EP50 Series (50×50 mm Pole)

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 50×50 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 EP50’s tighter grid (50 mm) allows for more magnetic contact points on smaller surface areas. This ensures a secure hold on workpieces as small as 250×250 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 mm−20 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. 1). 1x Magnetic Chuck Module: Fully sealed, water-proof, and oil-proof (IP67 rated). 2). 1x Electro-Permanent Controller: Manages the Magnetize/Demagnetize cycles safely. 3). 1x Handheld Remote: Allows the operator to activate the chuck from a safe distance. 4). Cabling Set: Includes heavy-duty 3-meter power and control cables with quick-disconnect waterproof connectors. Customization Options Extended Cabling: For large Gantry or Double-Column machines, we can provide custom cable lengths to reach your control station. Voltage Requirements: Compatible with standard industrial voltages. Please specify your region/machine voltage upon ordering.
