Nissin Precision Machines Co., Ltd. specializes in the manufacturing of precision dies, including deep-drawn motor case components and dies for semiconductor parts.
For punch profile machining—directly linked to final product accuracy—the company primarily employs high-precision profile grinding. Even extremely small or complex geometries are finished with exceptional accuracy, supporting stable and repeatable press processing through meticulous attention to detail.

▪ Punch Machining Examples / Capabilities
- Feature size below 1 mm → Tolerance: ±0.002 mm
- Straight + corner radius (R) geometry → Tolerance: ±0.001 mm
- In addition to dimensional accuracy, the exact center position of radius (R) features is precisely measured and machined.
➡ This comprehensive precision control aims to achieve near 100% reproducibility during press operations.
