The NILES-SIMMONS-HEGENSCHEIDT SG-803/2 Axle Grin­ding Machine was con­cei­ved as a sin­gle-wheel angu­lar plunge-cut machine for spe­cial use in grin­ding ope­ra­ti­ons on rail­way axles, fea­turing maxi­mum per­for­mance and utmost relia­bi­lity. Rail­way axles of any size with various dia­me­ters, lengths, and radii are fully auto­ma­ti­cally machined by an auto­ma­ted and high pre­cision grin­ding process.
