八州工業 List of Products and Services

At Hachishu Industries, we offer "Precision Machining of Lead Screw Shafts." We have divided our manufacturing division into two sectors. In the low-voltage sector, we have established a temperature-controlled room and excel in ultra-precision cutting of non-ferrous round bars under micron-level management, from prototype to mass production. We handle sizes up to Φ38.0 and various types of threads including 5-start, 8-start, variable pitch, etc. Additionally, we possess quality technology that allows for external tolerances of 3μm, roundness of 1μm, and surface roughness of Ry0.5 or less in our cutting processes. We would also like you to try our friction resistance capabilities. Please feel free to contact us. 【Features】 ■ Established temperature-controlled room ■ Supports sizes up to Φ38.0 and various types of threads including 5-start, 8-start, variable pitch, etc. ■ High-level precision machining technology *For more details, please refer to the PDF document or feel free to contact us.

• Processing Contract

In the automotive sector, we handle bolts related to diesel engine components and oil brakes, focusing mainly on secondary processing after forging for over 20 years, earning the trust of our customers. Our pride at Yashu Industry Co., Ltd. lies in our high-level precision machining technology, and we will continue our unwavering efforts to provide safety and satisfaction to our customers. We are happy to accommodate even a single prototype, so please feel free to reach out to us. For more details, please contact us or refer to our catalog.

• Other Auto Parts

In the electrical department, we have established a temperature-controlled room and specialize in ultra-precision cutting of non-ferrous round bars (SUS, brass, aluminum, titanium) from prototype to mass production under micron-level management. We mainly process lead screws with diameters from Φ2.0 to Φ3.0, as well as lead screws and worm screws in the range of Φ1.5 to Φ15.0, and we also accommodate fixed machining up to Φ38.0. Unusual items include Φ5 lead with a pitch of 32.0, 5-start screws, and variable pitches. In cutting, we possess quality technology that allows for an outer diameter tolerance of 3μ, roundness of 1μ, and surface roughness of Ry0.5 or less. We would also like you to test for wear resistance. For more details, please contact us or refer to our catalog.
