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.
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.
Unlike conventional pipe benders that require fixed-radius dies, our CNC Freeform Pipe Bender allows full control over bend radius and angle through programmed processing. This innovative bending system eliminates the need for frequent die changes and enables highly complex bending operations.
Capabilities Beyond Conventional Pipe Bending
With our system, the following bending operations—previously impossible with traditional pipe benders—are now achievable:
Large-radius bends on the scale of several meters (large R bends)
Continuous variable-radius bends (compound R / progressive R) without intermediate straight sections
3D freeform curves by adjusting the axis angle of compound/progressive bends
Bend angles exceeding 180°
Multiple bend radii in a single continuous process—eliminating the need to change bending dies
Seamless 3D Data Integration
If you provide the 3D centerline data of your pipe (designed with straight and arc segments), we can instantly convert it into our proprietary CNC format using our data converter. This allows for rapid prototyping, much like a 3D printer for pipe bending.
Example Processing Program:
D=42.7
L=120 FF=25.00 FE=25.00
R=100.00 T=90.00 P=0.00 FE=25.00 FF=25.00
R=225.00 T=180.00 P=90.00 FE=25.00 FF=25.00
R=100.00 T=90.00 P=0.00 FE=25.00 FF=25.00
L=120 FF=25.00 FE=25.00
Parameter Definitions:
D = Pipe outer diameter (mm)
L = Length of straight section (mm)
R = Bend radius (mm)
T = Bend angle (°)
P = Axis angle at the connection between different R bends (°)
FF / FE = Relative speed of movement along the XY axis (relative to pipe feed speed)
Production & Custom Processing Available
We offer both small-lot prototype processing and full-scale production using our in-house CNC freeform pipe bending systems.
For inquiries, please prepare your drawings or specific bending challenges, and feel free to contact us!
The production of reflex reflectors—especially for photoelectric switch sensors and bicycles—requires advanced design, machining, and assembly techniques. Only a select few companies worldwide possess the expertise to manufacture such precision molds.

Today, we are pleased to introduce our original in-house product: the “Sine Bar Chuck”, a tilting electromagnetic chuck designed for grinding applications.
At Nissin Precision, we develop functional expansion tools that we ourselves find useful in die manufacturing and supply them to industry professionals.
Below are the key features we would like to highlight:
1. Easy, Fast, and Accurate Angle Setting
⇒ A sine bar is built into the shaft, allowing any desired angle to be quickly and precisely set using gauge blocks.
2. One-Touch Locking Mechanism
To address the common drawback of conventional tilting chucks—dimensional deviation caused during shaft tightening—we developed an indirect clamping mechanism.
This innovation ensures high accuracy with a simple lever operation and allows locking in just a few seconds.
3. High-Precision Shaft and Bearings
⇒ The accuracy during locking is ensured by the “high-precision shaft and bearings.” The shaft is made of special steel, and the bearing incorporates over a hundred steel balls, designed to eliminate play and maintain stable precision.
