Imagine this: you're running a precision machining operation, and your team is under pressure to deliver high-quality results—fast. Every second counts. Setup takes too long, traditional clamps are clunky and unreliable, and overheating causes delays or errors. You think, There has to be a better way.
Well, there is. And it's called the EEPM Series Electro-Permanent Magnetic Chuck.
From Problem to Innovation
In the past, workholding solutions were either mechanical—taking up time and space—or electromagnetic—reliable but dependent on continuous power and prone to overheating. Then came the electro-permanent magnetic chuck, a solution that combines the best of both worlds.
This isn’t just a tool. It’s a modern innovation in clamping technology that’s already transforming the way industries work—one setup at a time.
So, What Is an Electro-Permanent Magnetic Chuck?
An electro-permanent magnetic chuck uses a short electrical pulse to switch the magnetic force on or off. Once magnetized, it holds the workpiece firmly in place without needing continuous power. That means:
- Zero energy consumption during operation
- Fail-safe holding, even during power outages
- No heat generation during normal use, keeping your machining accuracy stable
It's a game changer—especially when you're dealing with
heat-sensitive work or complex multi-face machining.
Built to Handle the Heat
One of the most overlooked challenges in machining is temperature. Traditional electromagnetic chucks can heat up and distort the workpiece, affecting precision.
Not the case here.
- For standard machining, the electro-permanent magnetic chuck is built to withstand heat up to 80°C without performance loss.
- For more demanding environments—such as injection molding machines that require fast mold changeovers—specialized models can endure up to 120°C while still maintaining full magnetic force.
This durability makes it ideal for heavy-duty applications where both speed and reliability matter most.
Where Can It Be Used?
This advanced chuck is already in use across multiple industries:
- Automotive – For holding parts during precise component machining
- Aerospace – Where accuracy and minimal repositioning are crucial
- Mold & Die Manufacturing – For reducing downtime during setup
- Metalworking – For clamping ferrous materials securely
- General Machinery Manufacturing – To support a variety of workpieces efficiently
What Machines Is It Compatible With?
You’ll find the EEPM Series installed on:
- CNC Machining Centers
- 5-Axis Machines
- Vertical and Horizontal Milling Machines
- Gantry-type Machines
- Surface Grinders
- Injection Molding Machines (for magnetic mold clamping)
Its versatility makes it a smart investment—one chuck for multiple jobs, reducing the need for extra fixtures or repeated setups.
Why More Manufacturers Are Making the Switch
The benefits are hard to ignore:
- Quick Setup Time – Boosts productivity and shortens machine downtime
- Energy Efficiency – Uses power only for activation, not during machining
- Unmatched Holding Force – Keeps even heavy parts stable under high-speed cutting
- Full Workpiece Access – Allows for 5-face machining without obstruction
- Safe and Reliable – Holds the workpiece even during power failure
- No Heat Distortion – Maintains surface integrity and dimensional accuracy
More Than a Product – A Step Into the Future
This isn’t just an upgrade—it’s a shift in the way we think about clamping. As manufacturing continues to move toward automation, speed, and precision, traditional methods are being left behind.
The electro-permanent magnetic chuck is leading this shift. It’s smarter, cleaner, and more efficient. And with rising global demands for flexible and sustainable manufacturing, it's clear : This is the future of workholding.
