CNC Grinding Machine - LECTRALINE LL1 - Bryant Grinder

The Bryant LL1 CNC Grinder is the smallest model in the Lectraline series of machines. This precision machine is designed especially for high production grinding of miniature parts from 0.04" (1.0mm) to 1.5" (38mm) diameter.

The LL1 is about the same size as the well-known Bryant Centalign® Model B grinder, but with a much greater work range. Updating Centalign® B production lines with CNC is easily accomplished - the space requirements and tooling for the LL1 are virtually identical.
