EPM Magnetic Chuck
Power is drawn only at switch-on/switch-off — the workpiece stays clamped even through a power outage. High holding force for CNC machining.
About the Product
Unlike conventional electromagnetic chucks, EPM (electro-permanent magnet) technology does not draw power continuously. A short pulse of current is applied to the coils only at the moment of clamping and releasing; once the workpiece is locked to the chuck, the magnetic field is maintained by permanent magnets.
This means that even if a power outage occurs, the part being machined does not shift — protecting both operator safety and part accuracy. On CNC machining centers, milling, and turning setups it gives access to 5 faces in a single clamping.
Every EPM chuck is custom-sized by our engineering team to match your part geometry and machine type.
Advantages
- Workpiece position is held even through a power outage
- No continuous power draw, low operating cost
- Access to 5 faces in a single clamping, less setup time
- Even force distribution for deformation-free, precise machining
- 100% domestic manufacturing, 2-year warranty
