赤塚製作所 List of Products and Services

In the "Thin-Walled Work Processing Idea Book" distributed by our company, we introduce common issues in thin-walled flange work, such as: - "Parallelism is achieved, but flatness is not..." - "Concentricity is achieved, but roundness is not..." - "Roundness and cylindricity are not achieved, and processing distortion is significant..." We also provide tips on how to process while eliminating distortion in cases of magnetic and non-magnetic materials. We hope this will help improve your thin-walled work. At Akatsuka Manufacturing Co., Ltd., we accept inquiries regarding various processing needs. If you are struggling with issues like, "I want to do this kind of processing, but it takes too much effort," or "I have a processing issue that I would like to consult about," please feel free to contact us. ★ You can view the Idea Book by downloading the PDF from the link below.

In the parts processing industry, I hear that many companies are particularly reluctant to work with castings (FC, FCD) recently. The main reasons are that machines and factories get dirty, and changing cutting oil is cumbersome. At Akatsuka Seisakusho, we do not find casting processing troublesome at all, thanks to our efforts such as using cutting oil suitable for machining castings. With our long experience in machining castings (FC, FCD) for machine tool parts, we have reduced the frequency of changing cutting oil in tanks by using cutting oil that does not pose a problem for castings, and we have pursued ways to minimize the adherence of casting chips to finished products, thereby alleviating the hassle of casting processing. Furthermore, we can also handle grinding processes, which are often disliked, even with castings. If necessary, we can provide inspection reports using a three-dimensional measuring machine (Tokyo Seimitsu gantry-type Zeiss head) within the measurable range. Of course, machining from cast iron round bars like dense bars is also no problem. Since we primarily focus on wet processing, please consult us separately if you prefer dry processing. If you have any issues with casting processing, please feel free to contact us!

• Contract manufacturing

At Akatsuka Manufacturing, we accept orders for "medium-sized lathe processing and secondary processing." We mainly manufacture machine tool parts and machine tool-related components. In recent years, we have seen an increase in projects involving non-ferrous metals such as stainless steel and aluminum, and we have also received more inquiries about thin workpieces for both flange work and cylindrical work. In 2017, we introduced a combined cylindrical grinding machine from Taiyo Koki, and in 2020, we utilized a manufacturing subsidy to acquire a high-precision CNC three-dimensional coordinate measuring machine, the XYZAX AXCEL from Tokyo Seimitsu, and we are striving to improve precision every day. Please feel free to leave it to us. 【Details of Services Offered】 ■ Maximum length we can handle: up to 500mm ■ Diameter we can handle: φ150 to 550mm ■ Tolerance we can handle: up to 10 microns (1-micron units are outsourced) ■ Various surface treatments available *For more details, please refer to the PDF document or feel free to contact us.
