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.
