A well-reputed OX series incorporatesthe CNC system. Highly sophisticatedoriginal software matching the hardwarepresents you with ideal grindingmachining.OKAMOTO's precision grinding machine seriesgeneralizes that high accuracy and high effi-ciency are common to grinding machines. Vari-ous features ranging from basic items of preci-sion grinding machine such as unique andrigid column structure and thermal deviation tomaintenance free systems and a variety ofoptional specifications as well as originaldetail design for high grinding efficiency, highmaneuverability based on the ergonomics, andfail-safe mechanism have led to an evaluationthat "OKAMOTO's today's mechanisms arestandards of tomorrow". Now, we are facingthe 21 centuries. OKAMOTO is committing todevelopment of unique rr.""~',"""'!'."-;;;;;;;;:~::;;softwares that canrelease highly completemachines fromspecialized operatorswith the emphasis puton the high precisiongrinding that does notrequire skilled operatorsthrough establishmentof next-generationtechnology.

Guideways most suitable for functions ineach part

Vertical: Guideway of H-shaped structure hav-ing 3 taper gids, subjected to Turciteprocessing.

Cross: Use of flat cage for V-V guideway withhigh feed accuracy.

Longitudinal: V-V guideway made of cast ironthat maintains stable accuracy for along period of time.

Reinforced maintenance-free orienteddesign

Maintenance-free features are further improvedby employing AC servomotors, non-contactswitches, permanent grease sealed wheel spin-dle. The use of ladder display function facili-tates inspection, and has realized simplifiedmaintenance work, eliminating troublesomejobs and time loss.

Standard specification ofcountermeasures against thermaldeviation that remarkably reducestemperature change.

Various measures including air cooling oilcooler and heat insulating covers are usedagainst thermal deviation, so that influence ofheat on machining is restricted to the mini-mum.

PROGRAMMING NOT NECESSARY. ONISOFTWARE TO START HIGHLY EFFICIEI

IThe built-in versatile grinding pattern cansupport any kind of grinding applications.

Only selection of a grinding pattern and form patternfrom the built-in menu and input of conditions andfinal dimensions can start machining immediately.Asgrinding pattern,you wi11select either of (1) Incrementplunge,(2)Continuousplunge,(3)Traverseor(4)CrissCro-ss, then one of the six form patterns shown below.A combination of these patterns can clear generalgrinding needs,and additional programmingis thereforenot required.

Conversational input system

ISelection of a grinding cycle with justa finger's touch.

Either of four grinding cycle patterns that willsuit the purpose can be selected with a singlefingertip operation. Then, the machine exe-cutes the optimum grinding including interme-diate dressing. Of course, optional dressingduring an automatic cycle is available.

ITroublesome operations are allundertaken by the CNC.

Sizing and position data can easily be input.Owing to the teaching system, simply pressingthe CYCLE START switch completes input.Operation can start with arbitrary position, thuseliminating positioning of machining start pointand idle time. Additional troublesome opera-tions are all undertaken by the CNC system.

LY INPUT OF DATA ACTIVATES UNIQUEMT CNC GRINDING.

IEasy Operation not Requiring a SkilledOperator

Conventionally, it has been seemed that thedegree of completion of a precision grindingdepends on the experience and sense ofskilled operator, and also the CNC machiningrequires time and manpower for programming,and therefore, it is still far from true rationali-zation.OKAMOTO's new CNC series provides a solu-tion for this subject by developing unique soft-wares. Only learning simple basic operationsallows even unskilled operator to operate themachine with the maximum grinding perfor-mance of the DXNC series.

IHigh Reproducibility Makes aContribution to Rationalization and QC.

Freely saving and reproduction of grinding dataprovide a merit in CNC grinding. The use ofRS-232-C interface enables saving and repro-duction of machining data. This function iseffective for unscheduled small-lot machiningand also it can reproduce the same machiningeven if the operator is substituted. In additon,simultaneous operation of several machinescan attain rationalization and quality controleasily.

Remarkably Reduced Cycle Time.

Simulation

New CNC series provides easy-to-operatefunctions, not requiring programming. The use

of the conversational input system (optional)starts machining by only answering the promptdisplayed on the CRT screen (for about 5 min-utes) since various machining patterns arebuilt in. The above figures show a comparisonbetween G code input and pattern data input;4H 35M in G code input is reduced to 2H 5M,less than half.

INew Operation System ImprovingMachine Image.

Almost all switches, keys and lamps arecentralized to the movable operation unit.Easy-to-operate and visible panel layout deter-mined by taking operation procedure and fre-quency into account. Just a finger's touch ofsheet key changes the machine image.
