Saito Seiki will keep moving forward to become a next-level manufacturer of various special purpose machines and equipment.
In addition to providing high quality, high rigidity, low cost, and after-sales service, we are committed to meeting the needs of our customers with reliable technology based on our extensive experience and achievements to respond to rapidly changing trends and diversifying needs.

We manufacture special-purpose machines for cutting and grinding cylinder heads, liners, camshafts, crankshafts, critical safety parts of constant velocity ball joints for axles, and more.
From jet engine testing and inspection processes to assembly for main and tail wings and components, we manufacture equipment and jigs with structural analysis and design components that can withstand Mach speeds.
We manufacture equipment, and jigs used in various testing, inspection and assembly processes under zero gravity for communication, exploration and research satellites. These products are built based on structural analysis and design.

Based on various silicon machining technologies, we also manufacture special-purpose machines equipped with measuring instruments for cutting and grinding, suitable for crystalline materials such as ceramics, quartz, sapphire, SiC, gallium, and indium. We also support test processing of special materials, including difficult-to-cut materials.
