Technology / product information

At YAMAGUCHI VIETNAM, we perform high-precision lathe machining of small shafts and mechanical components made from stainless steel (such as SUS304), achieving tolerances of ±0.01 mm. Below is an example product that demonstrates our machining capabilities.
[Product Specifications]
Material: Stainless steel (SUS304, etc.)
Dimensions: φ24 mm × L28 mm
Machining tolerance: ±0.01 mm
Application:
[Machining Processes]
Outer diameter roughing and finishing: Precision shaping from SUS304 stainless steel round bar
Inner diameter machining & U-groove cutting: Simultaneous machining with dedicated cutting tools
Side-threaded hole machining (optional): Small screw holes (M-thread) can be added if required
Quality assurance: 100% inspection using CMM (Coordinate Measuring Machine) ensures concentricity and dimensional accuracy
Equipment Used: Mori Seiki / Citizen / Okuma CNC lathes. Capable of stable quality and mass production even with lightweight and machinable materials like SUS304 stainless steel.
