High-Precision Magnetic Chucks: Maximum Holding Power for Complex Machining Tasks

Permanent Magnetic chucks are an important part of various machining processes permanently installed in grinding, milling, and turning applications.

These chucks use permanent neodymium magnets to generate a powerful attractive force for the ferromagnetic components without supply of constant current.

Considerations When Choosing a Permanent Magnetic Chuck

Clamping Force

The success of a chuck is sometimes defined by the clamping force it makes. For example our Neox permanent chuck has clamping force that can reach 180 N/cm², it is designed for turning and grinding round shaped workpieces.

Workpiece Size and Shape

Different chucks are created to embrace different kinds of shapes and sizes of the workpieces to be machined. Fine pitch chucks are highly suitable for the small and thin work piece but can also grip substantial works depending upon the cutter used.

Frequently Asked Questions (FAQ)

Q1: What is the difference between permanent magnetic chucks and electromagnetic chucks?

A: Permanent magnetic chucks use high-strength permanent magnets and require no continuous power supply, offering consistent holding force without electricity consumption. They are more energy-efficient and maintenance-free compared to electromagnetic systems that need constant power input.

Q2: What is the maximum holding force of your permanent magnetic chucks?

A: Our permanent magnetic chucks provide a holding force up to 180 N/cm². The actual holding force may vary depending on the workpiece material, surface condition, and contact area. Our technical team can help determine the optimal configuration for your specific application.

Q3: Can permanent magnetic chucks be used for wet grinding operations?

A: Yes, our permanent magnetic chucks feature IP67-rated waterproof construction, making them ideal for wet grinding applications. The sealed design prevents coolant infiltration and ensures reliable performance in wet machining environments.

Q4: What materials can be held by permanent magnetic chucks?

A: Permanent magnetic chucks are designed to hold ferromagnetic materials such as steel, iron, and nickel alloys. The holding force depends on the material’s magnetic permeability and carbon content. Non-ferrous materials like aluminum, brass, or stainless steel (depending on grade) may require additional fixturing solutions.

 Q5: How long does the magnetic force last in a permanent magnetic chuck?

A: Our permanent magnetic chucks are designed to maintain their magnetic force for decades with proper use and maintenance. The high-quality magnetic materials used in construction ensure minimal force degradation over time. Regular inspection and proper handling will help maintain optimal performance throughout the chuck’s lifetime.
