Adjustable NdFeB Magnet Magnetic Square for in Engineering And Manufacturing

Overview

The Adjustable NdFeB Magnet Magnetic Square is a versatile engineering tool designed for precision positioning, clamping, and alignment in manufacturing processes. Constructed from N42-grade NdFeB magnets encased in a CNC-machined steel housing, this magnetic square features adjustable magnetic force (0-100% output) and a 90° V-groove design, enabling secure workpiece holding and angular alignment in milling, welding, and assembly operations. The dual-pole design allows quick switching between "on" (full magnetism) and "off" (zero residual magnetism) states, improving safety and efficiency in metalworking environments.

Features

Adjustable Magnetic Force:

Dual-Mode Operation: A rotating handle controls magnetic flux, providing 0-500N holding force (for 50x50mm square) to suit delicate alignment (20% force) or heavy clamping (100% force).

Zero Residual Magnetism: When switched off, the magnetic circuit is closed, leaving no residual magnetism on workpieces, critical for post-processing steps like painting or plating.

Precision Engineering Design:

90° Angular Accuracy: Laser-calibrated V-groove ensures ±0.05° alignment precision, ideal for welding jigs and CNC machine setups.

Durable Construction: The steel housing (hardness HRC 45) resists impacts and abrasions, with replaceable NdFeB inserts for long-term use (insert lifespan: 5+ years under normal conditions).

Safety and Convenience:

Ergonomic Handle: Requires 15N·m torque to switch modes, preventing accidental activation in vibration-prone environments.

Anti-Slip Base: Textured rubber pads reduce slippage on oily or smooth surfaces, supporting workpieces up to 20kg at 100% magnetic output.

Application

Welding and Fabrication: Holds steel plates at 90° for precise T-joint welding, reducing setup time by 40% compared to mechanical clamps.

CNC Machining: Secures workpieces on milling machines, enabling quick fixture changes while maintaining positional accuracy (repeatability ±0.02mm).

Quality Control: Uses the V-groove for angular checks on shafts and pipes, replacing traditional gauges with a magnetic self-centering solution.

Assembly Lines: Positions electronic components during soldering or bonding, ensuring 90° alignment for connectors and heat sinks.

FAQ

Q: Can the magnetic force be fine-tuned for delicate parts?

A: Yes, the adjustable handle allows 10% increments, enabling 20N force for aluminum parts up to 500N for steel components.

Q: Is the steel housing magnetized when the square is "off"?

A: No, the housing acts as a flux concentrator; when off, all magnetic field is contained within the housing, leaving the exterior non-magnetic.

Q: What is the maximum workpiece thickness it can hold?

A: The 50x50mm square holds workpieces 2-20mm thick; larger models (100x100mm) accommodate up to 50mm thickness at full force.

Q: Can it be used on non-ferrous metals like aluminum?

A: No, magnetic force requires ferrous materials (iron, steel). For aluminum, use mechanical clamps or adhesive fixtures.
