High-quality manufacturing is achieved through a combination of NC lathe processing and machining!

We manufacture a component known as a mechanical seal. The mechanical seal emerged around the end of the 19th century. It is a mechanism that seals mechanically to prevent leakage from the rotating shaft that penetrates the pressure vessel (casing) in rotating equipment such as pumps and agitators. Research and development progressed as military technology, but it has rapidly evolved in recent years, spurred by the advancement of various industries, including the chemical industry. It is unfortunate that images cannot be included, but due to its mechanical properties, the nature of the mechanical seal prevents oil and water leaks, which means that the geometric tolerances for aspects such as flatness, parallelism, and perpendicularity of the components are extremely strict. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.

Daitokone Seiki Co., Ltd. specializes in precision machining. We are particularly skilled in round-shaped components and excel in the manufacturing of complex processed products that require multiple processes, primarily using NC lathes in conjunction with machining centers. Materials we can process include difficult-to-machine materials such as stainless steel, titanium, copper, and Inconel. Please feel free to inquire regardless of your industry. Since our establishment as a lathe machining company, we have consistently focused on quality and are actively challenging requests for micron-level precision (1/1000mm). We can process up to φ500 in diameter and 600 in length.
