Lectraline LL1

The Bryant LL1 CNC Grinder is the smallest model in the Lectraline series of machines, and 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.

Designed especially for high production grinding of miniature parts from 0.04" (1.0mm) to 1.5" (38mm) diameter.
