【Limitations of Conventional Grinding】
Conventional grinding technologies cannot achieve the sub-micron precision required by today’s medical, semiconductor, and precision engineering industries. Standard processes often face issues such as deformation, poor surface finishes, and limited ability to handle ultra-hard materials. As components continue to shrink in size, these limitations make conventional methods insufficient.

【Sanwa Creation’s Nanogrind Advantage】
Sanwa Creation developed its proprietary Nanogrind technology to overcome these challenges. By using diamond grinding wheels and diamond powder, the company achieves nanometer-level precision that exceeds conventional grinding. This unique method ensures stable accuracy, smooth surfaces, and flexibility in design.

Key specifications include:
・Outer diameter tolerance: ±0.1 μm
・Roundness: 0.06 μm
・Surface roughness: Ra 0.0239 μm
・Diameters as small as 0.01 mm
・Workpiece lengths up to 2,000 mm

【Technical Advantages of Nanogrind】
Nanogrind offers capabilities that conventional technologies cannot provide:
・Sub-micron accuracy for advanced applications
・Smooth finishes that reduce friction and wear
・Production of stepped or tapered pins
・Processing of ultra-long shafts without distortion
・Compatibility with tungsten carbide, ceramics, diamond, and titanium

【Applications in the Medical Industry】
Nanogrind supports highly reliable medical components, including:
・Manipulator pins with tips under 1 μm
・Catheter components made from nickel-titanium alloys
