Introductions

The core dual-axis head components of large domestic five-axis gantry machine tools have an annual demand of about 120 units, but most rely on imports with lead times of up to six months and unit prices as high as NT$4–5 million, resulting in high costs and difficult maintenance. However, domestically produced dual-axis head components still struggle to match the precision of international brands, limiting the profitability and differentiation of aerospace machining equipment.

Technical Advantages and Features

• Cross-platform Domestic Key Modules: Compatible with both commercial and domestic controllers, offering high precision, high performance, and cost-effectiveness. Supports customized smart manufacturing and lifespan monitoring system functions.
• High Torque Output: High torque (horizontal/tilted direct-drive rotary axes up to 1,200 Nm) with high precision at low speed (60 RPM). Utilizes a permanent magnet motor for enhanced efficiency and compact design. At 90° tilt and 0.3 RPM, current ratio is reduced from 35% to 15%.
• High Precision & High Stability: Reduced tilt-axis offset error at 90°, 0°, and -90° positions from 20 μm to 4 μm. Improved horizontal and tilt-axis resolution from 0.001° to 0.0001°. Improved machine geometric accuracy from 40 μm to 7 μm.

Industrial Applications and Business Opportunities

• Industry Applications
  • High-end aerospace components, plastic molding dies, and semiconductor equipment component manufacturing industries.
  • Intelligent Factory.
• Application Examples
  • This technology has been successfully implemented in major Taiwanese machine tool manufacturers to develop customized high-end process equipment. The cost of key components for high-precision dual-axis rotary spindle heads has been reduced by 30%. The product value has increased from NT$9 million for standard 3-axis machines to NT$17 million for 5-axis machines, raising overall machine gross margin to 45%.
