Electroperm Magnetic Chuck for Milling — AA-50201

An electroperm magnetic chuck is a workholding device that uses a combination of permanent magnets and electromagnets to securely clamp ferrous workpieces for machining operations like milling and grinding. It offers the advantage of high holding force with low energy consumption.

It uses a strong magnetic force to hold the workpiece. A short electric pulse is used to activate and deactivate the magnetic field, but no power is needed to maintain the grip. This makes it a safe and energy-efficient solution.

The main benefits include rapid setup and changeover times, uniform clamping force across the entire workpiece surface which prevents distortion, and clear access to five faces of the job.

On most electroperm magnetic chucks, the magnetic force is not adjustable. The force is determined by the design and size of the magnets within the chuck.

A permanent magnetic chuck uses magnets that are always on and are turned on and off by mechanically shifting the poles. An electroperm chuck uses an electric pulse to switch the magnetism on and off, requiring no power to hold the workpiece.

The AA-50201 is ideal for small to medium-sized workpieces on smaller milling machines. It's a great entry-level choice for general-purpose milling applications.

The AA-50202 offers a larger clamping area, suitable for medium-sized components or for shops that handle a variety of job sizes and need more flexibility than the smallest model.

This model is designed for large workpieces on medium to large milling machines. It's suited for production environments where larger parts are common.

The AA-50204 is the largest model in the 300mm width series, perfect for very large and heavy workpieces requiring maximum clamping surface and stability.

With its wider 400mm base, the AA-50205 is excellent for wider workpieces that need more support, providing enhanced stability for heavy-duty milling.

This mid-size 400mm width chuck is a versatile option for job shops handling a wide range of part dimensions, offering a balance of size and clamping area.

Ideal for large, wide components, the AA-50207 provides a substantial clamping area for maximum stability during high-feed milling operations.

This is the largest chuck in the series, designed for the most demanding applications involving very large and heavy workpieces on large-format milling machines.

The 400mm width chucks (AA-50205 to AA-50208) provide a wider clamping area compared to the 300mm models (AA-50201 to AA-50204). The wider base offers greater stability for wider or irregularly shaped workpieces.

Choose a length that best matches the size of the workpieces you typically machine. It's recommended to select a chuck that is slightly larger than your average job size to ensure full support.

Yes, holding force generally increases with the size of the chuck. Larger models have a greater magnetic pole area, resulting in a stronger overall clamping force suitable for heavier and larger workpieces.
