When need toreplace the magnetic pins

When need to replace the magnetic pins? There are several clear signs indicating your magnetic steel pins need timely replacement. First, check if most pins are severely bent, broken or excessively worn after long-term polishing. Second, replace them if workpieces frequently have uneven polishing marks or burrs remain unremoved. Third, swap out pins when rust and heavy oxidation cover the surfaces, which will scratch metal parts. Fourth, low polishing efficiency with unchanged processing time also signals worn pins. Timely replacement ensures consistent polishing results and protects your workpieces from surface damage.
