Nissin Precision Machines Co., Ltd. operates the robot-equipped digital profile grinding machine DPG-150, a system with extremely limited installations even within Japan.
This advanced equipment enables fully automated processing—from grinding wheel exchange and workpiece exchange to profile measurement and ultra-high-precision machining—without any manual intervention.
By leveraging this cutting-edge capability, Nissin Precision Machines continuously improves operational efficiency and optimizes manufacturing costs.

▪ Conventional Profile Grinding Machines
- Require individual profile charts (drawn contour lines) for each part
- High-precision machining depends heavily on skilled operators
- Repeated measurement and corrective grinding result in significant manual labor time
- Grinding wheel and workpiece changes require additional manual effort
➡ These factors limit productivity and restrict unattended or night-time operation.

▪ DPG-150 Digital Profile Grinding System
- Chartless operation with intuitive programming software
- Projection function enabling up to 400× magnification for accurate profile verification
- Automated measurement system
- Fully unmanned robotic exchange of grinding wheels and workpieces
➡ Enables night-time operation and dramatically improves production efficiency.
