Product Description
  • The sPINner uses magnetized stainless steel PINs as media. The PINs are semi-permanent, and can be used for many years if they are not lost. 
  • The PINs grind parts mildly. The PINs never deform or damage the parts, and never affect the accuracy.
  • The PINs can reach the corners of the parts and grind uniformly. 
  • We have developed various kinds of PINs.
