Turbine material (Ni-based special material) rotor parts [curved + thin-walled processing]

Ni series special material rotor blades ★ With know-how to prevent warping and twisting, we can confidently manufacture even curved and thin-walled designs!

This product is a part of a turbine rotor blade. Due to its free-form curves and thinness, the key point in manufacturing is to consider warping. Additionally, know-how is required for the setup methods to prevent warping. Our company possesses the know-how to prevent warping and distortion based on our experience and track record. If you are looking for manufacturers who can handle curves and thin-walled processing like this product, please feel free to contact us. At Imabashi Manufacturing, we also accept inquiries regarding design-related issues and processing consultations, in addition to regular estimates, so please don't hesitate to reach out!

High-precision outer diameter machining of S45C medium carbon steel using an NC lathe. Manufacturing cylindrical cylinder parts for power generation and energy equipment. One-pass finishing of stepped inner diameters.

We would like to introduce a machining case of cylindrical cylinder parts for power generation and energy equipment. Using S45C medium carbon steel, which has a balanced strength and machinability, we performed high concentricity outer diameter machining with an NC lathe, with a size of φ200×400mm. We minimized tool changes with a one-shot finish of the stepped inner diameter and handled the R processing of the stepped section all at once. The manufacturing is conducted under a temperature-controlled environment to minimize temperature fluctuations. 【Case Overview】 ■ Application: For power generation and energy equipment ■ Machining method and process: High concentricity outer diameter machining using an NC lathe ■ Product size: φ200×400mm ■ Lot size: 5 to 30 pieces If you are wondering whether such machining is possible, please feel free to contact us. ~ For complex machining with NC lathe and machining center, contact Ootone Seiki ~
