3-Step
MDI Series ...
the efficient way to grind
OGM
multi-diameter work
without CNC!
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.
OGM' s Servo Driven
Wlleelllead is designed to
The
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 (Iubed for life) that provides
the utmost in reliability and ease
of maintenance.
Wheelheads
on
Universal models feature :t30°
swivel.
The OGM MDI Series grinds J, 2 or 3
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
• Shih-Plunge / Traverse for fast stock
removal and fine finish
• Traverse with in feed at right end,
'eft end or both ends for fine finish
• Manual Traverse that eliminates the
need for program input - saves time ideal for single workpiece requirements

Okamoto also designed performance
into the OGM r s Workhead.
80th Plain and Universal models
feature a variable speed workhead
with live-dead center standard on
all models. Thisallows for chuck work
application. Variable workhead
swivel from 90° CCW (counterclockwise) to 30° CW (clockwise) is
ideal for grinding
angles or
compound angles. It is standard on
all OGMUniversalmodels.
OGM MD' Mode's
feature a 2-point table
mounted wheel dresser
for precise,
efficient
dressing.

Programmable
Grinding
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 to
input grinding data such as Number
of Different Steps, Table Speed, Air
Cuts, Clear OD (workpiece), SparkOut, Gauging Information. Thispage
also allows the operator to input
offsets for size compensation.
