The sPINner small-part deburring machines by Earth-Chain USA are designed to eliminate hand deburring of small, precision parts used in the medical, aerospace and electronic industries. The company says the machines can be used to deburr ferrous, non-ferrous and hard plastic parts. The machines use magnetically activated, stainless steel pin media in soapy deburring solution to remove burrs from internal cavities, slots, holes and blind holes. Parts are automatically demagnetized at the end of the deburring cycle. The machines are available in three sizes for small, medium and large quantities of parts.www.earth-chainusa.com
