Professional stainless steel pins for magnetic polishing. Flexible dead-angle-free finishing, no damage to precision workpieces, long wear resistance. Ideal for deburring and polishing inner holes, gaps and threads, suitable for mass finishing of precision hardware.
Magnetic polishing steel pins are core consumables for magnetic polishing and grinding machines. Made of high-quality SUS304/SUS316 stainless steel, they feature no magnetic residue, excellent corrosion resistance and high toughness. Driven by a controllable magnetic field, the pins form a flexible abrasive flow that fits all workpiece contours, including inner holes, gaps and thread dead angles. They perfectly solve the precision polishing difficulties of traditional abrasives, and are widely used for deburring, chamfering, oxide removal and mirror finishing of various non-ferrous precision parts.
Available in complete specifications with diameters from 0.1mm to 2.0mm, the pins have uniform thickness and smooth surfaces. They avoid breakage and powder falling during processing, with an ultra-long service life, ideal for mass industrial finishing of complex special-shaped workpieces.
The equipment’s controllable electromagnetic field generates strong magnetic force, driving stainless steel pins to form a high-density, flexible 3D abrasive brush. The pins perform high-speed rotation and floating movement, actively fitting all workpiece surfaces and penetrating hidden areas such as inner holes, gaps and corners. They complete deburring, chamfering, tool mark removal, bright polishing and surface cleaning in one process, achieving dead-angle-free precision finishing.
Dead-angle-free Precision Processing
Ultra-fine pins penetrate micro holes, deep holes, thread grooves and gaps to thoroughly remove tiny burrs and oxide layers without processing blind spots, perfectly suitable for complex precision parts.
Flexible Polishing Without Damaging Workpieces
Physical flexible grinding causes no scratches, collisions or deformation to workpieces. It does not affect the original dimensional accuracy, ensuring a high yield rate for precision parts.
Ultra-long Service Life & Cost-effective
High-quality stainless steel resists wear and acid-base corrosion. It is not easy to break or pulverize during long-term continuous operation. Reusable for 3–5 years under normal working conditions, greatly reducing consumable and labor costs.
Eco-friendly & No Secondary Pollution
Stable material produces no dust or iron residue during polishing. No secondary burrs or contamination are left, leaving workpieces smooth and clean without secondary cleaning, meeting industrial environmental standards.
