Concave-convex precision NdFeB magnets are high-precision special-shaped magnetic components with concave and convex groove structures, step structures, and embedded structures, processed from high-grade NdFeB magnetic materials through ultra-precision machining technology. On the basis of retaining the high magnetic energy product, strong magnetic force, and high temperature resistance of NdFeB magnets, the product designs professional concave surfaces, convex platforms, clamping grooves, and step lines according to the precise assembly needs of equipment, realizing precise embedding, clamping, and positioning between magnets and mechanical parts. This kind of magnet breaks the flat single structure of traditional magnets, and the unique concave-convex matching structure can realize zero-gap assembly and anti-offset positioning, which is specially developed for high-precision equipment assembly and precise magnetic matching scenarios.

In terms of processing technology, concave-convex precision NdFeB magnets adopt high-precision wire cutting, CNC five-axis milling, precision grinding, and deburring integrated processing technology, with the flatness, verticality, and groove tolerance of concave-convex structures strictly controlled within ±0.01mm, reaching industrial high-precision level. The product supports customized design of various concave-convex structures, including rectangular grooves, circular grooves, dovetail grooves, step convex platforms, embedded concave holes, and asymmetric concave-convex combinations, and can be perfectly matched with customer equipment clamping parts and embedded parts. In terms of performance configuration, it supports multiple high-performance grades such as N50, N52, SH, UH, with high magnetic density and concentrated magnetic field, which can provide stable and precise magnetic attraction and magnetic induction signals. The surface is treated with high-precision nickel-copper-nickel multi-layer electroplating, with smooth and flawless surface, strong corrosion resistance, no burrs and edges, avoiding scratch damage to precision equipment during assembly and use.

Concave-convex precision NdFeB magnets are mainly used in high-precision manufacturing, precision instrumentation, intelligent automation, and aerospace fields with strict assembly accuracy requirements. In the precision automation industry, they are used for precision positioning of automated fixtures, concave-convex clamping and fixing of robotic arm grippers, and precise magnetic docking of assembly line positioning components, effectively avoiding displacement and deviation during equipment operation and improving assembly accuracy and production efficiency. In the precision instrument industry, concave-convex structured magnets serve as core magnetic components of precision sensors, detection instruments, and measuring equipment, ensuring the accuracy and stability of magnetic induction data. In the aerospace and military industry, they are applied to precision embedded fixing of aviation equipment parts and magnetic positioning of military precision instruments, adapting to high-standard and high-precision equipment assembly requirements. In the new energy precision equipment industry, they are used for concave-convex clamping and fixing of precision motor parts and embedded positioning of battery components, optimizing equipment structural stability. The unique concave-convex matching structure of the product realizes mechanical limit + magnetic dual positioning, which is far superior to ordinary flat magnets in assembly stability and positioning accuracy, and is a key precision magnetic component for high-end precision equipment manufacturing and intelligent upgrading.
