We would like to introduce case studies for solving challenges faced by those in charge of developing ultra-high-precision processing machines, such as mother machines. For precision levels that are difficult to achieve with automatic processing machines, we provide manual finishing with high-precision processing machines. Furthermore, for precision that cannot be met through machining, we achieve sub-micron level precision through hand-finishing and lapping processes. Additionally, we conduct thorough quality control using temperature-controlled inspection rooms and measuring instruments that comply with international standards, so you can trust us with your needs.

We would like to introduce a case study on problem-solving for development personnel. We resolved the issue of having only prototype drawings and needing assistance with the design of gauges and jigs. Our company uses 3D CAD, which allows for meetings to be conducted in a way that makes it easy to visualize the shape. Additionally, with a temporary output from a 3D printer, we can have a physical sample on hand, enabling us to eliminate minor discrepancies. We have accumulated know-how from clearing various cases, allowing us to propose more efficient methods. [Challenges] ■ We only have prototype drawings, but we would like assistance with the design of gauges and jigs. ■ We want to measure the prototype. ■ We want to check usability even without a physical object. *For more details, please download the PDF or feel free to contact us.
