We, Eisei Seisakusho, are a machining company specializing in high-precision processing, founded in 1961. In 2021, we celebrated our 60th anniversary, prioritizing the pursuit of accuracy and continuously honing our skills. We own large 5-axis machining centers, small machining centers, NC lathes, grinding machines, and more, 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 capable of high-precision processing of castings, which are typically challenging to work with, thanks to our long years of experience and insights into optimal chucking and processing conditions. Recently, we have integrated digital technologies by introducing the latest processing equipment, allowing us to provide more accurate and speedy responses.
