Round parts, machining, drive device components, high-precision processing, prototype, mass production.
Supporting Japan's transportation infrastructure with cutting-edge technology.
High-precision and high-strength "round parts (cylindrical parts)" are widely used in drive systems for industrial machinery and railway vehicles. Shafts, bushes, gear components, sleeves, couplings, etc.—all of these are parts that play important roles in rotation, transmission, and support. Our company specializes in the cutting processing of these "round parts" due to our many years of machining experience. ■ Our Strengths: High Precision × Prototype and Mass Production Support 〇 High-Precision Lathe Processing Micron-level dimensional control using NC lathes and composite lathes Support for geometric tolerances such as perpendicularity, coaxiality, and cylindricity Simultaneous processing of inner and outer diameters and keyway machining is also possible Finishing processing after quenching and heat treatment is also supported.

Company information
Daitokone Seiki Co., Ltd. specializes in precision machining. We are particularly skilled in round-shaped components and excel in the manufacturing of complex processed products that require multiple processes, primarily using NC lathes in conjunction with machining centers. Materials we can process include difficult-to-machine materials such as stainless steel, titanium, copper, and Inconel. Please feel free to inquire regardless of your industry. Since our establishment as a lathe machining company, we have consistently focused on quality and are actively challenging requests for micron-level precision (1/1000mm). We can process up to φ500 in diameter and 600 in length.
