• High-precision positioning: 5 μm; repeatability: 3 μm
• Double-layer workbench using cast iron and aluminum for corrosion resistance and table rigidity
• Expandable umbrella-type tool magazine

Product Highlights
Gantry-frame structure provides high stability while moving components are lightweight to improve dynamic performance and machining accuracy.
Thermally symmetrical design validated by finite element analysis (FEM) minimizes thermal deformation to maintain long-term precision and rigidity.
Cast-iron components deliver superior vibration damping and dynamic cutting performance for reliable application across materials.
Bed rigidity optimized through iterative FEM improvements to ensure stable high-precision machining.

Ultrasonic Advantages
Integrated Intelligent Ultrasonic Machining System enhances processability of hard-to-cut materials.
High-speed ultrasonic electric spindle enables micro-machining and high-frequency modulation.
Stable high-precision machining with positioning accuracy of 5 μm and repeatability of 3 μm.
Optional ScCO2 cryogenic through-spindle and MQL systems support clean machining and improved surface integrity.
High-frequency ultrasonic vibration at the tool tip (15–70 kHz) delivers: 1) reduced microcracking; 2) lower cutting forces and higher efficiency; 3) extended tool life; 4) minimized burr formation; 5) improved surface finish.

Application Cases
Designed for high-precision, high-efficiency machining of hard-brittle materials (ceramics, sapphire, glass, silicon carbide), carbon-fiber composites, superalloys (e.g., titanium alloys) and other difficult-to-cut materials.
Well suited for small-part machining and micro-hole drilling in components requiring tight tolerances and excellent surface quality.
