/min. It can also be equipped with an optional tool magazine and automatic tool changer, thus becoming a machine that not only has ultrasonic processing functions, but also can A machine tool that performs multiple processes such as drilling, milling, and grinding.

Lansheng provides German DMG ULTRASONIC20linear ultrasonic vibration cutting machining center, which can be used for ultrasonic vibration milling of all dental materials, hard steel, brittle materials, ceramics, glass, carbide, etc.

During the traditional machining process, due to the blunting of the tool and the increase in cutting force, deep damage is caused to the surface layer of the material, making the processing of super-hard or brittle materials no longer economical – ultrasonic vibration processing machine tool technology can solve such problems.

It has super-hard machining and high-speed milling in one machine tool. It has a unique drive design. The X, Y, and Z axes are all driven by linear motors. All axes are equipped with absolute measurement systems. It has the best dynamic performance, the highest precision, and a compact gantry structure. 5-axis machine tool design, optional 4th and 5th axes (swing rotary table), water-cooled USB40 machining spindle with a maximum speed of 40,000rpm, HSK-32S/HSK-32E tool holder with optional internal coolant supply device (IKZ) and chip removal ejector, intelligent process algorithm adaptive control (ADC) and acoustic monitoring (ACC) can automatically adjust the feed in real time to maintain a continuous cutting speed. Specifically the following performance characteristics:

1. Five-axis precision machine tools can be used to process all dental materials

2. Compact, covering an area of only 2m2, machine size: width x height: 800×1,800mm (can pass through 80cm standard door)

3. Integrated rotary swing table using torque technology (standard 4th/5th axis), swing range -20°/+120°

4. Standard HSK-25 spindle, speed 42,000rpm

5. The spindle is integrated with a blowing/suction device*

6. Through the integrated small 4-weight round material automatic clamping device PH2I4* or the linear tool magazine PH2I120* (integrated with 12 discs/80 parts/120 finished parts memories), unattended operation can be achieved during multi-level operations Production

7. Easy-to-operate CNC system Siemens840Dsolutionline
