SIMPLY PRODUCTIVE
The RK Series proves that outstanding precision is not outof you price range. Simple mechanicaldesign combines with advanced features to make these machines remarkablyaccurate and affordable.
CincinnatiMilacron has reduced the number of parts in the RK Series by 42% whileimproving grinding performance.Pneumatics have been removed and most hydraulics have been replaced bysmooth running electric drives. Complexcomputer programming has been replaced by simple state-of-the-art operatorcontrols.
QUICK SETUP AND EASY OPERATION
Onelook at the RK’s standard operators station tells you a lot. Whether it’s the simplest thru feed, or ourcombined ONEfeed version, it is a small unit with relatively few controls. Easy to learn. Easy to set up. Easy to operate.
Theheart of the system is a DMC(Dedicated Motion Controller). Itssimple, direct controls give you the accuracy and consistency of servo controlwith the common sense operation of a manual machine.
Mechanicaldesign of the RK Series helps keep set up easy.The grinding wheel position is fixed, rigidly mounted to the machinebed. An upper/lower slide arrangement,under the regulating wheel and work rest, swivel together with a singleadjustment for quick, accurate adjustment of taper or wheel contact.
Thethru feed control station provides an exceptionally simple interface for quicklearning and easy operation.
PRECISION COMPONENTS
RKmachines are built on an epoxy granite base, selected for its superiorrigidity, vibration damping and thermal characteristics.
RKcenterless slides combine anti-friction ways, brushless AC servo motors,precision ball screws and digital feed back.The results give you two-way compensation with 0.000004 (0.1micron) resolution.
StandardRK truing units are a highly damped design.They provide electrically driven traverse and cam-type profiling.
FILMATICgrinding wheel spindle bearings with hydrostatic lift provide long lasting,hydrodynamic, self-centering support which is consistent under varying grindingloads. Rotational accuracy is 0.000004(0.1 micron). The regulating wheel isrigidly supported at both ends by special hydrodynamic bearings.
RELIABILITY
Simplesystems are easily maintained, have less potential for down-time and requirefewer spare parts.
Withthis in mind, Milacron’s centerless experts researched our extensive library ofdesigns, service records, run-off test results and customer reports. Incorporating such features as hydrostaticspindle lift and S curve slide acceleration to maximize ball screwlife, RK machines apply the latest technology in simple, durable, precisioncomponents.
