For customers struggling with convex/concave round workpieces or micron-level precision grinding, the Nisshin Rotary Chuck is the ultimate solution. This high-precision rotating electromagnetic chuck is designed to enhance grinding efficiency and accuracy.
Developed by our company—a precision press die manufacturer with over 60 years of history—this in-house product was originally created to dramatically streamline our own grinding process. Now, we offer it for sale to fellow metalworking and press processing companies.
Simple & Efficient Add-On
Attaches and detaches easily onto the chuck surface of your existing sine bar chuck or tiltable chuck in small profile grinders or surface grinders.
Perfect for low-volume, high-mix grinding operations, providing flexibility and efficiency.
Proven Applications
Silicon wafer sub-micron grinding
Reduced grinding time for ultra-hard components
The Nisshin Rotary Chuck is a game-changer for precision grinding, helping manufacturers achieve higher accuracy and efficiency with minimal setup effort.
The Nisshin Sine Bar Chuck is a long-selling, best-selling tiltable chuck with a built-in sine bar, with nearly 30,000 units shipped to date.
Developed by our company—a precision press die manufacturer with over 60 years of history—this in-house product was originally created to dramatically streamline our own grinding process. We now offer it for sale to other metalworking and press processing companies.
We recommend using it in combination with small surface grinders from manufacturers such as Okamoto Machine Tool, Giken, Mitsui High-tec, Kuroda Seiko, and NIKKO.
For over 40 years since its release, each unit has been carefully handcrafted by skilled artisans using traditional methods. While this results in a higher price compared to competing products, it offers distinct advantages over later-developed similar sine bar chucks:
Precision and Durability:
The chuck uses a disc brake-like mechanism to secure the半月板 (half-moon plate) fixed to the spindle, ensuring a light clamping feel and precise spindle stopping. There is no loss of accuracy due to aging.
Enhanced Heat Dissipation
Unlike competing products that use simple resin-based fixes for the electromagnetic chuck electrodes, we use traditional soldering, which allows faster heat dissipation during machining.
Thanks to these overwhelming strengths, the Nisshin Sine Bar Chuck has earned a dedicated fan base among professionals who demand the highest precision and reliability.
