Swiss companyLinearAbrasiveSA thereforeuses thesemi-rotarydrivewithpiston
DRRD from Festo for itsautomatedhighspeedgrindingmachines.Themachineswork
onvariousconnecting rods from threesides,with the infeedandoutput of the
workpieces fullyautomated.
In thepast, the ingressof cuttingandgrindingoil regularly resulted inpremature
failureof thedrives. Using theDRRDmade theprocessmorestable. Aftermore thansix
monthsof continuoususe in threeshift operation, thesemi-rotarydrivewithpiston

innovativebearing concept of theDRRDmakes it sturdyandstable, allowing it to
handle the largemomentsof inertiawithout anyproblem.
Aswell ashigh repetitionaccuracy,whichdidn’t require readjustment evenafter
assembly, theDRRD isalsodistinguishedby itsspeed. It effortlesslysurpasses the
