• High-speed (18,000-50,000rpm) ultrasonic electric spindle
• Two kinds of screw guide protection optional to meet machining needs of hard-brittle materials and metal materials
• Stable high-precision machining with positioning accuracy of 5μm and repeatability of 3μm
• Double-layer workbench design using cast iron and aluminum materials, providing rust resistance while ensuring worktable rigidity
• Expandable tool magazine

Product Highlights

• Gantry frame structure with exceptional stability and lightweight moving components, ensuring enhanced accuracy and improved dynamic performance of the machine tool
• Thermally symmetrical structure designed using finite element analysis (FEM) effectively minimizing thermal deformation impacts while ensuring the high rigidity required for sustained long-term precision
• Employing cast iron with excellent vibration-damping properties, which features outstanding dynamic cutting performance, stability, reliability, and strong applicability
• Continuous enhancement of bed structure rigidity through FEM to achieve the optimal design
• Unique Advantages of Ultrasonic Machining - High Frequency Ultrasonic Vibration Acted on Tooltip (15-70kHz): mitigates microcracking; reduces cutting force and improves machining efficiency; increases tool life; minimizes burring of the workpiece; enhances surface quality
• The machine tool adopts a SIEMENS CNC Controller with LMS Vibration Noise Testing System

Application Cases
Suitable for high-precision and high-efficiency machining of hard-brittle materials (ceramics, sapphire, glass, silicon carbide, etc.), carbon-fiber composites, superalloys (titanium alloy, etc.) and other hard-to-cut materials; suitable for small parts machining and micro-holes drilling.
