OGM 10'Step MDI Series... the efficient way to grind multi-diameter work

without CNC!

The OGM MDI Series grinds up to 10 different diameters in all cycles, in any order - all in a single set-up. Choose from 4 versatile grinding cycles. • Plunge for rapid stock removal ^ • Stilft-Plunge / Traverse for fast stock removal and fine

finish • Traverse v/ith infeed at right end,

left end or both ends for fine finish • t\Jlanual Traverse that eliminates the

need for program Input - saves time -ideal for single workpiece requirements

The OGM MDI Control Series

Cylindrical Grinders embodies the unique blend of performance features and simplicity of operation that today's fine finisher demands. They are available in Plain and Universal models. Superior quality starts from the ground up with rigid construction that utilizes heavily ribbed Meehanite cast beds with double Vee ways. All components - servo motors, ball screws, control components are of the highest grade. It's our way of assuring that your OGM Series grinder delivers many years of peak performance and accuracy. OGM MDI Series grinders deliver precision, flexibility and operator convenience at an astonishingly affordable price. They are the real value in OD Grinders.

The OGM'S Servo Driven Wheelhead is designed to withstand the rigors of high volume production work, yet deliver consistent fine finish capability to "tenths". Its built-in rapid advance/retract simplifies set-up - a real convenience feature. The wheelhead incorporates a cartridge type wheel spindle (lubed for life) that provides the utmost in reliability and ease of maintenance. Wheelheads on Universal models feature ±30° swivel.

OGM MDI Models feature a 2-point table mounted wheel dresser for precise, efficient dressing.

OI<amotoalso designed performance into the OGM'S Workhead. Both Plain and Universal models feature a variable speed workhead with live-dead centerstandard on all models. Thisallows for chuck workapplication. Variable workhead swivel from 90° CCW (counter­clockwise) to 3CP CW(clockwise) Is ideal for grinding angles or compound angles. It Is standard on all OGfi/l Universal models.

Programmable Grinding

The O G M MDI Series utilizes a "user-friendly" Fanuc electronic MDI 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 wi l l 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.

OD Data Page Used to input grinding data sucti and table reversal position, rough, medium, fine stock allowances, and initial air cut plus clearance amount to next grind.

Program Storage Page Used for naming and storing of up to 21 Individual programs internally, with external program storage to compact flash card capability
