How Ferrite Arc Magnets Are Precision Ground: 3 Common Machining Methods

Arc magnets (also known as ferrite magnet segments) require precise grinding to meet the dimensional and surface finish requirements for motor assembly. Here’s a breakdown of the three most common grinding processes we use at Gaomu Magnet:
🔹 1. Basic Manual Grinders
Suited for small-batch production and prototyping
Low initial cost, but highly dependent on operator experience
Best for applications with less stringent tolerance requirements
🔹 2. Single-Stage Grinders
Higher automation than manual grinders
Completes one precision operation (inner/outer arc or end face) per cycle
Delivers consistent accuracy for medium-volume orders
🔹 3. Through-Feed Continuous Grinders
Fully automated, high-volume solution
Performs 6-sided forming grinding in one continuous pass
The standard choice for mass production at large-scale factories
At Gaomu Magnet, we tailor our grinding strategy to your project’s scale and precision needs, from low-volume custom samples to high-volume motor-grade magnet production.
