Key benefits

• 

  Significantly improves production efficiency.

  Industry Pain Point:
  Traditional processing relies on manual operation of multiple machines (such as drilling and tapping machines), leading to frequent process switching, which is time-consuming and labor-intensive.

  
  

  Solution:
  Multi-process Integration: A single setup can complete multiple operations, including drilling, tapping, chamfering, and milling, reducing machine changeover time.
  
  High-speed Processing: High spindle speeds (typically reaching tens of thousands of RPM) combined with fast-moving axes (e.g., over 30m/min) significantly shorten processing cycles.
  
  Automation Support: Optional features such as an Automatic Tool Changer (ATC) and automated loading/unloading systems enable continuous production.

  Easily drill and tap complex and irregular workpieces.

  Industry Pain Point:
  Drilling and tapping irregularly shaped or multi-hole workpieces require frequent fixture and tool adjustments, making it difficult to achieve with traditional equipment.

  
  

  Solution:
  Multi-axis Linkage: Supports 3-axis, 4-axis, or 5-axis linkage for processing complex surfaces and inclined holes.
  
  Flexible Programming: CAM software generates complex machining programs to accommodate diverse hole layouts and drilling/tapping requirements.
  
  High-compatibility Fixtures: Compatible with precision fixtures to ensure stable clamping of complex workpieces.

  

  

  Ultra-high drilling and tapping precision, reducing the defect rate to 0.2%.

  Industry Pain Point:
  Manual operation of conventional drilling and tapping machines is highly dependent on operator experience, leading to precision fluctuations, which can result in workpiece scrapping or rework.

  
  

  Solution:
  A leading automotive parts manufacturer previously had an 8% defect rate when machining oil passage holes in engine cylinder heads. After introducing DUOMI CNC drilling and tapping machines, the defect rate dropped to just 0.2%, resulting in an annual material cost savings of $0.5 million.

  Completely free your hands and reduce labor costs.

  Industry Pain Point:
  reliance on skilled workers, high labor costs, and difficulty in recruiting.

  
  

  Solution:
  Automation Production: For example, equipping robots for loading and unloading can achieve 24/7 unmanned operation, reducing reliance on manual labor.
  
  Easy Operation: By using a graphical interface and preset programs, the operational threshold is lowered, allowing ordinary workers to quickly get up to speed.
  
  One person can operate multiple CNC drilling and tapping machines, improving processing efficiency.

  

  

  Quickly respond to orders of any scale.

  Industry Pain Point:
  Traditional drilling machine equipment has long setup times and often requires manual marking for hole positioning, making it difficult to adapt to customized, small-batch orders.

  
  

  Solution:
  Quick Changeover: Production tasks can be quickly adjusted through program switching and modular fixtures.
  
  Flexible Production: Suitable for a variety of products and small-batch orders, meeting the flexible needs of modern manufacturing for drilling and tapping production.

  CNC drilling and tapping machines suitable for multiple industries.

  3C Electronics:
  Drilling holes and tapping screw holes for mobile phones, computers, and 3C digital metal enclosures.
