Product Overview
The EP50 Series is our versatile “all-rounder” magnetic workholding solution.
They are suitable for CNC Machining Centers.
They come with a refined 50ร50 mm magnetic pole grid.
This series bridges the gap between light-duty milling and heavy-slab machining.
Each pole can offer a generated clamping force of 380 kgf.
The EP50 can hold medium-to-small workpieces that larger magnetic chucks often miss.
It is the ideal choice for workshops that require:
– High flexibility for drilling, tapping, and contour milling on workpieces as thin as 10 mm.
Why Choose the EP50 Grid?
The “Sweet Spot” for Size:
Larger poles (like 70 mm) are stronger for massive slabs.
But the EP50โs tighter grid (50 mm) allows for more magnetic contact points on smaller surface areas.
This ensures a secure hold on workpieces as small as 250ร250 mm without needing auxiliary blocking.
Thinner Plate Capability:
The magnetic flux depth of the EP50 is controlled to penetrate approximately 10 mm into the steel.
This allows you to machine thinner plates (10 mmโ20 mm).
Meanwhile, the magnetic field does not penetrate all the way through the part.
And does not interfere with the cutting tool or chips either.
Ideal for Mold Bases & Components:
The dense pole distribution provides exceptional rigidity.
Reduces vibration and chatter during the high-speed machining typical of mold base manufacturing.
Essential “Pro-Tips” for Operators
Using Pole Extensions (Mobile Blocks):
Highly recommend using our optional Spring-Loaded Pole Extensions with this unit.
These extensions lift the workpiece off the chuck face, allowing you to:
– Perform through-hole drilling and boring without damaging the chuck surface.
– Automatically shim uneven stock (like black-bar or rough castings) to create a perfectly flat machining plane.
– Machine on 5 sides freely without clamp interference.
Material Considerations:
The rated holding force (380 kgf/pole) is based on low-carbon steel (like Mild Steel/A36).
Please note that high-alloy steels or cast iron may result in a slightly reduced holding force (typically 20-30% less) due to their magnetic properties.
The EP50’s high flux density helps compensate for this better than standard magnets.
Air Gap Tolerance:
The EP50 design is forgiving of “Normal Operating Air Gaps”.
That means it can securely hold raw stock that isn’t perfectly ground.
However, for the highest precision, ensuring a relatively flat contact surface will maximize holding power.
Standard Supply (What is included?)
The EP50 system is delivered as a “Plug-and-Play” kit.
It requires no internal machine modifications.
