Lectraform LF1 - CNC Grinding  Machine - Bryant Grinder

The Bryant Lectraform LF1 is a precision CNC multi-surface form grinder.

It's design incorporates years of experience and many time-proven features of our Lectraform LF2, 1M and 45M machines. It is identical in size and the perfect companion to our Lectraline LL1 internal machine especially for grinding various miniature bearing components and similar small workpieces. The workhead can be angled for grinding tapers, flange faces, etc. Most multiple surfaces are ground simultaneously for increased precision and production. The LF1, like the LL1 is "custom" constructed with standard Components™ using a modular design concept for optimum performance at the least investment cost.

The LF1 can be furnished as a single or a dual axis machine. All slides are hydrostatic and continuously supported with dynamic compensation. Their wrap around design uses no mechanical hold-down retainers. The absence of metal-to-metal contact eliminates wear, enhances vibration damping, increases reliability and decreases maintenance. Feed is by a servomotor driven superprecision ball screw.

Consult Factory for applications that exceed limits specified above.
