At Daitokone Seiki, adjustments of 1/1000mm are finished by skilled craftsmen. They directly touch the materials and make adjustments based on their tactile sense, completing the process. Our strength lies in the fact that we do not rely solely on machine processing; human hands are involved in the manufacturing process. 【Features】 ■ Adjustments of 1/1000mm are finished by skilled craftsmen ■ Directly touching the materials and making adjustments based on their tactile sense ■ Not relying solely on machine processing; human hands are involved in the manufacturing process *For more details, please download the PDF or feel free to contact us.

"What materials will be used for production?" "Where are the areas that will be under load during processing?" "What procedures will be followed as the processing progresses?" Our company has the knowledge and know-how to avoid risks, based on years of experience that takes product considerations into account. Rather than simply seeking efficiency in production, we focus on how to create products that will bring joy to our customers. To achieve this, we possess the technical skills to advance processing smartly.

レアメタル（希少金属）は、航空宇宙・医療機器・半導体など、最先端産業に欠かせない素材で、その加工には高度な技術とノウハウが必要とされます。 当社では、これまでに蓄積してきた金属加工の知見を活かし、難削材であるレアメタルの高精度切削加工に取り組んでいます。 ◆ レアメタルとは？ レアメタルとは、地殻中に存在量が少なく、産出が限られている金属の総称です。代表例としては以下のような金属が挙げられます： チタン（Ti） タンタル（Ta） モリブデン（Mo） インコネル（Ni系合金） ハステロイ（Ni-Mo系合金） ◆ レアメタル加工の難しさとは？ レアメタルは高硬度・高耐熱性・低熱伝導率など、優れた特性を持つ反面、加工が難しい“難削材”でもあります。 ◆ 当社の強み 当社では、以下のような独自のノウハウと設備でレアメタル加工に対応しています。 ✅ 高剛性マシニングセンター／NC旋盤による安定加工 ✅ 専用治具の内製による段取り時間短縮 ✅ 超硬・セラミック工具による最適切削条件の設定 ✅ 難削材専用の冷却・潤滑対策 ✅ 全品3次元測定機による品質保証体制

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.
