Evolving high-precision processing that fuses long-cultivated skilled techniques with digital technology.
We, Eisei Seisakusho, are a machining company specializing in high-precision processing, established in 1961. In 2021, we celebrated our 60th anniversary, prioritizing the pursuit of accuracy and continuously honing our technology. We own large 5-axis machining centers, small machining centers, NC lathes, and grinding machines, enabling us to achieve high-precision processing at the micron level across a variety of materials such as iron, aluminum, stainless steel, and copper. Additionally, we are able to achieve high-precision processing of castings, which are typically difficult to work with, through optimal chucking and processing conditions based on years of experience. Recently, we have introduced the latest processing equipment and integrated digital technologies to provide more accurate and speedy responses.
