Non-round plain bearing wheel spindle
■Heavy grinding and high-accuracy machining possible with shorter cycle time
With dynamic pressure bearing structure, retention is done with wedge-shaped oil membrane pressure produced in the internal portion of the bearing by rotating the grinding wheel spindle. Retention force with unparalleled strength of 1 ton makes powerful grinding possible. High-accuracy grinding of �0.01 µm is achieved with grinding wheel rotational accuracy. The grinding wheel spindle has no metal contact and performance can be retained semipermanently.
Okuma's precision servo and low-friction slide guideway
The below shows that reliable following is achieved without trial feed even with super slow command that moves the wheelhead 1 µm in 100 sec.
Basic technology makes powerful,high-accuracy grinding possible

Thanks to rigid structure from a thick bed and diagonal rib placement, stable machining is possible even with raised cutting conditions, leading to increased productivity.
Stress analysis with FEM analysis
With good wheelhead follow-up accuracy and taper and R profile grinding, workpiece shape accuracy is also improved.

Dressing during loading/unloading of workpiece possible
Dressing during workpiece loading/unloading becomes possible with a loader and cycle time
is decreased without movement of material on the table because of X, Z wheelhead traverse.
Operability and comfort
■Fewer key operations for workpiece and diamond (wheel/tool) origins●Decrease of � 70% compared with previous
machine
■Full-enclosure shielding standard●Provides a superior environment to minimize
coolant scatter and noise.
■Tailstock with manual taper compensation●Taper changes accompanying tailstock travel
can be regulated easily.
■NC bed tooling (Optional)
●Any-position diameter gauging is possible with a tooling base for NC positioning set longitudi-nally in front of the table and a mounted sizing device. This is effective in cases when you want to use the sizer with a multistep workpiece.

Main optional accessories
■Coolant separatorSludge is discharged to outside. With standard specifications there is only a magnetic separator (Ferrite magnet), but in SKD and SCM materials with weak magnetic properties combined use of a paper filter or a powerful (rare earths) magnetic separator are effective.
■Direct sizerWorkpiece OD dimensions are managed with in-process gauges during machining.
■Rotary dresserSelect for mass-production machining or when using CBN grinding wheel.
■NC locatorCompensates for variations in workpiece length reference position
■Dresser (diamond tool)Select depending on shape dressing and use, such as mass-production machining.
■Supply oil hole centerOil is supplied to reduce friction and heat in the center and workpiece center hole.
■Wheel balancing stand/balancing arborGrinding wheel, wheel flange, and balancing arbor are mounted and static balance of grinding wheel on rail is maintained.
■Pressure tailstock (long travel)When workpiece length changes, the tailstock main body position of standards tailstocks needs to be moved, but when there are several different workpiece lengths the tailstock quill position is checked and determined with an internal AbsoScale. With work-piece differences of within 100 mm the tailstock does not move and is maintained constant with support force. Travel 170 mm
Magnetic separator Combination magnetic separator, paper filter type
■Cam lock chuckThis is a chuck in which cam shaped jaws grab workpiece and clamp more strongly as the grinding load becomes larger.
■Nipper chuck (cartridge)Clamped with V block and held with spring force. Can respond flexibly to differences in workpiece diameter.
■DogWorkpiece is clamped with bolts, and hooked on pin in V section for drive. (available only with manual machines)
■Constant sizer coolant supplyWith this specification, thermal deforma-tion is minimized by constantly supplying the sizer with coolant.

Compact CNC in pursuit of better price-performance OSP-U20G
■ Far less trouble-shooting downtimeAs soon as an alarm is indicated, the NC has the printer (optional) print out a hard copy of the information needed to trouble-shoot the problem. You can fax the copy right to the service center and spare yourself the usual long and involved phone calls.
■ Provides “real time” results informationThe CNC compiles actual production data as it happens and outputs it to the screen. ● Operators can use the data make to improvements● Accurate up-to-date information at your fingertips ● The end-user, armed with a PC, can manage things right on
the spot in the way he or she wished.
■ Reduced setup change timeBy streamlining the file operation order, input/output of part programs takes far less time. End-users can use a conventional PC to display their own operation procedure up on the NC screen.

Help function
Okuma has developed their systems with next-generation flash memory for the most reliable CNCs available. Use our NC controllers for cutting-edge functions and performance.
An assistant for key operations
When you cannot find specified G code/M code etc. in part programs, one touch on 'Help' key enables you to see the content of each code on NC display, efficiently assisting you in machining operations. When an alarm is activated, the 'Help' key will display the content of alarm on NC display, assisting the operator in troubleshooting.
