Lectraline LL2 - CNC Grinding Machine - Bryant Grinder

With a 10" (245mm) swing and a maximum bore length of 3" (76mm), the LL2 represents a mid-range in the Lectraline series.

This multifunctional machine grinds virtually any type of workpart configuration, including straight and tapered bores, OD's, faces, backfaces, and complex forms.

Many surfaces can be simultaneously, sequentially, or vector ground in a single chucking, thereby saving time and insuring concentricity and squareness.
