愛成工業製作所 List of Products and Services

At Aisei Industrial Manufacturing Co., Ltd., we produce shafts used for power transmission, such as steering shafts and drive shafts. Shafts used for power transmission must fit precisely with other machine parts, requiring strict dimensional accuracy. Typically, high precision of ±0.01mm or less is often required. We allow for some tolerance in the dimensions after rough machining to ensure the necessary accuracy can be achieved in subsequent precision machining. We use high-precision measuring instruments for dimensional measurement, surface roughness measurement, concentricity measurement, and conduct strict quality control. [Case Overview] ■ Size: Up to 20mm in diameter ■ Inspection: Surface roughness measurement, concentricity measurement, etc. *For more details, please refer to the related links or feel free to contact us.

At Aisei Industrial Co., Ltd., we manufacture poppets and seats used in hydraulic equipment relief valves and other applications. We focus on high-precision grinding of the seat surface and outer diameter, emphasizing roughness and coaxiality to prevent leaks. Additionally, we use through-feed type machines to perform high-precision centerless grinding with an outer diameter tolerance of less than 5μ, accommodating parts with outer diameters up to φ20 and lengths up to 80. 【Case Overview】 ■ Size: Up to 38mm in diameter ■ Scratch Inspection: Detailed surface scratch inspection using an electron microscope *For more details, please refer to the related links or feel free to contact us.

At Aisei Industrial Manufacturing, we produce spools used in hydraulic control valves. Using Swiss-type multi-tasking CNC lathes, we process parts with a total length of up to 600mm with high precision. We can also consider dimensional changes due to heat treatment during processing. Additionally, our company can simultaneously perform milling operations such as cross holes, chamfering, and eccentric holes, allowing us to accurately process perpendicularity, parallelism, and phase alignment. Please feel free to contact us when you need our services. [Case Overview] ■ Utilizes Swiss-type multi-tasking CNC lathes ■ High-precision processing of parts up to 600mm in total length ■ Sizes: Diameter 8–20mm, Length 20–600mm *For more details, please refer to the related links or feel free to contact us.

We would like to introduce the "cutting and grinding technology" of Aisei Industrial Co., Ltd. Cutting processing is performed based on customer drawings, starting from the material. Using a multi-axis CNC automatic lathe, we can simultaneously carry out milling processes such as cross holes, double-sided machining, and eccentric holes, while accurately processing perpendicularity, parallelism, and phase alignment. Grinding processing requires high precision at the micron level, but thanks to our long-developed technology, expertise, and management system, we achieve stable and high-precision grinding processing. 【Main materials for precision machine parts】 ■ S45C ■ SCM415 ■ SCM435 ■ SUS303 ■ SUS304 *For more details, please refer to the related links or feel free to contact us.
