Three-Jaw Independent Chuck with Cushioned Closure
Introduction
The grinding spindle represents an innovative alternative to the traditional spindle and driver. This device combines the characteristics of both, offering significant advantages in terms of precision and efficiency.
Operation and Features
Fusion of Spindle and Driver
This equipment acts diametrically by pulling like a spindle and centers on the center hole like a driver. This dual functionality allows for greater stability and precision during grinding operations.
Pneumatic Activation
To operate, the equipment uses pneumatic pressure. A solenoid valve sends an air supply that, through internal channels, allows the movement of three independent pistons. These pistons, equipped with cushioned closure, lock the piece and allow it to be pulled.
Technical Details
Materials and Friction
At the end of each piston, there is an insert coated with a specific material designed to ensure maximum possible friction with the piece. This guarantees a firm and secure grip during processing.
Features
- Spindle with interchangeable dead center and rotating body.
- Available in both Morse taper 4 and 5 versions.
- Pneumatic version with working pressures from 2 to 7 bar.
- Diametrical clamping of pieces from Ø3 to Ø30.5 is possible by simply changing the set of 3 jaws.
- The central fixed point is interchangeable and allows working on pieces with different center dimensions.
Conclusion
This grinding spindle represents an advanced and versatile solution, capable of significantly improving grinding operations. Thanks to its combination of functionality and high-quality materials, it offers superior performance compared to traditional systems.
