Programmable
Grinding
The O G M M D I Series utilizes a "user-friendly" Fanuc electronic M D I control with a
powerful teach function. Data input is so simple that even operators unfamiliar with
cylindrical grinding can quickly and easily learn to operate the machine and efficiently
and precisely grind up to 10 diameters in a single workpiece set-up. A built-in Manual
Pulse Generator is a real operator convenience in set-up and when grinding in the
manual mode. Another unique feature is a Dress Interrupt Function that enables the
operator to dress the grinding wheel, on demand, at any point during the grinding cycle.
The O G M will automatically stop its infeed, dress, and return to the exact point where
the interruption occurred and resume grinding. In addition, a Cycle Skip Function allows
the operator to skip the dress and roughing cycles and proceed directly to finish grind
plus size compensation.
