【Limitations of Conventional Technologies】
Conventional machining often fails when processing hard-to-cut materials such as tungsten carbide, ceramics, or diamond. Standard tools cannot achieve the sub-micron precision required for advanced devices. Cracking, tool wear, and poor dimensional stability are common issues. This creates a competitive gap for industries that require extreme precision and durability.

【Sanwa Creation’s Advanced Materials Expertise】
Sanwa Creation specializes in machining ultra-hard and brittle materials using proprietary technologies. By combining centerless grinding, Nanogrind, and precision cutting methods, the company achieves specifications beyond conventional machining.

Capabilities include:
・Outer diameter tolerance: ±0.1 μm
・Roundness: 0.06 μm
・Surface roughness: Ra 0.0239 μm
・Processing diameters from 0.01 mm to 40 mm
・Workpiece lengths up to 2,000 mm
