Causes of residual magnetism in machines

• Magnetic tools such as magnetic chucks, magnetic base drills and magnetic dial gauges
• Magnetic particle inspection (MPI)
• Induced magnetism due to machining, abrasion, friction between parts and tools
• Magnetized parts inserted into the machine, such as magnetized gears or bearings
• Prolonged exposure to magnetic fields, such as power lines, earth's magnetic field, etc.

Consequences for the moving machine parts industry

The following damage can be caused by residual magnetism:

• Premature wear on components
• Frosting, pitting or spark marks on rotating parts
• Increased operating temperatures
• Melting or welding of couplings and bearings
• Incorrect sensor values and alarms
• Electrical runout due to uneven distribution of masses
• Temperature peaks
• Incorrect vibration readings

Consequences in production

• Premature wear on components
• Attachment/sticking of chips, tools
• Misinformation from the sensor
• Residual magnetism in the end product
• Measurement errors
• Obstruction of production processes
• Irregularities in the surface
• Wear due to friction
