Manufacturing & Customization Capability

Joy CNC's precision stainless steel shafts are manufactured from selected grades such as SUS303, 304, 316, and hardened stainless steels including SUS420 and SUS440C, allowing corrosion resistance, strength, and hardness to be matched to specific application conditions. High-precision CNC turn-mill machining is combined with dedicated fixtures and inspection tools to control dimensional tolerance, concentricity, straightness, and surface roughness in accordance with strict technical requirements.

To enhance wear resistance and service life, optional heat treatment and surface treatment processes, including anti-corrosion passivation, can be applied based on operating conditions such as high-speed rotation or precision sliding. From single shaft components and small-batch custom designs to volume production requiring long-term consistency and supply stability, integrated support is provided from design assistance and rapid prototyping through efficient mass production.
