Neodymium And Ferrite Magnets Manufacturer & Supplier 
Special shaped rare earth magnets, also known as shaped powerful magnets, are magnets designed for special product requirements. Due to their non-standard geometry, special instrumentation may be required to ensure accuracy. Here are some methods and considerations for measuring the dimensions of special shaped rare earth magnets.

The neodymium material used in shaped magnets is relatively brittle, and the processing procedure is also more complicated than that of standard magnets. They are widely used in various machines, precision instruments, special motors, magnetic connectors and other industrial applications.
Special shaped magnets need to be customized and processed in strict accordance with the dimensional standards designed in the drawings, so accurate measuring equipment is needed for inspection after processing. The image measuring instrument, just to meet the various dimensions of shaped magnets on the measurement needs. In addition to the general length and width dimensions, the image measuring instrument can also measure such as magnet flatness, shaped magnet multi-segment curvature, magnet diameter radius, shaped magnet R angle, magnet height, shaped magnet aperture, concentricity of ring magnets and so on. Multi-angle and multi-directional to meet your requirements for the measurement of various sizes of shaped magnets.
Cautions
Tolerance range: The dimensional tolerance range of special shape magnets needs to be within reasonable range, usually ±0.05mm, according to the requirements of customer's drawings to ensure the dimensional accuracy of the magnets.
Positioning and fixing: Before measurement, make sure the magnet is correctly positioned and fixed to avoid movement causing measurement errors.
Measurement Repeatability: Take multiple measurements to verify data consistency and accuracy.
For special shaped rare earth magnets, the use of advanced measuring techniques and tools is essential to ensure dimensional accuracy and product quality.
