At a Glance
A table type demagnetizer removes residual magnetism from tools, dies, cutters and hardened components by producing an alternating AC field that a workpiece is passed through. PML supplies the Kanetic KMD-15C, an 80mm-width, continuous-duty (100% ED) table demagnetizer built for tool rooms, press shops and grinding lines.
Once a workpiece has been held, machined or ground against a magnet or magnetic chuck, it retains residual magnetism even after that equipment is removed — a problem for high speed steel, bearing steel, nickel-chrome steel, spring steel and die steel components, which hold magnetism stubbornly and are difficult to demagnetize with standard equipment. PML supplies the Kanetic KMD-15C Table Type Demagnetizer to solve exactly this: pass the workpiece over its alternating demagnetizing field and residual magnetism is removed.
How It Works
A substance shows magnetic properties when its magnetic domains (very small internal magnets) all face the same direction. The KMD-15C applies a damping alternating field to the workpiece, which scrambles the direction of these domains — once they face in various directions, they cancel each other out and the workpiece loses its magnetic property.
How to Use It
- Switch on
The demagnetizer produces an alternating field across its surface.
- Pass the workpiece over the surface
Move it slowly over the demagnetizing surface in the specified direction — for thicker workpieces, pass both the front and rear side over the unit for effective demagnetization.
- Withdraw at least 20cm
Once the workpiece is moved 20cm or more away from the demagnetizer, demagnetization is complete.

Key Advantages
- Continuous Duty
100% ED rating with good heat radiation — withstands continuous power application without overheating.
- Compact and Lightweight
Just 5kg, easy to install and use at a workbench or grinding line.
- Effective on Difficult Steels
Demagnetizes high speed steel, bearing steel, nickel-chrome steel, spring steel and die steel — materials that resist standard demagnetizers.
- Low Maintenance
Durable construction, reliable performance, minimal upkeep.
Where It's Used
Tool rooms, standard rooms, press shops, assembly lines, and grinding lines — commonly mounted at the output of high-speed grinding machines in bearing and roller manufacturing, fitted between roller tables, or incorporated into a conveyor for continuous operation regardless of workpiece size or shape.
- Removing surface residual magnetism from components and tools
- Demagnetizing lapping and honing tools, drills, taps and cutters
- Powder metallurgical processes
- Areas with magnetism-sensitive sensors, e.g. eddy current sensors
- Punches, dies, ground plates and bearings after magnetic-chuck grinding
- Large batches of hardened material after grinding
Frequently Asked Questions
What does a demagnetizer actually do?
It removes residual magnetism left in a workpiece after it's been held by a magnet or magnetic chuck. An alternating field scrambles the workpiece's magnetic domains until they cancel each other out, leaving the material demagnetized.
How do I use the KMD-15C?
Switch it on, slowly pass the workpiece over the demagnetizing surface (both sides for thicker parts), then withdraw it at least 20cm from the unit — demagnetization is complete once it clears that distance.
What materials can it demagnetize?
High speed steel, bearing steel, nickel-chrome steel, spring steel, die steel and similar hardened materials — steels that hold residual magnetism stubbornly and are difficult to demagnetize with standard equipment.
Can it run continuously?
Yes — it's rated 100% ED (continuous duty) with good heat radiation, so it can stay powered on a line without overheating.
What's the effective demagnetizing width?
80mm (the yoke width), which determines the maximum practical width of a workpiece passed over the unit in a single pass.
