The Roeders Drive Technology

Röders Regelungstechnik, Drive Technology

The dri­ve con­trol of the axes is cru­cial to machin­ing results, in terms of both pre­ci­sion and sur­face fin­ish. With con­trol cycle fre­quen­cies of 32 kHz, Roed­ers has been set­ting the stan­dard for years. Over­sam­pling for encoder eval­u­a­tion and numer­ous oth­er spe­cialised func­tions ensure the high­est pos­si­ble axis accu­ra­cy, whilst also min­i­miz­ing ener­gy consumption.

Höchste Konturgenauigkeit

The per­for­mance of the con­trol tech­nol­o­gy can be mea­sured very eas­i­ly, for exam­ple by means of a cir­cu­lar­i­ty test, in which Roed­ers machines con­sis­tent­ly achieve top results in the sub-microme­tre range.

Exakte Temperierung

Roed­ers’ pre­cise con­trol tech­nol­o­gy is not lim­it­ed to the NC-con­trol and the con­trol units for the axes. The tem­per­a­ture of the cool­ing water for the machine is also main­tained at a con­stant lev­el with a very low hys­tere­sis of less than 0.1 K. Where very high stan­dards are required, the hys­tere­sis is even less than 0.02 K.

Smallest Increments

Thanks to Roed­ers’ con­trol tech­nol­o­gy and high-pre­ci­sion opti­cal encoders in all axes, min­i­mum posi­tion­ing incre­ments of 10 nanome­tres can not only be pro­grammed but also achieved in the indi­vid­ual axes.

Con­trary to many rumours, lin­ear motors are ener­gy-effi­cient when used with opti­mal con­trol tech­nol­o­gy, par­tic­u­lar­ly when com­pared to machines with ball screw dri­ves in the axes. Low­er fric­tion in the axes means less heat is gen­er­at­ed and, con­se­quent­ly, low­er ener­gy consumption.
