OGM 3-Step MDI Series ...the efficient way to grind

multi-diameter workwithout CNC!

The OGM MDI Series grinds J, 2 or 3different diameters in all cycles, in anyorder - all in a single set-up.Choose from 4 versatile grinding cycles.• Plunge for rapid stock removal• Shih-Plunge / Traverse for fast stockremoval and fine finish

• Traverse with in feed at right end,'eft end or both ends for fine finish• Manual Traverse that eliminates theneed 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. OGMMDI 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 DrivenWlleelllead is designed towithstand the rigors of high volumeproduction work, yet deliverconsistent fine finish capability to"tenths". Its built-in rapid advance/retract simplifies set-up - a realconvenience feature. Thewheelhead

incorporates a cartridge type wheelspindle (Iubed for life) that providesthe utmost in reliability and easeof maintenance. Wheelheads onUniversal models feature :t30°swivel.

ProgrammableGrinding

The OGM MDI Series utilizes a "user-friendly" Fanuc Powermate-G 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 3 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 OGM 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.

Grinding Data Page Used toinput grinding data such as Numberof Different Steps, Table Speed, AirCuts, Clear OD (workpiece), Spark­Out, Gauging Information. Thispagealso allows the operator to inputoffsets for size compensation.
