For centric cylindrical, orbital pin or form grinding of complex shaft-type components, the workpiece is generally ground between centers. The challenge faced by the workholding device is to transfer the necessary torque, and thus the rotational movement to the workpiece, without deforming it by excessive lateral loads. SwissChuck’s high-precision OVEKA/KA compensating chucks have been originally designed for the machining of crankshafts, a task for which they have amply proven themselves. Over the years, these chucks have undergone continuous improvements such that today, they are perfectly suited for the grinding of all shaft-type workpieces. These chucks have been designed in such a way that the actual clamping force is not applied until all of the chuck’s jaws are sitting flush against the workpiece’s clamping location. The highly sensitive compensation mechanism effortlessly equalizes any workpiece related non-concentricity in the area of the clamping location. The compact design allows an optimal utilization of the machine tool’s overall distance between centers. For this reason, OVEKA/KA compensating chucks are the ideal interface between the workpiece and the machine tool spindle when grinding between centers. To meet the high demands in terms of process stability, the SwissChuck compensating chucks are hermetically sealed against contamination. The hydraulically actuated chuck series Type OVEKA has been equipped with a patented circulating lubrication system (EP1 190 815). All the chuck’s internal components are actively lubricated during each clamping process.
