Here is an introduction to examples of machining impellers (blades) mounted on turbines. This is a machining process using A7075 super duralumin, with a size of φ460×50mm. Turbine impellers are difficult to process with standard 3-axis machining, but our company achieves high precision and efficient machining of complex shapes through simultaneous 5-axis control and CAM simulation. 【Case Overview】 ■Industry: Industrial Infrastructure ■Machining Method and Process: Machining of A7075 super duralumin ■Product Size: φ460×50mm ■Lot Size: 1 to 100 pieces *If you are wondering whether such machining is possible, please feel free to contact us. ~ For complex machining with NC lathes and machining centers, contact Ootone Seiki ~

We would like to introduce a case study of high-precision stainless steel ring components used in the mechanical parts of semiconductor manufacturing equipment. Stainless materials such as SUS316 are simultaneously processed using a CNC lathe and machining center, with a size of φ220×30mm. This processing not only enhances aesthetic appeal but also demonstrates practical benefits such as heat dissipation, adjustment of sliding resistance, and visual functional separation. The spiral shape is achieved by effectively utilizing both NC lathes and machining centers, allowing for the coexistence of high-precision rotationally symmetrical shapes and intricate design processing. 【Case Overview】 ■ Industry: Semiconductor Manufacturing Equipment ■ Processing Method and Process: Simultaneous processing using CNC lathe and machining center ■ Product Size: φ220×30mm ■ Lot Size: 1 to 10 pieces *If you are wondering whether such processing is possible, please feel free to contact us. ~ For complex shape processing using NC lathes and machining centers, contact Ootone Seiki ~

We would like to introduce a machining case of ring parts for semiconductor manufacturing equipment. By finishing the S45C quenched material into a complex and three-dimensional shape with high precision, we achieve both functionality and durability within the equipment. The product size is Φ305× overall thickness of 2mm. The design incorporates numerous cutouts and stepped machining to avoid interference with wiring and cooling systems. Even with shapes that boast high machining difficulty, we maintain high reproducibility and quality through a 5-axis machining center and precision jigs.
