Lectraline LL3

Originally conceived as an advanced, universal-type tool room grinder, the Bryant Lectraline LL3 has made its mark on many production floors, as well.

Swings parts up to 28" (711mm) diameter and grinds bores to 16" (406mm) in length.
Workhead may be swiveled up to 90° for tapers and rotary face grinding. A sine bar attachment is available to insure accurate angle settings.
Optional Bryant Power-Pivot® workhead permits CNC angle settings with a programmable resolution of less than one arc second.
