Murakami Seiki prides itself on being able to assemble products at a low cost while meeting strict precision standards. The reason for this is that we can handle both parts processing and assembly as a package. In addition to reducing management labor and intermediate margins, we also have innovations in the parts processing stage before assembly. At our Nara factory, established in 2019, we assemble precision measuring instruments, precision machine tools, and semiconductor manufacturing equipment. The quality we deliver is absolute. As proof of that trust, we also measure precision using high-accuracy inspection equipment such as autocollimators. 【Business Activities】 ■ Assembly of precision measuring instruments, precision machine tools, and semiconductor manufacturing equipment ■ Flatness measurement using lasers *For more details, please refer to the PDF document or feel free to contact us.

"Kiritsuke" is the process of finishing the flatness and straightness of sliding surfaces (sliding surfaces) and reference plates of ultra-precision machine tools and measuring instruments with high accuracy. It is an indispensable technique for ultra-precision machine tools and measuring instruments, achieving flatness of less than 2 microns by hand. In machine tools, sliding surfaces prevent deformation caused by wear due to friction and frictional heat as heavy metals move back and forth. This is achieved by artificially creating oil reservoirs, which helps maintain the smooth movement of the table. [Procedure] 1. Apply light-colored dye to the surface to be machined. 2. Spread it thinly and evenly. 3. Perform fitting. 4. The areas where the dye is removed are high. 5. Grind down the high areas. *For more details, please refer to the PDF document or feel free to contact us.
