Lectraform LF2 - Multi Surface Form Grinding - Bryant Grinder

Bryant Lectraform machines grind multiple external diameters, faces and forms with the precision of computer control. Their speed and versatility are ideal for grinding bearing components, automotive parts such as front wheel drive and transmission components, and a multitude of other workpieces. They can grind multiple surfaces simultaneously to produce a highest precision and productivity at the lowest possible cost per part.

Standard Lectraform LF2 machines handle workparts from 0.5" to 6" (13mm to 152mm) OD. An extended range version grinds up to 14" (355mm) OD. Either can be a single or dual axis configuration. Single axis models can grind and dress on opposite sides of the wheel, or grind and dress on the same side of the wheel at equal distances above and below its centerline. Two axis models can mount the work spindle and dresser on the workslide and use the CNC for contour grinding and dressing. The two slides are independent and deliver ultimate precision and stiffness because no compound slides are used.

Bryant's Teachable® III CNC makes the LF2 versatility easy to put to work. It is configured specifically for grinding with software based on Bryant's unmatched grinding expertise. Ergonomically intelligent design completes the user friendly package.
