About

About ISS Dainichi Co., Ltd. Founded in 1948 and guided by the philosophy of 'even smaller and more precise,' ISS Dainichi has addressed the unique challenges of micro-hole and precision machining. We have contributed to a variety of industries, including semiconductors, aerospace, and medical. Our strength lies in micromachining, small hole drilling, and deep hole drilling. With over 75 years of commitment to innovation, we are prepared to meet a wide range of micromachining needs. We offer capabilities such as drilling holes as small as 0.01 mm (0.393 mil) and achieving 100:1 aspect ratios for φ0.10 mm (φ3.937 mil). We specialize in honing that achieves surface finishes of Ra less than 0.02 µm (0.79 μmil). Additionally, precision machining on automatic lathes produces parts as small as sesame seeds. We welcome prototype requests. Our facilities are equipped to meet your production needs, whether it's a single piece or high volume. Bring us your challenges!
