Lectraform LF3

Designed to speed up the production of large, high precision components such as bearing races. These can include ball, cylindrical roller, tapered and spherical designs.

Building on years of proven expertise in production grinding , the LF3 incorporates the latest design and manufacturing concepts to deliver the finest, most effective process capabilities available anywhere around the world.

Designed primarily for plunge grinding, its workhead can be angled for grinding tapers, flange faces and the like. A one-piece, heavily ribbed casting weighing more than 12,225 kg (27,000 pounds) is the base of the LF3. Its strength and torsional rigidity provide a platform with unmatched stability.

To meet the wide range of grinding requirements for large workparts an ever-expanding variety of optional LF3 equipment is available. This currently includes automatic wheel balancer, in-process gaging, powered workhead slides for setup positioning and more. Ask your Bryant representative about the machine and control alternatives now available to best meet your application needs.
